Japan Cabinet approves omnibus FSA bill amending the Financial Instruments and Exchange Act and Payment Services Act, restructuring crypto-asset regulation, sustainability disclosure, and startup capital formation

Executive Summary

The Japanese Cabinet has approved a Financial Services Agency-submitted bill comprehensively amending the Financial Instruments and Exchange Act (FIEA) and the Payment Services Act, with submission to the National Diet for the current session. The bill restructures the regulatory framework for crypto-assets, codifies disclosure and assurance requirements for sustainability-related financial information, expands the legal architecture for startup capital formation, and revises rules on unfair transactions involving securities. The reforms collectively reposition Japan's capital-markets framework for the next decade of growth-capital deployment, sustainability integration, and digital-asset legitimization, building on the Financial System Council's February 2026 working group report on crypto-asset systems.

Key Regulatory Signals

• Crypto-Asset Regulatory Restructuring: The bill establishes a new statutory framework for crypto-asset activities that distinguishes investment-product crypto-assets from payment-instrument crypto-assets, addressing the gap that has constrained Japan's crypto-asset investment market under the existing PSA-only regime. The framework provides the legal predicate for regulated crypto-asset investment products, institutional custody, and tax-treatment realignment that the Japan Cryptoasset Business Association and similar industry bodies have advocated.
• Sustainability Disclosure and Assurance: The codification of sustainability-related financial information disclosure and assurance requirements operationalizes Japan's alignment with the ISSB sustainability reporting standards (S1 and S2), embedding climate and broader sustainability reporting obligations into the FIEA disclosure architecture. Listed issuers must prepare for phased implementation aligned with the Sustainability Standards Board of Japan's implementation roadmap.
• Startup Capital Formation: The bill expands the legal infrastructure supporting growth capital for startups, including reforms to private placement rules, investment fund structures, and the accredited-investor framework. These changes track Japan's broader strategic objective to deepen the venture capital ecosystem and accelerate the formation of growth-stage Japanese companies in priority sectors including AI, semiconductors, and biotechnology.
• Securities Unfair Transaction Rules: Revised rules on unfair transactions involving securities address market manipulation and insider trading concepts in light of digital trading infrastructure, algorithmic trading, and cross-market information flows. The reforms position the Japan Securities Dealers Association and stock exchange surveillance frameworks for next-generation enforcement architecture.
• Payment Services Act Reform Track: Concurrent amendments to the Payment Services Act align the payment instrument regulatory perimeter with the FIEA crypto-asset reforms, ensuring that the dual statutes operate as a coherent whole rather than as overlapping or contradictory regimes. This reflects the FSA's strategic preference for regulatory simplification under a unified framework rather than parallel statutory tracks.

Regulatory Delta

Japan's capital-markets regulatory framework was last comprehensively recalibrated through the 2017 PSA amendments creating the crypto-asset exchange registration regime and the 2019 FIEA amendments addressing electronically recorded transferable rights. The April 2026 Cabinet bill represents the largest single legislative restructuring since those reforms, integrating crypto-asset systems into the FIEA framework, codifying sustainability disclosure obligations, and expanding the venture capital and startup investment infrastructure within a single legislative vehicle. The bill builds on the Financial System Council's Working Group on Crypto-asset Systems report (16 February 2026) and the FSA's April 2025 discussion paper on crypto-asset regulatory examination, which jointly framed the policy direction now codified in the legislation. By packaging the reforms together, the FSA signals a strategic preference for comprehensive recalibration over incremental amendment, positioning Japan alongside the EU (MiCA + CSRD) and Hong Kong (Stablecoins Ordinance + sustainability reporting) as jurisdictions modernizing their capital-markets architecture as a coherent system rather than asset-class-by-asset-class.
