How to buy bitcoin in Japan
Whether buying bitcoin is legal, the compliant steps through an FSA registered platform, and the tax to expect.
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 bitcoin is legal in Japan as of February 2026. The compliant route is a platform registered with the Financial Services Agency (FSA) as a crypto asset exchange service provider, such as bitFlyer, Coincheck, GMO Coin, bitbank, or Binance Japan. Complete identity verification, fund in yen, and keep records. Gains are generally taxed as miscellaneous income for individuals, administered by the National Tax Agency (NTA). This is not investment advice.
Is it legal to buy bitcoin in Japan
Yes. As of February 2026 it is legal to buy, hold, and sell bitcoin in Japan. Bitcoin is treated as a crypto asset under the Payment Services Act, and the Financial Services Agency (FSA) regulates the platforms that sell it. The simplest compliant route is to buy through a platform that is registered with the FSA as a crypto asset exchange service provider.
Registration is a legal requirement, not a marketing badge. Only registered providers may lawfully exchange bitcoin for yen for residents, and operating without registration is a criminal offence. Platforms on the FSA register that serve Japanese residents include bitFlyer, Coincheck, GMO Coin, bitbank, and Binance Japan. Confirm a platform's current registration on the FSA list before depositing funds.
How to buy bitcoin compliantly
In practice the steps are consistent across registered platforms. First, choose an FSA registered provider and confirm it on the FSA list. Second, complete identity verification, since Japanese anti money laundering rules require know your customer checks. Third, fund your account, typically by bank transfer in yen. Fourth, buy bitcoin and review the fees and the spread before confirming. Fifth, decide on custody, either leaving the asset with the registered provider or withdrawing it to a wallet you control.
Tax and record keeping
Buying bitcoin and holding it is not by itself a taxable event. Tax generally arises when you later sell for yen, swap it for another crypto asset, or spend it. As of February 2026, individual gains are generally taxed as miscellaneous income at progressive rates, with a combined marginal rate that can reach roughly 55 percent, administered by the National Tax Agency (NTA). A proposed flat rate of about 20.315 percent was not yet enacted. Keep records of the price, date, and fees for every transaction. This is information, not tax advice. See the Japan tax page for detail.
Bitcoin's price can rise or fall sharply, and this page does not suggest whether to buy. It explains how to do so within Japanese rules if you decide to. Only commit funds you can afford to lose, and confirm the current rules before acting.
