Crypto tax in Japan
Why crypto is taxed heavily and what counts as a taxable event.
Crypto gains are miscellaneous income taxed at your marginal rate (up to ~55% with resident tax); every disposal — including crypto-to-crypto — is taxable.Crypto & FX
Registered exchanges, heavy crypto tax, custody, and leverage risk.
Japan regulates crypto tightly. Only exchanges registered with the FSA and members of the JVCEA may legally serve residents — bitFlyer, bitbank, Coincheck and similar. Registration is the first thing to check; using an unregistered offshore exchange removes your legal protections and complicates tax.
Tax is the decisive factor for most people. Crypto gains are taxed as miscellaneous income (雑所得) at your marginal rate — potentially up to around 55% including resident tax — not the roughly 20% flat rate that applies to listed stocks and NISA. Every disposal, including crypto-to-crypto trades and spending crypto, is a taxable event, so recordkeeping tools matter.
FX (margin foreign-exchange trading) is separate and leverage-driven. Domestic retail FX leverage is capped (commonly 25x), and losses can exceed deposits. Both crypto and FX attract scams — guaranteed-return schemes, fake exchanges, and “recovery” fraud. This section stays educational: registration, tax, custody, records, and risk, with no price predictions or hype.

Frequently asked questions
Which crypto exchanges are legal to use in Japan?
Only exchanges registered with the Financial Services Agency (FSA) and belonging to the JVCEA may legally serve residents of Japan — examples include bitFlyer, bitbank, and Coincheck. Using an unregistered offshore exchange means you lose Japanese legal and consumer protections and can complicate tax and withdrawals. Always confirm an exchange is on the FSA’s registered list before depositing funds.
How much tax do I pay on crypto profits in Japan?
Crypto gains are miscellaneous income taxed at your marginal income-tax rate plus resident tax — combined this can reach roughly 55% at the top, far above the ~20% flat rate on listed stocks. There is no special low rate and, unlike stocks, no NISA shelter. Every disposal is taxable (selling to yen, crypto-to-crypto swaps, and paying with crypto), so you must calculate gains across all transactions. Keep thorough records and consider a tax accountant for active trading.
How do I keep crypto tax records in Japan?
Record every transaction with date, type (buy/sell/swap/spend), amounts, the yen value at the time, and fees, because Japan taxes each disposal and you must compute cost basis (commonly the moving-average or total-average method). Exchange CSV exports plus crypto tax-calculation tools help consolidate activity across platforms. Good records are essential if you are ever asked to substantiate your filing.
How does FX (margin) leverage work for retail traders in Japan?
Domestic retail FX leverage is capped by regulation, commonly at 25x, which limits how large a position your deposit can control. Leverage amplifies both gains and losses, and sharp moves can trigger margin calls or losses beyond your deposit. FX is high-risk and unsuitable for money you cannot lose. Watch for unregulated offshore brokers offering much higher leverage — they remove your protections and are often used in scams.
