Project Finance 2023

Last Updated November 02, 2023


Law and Practice


Nagashima Ohno & Tsunematsu is one of the foremost providers of international and commercial legal services based in Tokyo. The firm has more than 560 lawyers, including 46 experienced foreign attorneys from various jurisdictions. Its overseas network includes offices in New York, Singapore, Bangkok, Ho Chi Minh City, Hanoi, Jakarta and Shanghai, and collaborative relationships with prominent local law firms throughout Asia, Europe, North and South America and other regions. The firm regularly advises leading power utilities, trading companies and investors on their energy projects, including all associated regulatory matters. It also advises financial institutions on financing for these projects. The firm has dealt with a number of renewable power projects since the introduction of the feed-in tariff in Japan.

The major players differ slightly depending on the type of project.

  • Conventional private finance initiative (PFI) projects (ie, availability-based accommodation projects): these are occupied by domestic players, with international players rarely seen. General construction companies and real estate developers are active as sponsors, while Japanese regional banks are active as lenders.
  • Concession projects: the above trends for conventional PFI projects are also seen in concession projects, except that Japanese trading companies are more active and, in the case of airport concessions, international airport operators are also active. Japanese major banks typically take the lead in organising syndicates of Japanese banks, but non-Japanese financial institutions sometimes participate in projects in which international sponsors are involved.
  • PFI/PPP projects: a unique characteristic of PFI or public-private partnership (PPP) projects in Japan is that local companies in the region where the project is located are often invited to hold a minority interest in the project company as an expression of the sponsors’ eagerness to contribute to the local economy. As such, it is not uncommon for a project company to have up to ten or more shareholders.
  • Power projects: Japanese trading companies, power companies and other domestic and international developers are active as sponsors in power projects, particularly renewable projects. Japanese banks are dominant as lenders.
  • Project finance: in Japan, project finance is dominated by Japanese banks, with very limited space for non-Japanese financial institutions. Project bonds are also uncommon in this market.

The PFI regime was introduced in Japan in 1999 when the Act on Promotion of Private Finance Initiative (Act No 117 of 1999, as amended – the “PFI Act”) was enacted. Many availability-based accommodation projects have since been implemented (eg, schools, hospitals, school catering service facilities and libraries). The PFI has been welcomed by local governments as a tool to spread the cost of investing in infrastructure over 20–30 years, although it has sometimes been targeted by critics who argue that it does not provide value for money.

Against that background, the PFI Act was amended in 2011 to introduce a concession scheme, under which a concessionaire is authorised to collect a commission, toll, fee or other consideration from the general public for their use of the infrastructure that the concessionaire operates. In this way, the concession scheme is considered a flexible tool for structuring a project where the private sector assumes all or part of the revenue/demand risk. Concession schemes were intended to be used to privatise the operation of certain infrastructure in which the legal title cannot be transferred to the private sector due to national security or other political reasons. The first infrastructure targeted was airports. Since Kansai International Airport and Osaka International Airport were privatised through a 44-year concession with the use of approximately JPY200 billion of project finance, many airports have been privatised under concession schemes.

The national government is considering privatising other infrastructure using concession schemes, such as water facilities, so-called MICE facilities (ie, facilities for Meetings, Incentives, Conferences and Entertainment), stadiums/indoor sports facilities and hydropower plants.

The PFI Act provides the procedural requirements that the public sector must follow to initiate a PFI project and the substantive rights and obligations granted to a private sector company under the PFI regime. However, the PFI Act itself does not legalise the operating and maintaining of public infrastructure by the private sector; this needs to be legalised by separate legislation. Accordingly, a concession scheme will not be available unless appropriate legislation has been enacted for the relevant public infrastructure. To date, such legislation has generally not been passed in respect of toll roads.

In addition to the general PFI/PPP regimes under the PFI Act, the Port and Harbour Act (Act No 218 of 1950, as amended) and the Urban Park Act (Act No 79 of 1956, as amended) each provides for a PPP regime applicable to specific public property.

Further, based on the Japanese national government’s long-term strategy for carbon neutrality, a new PPP structure is scheduled to be introduced in late 2023 under which a public auction (Long-Term Carbon Neutralilty Capacity Auction) will be held to select project companies for certain areas of renewable energy businesses, such as energy storage services and biomass power plants, to which availability-based payments will be paid by the Organization for Cross-regional Coordination of Transmission Operators (OCCTO), a statutory institution that every electricity business operator is required to join as a member, for up to 20 years, subject to the project companies fulfilling certain requirements stipulated by OCCTO for the purpose of achieving the governmental goal of stabilising domestic electricity supply and demand.

The Japanese project finance market has some unique characteristics; understanding these characteristics will help in procuring project finance in Japan. Perhaps the most unique characteristic is that the structuring of project finance in Japan is largely influenced by asset finance – real estate finance in particular. That tendency is stronger in solar and onshore wind renewable energy projects, which have boomed since the feed-in tariff (FIT) was introduced in Japan in 2012. The “bankruptcy remoteness” of a project company and tokumei kumiai (TK) investments in project finance are both concepts imported from real estate finance practice.

Bankruptcy Remoteness

The following structure is typically adopted to achieve bankruptcy remoteness for a project company:

  • a godo kaisha (GK), which is one of the possible corporate forms of a company in Japan and is described further below, is selected as the project company form;
  • an ippan shadan hojin (ISH), which is a form of legal entity for non-profit organisations, is selected as the GK’s only legal equity holder;
  • the ISH is independent from the project sponsor; and
  • all relevant persons (generally, contractors, suppliers and offtakers) are required to waive their right to file in an insolvency proceeding against the GK.

An ISH is considered independent from the project sponsor if all equity interests in the ISH are held by an independent accounting firm and if the corporate officer positions of the ISH are all assumed by accountants who are independent of the project sponsor. Usually, an ISH is incorporated with nominal funding, such as JPY100,000. Furthermore, GKs, ISHs and their respective officers need to deliver to project finance lenders a “non-petition letter” undertaking not to file in any insolvency proceeding with respect to the project company. By doing so, project finance lenders seek to make the project company as remote as possible from legal insolvency proceedings.

TK Investments

TK investment plays an important role in relation to an ISH’s involvement in the ownership structure of the GK project company. As the GK project company is held by an ISH that is independent of the project sponsors, certain arrangements for project sponsors to inject money into the project company and receive returns from the money so injected are required. TK investments are employed for that purpose as a substitute for legal equity in the GK.

A TK investment is an investment made pursuant to a TK contract, which is a bilateral contract whereby one party (TK Operator) receives funds from the other party (TK Investor) and, with those funds, conducts certain business as pre-agreed with the TK Investor, sharing the profit generated from such business with the TK Investor. The business is conducted in the name of the TK Operator, and the TK Investor’s liability is limited to the obligation to make an investment of a pre-agreed amount, which means that a TK investment is a limited liability investment.

The TK Operator may enter into a TK contract for the same business with multiple parties, in which case, taken as a whole, the structure will be economically very similar to a limited liability company where the TK Operator is the company and the TK Investors are members of the company. However, a key difference is that each TK contract needs to remain bilateral and no multilateral agreement involving two or more TK investors is used. Under a TK contract, the profit and loss allocated to TK Investors is directly recognised by the TK Investors, instead of the TK Operator. The effect of this allocation is that the project revenue is not subject to corporate tax at the project company level.

However, whether a TK investment can be used as equity in a particular project must be carefully examined. For example, in the case of PFI/PPP projects and offshore wind projects, both of which involve a public authority procurement process, the tender documents often require the equity investment to be made in the form of legal equity. Also, some financial institutions dislike TK investments in biomass projects.

Debt-to-Equity Ratio

Another characteristic of project finance in Japan is that a certain debt-to-equity ratio is often required to be maintained, not only during the construction period but also during the operation period. In such a case, project sponsors need to structure their financial model carefully so that this requirement does not affect the return on invested capital.

FIT Projects and CPPA

Since the introduction of the FIT in Japan in 2012, FIT projects have been predominant in the renewable energy project field, where certain utilities are legally obliged to purchase all electricity generated by approved power plants at a fixed price and for a fixed term. From April 2022, however, FIT approval ceased to be newly granted for the vast majority of renewable energy project categories, with feed-in premium (FIP) approvals starting to be granted instead. Under the FIP regime, on the one hand project companies can receive prescribed premiums from the government to supplement their revenue, but on the other hand project companies need to independently sell their generated electricity into the power market or to retailers by entering into a bilateral power purchase agreement (Corporate PPA).

Corporate PPA projects consist of “physical” and “virtual” (VPPA) projects. In “physical” Corporate PPA projects, electricity is physically supplied from the project company to the offtaker. In contrast, in VPPA projects, only non-fossil certificates are transferred directly from the project company to the offtaker, with the project company selling the physically generated electricity and the offtaker purchasing the electricity in the marketplace. The project company and the offtaker make a pre-agreed price settlement for the transaction as a whole to have the same economic effect as the sale and purchase of the electricity certified by the corresponding non-fossil certificate at a fixed price from the project company to the offtaker. Regardless of whether FIP is utilised, since the latter half of 2022, there have been many projects in Japan using Corporate PPAs and the project finance market is rapidly expanding in this field.

Offshore Wind Projects

Offshore wind projects have been attracting the attention of the market, in light of the Japanese government strongly promoting renewable energy as a means to achieve a carbon-neutral society by 2050, and because of the potentially numerous offshore wind opportunities provided by the island geography of Japan.

A legal impediment to offshore wind projects was that, unlike for harbour areas, for many years there was no legislation regulating the use of general sea areas. This issue was addressed by the Act on Promoting the Utilisation of Sea Areas for the Development of Marine Renewable Energy Power Generation Facilities (Act No 89 of 2018, as amended), which came into force in 2019. Under this Act, the government designates sea areas that it considers suitable for offshore wind projects and selects a project developer through a tender process, who is granted a right to use the designated sea area for up to 30 years.

In December 2021, the government announced the winning consortium in relation to three designated sea areas. As it was effectively the first tender process under this Act, the tenders captured the attention of the entire renewable energy industry but the market was shocked by the result: the same consortium won the tender for all three designated sea areas. Furthermore, the winning price was substantially lower than that of other competing consortiums. In response to this surprising result, the criteria for selecting project developers was revised to shift focus from the energy supply price to the achievability of the proposed energy supply plan and the time period required before commencement of the power source operation. Based on the new criteria, the government is now reviewing proposals for the second tender process for an additional four designated sea areas. In the coming years, similar tender processes are expected to be held for other sea areas that are currently undergoing feasibility studies by the government. As such, it is highly likely that offshore wind projects will continue to attract close attention from the market.

Energy Storage Projects

Energy storage projects have been generally recognised as having a disadvantage in attracting project financing because their future cash flow is not easily projected due to their revenue being exposed to fluctuations of the electricity market. However, under the Long-Term Carbon Neutrality Capacity Auction regime, project companies will be paid availability-based payments which will bring significant stability to their cash flow. Consequently, both sponsors and lenders are conducting feasibility studies into adopting project finance for energy storage projects utilising the Long-Term Carbon Neutralilty Capacity Auction regime.

Integrated Resorts

Integrated resorts (ie, a combination of facilities where a casino is the central and key component facility surrounded by other facilities such as hotels, amusement facilities and convention centres) are also attracting the attention of the market.

Under the Act on Development of Specified Complex Tourist Facilities Areas (Act No 80 of 2018), cities interested in developing an integrated resort are to select private sector partners (including casino operators) and submit a joint proposal to the national government. At the end of the process, the national government will select up to three winning proposals from all of the joint proposals submitted. Only one municipality was selected in 2023, which was Osaka Prefecture/Osaka City. Nagasaki Prefecture, which had also submitted a proposal to the national government within the 2022 deadline, is still undergoing the review process and is yet to receive confirmation of selection. Financial institutions are exploring ways of providing finance for construction costs by way of project-based finance.

Under Japanese law, the principle is that any property having economic value can be taken as security, unless creating a security interest in such property is prohibited by law. There are three forms of security interest that can be created by contract under Japanese law:

  • mortgage (teitoken);
  • pledge (shichiken); and
  • collateral assignment (joto tampo).

A mortgage and a pledge are both security interests established by legislation, while a collateral assignment is a security interest developed through case law.

Mortgages (Teitoken)

A mortgage is available for real estate, automobiles, vessels, aircraft and some other assets. The Japanese government has established and administers a title registration system for each such asset, and perfection of title is made through registering the title in the government-operated title registration system. Mortgages are also perfected through the title registration system.

There are also special types of mortgage:

  • a factory mortgage (kojo teito) for mortgages over factories; and
  • a factory foundation mortgage (kojo zaidan teito), which is for mortgages over the foundation that owns a factory (kojo zaidan).

Where a factory mortgage is created over the site of a factory, the security interest extends to the equipment and facilities used for the factory on that site, provided that such equipment and facilities are registered as components of that factory under the title registration system. Where a factory foundation mortgage is created over a factory foundation, the security interest extends to property that is listed as property of that factory foundation. A factory foundation whose primary property is the site of the factory, the structures erected on the site and the equipment and facilities used for the factory is also permitted to own certain intangible property, such as the leasehold of the site and intellectual property related to that factory, in which case the factory foundation mortgage will cover such intangible property as well. In the context of factory mortgages and factory foundation mortgages, a power plant is considered to be a “factory”.

Furthermore, in relation to a PFI project, mortgages can be created over Concession Interests (kokyoshisetsuto uneiken) (ie, specified rights and interests in the infrastructure assets that are granted to a concessionaire in relation to a concession scheme project under the PFI Act). However, since any transfer of Concession Interests is subject to the consent of the grantor of the Concession Interests, unlike other mortgages, enforcing a mortgage over Concession Interests requires the consent of the grantor of the Concession Interests.

Pledges (Shichiken)

A pledge is available for any property. However, as far as project finance is concerned, pledges are not typically used for real estate or other tangible property (ie, movable property), and are only used for intangible property such as receivables, bank accounts, insurance proceeds, shares in a company or other forms of equity interests, copyrights and patents, etc. The most relevant reason for only using pledges for intangible property in project finance is that if a pledge is created over real estate or movable property, the owner of the real estate or movable property is deprived of the right to occupy, hold and use such property, which means that the project company cannot occupy, hold or use its real estate or personal property if a pledge is created over such property.

The way to perfect a pledge varies, depending on the type of property over which the pledge is created. A pledge created over a receivable is perfected upon:

  • written acknowledgement of the pledge by the debtor of the receivable with a date-certifying stamp of a notary public; or
  • written notice from the pledgor of the pledge to the debtor with a date-certifying mail.

The same methods of perfection apply to pledges over bank accounts and over insurance proceeds, because a bank account is considered as a depositor’s receivable against the bank and a claim for insurance proceeds against an insurance company is also considered as a receivable against the insurance company. Registering the pledge under the receivable registration system administered by the Ministry of Justice is an alternative means of perfecting a pledge created over receivables. This saves a great deal of cost and time compared to obtaining written acknowledgement from each debtor of those receivables or sending written notice to each debtor.

Other pledges are perfected as follows:

  • a pledge created over a share in a kabushiki kaisha corporate entity that issues share certificates is perfected upon delivery of the share certificate representing such share;
  • a pledge created over a share in a kabushiki kaisha corporate entity that does not issue share certificates is perfected upon recording the pledge in the shareholder ledger of that company;
  • a pledge created over a share in a listed company is perfected upon recording the pledge in the share transfer recording system administered by the Japan Securities Depository Centre, Incorporated (JASDEC);
  • a pledge created over intellectual property is perfected upon registration of the pledge under the registration system administered by the Japan Patent Office; and
  • a pledge created over a membership interest in a godo kaisha corporate entity is considered to be perfected in the same manner as a pledge over receivables and, in practice, is perfected by obtaining the company’s (ie, the godo kaisha’s) written acknowledgment accompanied by a date-certifying stamp of a notary public.

Collateral (Joto Tampo)

Collateral assignment is available for any property, but in the field of project finance it is usually used for tangible property other than real estate (ie, movable property), and sometimes for receivables. Collateral assignment is often used to complement pledges, as collateral assignment does not deprive the owner of the property of the right to hold and use it. Collateral assignment of movable property is perfected upon the owner of that movable property acknowledging the assignment. The owner is permitted to continue to hold and use the movable property as it did before the collateral assignment was made. Collateral assignment of receivables is perfected in the same manner as a pledge. Collateral assignment of movable property and receivables can also be perfected by registering the collateral assignment under the registration system administered by the Ministry of Justice.

In addition to the above forms of security interests, as a substitute for taking a contract as security, a call option may be granted by a project company to project finance lenders with respect to the contractual position that the project company holds under a contract. Just as with other security interests, the option is structured to become exercisable upon the occurrence of an event of default or acceleration of debt and, if the option is exercised, the project company must transfer its contractual position under that contract to any person that is designated by the lenders (including themselves). Such arrangement is referred to as a “grant of call option (joto yoyaku) with respect to contractual position (keiyakujonochii)”. It is not a security in a legal sense, but it is used to secure project finance lenders’ so-called “step-in right” to project agreements.

Japanese law does not recognise floating charges or any other universal or similar security interest over all present and future assets of a company. However, the Financial Services Agency of Japan has initiated a movement towards legislating a so-called “business growth security” (jigyo seicho tampo), the general aim of which is to enable a company to provide security over its business as a whole. It is expected that such a “business growth security” could be utilised for project finance. Preparations for the introduction of legislation to establish such “business growth security” rights have been accelerated since the publication of the report issued by the governmental working group for such “business growth security” rights in February 2023.

Registration tax (torokumenkyo zei) is imposed on the registration of the creation of a security interest. In the case of a mortgage over real estate, the rate is 0.4% of the registered face value of the secured obligations, and 0.25% in the case of a factory mortgage or factory foundation mortgage. Temporary registration (kari toki) of a mortgage is sometimes allowed by lenders up to the occurrence of a specified credit event. This has the legal effect of maintaining the priority order of the mortgage, although the temporary registration must subsequently be changed to definitive registration (hon toki) to implement in-court foreclosure under the mortgage. The registration tax levied on temporary registration is JPY1,000 per registration.

In the case of a pledge or collateral assignment, the registration tax is JPY7,500 per registration.

Each property on which a mortgage is created must be individually identified in the security document, as registration is made on each property.

With respect to movable property and receivables subject to collateral assignment, each item of collateral does not need to be individually identified in the security document to grant a valid security interest in that item. A general description of the types of collateral covered would be sufficient, as long as such description can distinguish the assets of the security provider that are subject to the security interest from those that are not.

Under Japanese law, the proceeds of third-party liability insurance cannot be taken as security.

Distinctions Between Security/Guarantee Categories

Under Japanese law, each of the above-mentioned three forms of security interest –mortgage (teitoken), pledge (shichiken) and collateral assignment (joto tampo) (see 2.1 Assets Available as Collateral to Lenders) – and guarantees are classified into one of two types:

  • ordinary security/guarantee (futsu tampo/hosho), used to secure identified specific obligations (eg, term loans); or
  • revolving security/guarantee (ne tampo/hosho), used to secure unidentified obligations that arise out of a certain specific type of transaction or a certain specific contract (revolving loans, claims under hedging agreements, etc).

Once the obligations secured by a revolving security/guarantee are fixed (ie, crystallised), the revolving security/guarantee gains substantially the same characteristics as an ordinary security/guarantee.

Revolving Securities/Guarantees and Mortgages

Revolving securities/guarantees were invented and developed through practice and later ratified by case law. While a revolving mortgage (ne teitoken) was codified thereafter, revolving pledges (ne shichiken) and revolving collateral assignments (ne joto tampo) have not been codified. Practitioners employ a revolving pledge and revolving collateral assignment with the understanding that the provisions of a revolving mortgage should apply to a revolving pledge and revolving collateral assignment; however, such practice has not been fully tested by the Japanese courts with respect to all of these aspects of a revolving mortgage.

There is another issue related to revolving mortgages. As is the case with an ordinary mortgage (futsu teitoken), the value of the obligations secured by a revolving mortgage must be registered. However, it may not be easy to estimate the maximum exposure a hedging provider may have during a project. At the same time, the rate of registration tax (torokumenkyo zei) depends on such amount. Therefore, the value of the obligations secured as registered must be agreed between the project finance lenders and project sponsors prior to registration.

There are a number of types of statutory liens under Japanese law. Some are attached to an employee’s salary claims, certain construction fees, receivables of sellers of goods, funeral costs, etc. Certain statutory liens have to be registered under the title registration system to secure their priority, so lenders can confirm whether those statutory liens exist by checking the title registration records. For other statutory liens, lenders have no means to confirm whether they exist, other than by checking with the potential parties to such lien.

Generally, security interests automatically cease to have an effect upon the secured obligations being discharged in full, but it is common practice for the lender to deliver a release letter confirming that the security interest no longer exists. Such release letter is more important if the security interest is a revolving security interest/guarantee because the revolving security interest/guarantee is not necessarily extinguished when the outstanding secured obligations are discharged in full.

Under Japanese law, a secured lender can enforce its collateral when the debt secured by such collateral is not paid on the day when it becomes due and payable. Under a financing agreement, the parties agree to a set of events or circumstances that would make outstanding loans immediately due and payable. This is called an “event of default” or “event of acceleration” (kigennorieki soshitsujiyu). Some of these events or circumstances automatically accelerate repayment of the loans, while others only accelerate repayment of the loans if the lender so notifies the borrower.

Under Japanese law, there are two means to enforce a security interest: in-court foreclosure and out-of-court foreclosure. However, in-court foreclosure is not available for collateral assignment; out-of-court foreclosure is the only way to enforce a collateral assignment.

In order to enforce a right, in general, the holder of the right must obtain a court judgment (or arbitration award if arbitration is the agreed method of dispute resolution) and then present it to the court for execution. However, in the case of enforcing security, the secured interest holder only has to prove the existence of the security by way of presenting an executed security agreement and/or the relevant perfection documents to the court. The secured interest holder does not have to obtain a judgment that the debt secured is due and payable, and not yet discharged.

Once the existence of the security interest is proved, it is the debtor that owes the burden of proof to show that the debt is not due or otherwise is not required to be paid. When the application for enforcement of a security interest is filed with the court, the court will usually hold a public auction in which the collateral will be sold to the highest bidder and the security interest holder will receive the net proceeds from the sale of the collateral.

Security interests can be enforced outside a court, provided that the process of so enforcing the secured interests is agreed and set out in a security agreement. It is standard practice in a Japanese financing transaction to set out the following in a security agreement:

  • the right of a secured party to dispose of secured property and apply the proceeds to the secured claim; and
  • the right to appropriate the secured property at its appraised value.

It is generally considered that secured interests can be more quickly enforced and greater value realised from the enforcement if the enforcement is conducted out of court rather than through an in-court foreclosure proceeding. For mortgages, out-of-court foreclosure requires the further co-operation of the mortgagor in that the mortgagor must become the seller of the mortgaged property. In contrast, in the case of pledges, the secured party can directly exercise its pledge rights and can obtain the title to (and sell) any pledged asset if so agreed with the pledgor in the pledge agreement, in each case, without the involvement of the pledgor. This is the same in the case of collateral assignments. For a collateral assignment, the secured party can obtain the title to (and sell) the assigned property by following the procedures stipulated in the security agreement without further co-operation of the assignor.

The Act on General Rules for Application of Laws (Act No 78 of 2006, as amended) controls conflict of laws issues in Japan, and allows parties to a contract to choose the jurisdiction governing the contract. Accordingly, the courts of Japan generally uphold the choice of foreign law provision in a contract. However, under this Act, if it finds that the application of a foreign law chosen by agreement between the parties to a contract would lead to a consequence that is detrimental to the public order of Japan, the court will refuse to apply the chosen foreign law and apply Japanese law instead. Furthermore, Japanese laws and regulations covering certain areas – eg, antitrust, foreign exchange, labour, usury and real estate lease – are considered mandatory, and will therefore apply regardless of any choice of foreign law.

The Code of Civil Procedure (Act No 109, 1996, as amended) provides that the parties may choose a court in a foreign country as the agreed venue of dispute resolution. Accordingly, the courts of Japan generally recognise a choice of foreign court made in a contract. However, the Code of Civil Procedure also provides that a choice of foreign court will not be upheld if the Japanese court decides that such court in a foreign country does not have the capability (legally or otherwise) to exercise the jurisdiction of that foreign court.

As Japan is a member state of the New York Convention, an arbitral award would be recognised by the courts of Japan and may be enforced without retrial of the merit, in accordance with, and subject to, the New York Convention and the Arbitration Act (Act No 138 of 2003, as amended).

A final judgment rendered by a foreign court would be recognised, and may be enforced without retrial of the merit if it satisfies a certain set of requirements set out in Article 118 of the Code of Civil Procedure. Such requirements include that reciprocity between the country of the relevant judgment and Japan is assured, and that the terms of the judgment and the judicial procedure through which the judgment was rendered do not conflict with the public order and morality of Japan.

In a judicial proceeding in Japan, Japanese citizens and foreigners are treated equally, and there are no substantive restrictions on a foreign lender’s ability to enforce its rights under a loan or security agreement. However, as the official language in Japanese courts is Japanese, a foreign lender would have to prepare a Japanese translation of the documents produced by its home country’s government – eg, certificate of incorporation – to establish its identity. All other documents to be filed with the Japanese court must also be in Japanese or be accompanied by a Japanese translation.

Furthermore, where a foreign lender who does not have any presence in Japan files a claim with a Japanese court, the Japanese court would likely order the foreign lender to place a security deposit with the court to cover the costs and expenses that may be incurred by the court in relation to a trial of such claim.

A foreign lender must have a money-lending licence under the Money Lending Business Act (Act No 32 of 1983, as amended) in order to engage in the business of granting loans or money-lending in Japan, except where a foreign bank grants a loan through its licensed branches in Japan.

Whether granting a loan is conducted as business for the purpose of this Act is a fact-oriented issue. Thus, care must be taken if a project sponsor seeks to inject equity into the project company by way of extending a subordinated loan, as it is often considered that a person who extends a loan more than once is deemed to engage in money-lending business for the purpose of this Act.

Under the Money Lending Business Act, engaging in only intra-group lending that satisfies certain prescribed criteria is exempted from the licence requirement. This includes lending to and from a subsidiary in which a lender has 50% or more of the shares, or 40–50% of the shares with supporting factors indicating control over such subsidiary, such as the lending company dispatching officers to work in the subsidiary.

Loans to a joint venture (JV) company by a JV partner are also exempted if the lending JV partner holds 20% or more of the JV company’s shares and all the other JV partners consent to the granting of such loans. If the project sponsor’s relationship with the borrowing company does not fulfil these exempting requirements, such as where the lending company holds less than 20% of the shares in the borrowing company, under the above prevailing view on what constitutes money-lending business, such project sponsor effectively cannot use subordinated loans as a means of injecting equity. In such a case, bonds (shasai) with a subordination clause would typically be employed as a substitute for subordinated loans, as subscribing for a bond is not considered to be money-lending for the purpose of this Act.

In general, there are no restrictions on the granting of security or guarantees to foreign lenders, and foreign lenders may also take security or guarantees in the same manner as Japanese lenders do.

The foreign investment regime under the Foreign Exchange and Foreign Trade Act (Act No 228 of 1949, as amended) was reformed to further promote sound investment into Japan and to appropriately monitor investment into Japan that may undermine national security. The new rules have been in effect since June 2020.

In general, the following foreigners are only required to file ex post facto notification to the Bank of Japan, unless the subject company conducts business in a “Designated Industry”:

  • those who have acquired a share in an unlisted company or 1% of shares in a listed company; or
  • those who have provided finance of JPY100 million or more by way of extending a loan or subscribing for a bond with a term of one year or more to a company that has resulted in 50% or more of such company’s outstanding debt with a term of one year or more being owed to such investors.

The “Designated Industry” classification is divided into “Core Industries” and “Non-core Industries”. In general, a Core Industry is an industry that is closely connected to national security and/or fundamental infrastructure such as manufacturing firearms, lithium ion batteries, aircraft or spacecraft, or that is related to electricity, telecommunications, oil or gas, while a Non-core Industry is an industry other than a Core Industry that is still considered to be important from a national security perspective and/or fundamental infrastructure, such as broadcasting, or is related to biological products, or marine or air transportation.

Where the subject company conducts business in a Designated Industry, the foreign investor may not make the investment unless the foreign investor makes a prior notification and the specified waiting period expires; such period is generally 30 days. This period could be shortened to five business days if the government considers that the waiting period can be so shortened from a national security perspective, but may also be extended up to five months, at the discretion of the government.

If the government determines during the waiting period that the investment may undermine national security, public order or public safety, or adversely affect the national economy, it may issue a warning to change the terms of the investment, or cancel it. If the investor does not respond to the warning or expresses an intention to disobey the warning, the government may issue an order to change the terms of the investment, or cancel it. Enforcement by a foreign lender of its security interests over any shares in a Japanese company that conducts business in a Designated Industry may also be restricted by such regulations.

On the other hand, the new rules have introduced an exemption from the above prior notification requirement.

First, certain financial institutions (eg, banks, security brokers, insurance companies and fund managers) that are adequately regulated in their home countries are fully exempted from the prior notification requirement.

Second, foreign investors that are not a foreign state or a state-owned enterprise (excluding sovereign wealth funds and public pension funds certified by the Ministry of Finance of Japan) and do not have a criminal record are exempted from the prior notification requirement in the following circumstances.

  • In the case of investment in a company that conducts business in a Non-core Industry:
    1. those foreign investors and their related persons will not assume the office of director or internal surveillance officer (kansayaku) of the company to be invested in and its affiliates;
    2. those foreign investors, as shareholders of the company to be invested in, will not propose or cause to be proposed any disposition or abolishment of the business conducted by the company to be invested in at any shareholder meeting of the investor company; and
    3. those foreign investors will not access sensitive technology information held by the company to be invested in.
  • In the case of investment in a company that conducts business in a Core Industry:
    1. those foreign investors do not acquire 10% or more of the total voting rights of the company to be invested in;
    2. those foreign investors will not participate in any board of directors meetings or any other high-level decision-making body of the company to be invested regarding Core Industry business;
    3. those foreign investors will not submit a written proposal to the board of directors or any other high-level decision-making body of the company to be invested in setting a deadline for their response or reaction regarding Core Industry business; and
    4. those foreign investors satisfy the above three requirements that apply to investment in a company that conducts business in a Non-core Industry.

Nationality Requirement

Furthermore, companies in certain regulated industries are subject to a nationality requirement under the respective industry regulations. In this case, generally, a prescribed shareholding majority of such companies must be owned by Japanese citizens and/or Japanese corporations, and this requirement must be fulfilled in order to obtain and maintain a licence for such company to conduct its business. Examples of such companies are a broadcasting company under the Broadcasting Act (Act No 132 of 1950, as amended) and an airline company under the Aviation Act (Act No 231 of 1952, as amended). If a foreign lender places security interests over shares in such a company, the foreign lender may only enforce the security interests by way of selling such shares to Japanese citizens or Japanese corporations.

Under the Foreign Exchange and Foreign Trade Act, ex post facto notification to the Bank of Japan is usually required for a cross-border payment of more than JPY30 million, unless such payment is made in connection with the international trade of goods.

Under the Income Tax Act (Act No 33 of 1965, as amended), dividends, interest and profit distribution to a TK investor are subject to withholding tax of 20.42% where the recipient is non-resident. Such withholding tax may be reduced or exempt if Japan has a tax treaty with the country where the foreign recipient is resident and such recipient satisfies the applicable conditions to enjoy treaty benefits.

A project company is permitted to maintain offshore foreign currency accounts.

None of the financing or project agreements need to be registered or filed with any government authority nor otherwise need to comply with any local formalities in order to be valid or enforceable, except that certain security interests have to be registered in order to be perfected (such registration would require the disclosure of the basic terms of the obligations secured by the security – eg, amount and interest rate).

In general, no licence is required to own land in Japan. This also applies to foreign entities, unless a foreign entity engages in the real estate brokerage business.

Minerals or other natural resources, such as natural gas and crude oil, may not be extracted without a licence, under the Mining Act (Act No 289 of 1950, as amended), and such licences are not granted to non-Japanese persons or corporations.

The concepts of agency and trust are both recognised in Japan. In particular, the Trust Act (Act No 108 of 2006, as amended) clarifies that creating a security trust is permissible. However, due to some practical reasons, security trusts are not commonly used in project finance or any other syndicated lending transactions in Japan. As such, security is granted to each of the lenders individually, and each time a lender disposes of its shares in a syndicated facility, a new lender has to perfect the acquisition of certain security interests and guarantees. In relation to this, an ordinary security interest/guarantee is tagged with – and carries the loans secured by – such ordinary security interest/guarantee by operation of law. On the other hand, a revolving security interest/guarantee does not transfer along with the obligations secured by that revolving security interest/guarantee until it is crystallised.

Where security interests compete with each other, priority will be determined based on when the security interest is perfected: the security interest that is perfected earlier will have priority over that which is perfected later.

In order to agree on the priority of enforcement proceeds, secured lenders typically enter into an intercreditor agreement. However, a Japanese court would not uphold such intercreditor agreement in a foreclosure proceeding and would distribute enforcement proceeds to secured lenders in priority of the time that the security interests were perfected and in accordance with the relevant statutes that determine the priority between the security interests and any other statutory liens. After the distribution of such proceeds is made by the court, the secured creditors who received such proceeds and are parties to the intercreditor agreement are obliged by contract to redistribute such proceeds so that the secured creditors will receive the enforcement proceeds as contemplated by the intercreditor agreement.

Japanese law does not require a project company to be incorporated under the laws of Japan. However, in its request for proposals for PFI/PPP projects, in practice the procuring authority always requires that the project company be a corporation incorporated under the laws of Japan, usually a kabushiki kaisha. As a matter of practice, it is extremely rare for a project company to be a foreign law corporation; the typical form of a project company is a kabushiki kaisha or a godo kaisha.

Under Japanese law, there are four types of insolvency proceedings:

  • bankruptcy proceedings (hasan tetsuzuki);
  • special liquidation proceedings (tokubetsu seisan tetsuzuki);
  • civil rehabilitation proceedings (minji saisei tetsuzuki); and
  • corporate reorganisation proceedings (kaisha kosei tetsuzuki).

Of these four types of insolvency proceedings, civil rehabilitation proceedings and corporate reorganisation proceedings are reorganisation-type procedures; the other two are liquidation-type proceedings. Special liquidation proceedings and corporate reorganisation proceedings are only available to a kabushiki kaisha.

Civil rehabilitation proceedings are often referred to as debtor-in-possession (DIP) proceedings, as the debtor’s management continues to operate the debtor’s business while being overseen by a supervisor (kantoku iin) appointed by the court.

Corporate reorganisation proceedings are a reorganisation-type procedure where a reorganisation trustee (kosei kanzainin) appointed by the court operates and protects the debtor’s business and property.

When insolvency proceedings commence with respect to a debtor, in general, creditors of that debtor may not enforce their rights outside those proceedings. In liquidation-type proceedings, the creditors will only receive distributions from the proceeds of disposition of the debtor’s assets. In reorganisation-type proceedings, creditors have the right to vote on any proposed rehabilitation/reorganisation plan, and, subject to any write-offs or rescheduling of their claims under the rehabilitation/reorganisation plan that is approved, their claims will be paid in accordance with the approved rehabilitation/reorganisation plan.

However, the commencement of any insolvency proceedings other than corporate reorganisation proceedings does not prevent secured creditors from enforcing their security outside the insolvency proceedings and recovering their loans from the enforcement proceeds of the collateral. In contrast, under corporate reorganisation proceedings, secured creditors are not allowed to enforce their security. Project finance lenders preferring bankruptcy remoteness therefore require the project company to be a godo kaisha, as corporate reorganisation proceedings are only available against a kabushiki kaisha.

In insolvency proceedings other than corporate reorganisation proceedings (ie, civil rehabilitation proceedings, bankruptcy proceedings or special liquidation proceedings), secured creditors may recover their outstanding loans from the enforcement proceeds of the collaterals, or from the debtor’s general assets to the extent that those secured creditors cannot fully recover their loans from the enforcement proceeds of the collaterals. Proceeds from the disposition of the debtor’s general assets are distributed to creditors on a pro rata basis. In a corporate reorganisation proceeding, all the creditors, including secured creditors, will recover their outstanding loans in accordance with the approved reorganisation plan.

Debts under certain subordination agreements are treated as subordinated under the respective insolvency proceedings. Where a sponsor injects equity by way of subordinated debt or TK investment, project finance lenders usually ensure that the subordinated debt or TK investment agreement contains the specific type of clause required for the injected equity to be treated as such.

A debtor that has become insolvent is unlikely to have sufficient assets to discharge all of its outstanding debts, in which case creditors that do not have sufficient security would typically end up writing off their loans. Those creditors may try to obtain some of the debtor’s assets as security to secure their priority on those assets, but such action is capable of being avoided under any subsequent insolvency proceedings as being an impermissible preference.

Corporate reorganisation proceedings are generally considered unfavourable to secured creditors in that the secured creditors are not allowed to enforce their collateral until the approved reorganisation plan is fully implemented, and the reorganisation plan may write off their loans and/or reschedule the repayment of their loans.

No private entities are excluded from insolvency proceedings in Japan, although special liquidation proceedings and corporate reorganisation proceedings are only available to the kabushiki kaisha company form. However, governments and local municipalities are considered to be excluded from insolvency proceedings.

In general, foreign insurance companies are not allowed to provide insurance to Japanese residents for property located in Japan or vessels or aircrafts registered in Japan unless they open a branch office in Japan and obtain a licence under the Insurance Business Act (Act No 105 of 1995, as amended), with the following exceptions:

  • reinsurance;
  • marine insurance;
  • aircraft insurance;
  • spacecraft insurance;
  • international cargo insurance; and
  • overseas travel insurance.

There are no restrictions on foreign creditors receiving proceeds from insurance policies over project assets.

Under the Income Tax Act, interest payable to a foreign lender is subject to withholding tax of 20.42%. Such withholding tax may be reduced or exempt if Japan has a tax treaty with the country where such lender is resident and such lender satisfies the applicable conditions to enjoy treaty benefits. Please also see 4.4 Restrictions on Payments Abroad or Repatriation of Capital regarding withholding tax on dividends and profit distribution to a TK investor.

Under the Stamp Duty Act (Act No 23 of 1967, as amended), a loan agreement is subject to stamp duty, the amount of which varies depending on the amount of the loan evidenced by the loan agreement. The stamp duty will be JPY600,000 if the amount of the loan is more than JPY500 million. However, stamp duty is not applicable to a loan agreement if all parties to the agreement execute it solely electronically.

The Interest Restriction Act (Act No 100 of 1954, as amended) is the main source of usury laws in Japan, and restricts the amount of interest that can be charged. Under this Act, for a loan of JPY1 million or more, interest at a rate of more than 15% per year and default interest at a rate of more than 21.9% per year may not be charged. For the purposes of this Act, any amount that in substance is charged like interest is deemed to be interest, no matter how the amount may be described. Furthermore, this Act states that any commitment fee to be charged on a revolving credit facility will fall within the definition of interest. This created difficulties in the corporate finance sector and was therefore specifically addressed by the enactment of the Act on Specified Credit Commitment Contracts (Act No 4 of 1999, as amended), under which a commitment fee is deemed not to fall within the definition of interest for the purposes of the Interest Restriction Act if the relevant revolving credit is granted to an entity that satisfies certain requirements – eg, the entity is a kabushiki kaisha with stated capital of JPY300 million or more, or with a net worth of JPY1 billion or more.

However, in practice, since a project company is sometimes so thinly capitalised that it may not satisfy these requirements under the Act on Specified Credit Commitment Contract, to avoid violating the Interest Restriction Act it is relatively common for a commitment fee not to be charged to a project company in respect of the availability of any project finance facility at all, or until a first drawdown is made.

For tax purposes, Japan has both thin-capitalisation rules and earning stripping rules. Thin-capitalisation rules are applicable to interest that is:

  • paid by a domestic entity to its foreign controlling shareholders and certain third parties (eg, third-party lenders who receive financing or guarantees from the foreign controlling shareholders of the borrowing domestic entity); and
  • not subject to Japanese taxation at the level of the recipients of the interest payments.

The prescribed portion of such interest is not deductible in calculating taxable income of the payor if both the following conditions are met:

  • the amount of total debts (whether interest-bearing or not) owed by the payor exceeds three times the amount of capital of the payor; and
  • the amount of total debts (whether interest-bearing or not) owed by the payor to its foreign controlling shareholders and such third parties (as referred to in the first bullet point above) exceeds three times the amount of capital of the payor multiplied by the ownership percentage of the foreign controlling shareholders.

Under the earning-stripping rules, interest is not deductible in calculating the taxable income of the payor, if and to the extent that the total amount of interest that is paid to (both related and third-party) lenders and not subject to Japanese taxation at the level of the recipients of the interest payments exceeds 20% of EBITDA of the payor as calculated for this purpose.

Project agreements are typically governed by Japanese law. A PFI/PPP agreement or concession agreement with the Japanese government, a local municipality or a state-owned entity is always governed by Japanese law. However, fuel supply agreements with a foreign supplier in power projects (eg, conventional power projects and biomass projects) are sometimes governed by foreign law, such as English law or New York law.

Financing agreements are always governed by Japanese law, with the exception that security agreements on collaterals located outside Japan would typically be governed by the laws of the jurisdiction where those collaterals are located.

As described in 9.1 Project Agreements and 9.2 Financing Agreements, project agreements and financing agreements are governed by Japanese law, with only a few exceptions.

Renewable Energy

Overall trends

Project finance in Japan continues to involve a large number of financing transactions for renewable energy, such as photovoltaic and wind power. Since the introduction of the Feed-in Tariff (FIT) system in 2012, most of the renewable energy projects eligible for project finance utilised the FIT system. However, the amended act, effective as of 1 April 2022, has been facilitating the transition from the FIT system to the Feed-in Premium (FIP) system, and there are increasing situations where financing is being arranged for projects subject to the FIP system or that do not rely on either the FIT or the FIP system. In addition, suitable areas for large-scale renewable energy power plants are decreasing in Japan, and with an increasing trend of small-scale new developments, there is also an increase in the number of transactions seeking to obtain project financing by combining multiple small-scale power plants.

Unlike the FIT system, the FIP system is based on the premise that renewable energy power producers earn revenue from electricity sales through normal market transactions with electricity retailers (either transactions in the wholesale electricity market or over-the-counter transactions), and FIP-certified renewable energy power generation projects will receive, in addition to revenue from market transactions, a premium calculated by a certain method through the Organization for Cross-regional Coordination of Transmission Operators (OCCTO). That is, unlike the FIT system, the FIP system does not guarantee purchase at a fixed price, and therefore, in considering project financing, it is necessary to take into account how cash flows for a particular project are stabilised. As a result, an increasing number of projects are engaging in corporate Power Purchase Agreements (PPAs), in which power is sold at a fixed price for a long period of time through an agreement with a customer company.

Corporate PPAs

With the increase in the number of projects not relying on purchase at a fixed price under the FIT system, there has been an increase in the number of corporate PPAs, in which power producers enter into a contract with a customer company to sell electricity. There are several transaction types for corporate PPAs, and the three main arrangements found in Japan are as follows.

  • Onsite PPA – a method in which a power generation facility is installed at a customer company’s site of demand and electricity is supplied to buildings and other facilities within that site. In this case, under the Electricity Business Act, there is no need to use an electricity retailer as an intermediary which is registered under that Act, and a PPA can be concluded directly between the power producer and the customer company.
  • Physical PPA (Offsite PPA) – a method in which electricity generated by a power generation facility located outside a customer company’s demand site is supplied to the customer company via the grid of a general electricity transmission and distribution utility. When concluding a physical PPA contract with a customer company, under the Electricity Business Act, power producers are required to use an electricity retailer as an intermediary which is registered under that Act.
  • Virtual PPA – a method in which the difference between a quoted price in the electricity market and an agreed price in the PPA is settled based on the amount of electricity and no physical delivery of electricity is made. For virtual PPAs, a direct over-the-counter transaction between power producers and customers has been established for non-FIT non-fossil certificates, which were previously only available to electricity retailers. Accordingly, customer companies can now purchase non-FIT non-fossil certificates directly from power producers, enabling transactions to be conducted under a simpler plan than before. In addition, as virtual PPA transactions typically settle by difference using electricity market prices and this settlement process has been subject to the Commodity Derivatives Transaction Act, it has been pointed out that, in principle, permission from the Minister of Economy, Trade and Industry may be required to engage in such transactions as a business. In this regard, however, the regulator expressed its views that if certain requirements are fulfilled and the transaction, as a whole, may be considered as a sale and purchase of Renewable Energy Certificates, etc, then the Commodity Derivatives Transaction Act does not apply to the transaction. This regulatory development has contributed to encourage greater use of virtual PPAs.

Onsite PPAs are relatively common due to their cost advantages and the fact that they do not require an electricity retailer as an intermediary. However, the number of projects that utilise a virtual PPA is rapidly increasing, in particular because policies have been established to encourage its introduction, as described above.

Further, the offtaker in projects under the FIT system is a major electric power company with high financial credibility and the possibility of early termination was considered to be low, whereas in non-FIT projects various customer companies are the offtakers and, depending on the contract terms, there may be greater chance of early termination. This change in potential termination risk requires a different analysis from that previously made under the FIT system.

Revision of FIT/FIP system

In recent years, there have been growing concerns regarding protection of local safety, security, landscape and environment as a result of certain instances of inappropriate development and construction of renewable energy power plants that have destroyed forests and harmed mountains. In order to address these concerns and accelerate the introduction of renewable energy in harmony with local communities, the government amended the laws, regulations and schemes related to the FIT/FIP system. Specifically, the following amendments were made. In particular, the amendments at the second and fourth bullet points will have an impact on business operators seeking FIT/FIP certification, as they will be required to take additional measures and may be forced to revise their existing business schedules.

  • To introduce measures to temporarily suspend the support under the FIT/FIP system provided to business operators which are violating the relevant laws and regulations – A FIT/FIP certified business operator is required to implement its power generation business in accordance with the certified plan, but, if it fails to comply with such certified plan, it will be subject to guidance and an improvement order, and eventually, in the case of continued non-compliance, its certification will be revoked. Under the previous system, however, the support under the FIT/FIP system (subsidies) would continue even while violations continued, and, consequently, there was concern that it would be difficult to resolve violations promptly. In order to address this concern, a new system will be introduced in which FIT/FIP subsidies will be withheld during the period of non-compliance with the certified plan.
  • To add, as a certification requirement, measures to require the provision of information about a project, such as holding a session for residents living in the vicinity of the installation site – The purpose of this amendment is to promote understanding of the renewable energy power generation business and foster trust in such business by providing appropriate information to residents in surrounding areas of a project. This provision of information is designed to address local concerns about the potential impact of a renewable energy power generation business on the community, and thereby encourage the introduction of a new renewable energy project in harmony with the local community. Thus, this amendment mandates the holding of explanatory meetings, among other things, with residents living in the vicinity of the installation site of power generation facilities.
  • To clarify the supervisory obligations of a certified business operator with respect to its contractors – Under the current system, the entity subject to business discipline is the certified business operator. However, a certified business operator’s liability is not clear in the event that a contractor or subcontractor fails to comply with the certified plan or violates certification criteria. For this reason, the new system legally clarifies the obligation of certified business operators to comply with the certified plan, and imposes on certified business operators the obligation to supervise their contractors and subcontractors to ensure that they also comply with the certification criteria and the certified plan.
  • To add, as an application requirement for certification, a permission for the development of forest areas under the Forest Act and a permission under the Act on Regulation of Residential Land Development and Specific Embankment – Under the previous system, it was considered sufficient to obtain these permissions after obtaining FIT/FIP certification. However, as these permissions for land development, in particular, importantly involve the safety of the surrounding area, and land is extremely difficult to restore to its original state once business activities subject to the permissions have been carried out, this amendment requires business operators to obtain necessary permissions prior to obtaining FIT/FIP certification.

Offshore wind power generation

In December 2021, a consortium representing the same group companies won a bid for offshore wind power generation in all three sea areas “off the coast of Noshiro City, Mitane Town and Oga City, Akita Prefecture”, “off the coast of Yurihonjo City, Akita Prefecture” and “off the coast of Choshi City, Chiba Prefecture”, which is referred to as the first round. As a result, the selection criteria for the operator in offshore wind power bidding were reviewed until December 2022 and, based on the results of the first round, the following revisions have been made.

  • Revisions to scoring for project feasibility evaluation– In the first round of bidding, the evaluation of the supply price was revised so that the bidder offering the lowest price received a full score (120 points), whereas the score for project feasibility evaluation was the sum of the points in each evaluation item out of a maximum of 120 points. After the change, the bidder with the highest evaluation score for each promotion zone will receive a full score of 120 points. For the evaluation of the supply price, all bidders that offer a price below a certain amount will also receive that full score assessment.
  • Changes in allocation of points for project feasibility evaluation; introduction of speed evaluation – The evaluation items for project feasibility were changed and, in particular, a high score of 20 points has been allocated to “speedy project planning” as an independent evaluation item.
  • Introduction of bidding restrictions – If the same bidder ranked first in evaluation points for multiple promotion zones where both the total grid capacity and the total capacity of installed power generation facility exceeded 1 GW, bidding restrictions will be applied.

As mentioned above, with the completion of the review of the selection criteria in the bidding process, the bids have been resumed for offshore wind power generation. Currently, the public tender process is underway for four sea areas “off the coast of Happo Town and Noshiro City, Akita Prefecture”, “off the coast of Oga City, Katagami City and Akita City, Akita Prefecture”, “off the coast of Murakami City and Tainai City, Niigata Prefecture” and “off the cost of Enoshima, Saikai City, Nagasaki Prefecture”, which is referred to as the second round (the bidding process commenced on 28 December 2022 and closed on 30 June 2023, and now a business operator is being selected). Another major change in the second round of bidding from the first round is that the FIP system will be applied to all four zones.

The government aims to improve the ratio of renewable energy to 36–38% or more by 2030, and to introduce 5.7 GW of offshore wind power by the same year. In order to expand the introduction of offshore wind power, the national and local governments have been actively committed to project formation from an early stage to establish a scheme that enables a prompt and efficient investigation of wind conditions, sea floor soils, etc and ensures performance of the electrical grid (Japanese version of the centralised model). Furthermore, in April 2023, the Fourth Basic Plan on Ocean Policy was approved by the Cabinet, reconfirming that offshore wind power generation is the primary approach for utilising renewable energy as a major power source and is an extremely important measure to achieve carbon neutrality. The plan contains a policy to promote the development of legislation for the expansion of offshore wind power generation to the Exclusive Economic Zone (EEZ) and the technological development towards domestic production, while fully taking into account security and environmental impacts.

In September 2023, public notice and public inspection were made to designate two new sea areas as promotion zones. Additionally, more than one sea area has already been designated as a promising zone which will be a candidate for a promotion zone subject to future public tenders for offshore wind power projects. Thus, it is expected that the use of offshore wind power will continue to expand.

A New Power Source for Decarbonisation

Status of the government policy

In February 2023, the Japanese government formulated the “Basic Policy for Realising GX – Roadmap for the Next 10 Years” (the “GX Basic Policy”) as a policy initiative to achieve carbon neutrality by 2050 and to simultaneously strengthen industrial competitiveness and realise economic growth. In May 2023, the “Act on Promotion of a Smooth Transition to a Decarbonised Growth-oriented Economic Structure” (the “GX Promotion Act”) was enacted to implement the policies set forth in the GX Basic Policy and came into effect on 30 June 2023.

The GX Basic Policy indicates that the following efforts, among others, will be made as measures to shift the industrial and social structure, which has been centred on fossil energy since the Industrial Revolution, to one centred on clean energy (Green Transformation (GX)):

  • to utilise renewable energy as a major power source;
  • to promote the introduction of hydrogen and ammonia as energy sources;
  • to develop the electric power and gas markets to achieve carbon neutrality; and
  • to support the battery industry.

Under the GX Basic Policy and the GX Promotion Act, the following measures will also be taken as part of the “Growth-oriented Carbon Pricing Concept” to make the massive investment (estimated at JPY150 trillion over the next 10 years) through public-private partnerships in order to achieve carbon neutrality by 2050 and while also strengthening Japan’s industrial competitiveness and achieving economic growth.

  • Support for upfront investment using the GX Economic Transition Bonds – Create GX Economic Transition Bonds and issue JPY20 trillion GX Economic Transition Bonds over 10 years from FY2023 to FY2032 to be used by the government as a source of bold upfront investment support.
  • Incentive for GX upfront investment through carbon pricing – Introduce an “emissions trading scheme” together with a “paid auction” for power producers and a “carbon levy”.

The “emissions trading scheme” had not been introduced in Japan, except for some ordinances, but a voluntary emissions trading scheme (GX-ETS) has been launched in the GX League since FY2023. GX-ETS is not a system in which companies are required to participate and is not based on a legal framework, but is characterised by its voluntary participation, in which companies set their own targets and comply with them through their own efforts. The GX-ETS will be launched on a trial basis in the first phase from FY2023 to FY2025, and will be fully operational in the second phase from FY2026. Further, paid auctions for the power generation sector are to be introduced in phases starting from FY2033 and other developments are being considered in the discussions on the GX-ETS system design. It is expected that the trial introduction of the first phase will lead to additional developments to the system.

With regard to the “paid auction” for power producers, the GX Promotion Act provides that, beginning in FY2033, power producers with high carbon dioxide emissions will be allocated a carbon dioxide emission allowance (amount) partially on a charged basis, and that a specific business contribution will be collected for the paid allowances in proportion to the amount of carbon dioxide emissions.

The GX Promotion Act also provides that, beginning in FY2028, a fossil fuel levy will be imposed as a “carbon levy” on business operators that extract and import crude oil, petroleum products, gaseous hydrocarbons (LNG, etc) and coal (“crude oil, etc”) (Article 2, paragraphs 3 and 4 of the GX Promotion Act), in accordance with the amount of carbon dioxide derived from the imported crude oil, etc.

Through these carbon pricing measures, the government intends to boost GX investments.

  • Use of new financing methods – Establish a financing method combining public and private funds (blended finance) to address risks that will not be completely taken by private finance.

With the support of these government policies, it is expected that there will be an increase in the number of situations where project financing will be considered for new power sources, as well as for renewable energy projects.

Storage battery

As the share of renewable energy in the power supply mix is growing, storage batteries have gained more attention as adjustment capability.

Under the revised Electricity Business Act, effective as of 1 April 2023, the operation of discharging electricity for retail consumption by using electric storage facilities was positioned as an electricity generation method. This revised act clarifies the legal status of this arrangement and has led to an increase in the number of businesses where large-scale storage batteries are connected to the power grid.

As grid storage batteries store electricity purchased from the electricity market to resell in the electricity market, there is an issue of how to analyse market volatility risk when considering project financing. However, with the existence of support programmes such as the Long-Term Decarbonisation Power Source Auction (described below), it is anticipated that the number of cases that consider financing in the future will increase.

Hydrogen and ammonia

Hydrogen and ammonia are expected to be utilised in a wide range of fields, including power generation, transportation and industrial sectors, and are gaining attention as one of the breakthrough energies for achieving carbon neutrality that will also contribute to improving self-sufficiency and responding to changes in renewable energy output.

In June 2023, the Japanese government revised its Basic Hydrogen Strategy with a new target of around 12 million tons/year in 2040 for the introduction of hydrogen, while maintaining the existing targets (up to 3 million tons/year in 2030 and around 20 million tons/year in 2050). Further, the 6th Basic Energy Plan states that hydrogen and ammonia will account for about 1% of the power generation mix in FY2030.

For project finance, attention is focusing on thermal power generation projects that use hydrogen and ammonia as a fuel. In addition to technical issues, there are many challenges associated with projects utilising hydrogen and ammonia, such as the need to simultaneously commercialise power generation on the demand side and establish supply chains for hydrogen and ammonia on the supply side. However, the government support, including Long-Term Decarbonisation Power Source Auctions that will stabilise cash flows, will drive an increase in projects that consider financing for power generation utilising hydrogen and ammonia in the medium to long term. Currently, there are projects to retrofit existing coal-fired power plants for ammonia co-firing, prior to hydrogen.

Long-Term Decarbonisation Power Source Auction

The Long-Term Decarbonised Power Source Auction is a bidding system for new investments in decarbonised power sources. It will be introduced to promote new investments in decarbonised power sources in response to the recent problem of supply capacity declining due to the exit of existing power sources and stagnation of new investments, resulting in a tight supply and demand situation for electricity and soaring wholesale market prices. Specifically, a mixed bidding system will be implemented for decarbonised power sources, launching in FY2023 (the first bidding is scheduled for January 2024), and the successful bidders will receive capacity revenues at the fixed cost level for 20 years in principle, thereby providing predictability of long-term revenues for the recovery of massive initial investments.

Sources eligible for the initial auction include new and replacement projects for hydrogen (at least 10%), LNG, nuclear, biomass, geothermal, storage batteries and pumped storages, retrofits to convert to at least 10% hydrogen co-firing, retrofits to convert to at least 20% ammonia co-firing, and retrofits to convert to biomass exclusively.

The basic premise for new investment in ammonia-hydrogen co-firing is to establish a roadmap to mono-firing by 2050, and if efforts to realise the roadmap are not made without a reasonable reason, the contract can be terminated because of a material breach. LNG is subject to the new investment only within a certain period of time in response to the tight supply and demand situation. In relation to carbon neutrality by 2050, a roadmap to mono-firing for ammonia and hydrogen will be required for the ten years after the start of operation.

The successful bidders in the Long-Term Decarbonisation Power Source Auction will, in principle, receive capacity revenues at the fixed cost level for 20 years. This will stabilise revenues for new power sources such as storage batteries, hydrogen and ammonia, and will attract attention as a contribution to the arrangement of project financing.
