Japan Tightens Crypto Regulations, Aligns with Global Securities Framework for Enhanced Investor Protection
December 10, 2025
The new regime would require pre-sale disclosures, detailed information on project entities, and external code audits, incorporating feedback from self-regulatory organizations.
Japan is moving to overhaul crypto taxation by adopting a flat 20% rate on gains to align crypto with equities and investment trusts, in a bid to stimulate local trading activity.
Industry responses warn higher compliance costs for exchanges and smaller firms, but there could be long-term benefits through greater institutional participation and market legitimacy.
Approved tokens would receive benefits such as bank custody and clearer compliance rules, while non-whitelisted assets face limited exchange access and stricter oversight.
Monumental tech bets like MON’s potential high-throughput capabilities and strong backers hint at continued crypto infrastructure innovation.
Analysts frame presales as opportunities for early movers while noting the coverage has promotional elements and is not financial advice.
Investors could benefit from greater certainty and easier record-keeping, potentially boosting trading volume and domestic blockchain financing.
The reform shifts regulatory oversight from the Payment Services Act to the Financial Instruments and Exchange Act, signaling tougher investor protections and closer supervision of crypto activities.
Under the current system, crypto profits are taxed as miscellaneous income at rates up to about 55%, which traders view as punitive and discouraging.
Proposed rules for Initial Exchange Offerings include mandatory pre-sale disclosures, identification of core project entities, and independent third-party code audits, with input from self-regulatory bodies.
Regulators would gain stronger tools to crack down on unregistered platforms, including overseas exchanges and certain decentralized ones.
The framework aims to curb insider trading and improve disclosure, aligning with global trends like the EU MiCA and South Korea’s rules, while targeting unregistered and offshore sources.
