Japan's Diet Passes the FIEA Amendments on Crypto

Japan's Diet completed passage of amendments to the Financial Instruments and Exchange Act on 15 July, when the House of Councillors approved the bill in a plenary session and closed out its progress through both chambers. The amendments formally recognize crypto assets as financial products under the FIEA, the statute that governs stocks and bonds, and lift them out of the Payment Services Act, which had treated them as a means of payment. Gains move into a separate tax category assessed at about 20% from January 2028, insider-trading prohibitions modeled on the equity rules reach token markets, and maximum penalties rise sharply. The law takes effect within one year of promulgation. Much of the operating detail sits in cabinet ordinances and supervisory guidelines that were still unwritten at the time of writing.

A payments statute swapped for a securities statute

The change of statute is the substance of the reform. Under the Payment Services Act, crypto was regulated mainly as a settlement instrument, so the questions the law put to an exchange concerned custody, segregation of customer assets and anti-money-laundering controls. The FIEA governs instruments held for investment. A different set of obligations comes into the frame: disclosure around what is offered and conduct rules on how it is sold, plus market-abuse provisions covering how it trades. Firms handling these assets now sit under the rulebook the Financial Services Agency applies to securities intermediaries rather than to payment businesses, with the same categories of prohibited conduct and the same expectation that material information about a listed asset be public before anyone trades on it.

None of this arrived unannounced. When the lower house passed the bill in June, it already carried the move to the FIEA, insider-trading rules mirroring those for equities, and a ¥2 million cap on investment in unaudited token offerings. The upper-house vote settled only whether the package would clear the Diet in this session. It did.

Out of miscellaneous income, into a flat 20%

Crypto gains in Japan have been taxed as miscellaneous income, a residual category assessed at progressive rates that run as high as 55% at the top. The amendments move those gains into a separate category taxed at roughly 20%, in line with the treatment of listed securities, and let losses be carried forward for three years, so a loss in one year can be set against gains in the following three. That part of the package is scheduled for January 2028, later than the statutory changes themselves. The gap leaves a stretch in which crypto is a financial product for regulatory purposes before it is one for tax purposes.

Insider trading and a ten-year maximum

The insider-trading provisions are drawn from the equity regime. Trading on unpublished material facts is prohibited, with the FSA pointing to listing decisions, insolvency and large transactions as the kind of information that qualifies. Penalties climb with the new classification. The maximum term of imprisonment goes from three years to ten, and the maximum fine from ¥3 million to ¥10 million; coverage of the vote converted the two figures to roughly $18,500 and $61,600 respectively. For an exchange the consequence is concrete, because listing and delisting decisions are made in-house and now sit inside the definition of material non-public information.

ETF listings from 2027 wait on unwritten ordinances

The clearest downstream effect is on exchange-traded products. The Japan Exchange Group is targeting the first crypto ETF listings as early as 2027, with traditional financial institutions expected to act as issuers. Approval of a domestic spot bitcoin ETF has not been confirmed; the reclassification is a precondition, not a decision. The pattern resembles other jurisdictions bringing crypto under a single rulebook in place of a patchwork of adjacent statutes. What stays open is the detail. The law is effective within a year of promulgation, and the specifics are delegated to cabinet ordinances and supervisory guidelines, so the working scope of disclosure duties and the perimeter of the insider-trading rules will be set by secondary rulemaking, not by the text passed this week.
