Japan's Lower House has passed a bill to regulate cryptocurrencies under the Financial Instruments and Exchange Act (FIEA), the legal framework governing stocks and bonds. The legislation would classify leading digital assets including Bitcoin (BTC), Ethereum (ETH), and XRP as financial instruments if approved by the Upper House. The move aims to bring crypto into the same regulatory structure as traditional markets, introducing strict insider trading prohibitions and enhanced disclosure requirements for exchanges and issuers. Market analyst Xaif Crypto highlighted the development as a fundamental shift in how Japan positions digital assets within its financial system. The proposal also includes tax reform, replacing the current miscellaneous income treatment with rates up to 55% with a flat 20% capital gains tax aligned to traditional investments.
Japan's Lower House Passes Crypto Regulation Bill Under FIEA Framework
The bill passed by Japan's Lower House places cryptocurrencies under the Financial Instruments and Exchange Act, the same legal structure that governs stocks and bonds. If the Upper House approves the legislation, Bitcoin, Ethereum, and XRP would be formally treated as financial instruments rather than loosely regulated digital commodities.
The regulatory shift introduces strict insider trading laws to the crypto sector. Trading on non-public information such as exchange listings or project announcements would be explicitly prohibited, closing long-standing regulatory grey areas in the digital asset space.
Exchanges and issuers would face enhanced transparency requirements under the new framework. Entities would be required to disclose detailed information on token structures, risks, and operations, pushing the market closer to the reporting standards seen in listed equity markets.
Proposed Tax Reform Introduces 20% Capital Gains Rate for Crypto
Crypto gains in Japan are currently treated as miscellaneous income, with rates reaching up to 55%. The proposal replaces this structure with a flat 20% capital gains tax, aligning digital assets with traditional investments.
The tax change makes participation more attractive for both retail and institutional investors. The flat rate removes the significant tax burden that has applied to crypto gains under the miscellaneous income classification.
Japanese Banks Develop Stablecoin for Fiscal 2026 Launch
Japan's three largest banking groups — MUFG, Mizuho, and SMBC — are developing a jointly issued stablecoin project. The banks are targeting live commercial use by fiscal 2026.
The stablecoin initiative underscores convergence between traditional finance in Japan and blockchain-based settlement systems. The project represents institutional movement toward integrating digital assets into Japan's broader financial ecosystem.
Bill Awaits Upper House Approval to Become Law
The bill has passed the Lower House and now moves to the Upper House for debate and approval. The legislation is not yet law.
The regulatory framework positions crypto as a financial category built for institutional participation rather than a speculative asset class. The level of regulatory clarity typically draws in banks, asset managers, and corporates that have stayed on the sidelines due to uncertainty.
