Is Bitcoin Legal in Japan?
Japan was the first major country in the world to formally regulate cryptocurrency, doing so in 2017 under the Financial Services Agency (FSA). Bitcoin is classified as a "crypto asset" and is fully legal to hold, trade, and use.
The FSA maintains a whitelist of registered exchanges. Foreign exchanges operating without FSA registration, including Binance and Bybit, have received warning notices from the FSA. While technically accessible, Japanese users use these at regulatory risk.
Japan's crypto market is mature and large — estimated at over 5 million active traders. Major domestic exchanges include bitFlyer, Coincheck, and GMO Coin, but for international access with good liquidity, Kraken (globally regulated, US-based, long track record since 2011) and CoinEx(Asia-friendly, wider coin selection, optional KYC for small amounts) are the top choices.
Japanese Bitcoin law requires exchanges to:
- Register with the FSA as a Crypto Asset Exchange Service Provider (CAESP)
- Segregate customer funds from company assets
- Maintain cold wallet storage for majority of assets
- Implement strict KYC and AML procedures
- Store 95%+ of assets in cold wallets

Japan Bitcoin Tax Guide 2026
Tax Rate
Up to 55%
Tax Authority
FSA
Currency
JPY
Bitcoin profits in Japan are taxed as miscellaneous income— the same category as rental income and freelance work. This is important because:
- Tax rate is 15%–55% depending on total income
- For income over ¥40M, the effective rate reaches 55% (45% national + 10% local)
- Losses cannot be carried forward to next year (unlike stocks)
- Crypto-to-crypto trades are taxable events
- Using Bitcoin to pay for goods is a taxable event
Japan has one of the world's highest crypto tax rates. Long-term investors should consider holding strategy carefully. Unlike many Western countries, Japan does not have a separate capital gains rate for crypto.
