Japan's cabinet approved a landmark amendment to the Financial Instruments and Exchange Act on 10 April, elevating crypto from a payment tool to a regulated investment product. The move introduces insider trading prohibitions, mandatory issuer disclosures, and penalties of up to ten years in prison for unlicensed operators.
Japan's cabinet approved an amendment to the Financial Instruments and Exchange Act on 10 April that reclassifies crypto assets as financial instruments — putting them in the same legal category as stocks and bonds for the first time in one of the world's largest crypto markets.
The bill, advanced by the Financial Services Agency, now proceeds to the National Diet for debate and final passage. If enacted, the changes would take effect in fiscal year 2027. Japan has more than 13 million registered crypto accounts, and the FSA receives over 350 fraud-related complaints per month on average — numbers that made the existing regulatory framework, which treated crypto primarily as a payment tool under the Payment Services Act, increasingly untenable.
Finance Minister Satsuki Katayama framed the reform in measured terms: "In response to changes in financial and capital markets, we will expand the supply of growth capital while ensuring market fairness, transparency, and investor protection." The practical implications are considerably sharper than the diplomatic language suggests.
The centrepiece is an explicit prohibition on insider trading in crypto markets. Buying or selling digital assets based on non-public material information will now carry the same legal consequences as insider trading in equities — a gap that has existed since Japan first regulated crypto exchanges in 2017, when the country became one of the first nations to recognise bitcoin as legal tender. The new rules also mandate annual disclosures by crypto issuers, require exchanges to rebrand from "crypto-asset exchange operators" to "crypto-asset dealers," and give the Securities and Exchange Surveillance Commission expanded enforcement powers aligned with traditional securities oversight.
The penalty structure has teeth. Unlicensed operations now face up to ten years in prison and fines of ¥10 million — a significant escalation from the previous maximum of three years and ¥3 million. Courts will also have the power to invalidate transactions with unregistered operators, giving defrauded investors a clearer path to seek refunds.
Japan's approach differs meaningfully from the regulatory strategies emerging in Washington and Brussels. The US is still negotiating the CLARITY Act, which attempts to define which tokens are securities and which are commodities — a distinction Japan has sidestepped by bringing all crypto under the FIEA umbrella. The EU's MiCA framework, meanwhile, created an entirely new regulatory category for crypto assets; Japan chose instead to fold them into existing financial law, a decision that signals confidence in the existing regulatory machinery and impatience with the idea that crypto requires bespoke treatment.
The market implications cut both ways. Greater legitimacy could unlock institutional capital — pension fund allocations, crypto ETFs, and broader participation by domestic financial institutions that have so far stayed on the sidelines. The FSA has been quietly encouraging this trajectory; SEC Chair Paul Atkins' confirmation and the subsequent US pivot toward crypto-friendly regulation removed the last excuse for Japanese regulators to delay their own modernisation.
But compliance costs will rise substantially, and smaller exchanges may not survive the transition. Japan already has some of the strictest operational requirements for crypto businesses in the world — mandatory asset segregation, cold storage rules, and detailed AML/CFT protocols. Layering FIEA obligations on top will consolidate the market around well-capitalised players. The 350-plus monthly fraud complaints suggest that consolidation is overdue.
The tax question remains unresolved, and it is the one aspect of this reform that could determine whether institutional money actually arrives. Japan currently taxes crypto gains at progressive income tax rates of up to 55 per cent — far higher than the 20 per cent flat rate applied to stocks and other financial instruments under the FIEA. Reclassifying crypto as a financial instrument creates a logical — some would say inevitable — case for applying the same 20 per cent rate, but the cabinet's bill does not address taxation directly. That fight will come later, and it will be the one that matters most to the 13 million account holders watching from the sidelines.
