Japan's Lower House Passes Bill Treating Crypto as Financial Instruments

Japan's House of Representatives passed a bill on June 11 that moves crypto assets out of the Payment Services Act and places them under the Financial Instruments and Exchange Act, the statute governing stocks and other securities. The change subjects digital assets to insider-trading rules modeled on those already applied to equities, raises the maximum prison term for running an unregistered crypto business from three years to 10, and caps what an investor may put into unaudited token offerings at ¥2 million. The rules are expected to take effect in 2027, CoinDesk reported, and arrive alongside a separate move to tax crypto gains at a flat 20%.

A payment rail becomes a financial instrument

The category an asset sits in determines which questions the law asks about it. A payments statute is concerned mainly with the intermediary: whether the exchange is registered, and whether customer funds are handled properly and transfers screened. A financial instruments statute asks about the asset and the market around it, covering what must be disclosed and how that information reaches investors, plus who may trade on what and when. The move between the two regimes means the conduct standards long applied to listed shares in Japan now attach to tokens, whether or not a given token was ever designed to function as an investment. That reclassification is the substance of the bill. The penalty increases follow from it, not the other way around.

An insider-trading ban drawn from the equity rulebook

Under the Financial Services Agency rules the bill introduces, trading on unpublished "material facts" becomes prohibited, with the concept drawn to mirror the equities regime. The examples cited are listing decisions, insolvency and large trades: categories of information that have often circulated informally in crypto markets and been acted on without legal consequence. An exchange employee who knows a token is about to be listed, or a large holder preparing an unusually big sale, would sit in the same position as someone holding an unannounced earnings figure. How far that reaches will depend on how the FSA defines materiality in a market where disclosure obligations are thinner than for listed companies, and where the issuer is sometimes not a legally identifiable entity at all.

Penalties: three years to 10, and a ¥2 million cap

The enforcement provisions escalate sharply. They read as an attempt to make unregistered operation uneconomic, not merely risky:

Maximum prison term for an unregistered crypto business rises from three years to 10.
Fines of up to ¥10 million, about $62,800.
A ¥2 million investor cap on unaudited token offerings.

The ¥2 million ceiling is the provision most likely to reshape primary issuance. It does not prohibit unaudited offerings; it makes them small. Any project seeking meaningful capital from Japanese investors is pushed toward an audit, and with it toward the disclosure expectations that financial-instrument status carries.

A lower rate traded for tighter conduct

The tax change and the enforcement changes are two halves of a single bargain. CoinDesk framed the package as lower taxes intended to drive growth, and the flat 20% rate is the inducement; the insider-trading rules, the 10-year maximum and the ¥10 million fines are what is being asked in return. That is the bargain. Japan is offering the treatment investors have long sought, crypto gains taxed like other financial assets, on the condition that crypto markets accept the conduct rules those assets carry. Passage in the House of Representatives is not the end of the legislative process. The expected 2027 start date leaves the FSA time to write the operative rules, and that is where the working scope of a material fact and the audit standard for token offerings will actually be set. Whether a 20% rate is enough to keep activity onshore under a heavier compliance load is the question the next year answers.
