How to buy Ethereum in Japan
This is general information, not legal, tax, or financial advice. Verify the current rules with a qualified local professional and the official regulator before acting.
Buying Ethereum (ETH) is legal in Japan as of June 2026 and most people do it through an exchange registered with the Financial Services Agency (FSA), such as bitFlyer, Coincheck, or Binance Japan. You open an account, complete identity verification, fund it in yen, and place an order. Buying and holding is not itself taxable, but profit on a later sale, swap, or spend is generally taxed as miscellaneous income. This is general information, not advice.
Is it legal to buy Ethereum in Japan?
Buying, holding, selling, trading, and spending Ethereum is legal in Japan as of June 2026. Japan was one of the first countries to regulate crypto under its Payment Services Act, which defines crypto assets and requires platforms that serve residents to register with the Financial Services Agency (FSA) as a crypto asset exchange service provider. The Japan Virtual and Crypto assets Exchange Association (JVCEA), a self regulatory body, sets industry standards alongside the FSA.
A registered platform may only list a crypto asset that has cleared the screening process overseen by the FSA and the JVCEA, so the set of coins available in Japan is more curated than in some markets. Ethereum is well established and listed across the major registered platforms as of June 2026. The obligations fall on the platforms rather than on the private buyer, who does not need a licence to buy or hold Ethereum.
Ways to buy Ethereum
The most common route is an FSA registered exchange. After you register and verify your identity, you can fund the account by bank transfer in yen, then buy Ethereum at the quoted price plus the platform fee or spread. Platforms let you keep the coin in their custody or withdraw it to a wallet you control. Some platforms offer a simple buy and sell service alongside a separate exchange order book, which usually differ in fees.
Whichever platform you choose, expect to pass a know your customer check, because Japanese anti money laundering rules require registered platforms to verify your identity before you can trade. There is no legal cap on how much Ethereum an individual can buy, but platforms set their own limits by verification level and payment method. Ethereum can also be staked to earn rewards through some platforms and through self custody, and the rewards are generally treated as income for tax.
Tax when you buy and sell
In Japan, profit on crypto held by an individual is generally taxed as miscellaneous income (zatsu shotoku), a position current as of June 2026 and administered by the National Tax Agency (NTA). Buying Ethereum with yen and simply holding it is not itself taxable. Tax generally arises when you sell it for yen, swap it for another crypto, or spend it. Miscellaneous income is added to your other income and taxed at progressive national rates, and with local inhabitant tax the combined top rate can reach about 55 percent.
Because crypto profit is aggregated with salary and other income rather than taxed at a separate flat rate, your effective rate depends on your total income for the year. A reform to tax crypto at a flat rate has been discussed publicly but had not been enacted as of June 2026, so the miscellaneous income treatment continues to apply. Staking rewards and crypto received as payment are generally taxable at their value when received. Keep records of acquisition cost and yen values, and confirm your position with a tax professional before filing. See our crypto tax in Japan page for more.
