Bottom line: stock-style market rules for crypto

As reported, Japan's bill moving crypto under the FIEA cleared the Lower House on 2026-06-11 and advanced to the Upper House. The core is market-conduct rules that crypto previously lacked: insider-trading prohibitions and issuer disclosure.

Key points

- The bill passed the Lower House and moved to the Upper House (as reported).

- Adds insider-trading penalties for crypto.

- Requires issuer disclosure so investors can judge for themselves.

Why insider rules matter

In equities, trading on undisclosed material information is banned. Crypto has had room for the same abuse around listings and partnerships, so conduct rules are seen as overdue. Reported figures (e.g. penalty levels and disclosure thresholds) are not final until the bill and secondary regulation are fixed.

Not yet enacted

Some thresholds are reported, not confirmed. The flat 20% tax is handled in separate tax legislation. Confirm with the Diet / FSA.

FAQ

Q. Is it law now? A. No — it passed the Lower House; Upper House passage and enforcement come next.

Q. How does it affect ordinary trading? A. It targets trading on undisclosed material information, not ordinary buying and selling.
