Key Takeaways
- Japan passed major crypto market reforms moving trading rules into the FIEA framework.
- The reform adds disclosure and insider trading rules while crypto ETFs still need separate approval steps.
- Qualifying crypto gains could move toward a 20% tax rate once the new framework takes effect.
Updated: August 18, 2026
Japan’s National Diet passed amendments to the Financial Instruments and Exchange Act and Payment Services Act on July 15, 2026, advancing a major overhaul of the country’s crypto market rules.
The legislation was promulgated as Law No. 64 on July 23, 2026, but the main crypto provisions still need to take effect through a Cabinet order.
Crypto Rules Will Move From Payment Law to Market Law
Once effective, the law will move crypto trading regulation from Japan’s Payment Services Act into the Financial Instruments and Exchange Act (FIEA).
That does not make crypto the same as stocks or bonds, but it places crypto-assets inside Japan’s main market-regulation framework as a separate type of financial product.
Japan’s Financial Services Agency (FSA) has pointed to the growing role of crypto as an investment asset, not only as a payment tool. Its materials cite rising domestic crypto accounts, broader investor interest and overseas crypto exchange-traded fund (ETF) listings as reasons for updating the rulebook.
The reform was still a proposal in 2025. It has now passed the Diet, but the core crypto provisions will take effect on a date set by Cabinet order within one year of promulgation, while ETF and tax changes require additional implementation steps.
New Law Expands Token Disclosures and Market Conduct Rules
Once the crypto provisions take effect, the law will introduce disclosure rules for crypto-assets handled by registered crypto trading businesses. Issuers of certain crypto-assets will have to publish information before offerings and provide ongoing updates when material events occur.
The FSA’s explanatory material says required information could include a token’s nature, function, supply, underlying technology and issuer details when an issuer exists. For crypto-assets without a clear issuer, such as Bitcoin (BTC), the duty shifts more toward the trading businesses handling those assets.
The law will also introduce insider trading rules for crypto-assets handled by domestic crypto trading businesses. That closes a gap in Japan’s current regime, where market manipulation rules already existed but direct crypto insider trading rules were not in place.
Crypto ETFs Still Need a Separate Rule Change
The reform improves the legal path for crypto ETFs, but it does not mean Japanese spot crypto ETFs are automatically approved. The FSA’s tax materials say crypto ETFs are currently not possible under existing investment trust rules and would need an amendment to the relevant enforcement order.
That distinction matters because the FIEA reform and ETF approval processes are not the same step. The law creates a stronger market-law framework for crypto-assets, but ETF formation still depends on product-level rules, exchange approval and tax treatment.
Japan is moving closer to the structure used in other large markets, where Bitcoin and Ethereum (ETH) products trade through regulated wrappers.
The domestic process remains cautious, with investor protection and disclosure rules being built before ETF products can reach the market.
Tax Plan Would Apply 20% Rate to Qualifying Crypto Gains
Japan’s tax reform outline would move certain crypto gains from comprehensive taxation to separate self-assessment taxation. The current system can tax crypto gains at up to 55%, while the proposed treatment would apply a 20% rate, excluding the special income tax for reconstruction.
The 20% treatment would apply to certain crypto-assets handled by crypto trading businesses. The FSA’s explanation says the change would begin from January 1 of the year after the revised FIEA takes effect.
The tax plan would also cover certain crypto derivatives and crypto ETFs, assuming the related FIEA and investment trust rule changes are completed. Losses from qualifying crypto transactions would be eligible for a three-year carryforward, bringing them closer to the treatment of listed stocks, ETFs and certain financial derivatives.
Japan Pairs Crypto Reform With Stronger Investor Safeguards
Japan’s reform is not only about ETFs and taxes. The FSA also wants tougher rules for unregistered operators, clearer token information, stronger business controls and better protection against crypto-related fraud.
The law will require crypto trading businesses to meet operational controls, customer asset management rules and safeguards around the tokens they handle. It also brings crypto investment management and crypto investment advice under regulated investment business categories.
Japan is expanding the path to regulated crypto investment products while putting disclosure, market-conduct and investor-protection rules in place.
The result is a reform package that opens the market carefully, with implementation still tied to Cabinet orders, tax rules and product-level approvals.
