Japan's government on April 10, 2026 officially approved amendments to the Financial Instruments and Exchange Act (FIEA), classifying crypto assets as full financial instruments. Bitcoin, Ethereum, and other digital assets now fall under the same regulatory rules as stocks. It is the most significant change in the legal status of cryptocurrencies in Japan since 2017, when the country was among the first in the world to license crypto exchanges.
What the new amendment changes
Until now, Japan's Financial Services Agency (FSA) regulated crypto under the Payment Services Act, treating digital assets primarily as a payment method rather than an investment vehicle. The new classification moves them into the same category as securities, with matching requirements on transparency, disclosure, and investor protection.
Finance Minister Satsuki Katayama said at a press conference after the Cabinet meeting: "We will expand the supply of growth capital in response to changes in financial and capital markets, and ensure market fairness, transparency, and investor protection." The amendment will take full effect once implementing regulations are finalized.
Japan had been signaling this move since January 2026, when Katayama said the role of exchanges and market infrastructure would be essential for citizens to benefit from digital and blockchain-based assets. The April amendment delivers on that public commitment.
Insider trading ban
One of the sharpest new rules bans buying or selling crypto assets based on material non-public information. Previously, such restrictions applied only to securities. Now, a trader who acts on information about planned listings, mergers, or regulatory decisions before they are made public faces criminal liability - the same as a stock market insider on the Tokyo Stock Exchange.
The amendment also stiffened penalties for unregistered crypto exchanges. Specific fine amounts will be set in implementing regulations, but the direction is clear. Running an unlicensed platform in Japan just became a much more expensive risk.
Annual disclosures for issuers
Companies that issue crypto assets in the Japanese market are now required to publish annual financial disclosures, in line with requirements for publicly listed companies on the Tokyo Stock Exchange. This will affect projects that raised funds from Japanese investors or operate under Japanese jurisdiction.
The rule is particularly relevant for token projects that held ICOs or raised money from Japanese investors during 2017-2021. Many continued operating without any public reporting. The new standard will push them toward compliance or out of the market.
Tax reform and crypto ETFs by 2028
Alongside the reclassification, Japan's government is advancing two separate reforms. First, the maximum tax rate on crypto gains is set to drop to a flat 20% from the progressive scale that could reach 55%. For large holders, the difference in net returns is substantial.
Second, Japan plans to legalize crypto ETFs by 2028. After the US launched spot Bitcoin ETFs in 2024-2025 and drew tens of billions of dollars in the first year, Japanese financial firms are expecting similar demand from local institutional and retail investors - though no products are available yet.
Nomura and SBI in pole position
Among the major financial groups already preparing for the new rules are Nomura Holdings and SBI Holdings. Nomura set up its crypto division, Laser Digital, in 2023 and has backed several Web3 projects. SBI has been building out digital assets through subsidiaries including SBI VC Trade, one of Japan's largest licensed crypto exchanges.
The new legal framework will let them offer clients instruments similar to what US investors now access through Bitcoin-ETFs. The US proved it. Once a regulated and accessible product exists, demand forms fast.
Japan leads Asia again
Hong Kong is issuing crypto exchange licenses, Singapore is drafting stablecoin standards, Australia introduced exchange licensing in 2026. Japan is going further. Classifying crypto as financial instruments represents a qualitatively different level of recognition compared to a simple licensing requirement.
The new status effectively opens the door to Japanese pension funds and insurance companies, whose internal rules had largely blocked them from buying digital assets directly. The institutional capital sitting in those funds runs into trillions of yen. When a portion of it gets access through regulated ETF products, the effect on the market will be noticeable.
