Japan Cabinet Reclassifies Crypto as Financial Instruments Under FIEA - Historic Regulatory Shift

Japan's Cabinet officially reclassified 105 cryptocurrencies including BTC and ETH as financial instruments under the Financial Instruments and Exchange Act (FIEA), effective April 2026. Key changes: insider trading bans with prison penalties up to 10 years (previously 3 years), mandatory disclosure requirements for all listed tokens, market manipulation rules, and flat 20% capital gains tax (reduced from as high as 55%). Crypto asset providers must comply with OECD CARF AML/CFT standards. FSA released cybersecurity guidelines requiring mandatory self-assessments and threat-led penetration testing for major platforms.
