Japan became one of the first countries to regulate crypto when it recognized Bitcoin as a legal payment method on April 1, 2017. The law brought exchanges under anti-money laundering (AML) and know-your-customer (KYC) rules. In July 2026, Japan's parliament approved a law placing crypto under the same law that governs stocks and bonds.
Japan did not start regulating crypto because of a boom. It started because of a failure.
Mt. Gox lost 850,000 BTC in 2014. It closed after months of problems and revelations of insolvency and alleged fraud. The collapse started the debate that led to Japan's first crypto law.
Coincheck's Kagayaki Kawabata told Cointelegraph that many people in Japan distrusted Bitcoin because they thought Mt. Gox was Bitcoin.
Japan responded with an amended Payment Services Act (PSA). The law did not make Bitcoin a currency. It treated virtual currencies as assets that could be used to pay for goods and services. Exchanges had to:
Registration alone did not stop attacks. Each major hack led to tighter rules.
In January 2018, Coincheck lost about $534 million in NEM tokens, then the largest exchange hack on record. In April 2018, the industry formed the Japan Virtual Currency Exchange Association (JVCEA), a self-regulatory organization that sets rules for its own members. In September 2018, hackers took 6,000 BTC, worth about $60 million, from Zaif.
From May 2020, revised rules covered crypto custody and tightened asset segregation and cold-wallet requirements. Cold wallets keep crypto offline, away from internet-based attacks. In May 2024, attackers drained 48.2 billion yen, about $305 million, from DMM Bitcoin.
In August 2026, the FSA and the National Police Agency asked exchanges to add checks on withdrawals flagged for fraud:
Pressure on offshore platforms is also rising. Bitget said in August it would wind down services for Japanese residents, following Bybit's earlier exit after FSA warnings.
2026 brought the biggest change to Japan's crypto rules since 2017.
On July 15, 2026, parliament gave final approval to a law moving crypto from the PSA to the Financial Instruments and Exchange Act (FIEA). The change covers Bitcoin and roughly 104 other assets. It adds insider-trading bans, disclosure rules and firmer action against unregistered operators.
Stablecoins and NFTs stay under the PSA. The main provisions take effect on a date the Cabinet sets, within one year of the law being published. A separate change to Japan's investment trust law is still needed before a spot crypto exchange-traded fund (ETF) can launch.
Japan taxes crypto gains as miscellaneous income, at rates of up to 55%. The new rules set a flat 20% rate, matching the rate on stocks, for eligible tokens sold through registered crypto businesses. Traders also get a three-year loss carry-forward, which lets them offset future gains against past losses. The rate is expected from January 1, 2028. It could start a year earlier if the FIEA changes take effect during 2026.
Only licensed banks, money transfer providers and trust companies can issue yen-pegged stablecoins in Japan. In June 2026, the FSA eased reserve management rules for trust-type stablecoins. In August, it launched a dedicated Crypto Assets and Stablecoins Division.
On September 15, the FSA named on-chain finance a 2026 policy priority, covering payments, securities settlement, tokenized assets and cross-border transfers. Four MUFG group companies began testing Japanese government bond repos on the Canton Network in August. MUFG, Mizuho and Sumitomo Mitsui are also running stablecoin trials under the new framework.
Japan built its crypto rules in response to real failures, starting with Mt. Gox. Exchanges must register with the FSA, follow AML and KYC rules, segregate customer assets and apply anti-fraud withdrawal controls. A law passed in July 2026 will place crypto under the FIEA, with insider-trading bans and disclosure rules. A dedicated FSA division now oversees crypto and stablecoins.
