Crypto in Japan

How buying works here

Buying crypto in Japan means using an exchange registered with the Financial Services Agency as a crypto-asset exchange service provider under the Payment Services Act. The agency publishes the register, so you can check any platform before you open an account (source: Financial Services Agency, licensed crypto-asset exchange service providers). Registered exchanges also belong to the Japan Virtual and Crypto assets Exchange Association, which screens tokens before members may list them.

Two consequences follow for a buyer. First, your choice is narrower than in most large markets, because global platforms that have not registered cannot serve you. Kraken states that it does not serve clients or accept deposits from Japan (source: Kraken support, availability of Kraken clients by country). Second, the token menu is curated. The association screens listings and sets rules on customer asset segregation, margin trading and solicitation, so a token that trades freely offshore may simply never appear on a Japanese cex (source: Japan Virtual and Crypto assets Exchange Association).

A larger change is in motion. On 15 July 2026 the Diet passed an act amending the Financial Instruments and Exchange Act and the Payment Services Act to move crypto-assets under securities-style regulation, including rules against unfair trading. It was promulgated on 23 July 2026 and takes effect on a date to be set by cabinet order within a year (source: Financial Services Agency, Diet materials). As of September 2026 those provisions are not yet in force, so the current registration regime is still what governs your account.

Payment rails and banks

Yen funding runs through the registered exchange, not around it. Because registration attaches to any firm exchanging crypto for yen, transferring it, or holding it for customers, every legitimate yen on ramp off ramp in Japan sits inside a registered entity supervised by the Financial Services Agency. Customer asset segregation is one of the association rules those firms operate under, so your yen balance and your tokens are meant to be held apart from the exchange's own money.

We were unable to retrieve current deposit documentation from a Japanese exchange during this review, so we are not stating which banks, transfer networks, fee levels or deposit limits apply to a specific platform. We are verifying them.

Japan also has a yen-denominated stablecoin track under the Payment Services Act, but we could not confirm from a primary source which yen tokens are currently issued and available to retail buyers, so we make no claim about them here.

Exchanges people use

Bitbank is the platform in our set with a confirmed Japanese registration, and most global platforms we track are not options here.

Japan has a substantial domestic exchange sector beyond Bitbank, and the Financial Services Agency register is the authoritative list of which firms are permitted to serve you. We are working through that register and have not yet verified individual entries, so we are not naming other platforms until each one is sourced. The list we have published so far is at Exchanges available in Japan, and a first-purchase walkthrough is at Buy Bitcoin in Japan.

Taxes in practice

Japan taxes crypto profit harder than most comparable markets, and the reason is categorical rather than rate-driven. The National Tax Agency treats profit from crypto-assets as miscellaneous income, not as a separate capital gain (source: National Tax Agency, guidance on crypto-asset income). As of September 2026 that means the profit is added to your other income and taxed at Japan's progressive national income tax rates, which reach 45 percent at the top band, with local inhabitant tax charged on top.

There is one useful threshold. A salaried employee whose total side income, including crypto profit, stays at or below 200,000 yen for the year generally does not have to file a return for it (source: National Tax Agency). Above that, you file.

A law promulgated on 31 March 2026 would move crypto to a separate 20 percent tax, which would align it with listed securities and cap the marginal rate. It has not taken effect (source: National Tax Agency and Financial Services Agency materials). Do not plan around the 20 percent figure until a commencement date is set.

Common problems

The most common practical problem is discovering, after reading a global guide, that the exchange it recommends will not open an account for you.

The second is the token gap. Association screening before listing means new tokens reach Japanese exchanges later than they reach global ones, if they arrive at all.

The third is tax surprise. Because profit lands in miscellaneous income at marginal rates, a good year of trading can push your total income into a higher band and raise the tax on your salary as well as on your gains. Track your cost basis as you go rather than reconstructing it in March.
