Japan May Move Toward Mandatory Beneficial Ownership Reporting: Key Points From Recent Media Reports

Recent media reports, together with existing government policy documents referring to the possible consideration of new legislation or amendments to improve the identification of beneficial owners of all legal persons, indicate that Japan may be moving toward a mandatory beneficial ownership (BO) reporting regime. Accordingly, the details of the proposed regime, including the scope of covered entities, filing authority, reporting deadlines, update obligations, access rights and penalties, remain subject to change.

The reported proposal should be viewed against the background of Japan’s existing BO framework, the Japan Financial Action Task Force’s (FATF’s) strengthened standards on BO transparency and Japan’s upcoming fifth-round FATF mutual evaluation process, including the scheduled on-site review in June 2028.

Companies with Japanese subsidiaries, joint ventures (JVs) or investment structures should not assume that a new filing obligation is already in force. However, they should consider beginning preparatory work, including mapping direct and indirect ownership, identifying potential beneficial owners under existing Japanese anti-money laundering (AML) concepts and organizing supporting documentation.

Why Is This Happening Now?

The sudden push for this legislation stems from three critical factors:

1. FATF Pressure: In its 2021 mutual evaluation, FATF identified the prevention of misuse of legal persons and arrangements as an area requiring priority attention, and FATF standards on BO have since been strengthened.
2. G7 Alignment: Media reports have described Japan as lagging behind other G7 jurisdictions in establishing a comprehensive BO reporting framework. However, BO reporting regimes differ materially across jurisdictions, and the precise comparative position of Japan should be assessed with care.
3. The 2028 Deadline: Japan’s fifth-round FATF on-site review is currently scheduled for June 2028, with the adoption of the assessment expected in February 2029. A negative assessment could increase regulatory and reputational pressure on Japan’s financial sector and cross-border business. Thus, the government may face strong incentives to demonstrate an operational BO transparency framework. Working backward from the 2028 on-site review, a legislative timetable in late 2026 or 2027 would be consistent with the government’s apparent incentive to demonstrate progress before the FATF review process is fully underway.

Reported Features and Open Issues

Based on the media reports, the proposed legislation may include the following elements. However, none of these points has been confirmed in an official bill or ministry outline:

• Covered Entities: Reports suggest broad coverage, potentially including unlisted companies. Whether the regime would cover godo kaisha, foreign companies registered in Japan, general incorporated associations/foundations, NPOs, partnerships or trusts remains unclear.
• Filing Authority: Reports refer to a public authority such as the Legal Affairs Bureau, but the final filing authority has not been confirmed.
• BO Definition: The new regime may draw on the existing concept under Japan’s AML framework, under which a BO generally includes a person holding more than one-quarter of voting rights, but the final statutory definition remains to be seen.
• Access: Reports suggest rapid access by investigative authorities and relevant ministries. Whether any information would be available to financial institutions, counterparties or the public is unknown.
• Penalties: Reports indicate that penalties for false filings are under consideration. The type and level of penalties, and whether non-filing or late filing would be penalized, remain unclear.

Next Steps and What This Means for Your Business

If the government proceeds as reported, official outlines and potential opportunities for public comment may emerge as the legislative process develops. For foreign investors and multinational corporations with Japanese subsidiaries, JVs or minority investments in Japan, the proposed regime could introduce additional compliance and reporting obligations.

To mitigate risks and ensure a smooth transition, we recommend that companies operating in Japan begin to proactively take the following practical steps:

1. Conduct a Detailed Review of Corporate Structures

Do not rely solely on simple majority-ownership checks. Companies should map out complex international ownership networks to identify ultimate beneficial owners under the proposed “25% voting rights or significant influence” threshold:

• Trace Indirect Ownership: Identify and trace ultimate ownership through intermediate holding companies, investment funds, trusts, nominees or special purpose vehicles (SPVs).
• Assess ‘Control Without Ownership’: Even where no person holds more than 25% of the voting rights, contractual rights, such as director appointment rights, veto rights, financing arrangements or other indicia of de facto control, should be reviewed to determine whether they may point to a natural person who should be identified for BO purposes.

2. Organize and Centralize Key Documentation

Locate and verify the availability of essential corporate documents across all Japan subsidiaries, JVs and minority stakes:

• Document Audit: Ensure that shareholder registries, corporate organizational charts, Articles of Incorporation and Ultimate Beneficial Owner (UBO) identification/KYC materials are accurate and easily accessible.

3. Establish Internal Protocols and Change Management

Prepare internal workflows to handle the ongoing burden of BO maintenance, rather than treating it as a one-time filing:

• Reporting Workflows: Design internal notification flows to capture shifts in BO status immediately, establishing annual re-verification processes.
• M&A Due Diligence: Incorporate BO transparency checks into standard due diligence checklists for future mergers, acquisitions or joint venture formations in Japan.

4. Enhance Counterparty Screening (Economic Security Perspective)

The impact of this law extends beyond your own corporate structure:

• Third-Party Risk: Anticipate that this legislative shift will influence your AML, sanctions and export control screening processes for customers, suppliers and business partners in Japan.

5. Monitor Official Announcements

Stay closely informed as the government transitions from policy intention to an official legislative draft, paying attention to specific filing deadlines and grace periods.

Our Tokyo team will continue to closely monitor the progress of this legislation and provide further updates as soon as the official draft bill is released by the relevant ministries.
