Japan Cryptocurrency Law Classifies Digital Assets as Financial Instruments: Prison Time for Insider Trading

Japan cryptocurrency regulations now officially classify digital assets as full-fledged financial instruments, subjecting them to the same strict rules as stocks and bonds. The country’s parliament has given final approval to amendments to the Financial Instruments and Exchange Act. The Senate’s decision completes a multi-year process of transitioning crypto assets from standard means of payment into a highly regulated investment class.

Authorities have implemented a direct ban on cryptocurrency insider trading for the first time. Exploiting undisclosed information regarding token listings or major transactions now carries a penalty of up to 10 years in prison and a fine of up to 10 million yen. Penalties for operating a brokerage or exchange without a Financial Services Agency license have also intensified, with the maximum prison sentence increasing from three to ten years.

The new mandates require token issuers to publish annual reports and impose investment limits on retail investors dealing with unaudited projects. Regulators justify these measures by citing the need to protect over seven million active crypto account holders from fraud. An expected shift to a flat 20% tax on cryptocurrency profits in 2028 will serve as an additional catalyst for market development. The legislative changes will take effect within a year of their official publication.
