Japanese law does not classify offences as misdemeanours and crimes, although there is a Minor Offences Act. The main piece of legislation is the Penal Code (PC), but many statutes include criminal sanctions. The constituent elements of a crime are that:
A crime must also be “illegal” – ie, excluding self-defence, emergency or other justifiable acts.
Attempted offences are only punished if there is a provision punishing attempts for that specific crime.
Legislation
The main laws and regulations relevant to white-collar crime are as follows.
Corporate Fraud Offences
The main offences relevant to white-collar crime include the following.
Further Offences
Sanctions against white-collar crime also apply to:
All these crimes require intent. To secure the conviction of a company or an individual, the public prosecutor must prove beyond reasonable doubt that a criminal act occurred and that there was criminal intent.
The burden of proof lies with the prosecutors, who must prove in court beyond reasonable doubt that the defendant committed the crime for which they were indicted (Article 336 of the Code of Criminal Procedure (CCP), and Article 31 of the Constitution). There is no statutory presumption mechanism beyond deductions and inferences through case-by-case fact-finding by the court.
Administrative Sanctions
An administrative disposition is valid unless rescinded by the court, so the person who received the disposition needs to file a lawsuit. There is no general rule regarding the burden of proof in administrative litigation, which is determined on an individual legal basis. The standard of proof is “certainty of veracity to such an extent that an ordinary person would not raise doubts”.
The limitation period depends on the type of crime and the amount of the statutory penalty (Article 250 of the CCP), and ranges from one to 30 years (except for offences punishable by death). The limitation period starts running when the criminal act stops (Article 253). Where accomplices are involved, the period starts from when the last criminal act committed by an accomplice has ceased (Article 253). If the offender is abroad, the limitation period is tolled during their time abroad (Article 255).
Article 55 of the CPP clarifies the calculation method for limitation periods under the CCP.
In general, laws and regulations do not apply to the activities of foreign companies outside Japan, as their territorial scope should be limited to Japan. However, the PC provides that it may apply to a person who commits certain categories of serious crimes outside Japan. If only part of the act or the result of a crime occurs in Japan, it is considered as a “crime occurring in Japan” and the PC may apply if a fraudulent act causes damage to a Japan resident.
By contrast, the extraterritorial application of administrative powers is generally not specified. Administrative laws and regulations may generally apply to acts outside Japan if they affect, or have consequences for, persons and properties in Japan.
Co-Operation
Evidence for criminal cases in Japan can be obtained from foreign countries based on a treaty or agreement regarding mutual legal assistance in criminal matters (eg, with the USA, South Korea, China, Hong Kong, the EU, Russia and Vietnam, except for cases that do not constitute a crime under the laws of these countries). For foreign countries without a treaty or agreement, co-operation occurs through diplomatic channels based on reciprocity (the Act on International Assistance in Investigation and Other Related Matters).
Assets derived from criminal activities can be seized abroad based on treaties or agreements and through diplomatic channels. Japan has concluded and ratified the United Nations Convention against Transnational Organized Crime, which allows for requests for assistance relating to organised crime between authorities in signatory countries, without going through diplomatic channels.
Administrative authorities usually share information on a bilateral and multilateral basis.
Blocking Statute
No statute explicitly blocks the assertion of foreign jurisdictions within Japan, but the Act on International Assistance in Investigation and Other Related Matters lists matters for which assistance is not provided.
Extradition
The government has entered into extradition treaties with the USA and Korea. Japan is a party to multilateral treaties with provisions on extradition, such as the United Nations Convention against Transnational Organized Crime and the United Nations Convention against Corruption.
The Extradition Act allows the Minister of Justice to decide on the extradition of fugitive criminals (even voluntarily) subject to review by the Tokyo High Court, except in prescribed cases.
In principle, only individuals are criminally liable under Japanese law, and most related crimes are covered by the PC without dealing with legal entities. A legal entity can only be held criminally liable if there is a specific statutory provision (Article 8 of the PC – the dual-liability provision).
A legal entity can be punished by a fine only after it has been proved that one of its officers or employees has committed a specific crime in connection with its business. While it is possible to punish legal entities only without punishing individuals (provided the individual’s offence is proven), there is no clear policy. In a merger context, the criminal liability of the dissolving company cannot be assumed by the surviving company.
The parent company or group companies of a violating company may be held liable only in cases such as joint tort liability under the Civil Code. Japan has no criminal liability provisions for “failure to prevent”-style offences.
Administrative sanctions (eg, administrative monetary penalties) can be imposed on legal entities without a dual-liability provision (eg, under the Act on Prohibition of Private Monopolisation and Maintenance of Fair Trade, or Anti-Monopoly Act (AMA)).
The court decides the punishment within the parameters set by statutes at its discretion, taking into consideration various factors, such as:
The court may render suspended sentences if certain conditions are met – eg, if the defendant is a first-time offender and is sentenced to imprisonment of not more than three years (Chapter 4 of the PC).
Although the range of parameters is wide, there are no clear guidelines or standards. However, owing in part to the availability of sufficient data on past sentences, punishments in similar cases have so far not significantly varied in Japan.
While this is not explicitly stated in Japanese law, if it can be demonstrated that the company had established an appropriate system to prevent the violation of laws or has made remediation efforts, such actions might influence the amount of any fine.
As part of the sentencing procedure, after examining the evidence, the prosecutors must state their opinion, including the sentence, and the defendants and their attorneys can also state their opinions (Article 293 of the CCP). The court is not bound by these opinions, but in practice a more lenient sentence than that suggested by the prosecutor is often handed down.
There are no rules or guidelines governing the assessment of penalties if a deferred prosecution agreement, non-prosecution agreement or plea agreement is reached.
Civil Remedies
Victims of white-collar offences may seek remedies if the offender’s actions constitute a tort under the Civil Code (Article 709). Proceedings are generally initiated before the district court as the court of first instance, depending on the severity of the matter (otherwise, the summary court for petty claims). Civil proceedings are conducted separately from white-collar crime cases.
The Crime Victims Protection Act allows victims to inspect and copy case records after the first trial date until the conclusion of the case, unless the request is not justified. Theoretically, contractual liability and unjust enrichment can be pursued as civil remedies, but when the issue is whether a white-collar crime has been committed, it is usually sufficient to seek tortious liability. However, there are cases in which contractual liability should be pursued owing to the statute of limitations.
Remission Scheme Against Organised Crime
Property directly damaged by a crime and seized will generally be returned by the court or prosecutor’s office after conclusion of the criminal case. However, it is difficult to return property that cannot be identified as belonging to the victim or others.
In principle, property extorted from a victim as a result of a crime or property derived therefrom is not confiscated (Article 19-2 of the PC; Article 13 of the APOC). However, when the nature of the crime makes it difficult to exercise the right to claim against the offender (eg, when committed by organised crime), or when it is difficult to exercise the right to claim owing to disguised or concealed facts, confiscation of the stolen property is permitted.
Under a restitution order system concerning the confiscation of the proceeds of crime and the collection of equivalent sums, the prosecutor’s office can conduct procedures to issue remission payments to victims, etc, from confiscated or forcibly collected property, based on the Act on Issuance of Remission Payments Using Stolen and Misappropriated Property.
When a current deposit account used for criminal purposes is frozen, the Deposit Insurance Corporation of Japan and the bank where such deposit account is opened may take the initiative of distributing the funds from such account to the victims (Act on Payment of Damage Recovery Benefits From Funds in Deposit Accounts Used for Crime).
Class Actions
US-style class actions are not available in Japan. However, certain consumer organisations certified by the Prime Minister (the Secretary-General of the Consumer Affairs Agency (CAA)) may file actions against business operators to request injunctions to end or prevent violations of the Consumer Contract Act committed by business operators against many unspecified individuals.
Organisations that are specifically certified are entitled to file actions for the “confirmation of common obligations” and take judicial action to ascertain the rights of such consumers. However, they cannot represent consumers without their individual consent.
Two main types of authorities are involved in the investigation and prosecution of white-collar offences and the enforcement of sanctions. The enforcement powers of prosecutors and administrative authorities exist in parallel without hierarchy. However, the prosecutors generally wait for the administrative authorities to file an accusation before prosecuting violations of administrative laws and requesting sanctions.
Authorities With Powers Over Criminal Cases
The police and the public prosecutor’s office have powers over criminal cases. They have the power to conduct compulsory investigations but often make enquiries or interview suspects on a voluntary basis. On top of the principal sentence for a criminal offence, the courts may confiscate the proceeds of crime or collect the cash equivalent. Certain drug-related proceeds are subject to mandatory forfeiture or collection. The prosecutor’s office has special investigation departments in Tokyo, Osaka and Nagoya, and the police have special divisions, although there is no special court for white-collar crimes.
Authorities With Powers Under Administrative Laws and Regulations
Ministries and agencies have authority under administrative laws and regulations.
White-collar crimes are often dealt with by the financial authorities, which have regulatory authority over financial institutions (including banks, insurance and securities companies) to ask questions, conduct site inspections and order the submission of reports and materials. They generally conduct investigations into financial institutions on a voluntary basis to compel them to improve their business procedures in accordance with applicable laws and administrative guidance.
The Financial Services Agency of Japan (FSA) is responsible for ensuring the stability of the financial system, protecting investors and carrying out surveillance over securities transactions. The Securities and Exchange Surveillance Commission (SESC) is entrusted by the FSA with daily market surveillance, inspections of securities firms, inspections of disclosure documents and related activities.
The Japan Fair Trade Commission (JFTC) is also important as an administrative authority with respect to white-collar offences and cases involving AMA infringements.
Various ministries and agencies deal with money laundering, including the National Police Agency, the FSA, the Ministry of Finance and the Ministry of Justice.
The CAA has general regulatory authority over misleading labelling. The competent authorities for individual laws regulating labelling and advertising in specific fields (eg, under the Pharmaceuticals and Medical Devices Act) are also regulatory authorities.
For violations of administrative regulations, penalties are often prescribed instead of administrative sanctions. When the administrative authorities believe a crime has been committed with respect to the laws and regulations under their jurisdiction, they must press charges through the investigative authorities.
Administrative Sanctions
Non-compliance with administrative regulations may give rise to administrative sanctions, including:
Public Policy or Political Pressure
The political neutrality of Japan’s law enforcement authorities is relatively well maintained. However, under democratic principles and based on internal policies, the possibility of selective case handling cannot be ruled out.
In general, the authorities mentioned in 2.1 White-Collar Enforcement Authorities have discretion to initiate an investigation. No specific law generally deals with the initiation of investigations, even though the AMA requires the authorities to initiate an investigation when they accept a report (Article 45). The Administrative Procedure Act (eg, for notice hearings) does not apply to investigations aimed directly at gathering information.
Powers to Conduct Searches and Compel Disclosure
In principle, in criminal cases and having obtained a warrant issued by a court (Article 218 of the CCP), the police or public prosecutors have the power to conduct the necessary searches (including obtaining evidence). The requirement is broad: “when necessary in connection with the investigation of a crime”. Requests for hearings and submissions can also be made on a voluntary basis (Article 197). Rejection of a request may trigger an arrest. Public offices or public or private organisations may be asked to make a report on necessary matters relating to the investigation.
The administrative authorities supervising licensed enterprises (eg, the FSA) usually have the power to conduct on-site inspections. The requirement is broad, as in the case of criminal investigations (eg, for a bank “when it is deemed necessary to ensure the sound and proper operation of the bank’s business”). Administrative agencies cannot use force to conduct investigations, but any avoidance or prevention/blocking of an on-site inspection usually constitutes a crime.
It is often difficult for enterprises to file an action to revoke administrative dispositions, and an investigation cannot end until the court decides to revoke or suspend it. As an alternative to a compulsory investigation, the administrative authorities often ask the relevant enterprises to submit information on a voluntary basis, while a formal report submission order is issued in cases that have attracted public attention.
The administrative authorities can decide to conduct a dawn raid (a customary JFTC practice in cartel investigations), especially when they have concerns about the destruction or concealment of evidence.
The authorities do not have the power to freeze or seize digital asset data itself for investigative purposes. However, as part of criminal proceedings, digital assets or their equivalent monetary value can be confiscated as criminal proceeds under the APOC. CCP amendments will enable seizure through data transfer and broader confiscation provisions (not yet in effect).
Questioning Powers
In criminal cases, the police or public prosecutors can interrogate suspects arrested or detained with a warrant issued by a court (Article 198 of the CCP). The requirement for arrest is “when there is probable cause to suspect that the suspect has committed a crime” (Article 199). Suspects can also be interviewed on a voluntary basis (Article 197).
Plea bargaining (limited to cases involving the criminal conduct of third parties, as opposed to one’s own) was introduced relatively recently (Article 350-2 et seq of the CCP). Prosecutors can grant immunity from prosecution to a witness, although the courts tend to scrutinise the credibility of their testimony and there have only been a few cases.
Arrest and detention are made to prevent escape and the destruction of evidence, and are a means of furthering criminal investigations. They are also used by the police and prosecutors to interrogate suspects and defendants.
The administrative authorities supervising licensed enterprises usually have the power to ask questions and order the submission of reports. The requirements and sanctions for non-compliance are generally the same as for administrative inspections. Enterprises are often interviewed and monitored on a voluntary basis.
In criminal cases, the suspects and the accused have:
These rights are based on the Constitution. Attorney-client privilege is not recognised under Japanese law in a criminal context, although attorneys have the right to object to the seizure of documents, etc, pertaining to their client. In practice, attorneys are not allowed to attend the interrogation of suspects during criminal investigations.
Unlawfully obtained evidence may be excluded by a court, taking into account the seriousness of the illegality and the necessity of preventing procedural violations and solving cases. Appeals against the retention or seizure of evidence can be filed with a court (Article 430 of the CCP).
Attorney-client privilege is not available throughout examinations conducted by the administrative authorities, with the exception of cartel matters under the AMA and related JFTC guidelines. In practice, the administrative authorities do not permit counsel to be present at such examinations.
Power of Arrest and Detention, and Relief
See Questioning Powers, above. An appeal may be filed against a detention order (Article 429 of the CCP). The period of arrest is up to 72 hours, and detention is up to 20 days. There is no right to bail before indictment. When indictment takes place during detention, detention continues after the indictment and can be renewed if deemed necessary by the court. The same applies to cases in which a person is detained after indictment.
The defendant may be entitled to bail with limited exceptions, in particular when there is reasonable cause to suspect that the accused may conceal or destroy evidence (Article 89 of the CCP). A court can also allow a defendant to post bail on its own authority when it deems it appropriate (Article 90). In order to prevent defendants on bail from absconding, the CCP includes:
Not all these provisions adopted in 2023 have yet come into force.
The details have not been made public, but it is understood that the tax and police authorities use AI in investigations (for digital forensics, they appear to use the services of external vendors). No laws or guidelines restrict such use.
Directors’ Duty of Care
There is no specific statutory obligation to conduct an internal investigation, even if there is suspicion of wrongdoing. However, a director’s duty of care to a company could prompt senior management to commence internal investigations. Under the Companies Act, if a director fails to investigate despite being aware of the possibility of misconduct, they may be found to be in breach of their duty to mitigate company losses or damage.
In addition, industry-specific regulations may indirectly compel a company to conduct investigations. For example, when a pharmaceutical company becomes aware of issues relating to the efficacy or safety of its pharmaceutical products, it must report the issue to the authorities and an investigation (even preliminary) must be conducted.
Self-Regulated Organisations
Self-regulated organisations have established their own guidelines, such as the Japan Exchange Regulation (JPX-R) concerning the obligations of listed companies to try to conduct investigations when they become aware of misconduct.
Reports to the FSA
Most regulated firms supervised by the FSA (banks, insurance companies and securities companies) are required to file a report with the FSA when they become aware of a prescribed incident of misconduct, which must include a “summary of the incident”, “analysis of factors leading to occurrence”, “matters addressed” and “details of personnel action”.
Data Protection and/or Labour Laws
Data protection is generally not an issue as long as internal company investigations are legitimate. However, according to case law, employees are not under an unlimited duty to co-operate – they must only do so when it is necessary and reasonable in order to perform their work.
Obligation to Share or Legal Privilege
There is no legal obligation to report the results of an internal investigation to the authorities as a matter of course, but there is also no special legal privilege regarding internal investigations.
Only public prosecutors have the authority to prosecute (Article 247 of the CCP). In most cases, prosecutors ultimately decide to prosecute criminal cases based on the results of a police investigation. However, prosecutors may proceed with investigations independently. If the administrative authorities become aware of the existence of a crime in connection with the laws and regulations under their jurisdiction, they must file a complaint with the police or the prosecutor’s office.
The prosecutor’s office decides at its discretion whether to prosecute by considering (for example):
However, a criminal case will be commenced if the Committee for the Inquest of Prosecution resolves that the case should be prosecuted, even if the prosecutor has decided otherwise.
There are no clear prosecution rules or guidelines.
Under the CCP, there is no deferred prosecution system or non-prosecution agreement scheme; however, see 4.3 Plea Agreements, Co-Operation, Self-Disclosure and Leniency.
In addition to the offences covered by the PC and other laws (see 1.1 Criminal Offences), the CA also imposes sanctions against the fraudulent activities of corporate officers and employees. It specifies many types of corporate crime, including the following.
Special (Aggravated) Breach of Trust
A director can be criminally liable for aggravated breach of trust under the CA if they breach their duties in order to unduly seek their own benefit or in the interest of a third party, or to inflict damage on the company’s assets (imprisonment of up to ten years and/or a fine not exceeding JPY10 million).
Endangering a Company’s Assets
This crime includes:
Other CA Offences
These include:
Fraud and embezzlement are covered by the PC.
General
Various statutes prohibit bribery and classify it as a crime, as follows:
In addition, the Political Funds Control Act and the Public Officers Election Act regulate political contributions.
The National Service Act and the National Public Service Ethics Act regulate the conduct of national public servants and their receipt of benefits from certain persons and organisations. The National Public Service Ethics Board provides guidance in the code of ethics for national public officials regarding gifts, hospitality and other business courtesies, and concerning facilitation payments in an administrative disciplinary context.
Public Officials
The PC prohibits a public official from accepting, soliciting or promising to accept a bribe in connection with their duties. It also prohibits a person from giving, offering or promising to give a bribe to a public official. Employees of state-owned or state-controlled entities – such as the Bank of Japan, national universities and Japan Tobacco – are usually deemed to be public officials and are subject to the bribery provisions of the PC or similar provisions under special laws. Intention to commit the offence (awareness of the bribe) is required.
Unless otherwise provided, the maximum prison term for a person found guilty of bribery is 20 years under the PC. A public officer found guilty of receiving a bribe, excluding specified offences, may be punished with imprisonment with work for a term not exceeding five years. For the specified offences, acceptance of a bribe on request by a public officer may be punished with imprisonment with work for not more than seven years; if the public officer consequently acts illegally or refrains from acting in the exercise of their duty, the prison term will be increased by one to 20 years. A person found guilty of giving, offering or promising to give a bribe may be punished with imprisonment with work for not more than three years or a fine of not more than JPY2.5 million.
A person who jointly commits the crime of bribery or induces another to do so may be punished as severely as the principal. An accessory to its commission is subject to a lesser punishment.
Foreign Public Officials
Japan is a party to the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions.
The UCPA prohibits the payment of bribes to foreign public officials for the purpose of having them act or refrain from acting in a particular way in relation to their duties, or of having them use their position to influence another foreign public official to act or refrain from acting in a particular way to make illicit gains from international business transactions (Article 18(1)).
A violation is subject to imprisonment of up to ten years and/or a fine of up to JPY30 million. If an individual who violates the UCPA’s foreign bribery provision is an employee, agent, officer or director of a company and the bribe is made in connection with the company’s business, the company can be subject to a fine of up to JPY1 billion.
The Ministry of Economy, Trade and Industry (METI) has published best practice guidelines entitled “Guidelines for the Prevention of Bribery of Foreign Public Officials”.
Private Commercial Bribery
No general law prohibits commercial bribery among private persons, but bribery of board members of companies is a crime under the CA. Directors or statutory auditors are prohibited from accepting or soliciting property benefits in connection with their duties, and those who have provided, offered or promised to give such benefits will be punished. The CA also makes bribery or the provision or request of benefits regarding the exercise of shareholders’ rights a crime.
Specific laws regulate the provision of advantages or benefits between private parties. For example, the FIEA generally prohibits Financial Instruments and Exchange Business Operators (FIEBOs), such as securities companies and banks, from providing property benefits to clients to make up for losses in securities or derivatives transactions.
The Cabinet Office Ordinance on financial instruments and exchange business restricts FIEBOs and their officers or employees from providing a special advantage to clients. The Ordinance also restricts the staff of registered credit-rating agencies (CRAs) from receiving, demanding or accepting an offer of money or goods that exceeds JPY3,000 per case from their clients in general. No criminal punishment sanctions these acts, but FIEBOs or CRAs may be subject to administrative action by the regulator.
No statute imposes a specific obligation to prevent bribery and influence peddling, and there is no obligation to maintain a compliance programme to prevent bribery. However, the CA requires the directors of a company to establish internal control systems, including a system to prevent unlawful conduct. Failure to do so constitutes a breach of a director’s duty of care.
There is no systematic market practice in combatting corruption and corporate crime. However, most, if not all, listed companies in Japan have established or strengthened their internal control systems and compliance procedures by, for example:
Insider Trading
The FIEA prohibits:
Regulatory Authorities and Guidelines
The regulatory and supervisory authorities relevant to insider trading and market abuse are the FSA and the SESC (see 2.1 White-Collar Enforcement Authorities), which periodically issue and update FIEA-related guidelines. Self-regulatory organisations – such as the Japan Exchange Regulation (JPX), the Japan Securities Dealers Association (JSDA) and the Japan Investment Advisers Association (JIAA) – publish self-regulatory guidelines for the prevention of insider trading.
Offences
Insider trading offences under the FIEA include the following.
Insider trading by a “Corporate Insider” (Article 166)
A “Corporate Insider” who has come to know of a “Material Fact” pertaining to the business or other matters of a listed company or a listed investment company (each a “Listed Company”), or of a subsidiary of a listed company or an asset management company of a listed investment company, and who makes a sale, purchase or other transfer for value or agrees to a transfer for value of shares of the Listed Company before the Material Fact is publicised, violates the FIEA insider trading rules.
“Corporate Insiders” include:
“Material Facts” include:
Decisions, occurrences, differences in settlement of account information, and the matters covered by the catch-all clause (similar to the above) with respect to the subsidiaries of a Listed Company also constitute Material Facts, as do decisions and occurrences with respect to the asset management company of a listed investment company.
Insider trading in connection with a tender offer (Article 167)
The same punishment for insider trading by a Corporate Insider is imposed on a person who has come to know of a fact concerning the launching or suspension of:
Communicating information and advising on transactions (Article 167-2)
A Corporate Insider aware of a Material Fact must not inform another person thereof and must not advise another person to sell or purchase stock of the subject listed company, for the purpose of allowing such other person to make profits or avoid losses, before such Material Fact is publicised. If such other person commits insider trading after receiving said information or advice, the person who provided information on such Material Fact or advice will be punished.
Insider trading offences are not strict liability offences in terms of criminal liability; criminal intent by the person who has committed the offence must be established. Attempts are not punishable. Insider trading actions can be brought against individuals and corporate bodies.
Penalties
For insider trading, the punishment is imprisonment of up to five years and/or a maximum fine of JPY5 million (Article 197-2(13), (14) and (15)). Property/earnings gained through insider trading will be confiscated, and any shortfall will be collected from the offender (Article 198-2). If insider trading is committed by a company’s representative, agent or employee, said company can be punished with a maximum fine of JPY500 million (Article 207(1)(ii)).
The FSA may order a person who commits insider trading or a person who violates the above-mentioned regulation regarding the communication of information to pay an administrative surcharge (Articles 175-1 and 175-2).
Market Abuse
The FIEA (Article 157) prohibits:
Article 158 prohibits spreading rumours or using fraudulent means, assault or intimidation for the purpose of:
The FIEA prohibits market manipulation. The main acts prohibited as such (Article 159) include:
Penalties
A person who commits market abuse can be punished by imprisonment of up to ten years and/or a maximum fine of JPY10 million (Article 197(1)(v)).
A person who commits market abuse and sells or purchases securities at prices that are the result of market abuse, with the intention of making economic gains, can be punished by imprisonment of up to ten years and a maximum fine of JPY30 million (Article 197(2)).
Property/earnings gained through market abuse will be confiscated, and any shortfall will be collected from the offender (Article 198-2). If the violation is committed by a company’s representative, agent or employee, said company can be punished with a fine of up to JPY700 million (Article 207(1)(i)).
In addition, the FSA may order a person who commits administrative market abuse to pay a fine under the FIEA (Articles 174-1 and 174-2).
Tax evasion is punishable under the law applicable to each type of tax. If a taxpayer under-reports its payable tax amount, fails to file a tax return or fails to pay withholding tax by the due date, the tax authorities can impose additional tax collected as an administrative penalty. Delinquent tax can also be applied.
Under-Reporting
The penalty tax for under-reporting is 10% of the tax increment (difference between unreported and reported taxes) resulting from a correction or an amended return when the original final return was filed on or before the due date. If the tax increment exceeds the tax amount of the original tax return filed by the due date or JPY500,000 (whichever is greater), 15% additional tax is applied to the excess amount.
Notwithstanding the general rules, where a taxpayer who has not been notified of the commencement of a tax audit files an amended tax return voluntarily, additional tax is not applied. If a voluntarily amended return is filed by a taxpayer notified of the commencement of a tax audit without awareness of the possible correction based on the audit, 5% additional tax is applied. If the tax increment exceeds the tax amount of the original tax return filed by the due date or JPY500,000 (whichever is greater), 10% additional tax is applied to the excess.
Failure to File
In case of failure to file a tax return, the extra tax is 15% of the principal amount of tax determined by the tax office or set out in a final or amended return if the final tax return was filed after the due date. Where the principal amount exceeds JPY500,000, the additional tax rate becomes 20% of the excess; for taxes for which returns are due on or after 1 January 2024 and where the principal amount exceeds JPY3 million, the additional tax rate becomes 30% of the excess. An extra 10% is added to those rates if extra tax for failure to file or a heavy additional tax has been imposed within five years regarding the tax in question.
Notwithstanding the general rule, where a taxpayer who has not been notified of the commencement of a tax audit files a tax return voluntarily after the due date, 5% additional tax is applied. If a taxpayer who has been notified of the commencement of a tax audit files a return voluntarily without any awareness of the possible correction or determination based on the audit, 10% additional tax is applied (15% to the excess of the principal tax over JPY500,000).
Withholding Tax
In case of failure to pay withholding tax, 10% of the unpaid amount of the principal tax is added in the case of payment notification after the deadline. However, where a taxpayer voluntarily pays the tax after the due date, the extra tax rate is reduced to 5%.
Tax Evasion
In case of tax evasion, additional penalty tax applies at the rate of 35% for under-reporting tax and for failure to pay withholding tax, and 40% for failing to file a tax return. An extra 10% is added to these rates if either an additional tax for failure to file or a heavy additional tax is imposed within five years regarding the same tax.
In addition, a tax offender may be subject to imprisonment of up to ten years and/or a fine. If the amount of corporation tax evaded exceeds an amount specified under the relevant article (eg, Article 159 of the Corporation Tax Act), the fine may, depending on the circumstances, be reduced to an amount in excess of the specified amount but not more than the amount of corporation tax evaded.
Reporting
In addition to the general self-assessment tax system, residents holding foreign assets above a certain threshold must submit a “Foreign Assets Statement”, and individuals with taxable income and assets above a certain threshold or residents holding assets above a certain threshold must submit a “Statement of Assets and Liabilities”.
Obstruction
In case of audit by the tax authorities, a taxpayer is punishable by imprisonment of up to one year or a fine of up to JPY500,000 if they do not answer, provide false answers or obstruct the audit.
Corporate Duties
A company may be liable to a criminal fine if an officer or employee is found guilty of a corporate income tax offence.
The Companies Act
According to the CA and its implementing regulations, joint stock companies and limited liability membership companies must timely prepare accurate accounting books (Articles 432 and 615), and joint stock companies must publish their balance sheets and, where applicable, their profit and loss accounts (Article 440).
In addition, a director (or other relevant person; the same hereafter) of a company who fails to prepare accounting books or balance sheets properly will be subject to a maximum administrative fine of JPY1 million (Article 976). When a director uses documents containing false statements about important matters when soliciting subscribers for shares of the company, they may be subject to imprisonment with labour for up to five years and/or a maximum fine of JPY5 million (Article 964).
The Financial Instruments and Exchange Act
According to the FIEA and its implementing regulations, a person who conducts a public offering of securities must prepare financial and accounting documentation in accordance with the rules applicable to financial statements (Article 193). These documents must be submitted to the FSA as part of the securities registration statement at the time of a public offering, and annual and semi-annual securities reports must be drawn up and disclosed to the public.
Under the FIEA, failure to submit any required financial statement or report is subject to a penalty, depending on the type of document. For example, a person who initiates a public offering before a securities registration statement has been accepted, or who fails to submit an annual securities report by the prescribed deadline, will be subject to imprisonment with labour for up to five years and/or a maximum fine of JPY5 million (Article 197-2). A person who makes false statements about important matters regarding those documents will be subject to imprisonment with labour for up to ten years and/or a maximum fine of JPY10 million (Article 197-1).
In addition, if the FIEA violation is committed by an officer or employee of a company, the company will also be fined for a violation of:
Furthermore, the violation will be subject to a separate surcharge payment order by the FSA (Articles 172-1 to 172-4).
Cartels
The AMA governs cartels (including bid-rigging), which are prohibited as “unreasonable restraints of trade”, defined as “business activities, by which any enterprise, by contract, agreement or any other means irrespective of its name, in concert with other enterprises, mutually restrict or conduct their business activities in such a manner as to fix, maintain or increase prices, or to limit production, technology, products, facilities or counterparties, thereby causing, contrary to the public interest, a substantial restraint of competition in any particular field of trade” (Article 2(6) of the AMA).
The JFTC can conduct primary investigations and impose cease-and-desist orders and administrative fines (surcharge payment orders). The surcharge amount is 10% of:
Financial gains made for not supplying the goods or services subject to the violation are added to these amounts. In addition, the maximum surcharge amount can be increased by 50% for repeat offenders and those playing a proactive role in its commission/ringleaders. A leniency programme allows the JFTC to factor in the order of leniency applications received and the degree of co-operation, and to award a corresponding discharge of, or discount from, the administrative fines.
Criminal Sanctions
Cartelists can face criminal sanctions. The filing by the JFTC of a criminal accusation to the Prosecutor General is the exclusive means by which a criminal prosecution can be brought against enterprises and individuals for cartel violations (Article 96(1) of the AMA). Violations may result in a maximum fine of JPY500 million for enterprises, or imprisonment of up to five years and a fine of up to JPY5 million for individuals.
Other Unfair Trade Practices
The JFTC imposes administrative fines (pursuant to surcharge payment orders) if an enterprise is found to be engaged in “private monopolisation” or certain unfair trade practices under the AMA. Surcharges are calculated by applying certain rates to the sales of the relevant goods or services during the violation period (up to ten years). In the case of control-type private monopolisation, the calculation method is the same as for cartels. The sales calculation methods and surcharge rates differ according to the type of conduct, as follows.
Criminal sanctions may apply for private monopolisation but have so far never been imposed. Enterprises face a maximum criminal fine of JPY500 million.
The Penal Code
A person who defrauds another person of property can be punished by imprisonment of up to ten years (Article 246 of the PC).
The Act on Specified Commercial Transactions
The Act on Specified Commercial Transactions regulates transactions involving:
Taking door-to-door sales as an example, making misrepresentations about the performance or value of a product is prohibited. Violators may face business improvement, business suspension or business prohibition. They may also be subject to imprisonment of up to three years or a maximum fine of JPY3 million.
The Act Against Unjustifiable Premiums and Misleading Representations
The Act Against Unjustifiable Premiums and Misleading Representations (AUPMR) regulates premiums and representations in connection with transactions of goods and services to ensure fair competition and protect the interests of consumers. It prohibits certain acts punishable by surcharge payment order (Article 8), including:
In case of violation of a corrective order (order for action) (Article 46 of the AUPMR), the penalties are imprisonment of up to two years and/or a maximum fine of JPY3 million. A fine of up to JPY1 million may be imposed directly on a malicious enterprise making representations while being aware that they are improper, without an order for action being issued (Article 48). Cease-and-desist orders can be issued to stop misrepresentations and prevent recurrence. The administrative fine is 3% of sales made during the misrepresentation period.
If the business can prove that it did not know the representation was misleading and that it has seriously considered whether it was misleading, the fine is not imposed. If the business reports the misrepresentation before an investigation is started, the fine is reduced by half. If the business makes a plan to refund consumers to compensate for the misrepresentation, and if the plan is approved by the CAA and implemented by the business, the fine is reduced or eliminated.
Cybercrimes and Computer Fraud
The PC prohibits the creation, provision, release, acquisition and storage of malware with the intention of applying or using such malware in the electronic device of another person. Offenders risk imprisonment with work for up to three years or a fine of up to JPY500,000, or two years’ imprisonment with work or a fine of up to JPY300,000 for acquisition and storage (Articles 168-2 and 168-3).
For the unauthorised acquisition, use or disclosure of trade secrets (including electronically stored secrets), the UCPA imposes imprisonment with work for up to ten years, a maximum fine of JPY20 million, or both (Article 21) (see below).
In the case of phishing and unauthorised access to identifying information, the APUCA imposes imprisonment with work for up to one year or a maximum fine of JPY500,000 (Article 12). Unauthorised access, including hacking, is punishable with imprisonment of up to three years or a maximum fine of JPY1 million.
The following acts are also relevant:
Protection of Company Secrets
The UCPA protects trade secrets and shared data with limited access. A trade secret is technical or business information that is useful for commercial activities and is controlled as a secret and not publicly known. Shared data with limited access is technical or business data that is handled as data to be provided to specific persons on a regular basis, and that is accumulated in substantial quantities by electronic, magnetic or other methods that cannot be recognised by human senses alone (excluding information kept secret).
According to Article 21, a person who uses or discloses a trade secret acquired by the following means can face imprisonment of up to ten years and/or a maximum fine of JPY20 million:
The following individuals will be punished:
The Foreign Exchange and Foreign Trade Act
The Ministry of Finance (MOF) and METI can impose financial/trade sanctions under the Foreign Exchange and Foreign Trade Act (FEFTA). Trade control is exercised through FEFTA-compliant measures, such as:
Furthermore, Japan collects and exchanges information with other countries to combat attempts to circumvent export bans and prevent sanctioned countries from acquiring restricted goods or sensitive technologies through illicit means.
Export Control
The legal structure of Japan’s export control system is a complicated mix of primary and secondary legislation:
The FEFTA defines the basic framework and principles of the control of exports of weapons and dual-use items, as well as technology transfers and the need for a METI licence. Any person conducting a transaction subject to Article 25(1) or 25(4) without obtaining a licence as required therein faces criminal penalties (Article 69-6).
Any person who meets either of the following conditions will be punished with imprisonment of up to seven years and/or a maximum fine of JPY20 million (in some cases, five times the value of the items involved exceeding JPY20 million):
Imprisonment of up to ten years and/or a fine of up to JPY30 million applies to exports of specific technology designated by Cabinet Order as being:
Foreign Direct Investments
Depending on the type of business in which the target entity is engaged or the nationality of the foreign investor, the FEFTA requires a foreign investor to submit a prior notification and/or a post-transaction filing through the Bank of Japan to the MOF and relevant ministries. The FEFTA prohibits certain investments in foreign companies by Japanese investors without the prior approval of the authorities. The violation of such requirements or prohibitions is subject to administrative and criminal penalties.
The Customs Act
Under this Act, the following are subject to administrative and criminal penalties:
Harbouring Criminals and Suppressing Evidence
A person who harbours or enables the escape of another who has committed a crime punishable with a fine or harsher punishment, or who has escaped from confinement, will be punished by imprisonment of up to three years or a fine not exceeding JPY300,000 (Article 103 of the PC).
A person who damages, forges, counterfeits or alters evidence relating to the criminal case of another, or who uses counterfeit or altered evidence, will be subject to the same sanctions (Article 104 of the PC).
Regarding perjury, a sworn witness who gives false testimony can be punished with three months to ten years in jail (Article 169 of the PC).
The APOC contains provisions on special categories of crime by organised crime and on the concealment, receipt and confiscation of the proceeds of a crime.
Under the PC, two or more persons who commit a crime together are deemed to be principals, and a person who induces another to commit a crime may be treated in sentencing as a principal (Articles 60 and 61). An accessory (who aids a principal) is also punishable, but the punishment is less than that of the principal (Articles 62 and 63).
The following laws prohibit or restrict money laundering:
These are supplemented by the Guidelines on Anti-Money Laundering and Combatting the Financing of Terrorism and the related FSA FAQ.
The Japan Financial Intelligence Centre (JAFIC), within the National Police Agency, is the relevant financial intelligence unit (FIU) under the Financial Action Task Force (FATF) regime, collecting and analysing information on money laundering.
The APTCP and FEFTA impose obligations on financial institutions to use certain measures to prevent money laundering and terrorist financing, including:
Non-compliance can lead to administrative sanctions by the relevant authority.
The APOC prohibits certain types of conduct, including the following.
Obtaining bank books or cash cards with the intention of receiving banking services by passing off as another is punishable under the APTCP.
Terrorist Financing
Laws combatting the financing of terrorism (collectively, the “CFT regulations”) include:
These are supplemented by the Guidelines on Anti-Money Laundering and Combatting the Financing of Terrorism and related FAQ issued by the FSA.
JAFIC is also the relevant FIU under the FATF scheme, and collects and analyses information on the financing of terrorism.
The MOF is also in charge of the CFT regulations and has the authority to supervise, monitor and inspect suspicious cross-border financings that may be associated with terrorism under the FEFTA.
The Terrorist Financing Suppression Act prohibits acts relating to financing by persons attempting to carry out terrorist acts or their accomplices, and imposes penalties (Article 2, Paragraphs 2 to 5).
Environmental Pollution
There are no general criminal provisions prohibiting environmental pollution, but penalties are provided for in specific environmental laws (eg, Article 31 of the Water Pollution Control Act; Article 33-2 of the Air Pollution Control Act). Certain penalties can only be imposed if an entity fails to comply with an improvement order issued by the authorities.
Human Rights Violations
There are no criminal provisions prohibiting human rights violations in general. However, the Constitution, the PC, the Labour Standards Act, the Immigration Control Act, the Employment Security Act, the CPA and other laws prohibit violations of personal liberty, human trafficking, forced labour and similar acts, while establishing remedial measures and penalties. Many of these criminal provisions also apply to acts committed by Japanese nationals abroad.
Compliance
As part of compliance, companies are expected to verify their supply chains. In 2022, the government released non-binding “Guidelines on Respecting Human Rights in Responsible Supply Chains”, based on the United Nations “Protect, Respect and Remedy” Framework (UN Guiding Principles) and the OECD Guidelines for Multinational Enterprises, which provide for the identification and assessment of adverse impacts, vulnerable stakeholders, the prevention or mitigation of adverse impacts, etc, across the supply chain.
No specific regulation governs the misuse of AI, algorithmic trading or automated decision-making (the Act on Promotion of Research and Development and Utilisation of Artificial Intelligence-Related Technologies enacted in 2025 does not specify prohibited acts). Those engaging in high-frequency trading activities must generally register (FIEA).
Main Offences
While few criminal cases have been made public, there have been cases involving the fraudulent transfer or misappropriation of cryptocurrency and investment fraud.
Classification
Cryptocurrencies are defined as a type of payment instrument under the Payment Services Act (PSA). Consequently, the FIEA, which protects investors, does not typically apply to their transactions (although it may apply to investment businesses involving cryptocurrencies), impacting enforcement. However, discussions are underway to reclassify cryptocurrencies under the FlEA.
Under the PSA, cryptocurrency exchange operators must register and establish proper systems and comply with AML requirements. Non-compliance may result in corrective orders and the revocation of their registration.
There are no special defences for white-collar offences. In criminal cases, the prosecutor bears the burden of proving all elements of a crime, such as:
There is no general rule regarding the burden of proof in administrative litigation, which is determined on an individual law basis. Aside from simple crimes, defendants often claim that their conduct was legitimate and based on a legitimate business purpose. These claims may be rebutted.
Lack of Intent
All crimes listed in 1.1 Criminal Offences require intent. To secure the conviction of a company or an individual, the prosecutor must prove the occurrence of a criminal act and sufficient criminal intent beyond reasonable doubt. A possible defence could be lack of intent.
Dual-Liability
In principle, only individuals are criminally liable, but a legal person can be held criminally liable if a specific statutory provision exists. A company’s liability could be discharged or mitigated if it can show that it has exercised due care in its appointment and oversight of the individual who may be criminally liable.
Compliance Programme
Regarding the company’s liability in a dual-liability context, the existence of a compliance programme or in-house training could be important to prove the absence of negligence. Moreover, the fact that a company implements such a programme or training may be viewed favourably by the prosecutors or courts. However, very few court cases have involved exemptions.
There are no exempt industries or sectors for the crimes described in 1.1 Criminal Offences.
Bribery of Domestic Officials
There is no definition of a bribe in the PC, but it is generally interpreted as an advantage given to a public official to influence the performance of their duties. A bribe is not limited to a monetary or property benefit, and can include the satisfaction of a demand or desire of the official. Gifts, travel, meals, entertainment or free lease of property are generally viewed as an advantage.
Gifts, gratuities, etc, within the scope of social courtesy are not deemed to be bribes, although the criteria are unclear.
Bribery of Foreign Officials
The UCPA does not expressly allow small facilitation payments. There is no clear “safe harbour” rule for such small payments under the UCPA or the METI guidelines on bribery of foreign officials; provided the prerequisite “to obtain illicit gains in business with regard to international commercial transactions” is satisfied, such payment will constitute a bribe under the UCPA. However, the following acts are less likely to be regarded as bribery:
Safe Harbours and Insider Trading
Certain transactions that are not considered to undermine the fairness and credibility of a securities market are exempt from the FIEA insider trading regulations, including:
Plea Agreements
The plea bargaining system allows a suspect and a defendant to enter into negotiations with prosecutors in the presence and with the consent of their attorneys. Evidence of criminal conduct by, or testimony on the criminal conduct of, third parties (individuals or companies) can be provided in return for:
The system covers white-collar crimes such as fraud, bribery, embezzlement and antitrust offences, as well as certain offences relating to taxation and trading in financial products and instruments.
There are various ways in which an individual or a company can co-operate with prosecutors in relation to third-party suspects, including:
To prevent a co-operating party from providing false information on a third-party suspect in the hope of receiving a reduced penalty, the provision of false information may be subject to criminal sanctions, including imprisonment of up to five years.
Surrender Under the PC
If the perpetrator of a crime denounces themselves before being exposed as a suspect by an investigative authority, their punishment may be reduced. This rule also applies with respect to a crime that cannot be prosecuted without a criminal complaint, and to a person who turns themselves in to a person who has the right to make a criminal complaint (Article 42 of the PC).
Leniency Under the AMA
Cartels and bid-rigging are caught by Articles 3 and 6 of the AMA, which prohibit unreasonable restraints of trade.
The AMA leniency programme operates as a system whereby administrative surcharges are waived or reduced on the condition that the enterprises that have been involved in cartels or bid-rigging voluntarily report these activities to the JFTC. The sooner they report their activities to the JFTC before it initiates an investigation, the more surcharges they will be exempt from. Under the current system, the following applies.
A further discount rate may apply according to the degree of co-operation with the investigation, at a rate depending on the timing of the application. Enterprises reporting a violation before a dawn raid are entitled to a reduction in administrative surcharges of up to 40%, while those applying thereafter are only entitled to a reduction of up to 20%.
JFTC Guidelines clarify how the JFTC assesses an applicant’s level of co-operation.
When more than one enterprise of the same group commits an infringement, group enterprises can file a single joint application, in which case the same leniency status/pecking order is granted to all group enterprises named as applicants on the form.
To be eligible for a reduction, applicants must not be involved in illegal activities after the JFTC has commenced its investigation.
Other Co-Operation or Self-Disclosure
The administrative authorities, prosecutors or courts may also consider co-operation and self-disclosure as a factor to reduce or control (as applicable) administrative dispositions, surcharges, criminal charges or punishment.
The Whistle-Blower Protection Act (WPA) provides that a business operator is not authorised to dismiss or treat a worker (including retired employees and officers) unfavourably based on the worker’s whistle-blowing, nor to claim damages against them for damage suffered by the business operator because of the worker’s whistle-blowing, where:
The WPA was amended in 2025, introducing penalties for individuals who dismiss or discipline whistle-blowers for making public interest disclosures, consisting of imprisonment for up to six months or a fine of up to JPY300,000, and a fine of up to JPY30 million for companies that retaliate against whistle-blowers. However, these provisions are not yet in effect.
Companies must establish a system to appropriately respond to whistle-blowing (an efforts obligation for companies with fewer than 300 employees).
Detailed guidance on how business operators should establish whistle-blowing systems (Guidelines for Appropriate and Effective Implementation of the Whistle-Blowing System) has been issued by the CAA, together with commentaries on the Guidelines. The requirements include having the following in place:
The fact that such an internal whistle-blowing system is established is not a safeguard.
There are no special incentives for whistle-blowers.
Many authorities accept anonymous reports, although anonymous reports have limitations, including details and credibility.
When investigations occur across multiple jurisdictions, defence strategies are affected by factors such as differences in national legal systems (the existence of privilege, double jeopardy, plea bargaining, data protection, etc) and the impact of information sharing between authorities. This includes determining which country’s proceedings should be prioritised.
Important amendments to the CCP and WPA will come into force between 2026 and 2027 (the effective dates are yet to be announced).
The CCP will allow orders to be issued to the custodian of an electronic record to “transfer” such records, with penalties for non-compliance.
The WPA will impose penalties on those who dismiss or discipline employees for making whistle-blower disclosures. It also adds provisions presuming that dismissals or disciplinary actions taken within one year of a whistle-blowing report were motivated by that report.
