Japan plans to bring cryptocurrencies under financial-product rules and apply insider-trading restrictions as part of a wide regulatory overhaul, the Asahi newspaper reported on Sunday.
The Financial Services Agency (FSA) is drafting measures covering the 105 cryptoassets listed on domestic exchanges, including Bitcoin and Ethereum. Exchanges would be required to disclose key information on each asset, such as issuer details, underlying technology and volatility risks.
The plan would bar people with non-public information from trading ahead of events such as listings, delistings or bankruptcies, bringing conduct rules closer to those used in Japan’s equity markets.
Tax treatment would also change. The FSA aims to cut the current progressive tax on crypto gains — which reaches up to 55% — to a flat 20% capital-gains rate, matching stock trading. Policymakers hope the simpler system will draw activity back onshore.
Banks and insurers would be permitted to offer crypto through their securities units under the proposal.
The FSA intends to submit legislation in the 2026 ordinary parliamentary session, the report said.
Bloomberg separately reported that Japan Exchange Group is considering tighter oversight of companies increasing their crypto exposure, including stricter backdoor-listing rules and possible additional audits.
