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 finished its progress through both chambers. The amendments formally recognize crypto assets as financial products under the FIEA, the statute that governs stocks and bonds, rather than as a means of payment under the Payment Services Act. Alongside the reclassification, gains move into a separate tax category assessed at about 20% from January 2028, insider-trading prohibitions modeled on the equity rules apply to token markets, and maximum penalties rise sharply. The law takes effect within one year of promulgation, with much of the operating detail left to cabinet ordinances and supervisory guidelines that have yet to be written.

The Reclassification: 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, which brings a different set of obligations into the frame: disclosure around what is offered, conduct rules on how it is sold, and market-abuse provisions covering how it trades. For the firms that handle these assets, the practical effect is that they 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.

The outline was already public. When the lower house passed the bill in June, it 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 whether the package would clear the Diet in this session.

The Tax Change: Out of Miscellaneous Income and 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 allow losses to be carried forward for three years, meaning 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, leaving a period in which crypto is a financial product for regulatory purposes before it is one for tax purposes.

Enforcement: 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 rise 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, which coverage of the vote converted 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.

What Comes Next: Listed Products in 2027 and Ordinances Still Unwritten

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, and the reclassification is a precondition rather than a decision. The pattern resembles other jurisdictions bringing crypto under a single rulebook rather than a patchwork of adjacent statutes. What remains open is the detail: with the law effective within a year of promulgation and the specifics delegated to cabinet ordinances and supervisory guidelines, the scope of disclosure duties and the perimeter of the insider-trading rules will be set by secondary rulemaking rather than by the text passed this week.
