Crypto in Japan

Japan recognized Bitcoin as legal payment under the Payment Services Act (PSA) effective April 2017, following the Mt. Gox collapse. The Financial Services Agency (FSA) and its self-regulatory body, the Japan Virtual Currency Exchange Association (JVCEA), oversee crypto exchanges. The PSA mandates exchange registration, capital requirements, and customer asset segregation. In May 2020, the revised PSA and the Financial Instruments and Exchange Act (FIEA) classified crypto assets as financial instruments, subjecting derivatives to FIEA rules. The FSA has issued business improvement orders to exchanges like Coincheck (January 2018) and Binance (June 2021) for non-compliance. Stablecoins are regulated under the PSA as electronic payment instruments, requiring issuers to be licensed banks or trust companies. Japan’s legal framework is among the strictest globally, prioritizing consumer protection and anti-money laundering (AML) under the Act on Prevention of Transfer of Criminal Proceeds.

Japan taxes crypto income as miscellaneous income under the Income Tax Act, with progressive rates up to 55% (including local inhabitant tax). This applies to trading gains, mining rewards, and staking income. Annual reporting is mandatory for gains exceeding JPY 200,000 (approx. $1,400). Losses cannot be offset against other income. The National Tax Agency (NTA) has increased scrutiny, issuing tax audits and penalties for unreported crypto gains, notably against individuals in 2022-2023. In December 2023, the NTA clarified that unrealized gains on crypto held by corporations are taxable at the end of each fiscal year, a rule unique to Japan. The high tax burden has driven traders to offshore exchanges or reduced activity, with the Japan Blockchain Association lobbying for a flat 20% tax rate since 2022, but no legislative change has passed as of 2025.

Japan has approximately 5 million crypto users (4% of population), down from a peak of 6 million in 2021 due to high taxes and market volatility. Institutional adoption remains limited; major banks like Mitsubishi UFJ Financial Group (MUFG) have launched stablecoin pilots (Progmat, 2023), and SBI Holdings operates a crypto exchange (SBI VC Trade). Retail trading volume on domestic exchanges fell 30% in 2023 to JPY 10 trillion ($70 billion), per JVCEA data. Use cases focus on remittances and payments; over 100,000 merchants accept crypto via platforms like Coincheck and BitPay Japan. The Digital Yen pilot, led by the Bank of Japan (BOJ) since April 2023, is in Phase 2 testing with private firms, targeting 2026 for potential issuance. NFT and gaming adoption is nascent, with SBI and GMO Internet launching NFT marketplaces in 2022-2023.
