Cryptocurrency Laws in Japan: Complete 2026 Guide

Is Cryptocurrency Legal in Japan?

Yes. Japan was the first country in the world to formally recognise cryptocurrency as legal property and establish a comprehensive licensing regime for exchanges. The April 2017 amendments to the Payment Services Act (PSA) defined "crypto-assets" (originally "virtual currencies") and required exchange operators to register with the Financial Services Agency (FSA).

Japan\'s regulatory tone is consistent: welcomed, but tightly supervised after Mt. Gox. The 2014 collapse of Mt. Gox, then handling 70% of global Bitcoin volume, prompted Japan\'s pioneering response. The January 2018 Coincheck hack ($530 million stolen) prompted further tightening: stricter custody requirements, cold-storage mandates, and the Japan Virtual and Crypto Assets Exchange Association (JVCEA) self-regulatory body.

Individual Japanese residents may buy, sell, hold, mine, and self-custody cryptocurrency. Service providers — exchanges, custodians, stablecoin issuers — operate within a tightly defined licensing framework. Tax treatment is famously punitive: gains are taxed as miscellaneous income at progressive rates up to 55%, with no capital-gains preferential treatment. This is the principal reason many Japanese crypto holders advocate for reform.

Payment Services Act and Financial Instruments Exchange Act

Two statutes carry most of the regulatory weight:

• Payment Services Act (PSA) — governs Crypto Asset Exchange Service Providers (CAESPs). Registration with the FSA is mandatory. Requirements include segregated customer assets, cold-storage majority for customer balances, identity verification, internal controls, and JVCEA membership.
• Financial Instruments and Exchange Act (FIEA) — governs security-token offerings and crypto-asset derivatives. From May 2020 most crypto derivatives moved from PSA to FIEA, with stricter conduct and capital requirements.

The 2022 PSA amendments introduced a defined "Electronic Payment Instrument" (EPI) category for fiat-backed stablecoins, restricting issuance to banks, registered fund-transfer service providers, and trust companies. The 2023 amendments brought enforcement of the Travel Rule into PSA.

JVCEA Self-Regulation

The Japan Virtual and Crypto Assets Exchange Association is an FSA-certified self-regulatory body. All FSA-registered exchanges must join. JVCEA sets industry codes covering listing standards, advertising, security, dispute resolution, and customer-asset protection. It has effectively functioned as the "first line" of supervision, with the FSA stepping in for serious enforcement.

One JVCEA process worth noting: token listings. New tokens added to Japanese exchanges must pass JVCEA review for security, governance, and legal characterisation. This has historically constrained the speed of token availability in Japan compared to other markets — and contributed to a "Japan premium" on some new assets.

Japan Crypto Tax — Summary

Japan taxes individual cryptocurrency gains as miscellaneous income (zōzei shotoku) under the Income Tax Act. This places crypto in the most expensive tax category: aggregated with salary and other income, taxed at the progressive national rate (5% to 45%) plus 10% local resident tax, reaching a combined marginal of 55% above ¥40 million.

There is no preferential capital-gains treatment for crypto, no holding-period discount, and limited loss-offsetting (crypto losses cannot offset salary income; can offset other miscellaneous income within the year but cannot carry forward). For high earners, holding crypto in Japan can be more expensive than in most major economies.
