Japan

Japan’s white-collar crime enforcement regime is built on the Penal Code (general offences) and a set of special statutes addressing corporate, financial and economic misconduct. Key sources include the following:

Anti-bribery and corruption

• Domestic bribery. Criminalised under the Penal Code (Articles 197 et seq.), imposing liability on both the giver and recipient, as well as relevant intermediaries.
• Foreign bribery. The Unfair Competition Prevention Act (UCPA) prohibits the bribery of foreign public officials in international business transactions, providing for individual criminal liability and corporate fines through dual-liability provisions.

Fraud, embezzlement, and breach of trust

• General offences. Core fraud and property offences, including embezzlement and misappropriation, are principally prosecuted under the Penal Code.
• Director misconduct. Misconduct by directors and officers is addressed under the Penal Code (breach of trust) and the Companies Act, targeting serious forms of corporate disloyalty and self-dealing by corporate fiduciaries.

Financial and securities crimes

• Market misconduct. The Financial Instruments and Exchange Act (FIEA) governs insider trading, market manipulation, and false or misleading statements in statutory disclosure documents.
• Enforcement. The FIEA supports both criminal prosecution and parallel administrative enforcement mechanisms.

Antitrust and cartel conduct

• Antimonopoly Act (AMA). Regulates cartel conduct and bid-rigging.
• Sanctions. Provides for administrative surcharges as a principal tool and criminal sanctions for serious cases, supported by a leniency programme.

Money laundering and proceeds of crime

• Primary statutes. The Act on Punishment of Organized Crimes and Control of Crime Proceeds (APOC) criminalises the laundering, concealment, and handling of criminal proceeds.
• Asset measures. These laws provide mechanisms for freezing, forfeiture and confiscation to target the financial benefits of white-collar crime.

Japan is a party to, and is materially influenced by, several international instruments and standard-setting frameworks that shape white-collar, financial and organised-crime enforcement — most notably in foreign bribery, proceeds-of-crime, mutual legal assistance and asset recovery.

OECD Anti-Bribery Convention

This is the principal external driver of Japan’s anti-foreign-bribery regime, implemented primarily through the Unfair Competition Prevention Act (UCPA). The UCPA criminalises the bribery to foreign public officials and provides for corporate fines via express dual-liability provisions.

United Nations Convention against Corruption (UNCAC)

UNCAC provides a broad anti-corruption benchmark and reinforces expectations around preventive measures and effective investigation. It serves as a basis for international cooperation, including mutual legal assistance in corruption matters.

United Nations Convention against Transnational Organized Crime (UNTOC)

UNTOC frames cooperation tools and informs proceeds-of-crime policy design. It aligns with Japan’s laundering/proceeds regime and supports cross-border investigative cooperation and asset measures.

Japan’s white-collar laws apply primarily to natural persons, with limited, statute-specific corporate criminal liability, and with civil and administrative liability often operating in parallel.

Individual criminal liability

• Natural persons. Criminal liability attaches to individuals who commit, direct, or participate in an offence, including employees, managers and executive officers.
• Sanctions. Depending on the offence, individuals may be subject to custodial penalties and/or criminal fines. Effective 1 June 2025, Japan unified its custodial sentence structure, replacing the former categories of imprisonment with and without work requirements with a single custodial sentence.

Corporate criminal liability (dual-liability)

• Statutory basis. Japan does not recognise a general doctrine of corporate criminal liability; an entity may be punished only where a statute contains an express dual-liability provision.
• Scope. Where applicable, entity liability typically arises when an officer or employee commits the offence in connection with the entity’s business, allowing the imposition of a corporate fine in addition to individual liability.
• Supervision element. Dual-liability provisions commonly allow an entity to avoid punishment if it can demonstrate that it was not negligent in appointing or supervising the relevant personnel. The availability and practical viability of such arguments are statute- and fact-dependent.

Civil and administrative liability

• Director/officer liability (Companies Act). Directors and officers may be civilly liable to the company for breach of duties (Article 423) and, in cases of bad faith or gross negligence, to third parties (Article 429).
• Vicarious liability (Civil Code). Under Article 715 of the Civil Code, employers may be liable for damages caused by employees in the course of business.
• Administrative sanctions. Regulators may impose independent administrative measures, including administrative monetary penalties or surcharges (for example, under the AMA or the FIEA), which may proceed alongside criminal enforcement.

Japan’s jurisdiction in white-collar matters is primarily grounded in the territoriality principle. While limited extraterritorial reach exists, it is offence‑specific and statutorily defined, with certain sector‑specific regimes extending enforcement where conduct has a meaningful nexus to Japanese markets.

Territorial jurisdiction (general rule)

• Penal Code Article 1. Japanese criminal law applies to any person who commits a crime within the territory of Japan, including on board Japanese vessels or aircraft located outside Japan.
• Place of commission. In cross‑border scenarios, determining the “place of commission” may involve complex factual and legal analysis. However, Article 1 itself defines jurisdiction based on territoriality and does not articulate an explicit statutory “effects” test.
• Domestic and foreign entities. Japanese companies, as well as foreign entities operating in Japan, are subject to Japanese criminal and regulatory enforcement to the extent that the relevant conduct occurs within Japanese territory.

Extraterritorial jurisdiction (limited and offence‑specific)

• Nationality and specific bases. The Penal Code provides for extraterritorial application only in limited circumstances and for the offences expressly enumerated in its provisions, notably Articles 2, 3, and 3‑2.
• No general doctrine. Japan does not exercise a general nationality‑based or effects‑based jurisdiction over economic or corporate offences.
• Unfair Competition Prevention Act (UCPA). UCPA criminalises the bribery of foreign public officials. The offence may apply to Japanese nationals who engage in such conduct outside Japan, and corporate fines may be imposed through express dual‑liability provisions where applicable.

Sector‑specific “market nexus” approaches

• Competition law (Antimonopoly Act). Japan has applied the AMA to cross‑border cartel conduct where the arrangement is treated as affecting competition in Japan. The Supreme Court’s 2017 CRT Cartel decision is widely cited as a leading authority in this area.
• Securities regulation (FIEA). In market misconduct matters, Japanese authorities have pursued enforcement against foreign actors where the conduct involved Japanese markets or listed securities. A well-known example is the Securities and Exchange Surveillance Commission’s (SESC) recommendation for an administrative monetary penalty in the Tiger Asia Management market manipulation case.

The principal domestic white-collar offences in Japan are found primarily in the Penal Code, the Companies Act and specialised regulatory statutes, most notably the Financial Instruments and Exchange Act (FIEA). Together, these laws form the core criminal enforcement framework for corporate, financial and economic misconduct.

Bribery and corruption (domestic public officials)

• Offences. The Penal Code criminalises a broad range of public-sector bribery offences, including the acceptance, solicitation or promise of bribes by public officials (Article 197 et seq.) and the giving, offering or promising of bribes to public officials (Article 198).
• Indicative penalties. Giving a bribe is punishable by a custodial sentence (up to three years) or a criminal fine (up to JPY 2.5 million). Acceptance is punishable by a custodial sentence of up to five years, increasing to seven years where the official agrees to perform an act in response to a request.

Fraud and computer fraud

• Offences. Fraud (Article 246) and computer fraud (Article 246-2) are central offences used to prosecute deception-based corporate and financial misconduct under the Penal Code.
• Indicative penalties. Fraud is punishable by a custodial sentence for up to 10 years.

Embezzlement and breach of trust

• Offences and penalties. The Penal Code covers simple embezzlement (Article 252; custodial sentence up to five years), business embezzlement (Article 253; custodial sentence up to 10 years), and general breach of trust (Article 247; custodial sentence up to five years or JPY 500,000 fine).
• Special breach of trust. For directors and officers, the Companies Act (Article 960) imposes a custodial sentence of up to 10 years or a fine of up to JPY 10 million.

Financial and market misconduct (FIEA)

• Offences. The FIEA prohibits core market misconduct, including insider trading, market manipulation, and false or misleading statements in statutory disclosure documents.
• Enforcement. Serious cases may result in criminal prosecution; in parallel, administrative monetary penalty (surcharge) mechanisms are frequently utilised.

The principal Japanese white-collar offence directed at overseas conduct is the bribery of foreign public officials under the Unfair Competition Prevention Act (UCPA). In addition, the Penal Code provides offence-specific extraterritorial jurisdiction over certain serious economic crimes committed abroad by Japanese nationals. Ancillary exposure frequently arises through proceeds-of-crime offences and general complicity principles.

Bribery of foreign public officials (UCPA)

• Offence. The UCPA prohibits giving, offering or promising an improper benefit to a foreign public official for the purpose of obtaining an improper business advantage in connection with an international business transaction.
• Penalties (strengthened effective 1 April 2024):
  • Individuals. A custodial sentence up to 10 years and/or a criminal fine of up to JPY 30 million.
  • Corporations. Fines of up to JPY 1 billion under express dual-liability provisions.

Extraterritorial economic crimes by Japanese nationals (Penal Code Article 3)

• Offence-specific reach. Article 3 of the Penal Code extends Japanese criminal jurisdiction to Japanese nationals who commit certain enumerated serious offences abroad.
• Included Offences. This specifically covers fraud and computer fraud (Articles 246–250), breach of trust (Article 247), and embezzlement in the pursuit of social activities (business embezzlement) (Article 253).
• Penalties. Where prosecuted in Japan, penalties track the same statutory maxima applicable to the corresponding domestic offences.

White-collar crime enforcement in Japan is characterised by a functional division of roles among criminal investigators (the police), criminal prosecutors (the Public Prosecutors Office) and specialised administrative regulators. In financial and competition matters in particular, regulators frequently act as gatekeepers, conducting primary administrative investigations and fact-finding and referring serious cases for criminal prosecution.

Public Prosecutors Office (PPO)

• Prosecutorial authority. As a general rule, only public prosecutors have the authority to institute criminal prosecutions in Japan. Prosecutors also play a central role in supervising and directing investigations, assessing evidentiary sufficiency, and determining whether criminal charges should be brought.
• Special investigation departments. Certain District Public Prosecutors Offices — notably in Tokyo, Osaka, and Nagoya — maintain specialised investigation departments that conduct prosecutor-led investigations into major corruption, large-scale corporate fraud, and other complex economic crimes.

Police (National Police Agency and prefectural police)

• Organisation. Day-to-day criminal investigations are primarily conducted by prefectural police forces. Within these forces, specialised units — commonly housed in the Second Investigation Divisions — handle fraud, embezzlement, commercial bribery and other financial crimes.
• Powers. Police are empowered to arrest suspects and conduct searches and seizures, generally pursuant to judicial warrants. In practice, investigations often rely heavily on voluntary interviews and the voluntary production of documents and electronic data, particularly in complex corporate cases.

Securities and Exchange Surveillance Commission (SESC)/Financial Services Agency (FSA)

• Role. The SESC is the primary investigative body for violations of the Financial Instruments and Exchange Act (FIEA), including insider trading, market manipulation and disclosure-related misconduct.
• Powers and outcomes. The SESC conducts inspections and investigations, including compulsory fact-finding measures under the FIEA’s administrative investigation framework. It may recommend the imposition of administrative monetary penalties (surcharges) to the FSA. Where violations are considered serious, the SESC files criminal complaints with the PPO, possibly triggering criminal enforcement.

Japan Fair Trade Commission (JFTC)

• Role. The JFTC is the principal enforcement authority under the Antimonopoly Act (AMA).
• Administrative powers. The JFTC has broad powers to conduct on-site inspections (including dawn raids), issue cease-and-desist orders, and impose substantial administrative surcharges for cartel and bid-rigging conduct.
• Criminal cases. Criminal prosecution is reserved for the most serious competition law violations and is typically pursued following a formal accusation by the JFTC to the Prosecutor-General.

National Tax Agency (NTA)

• Criminal tax investigations. In particularly malicious cases — such as large-scale tax evasion or fraudulent refund schemes — the NTA conducts criminal investigations through the Criminal Investigation Departments of the Regional Taxation Bureaus.
• Referrals to prosecutors. Where sufficient evidence of criminal tax offences is identified, the NTA formally refers the matter to the PPO for criminal prosecution.

White-collar investigations in Japan are in many cases initiated through several voluntary cooperation channels, including formal criminal complaints, reports under the Whistleblower Protection Act, suspicious transaction reports (STRs), and routine inspections by specialised regulators.

Initiation channels

• Regulatory gatekeeping. Criminal enforcement in securities and competition matters is frequently triggered by formal accusations filed by the SESC or the JFTC. These regulators often conduct the initial administrative fact-finding and, in serious cases, refer matters for criminal enforcement by the Public Prosecutors Office.
• Whistleblowing. Following the 2022 amendments to the Whistleblower Protection Act, internal and external reporting has become an increasingly important source of investigative leads.
• Routine surveillance. STRs submitted by financial institutions provide initial leads for money laundering and other financial crime investigations.

Voluntary self-reporting and cooperation

• Individual voluntary surrender (“jishu”). Under Article 42 of the Penal Code, an individual’s punishment may be reduced if they surrender before being identified as a suspect by authorities. While this statutory reduction is discretionary, jishu may be advanced as a mitigating circumstance depending on the timing, completeness and credibility of the disclosure.
• Competition leniency and cooperation. The Antimonopoly Act features a sophisticated leniency programme. Beyond the order of application, the JFTC operates a Reduction System for Cooperation in Investigation, under which additional reductions may be granted based on the usefulness of cooperation. While this primarily addresses administrative surcharges, criminal referral is reserved for the most serious infringements.
• Prosecutorial cooperation agreements. Under Article 350-2 of the Code of Criminal Procedure, Japan’s “plea bargaining” system allows a suspect or entity to enter into an agreement with prosecutors. The core requirement is providing evidence regarding another person’s or entity’s offence in exchange for non-prosecution, reduced charges or other specified charging considerations.

Response by enforcement authorities

• Prosecutorial discretion. Prosecutors possess extensive discretion to grant a suspension of prosecution even when evidence is sufficient for conviction. In corporate cases, prompt self-reporting, credible remediation and effective cooperation are taken into account in determining whether to pursue entity liability or to resolve the matter without prosecution.

Internal corporate investigations in Japan have become increasingly sophisticated, driven by heightened regulatory scrutiny and strengthened board-level oversight duties. At the same time, the absence of a broad, common-law-style legal professional privilege (LPP) places a premium on careful scoping, disciplined documentation and robust data-handling practices from the outset.

Structuring the investigation

• Independence and third-party committees. In significant matters — particularly those involving senior management, potential market impact or issues of public trust — Japanese companies, especially listed companies, are strongly required to establish an independent third-party committee (daisansha iinkai). The Japan Exchange Group, Inc.’s guidance for listed issuers stresses the importance of prompt, objective and credible fact-finding, which in practice is often operationalised through these committees.
• Soft-law regime. These committees are typically composed of external attorneys, and Certified Public Accountants (CPAs) if it is an accounting fraud case, and are commonly formed with reference to the “Principles for Responding to Corporate Misconduct” issued by Japan Exchange Regulation and the Japan Federation of Bar Associations guidance. The investigation reports are often disclosed publicly to restore market confidence.
• Evidence preservation and digital forensics. In many cases, early preservation (legal holds and forensic imaging) is essential. Although employee cooperation is often obtained on a “voluntary” basis, investigative measures must comply with privacy laws and labour regulations.

Legal professional privilege and confidentiality

• General position. Japan does not recognise a broad attorney-client privilege that automatically shields company-held documents from disclosure in criminal or civil proceedings.
• Secrecy obligations and refusal rights. Attorneys are subject to strict statutory confidentiality obligations. Procedural law provides mechanisms — most notably rights to refuse testimony or the production of materials (“attorney-client secrecy”) — regarding confidential information obtained in professional duties. These are refusal rights held by the professional, not a blanket privilege attaching to the documents themselves.
• Competition-law exception. A narrow, privilege-like protection exists specifically for JFTC investigations under the Antimonopoly Act (AMA). This applies to specified communications with outside counsel concerning legal advice in cartel or bid-rigging matters and is subject to strict segregation requirements.
• Practical implication. Because investigation outputs (e.g. interview memoranda and draft reports) may be subject to seizure in criminal investigations or regulatory inspections, counsel should adopt disciplined documentation practices and clear version control to mitigate disclosure risk.

Critical issues when commencing and conducting investigations

• Whistleblower protection. Investigation governance must incorporate strict anti-retaliation controls. Recent reforms to the Whistleblower Protection Act (promulgated on 11 June 2025 and taking effect on 1 December 2026) materially heighten expectations.
• Data protection. Investigations must comply with the Act on the Protection of Personal Information (APPI). Internal policies should expressly support the collection and review of employee data, and cross-border transfers to foreign headquarters must be managed through appropriate legal mechanisms.

Whistleblowing in Japan is primarily governed by the Whistleblower Protection Act (WPA). The statute protects eligible whistleblowers by rendering retaliatory dismissals void and prohibiting other disadvantageous treatment on the grounds of protected reports, while also establishing expectations for internal reporting systems with confidentiality and other internal compliance programme.

The WPA was recently amended twice, in 2020 and 2025. The 2025 amendment is scheduled to take effect on 1 December 2026, substantially strengthening sanctions, enhancing administrative enforcement and expanding the scope of protected individuals.

Statutory framework and scope

• The WPA applies to disclosures relating to violations of specified laws (i.e. “reportable facts”), provided the report is made without an improper purpose. The list of specified laws covers 506 statutes as of 1 January 2026.
• Protection currently centres on workers, former workers, officers and those of contractor companies. The 2025 amendment expands coverage to include freelancers and independent contractors.

Internal reporting systems and confidentiality

• Mandatory internal reporting systems (300+ employees). Enterprises with more than 300 employees must establish internal reporting arrangements and designate personnel in charge who handle internal reports (“jujisha”).
• Confidentiality. Jujisha are subject to statutory confidentiality requirements regarding the whistleblower’s identity. Violation can lead to JPY 300,000 criminal fine.

2025 amendment highlights

The reform taking effect on 1 December 2026 introduces a shift in the balance of power:

• Retaliatory dismissal or disciplinary action becomes subject to direct criminal penalties for responsible individuals (up to six months’ custodial sentence or a fine). Corporations face fines up to JPY 30 million under express dual-liability provisions.
• Where dismissal or disciplinary action occurs within one year after a protected report, the action is presumed retaliatory. This materially increases the practical evidentiary burden on employers to demonstrate legitimate, non-retaliatory grounds.

Japan’s approach to white-collar enforcement has long combined criminal investigations led by the police and public prosecutors with regulator-driven administrative enforcement, particularly in securities, competition and domestic corruption cases.

Review of key agency activities

• Public Prosecutors Office (PPO). Specialised units, such as the Special Investigation Departments, continue to lead major corruption and complex economic crime investigations.
• SESC (FSA). The SESC remains highly active in enforcing against insider trading, market manipulation and disclosure fraud. In the most recent reporting cycle, the SESC made recommendations for administrative monetary penalty payment orders in 14 market-misconduct cases (including 12 insider-trading cases).
• JFTC. The JFTC has maintained steady enforcement against cartels and bid-rigging. However, priorities have broadened to include:
  • Supply-chain protection. Under the subcontract-payment reforms effective 1 January 2026, the JFTC has placed increasing emphasis on the oversight of pricing practices and unfair trade with small and medium-sized counterparties.
  • Digital platforms. Increased competition oversight of digital-platform conduct and market power, supported by evolving policy tools and guidance targeting big-tech ecosystems.

Despite Japan’s robust enforcement infrastructure, structural, legal and operational hurdles often complicate sophisticated white-collar investigations. These friction points are most acute in matters involving digital evidence, cross-border misconduct or dispersed corporate structures.

Structural and historical constraints

Japanese investigations have traditionally placed substantial weight on written interrogation records and admissions. In complex corporate cases involving massive digital datasets and transaction trails, this “confession-centric” dynamic is often less suited to document-intensive reconstruction and can slow fact development.

A commonly cited procedural constraint is the absence of a general right for counsel to be present during interrogations. This can raise transparency and fairness concerns from an international perspective and influences how parties litigate the reliability and context of statements obtained during the investigative phase.

Legal and procedural limitations

In Japan there is an absence of broad legal professional privilege (LPP) and, generally, a broad attorney-client privilege is not recognised. This complicates internal investigations for multinational enterprises, as interview notes and legal analyses held by the company may be sought or seized in criminal investigations.

The global penalty gap and its strategic implications

A critical “weakness” in the context of a globalised economy could be the relative leniency of Japanese monetary sanctions compared to other major jurisdictions:

• Even after recent statutory increases (including the 2024 UCPA reforms), maximum criminal fines and administrative monetary penalties in Japan may remain significantly lower than the headline outcomes frequently seen in the US or EU.
• The availability of suspended sentences for white-collar offenders may potentially lead to a corporate environment that perceives compliance risk as a “manageable cost”.
• Consequently, companies accustomed to Japanese standards may fail to implement the robust, proactive controls required to survive the aggressive, high-stakes enforcement environments of overseas regulators, creating a “compliance gap” and potentially leading to catastrophic sanctions when they operate abroad.

Japan’s white-collar and corporate-compliance landscape is currently shaped less by the creation of new core offences and more by the rigorous implementation and enforcement of recently enacted frameworks. Key areas include whistleblower protection, economic security and the digitalisation of criminal procedure, alongside intensifying policy pressure regarding supply-chain integrity.

Near-term implementation priorities

• Whistleblower Protection Act (WPA) — 2025 Amendment. This is the most critical reform on the immediate horizon, taking effect on 1 December 2026. The amendment introduces criminal penalties for retaliatory conduct (including corporate fines up to JPY 30 million) and a rebuttable presumption of retaliation if adverse action is taken within one year of a report.
• Security clearance framework. The Act on the Protection and Utilization of Important Economic Security Information (fully operational since May 2025) is now moving into its maturation phase. Companies in strategic sectors are focusing on the operationalisation of personnel screening and the internal handling of sensitive, non-public economic security data.

Corporate Governance Code revision discussions

The next revision of Japan’s Corporate Governance Code is currently underway, reflecting a broader policy push to elevate the quality of governance and compliance. The focus is shifting from formal “comply or explain” adherence toward the substantive effectiveness of internal controls and board oversight. This involves intensifying debates on preventing management override and ensuring that audit functions possess genuine independence.
