Japan passes the crypto law traders wanted but its 20% tax could still wait until 2028

Here is the latest from the digital-asset markets: Japan's House of Councilors approved Cabinet Bill 57 by majority vote on July 15, completing Diet passage of legislation that will move regulated crypto activity into the Financial Instruments and Exchange Act. The legal framework is now in place, but traders may still wait until 2027 or 2028 for the new market rules and 20% tax rate to take effect. The official upper-house record says the core crypto provisions take effect on a date set by Cabinet order within one year of promulgation.

Enforcement during 2026 would start the tax rules on Jan. 1, 2027; enforcement during 2027 would move that start to Jan. The Cabinet's timing will decide which calendar applies.
