Is OKX available in Japan?
OKX serves residents of Japan through OKCoin Japan K.K., which now operates under the OKJ brand and is registered with the Financial Services Agency (FSA). The global OKX.com platform is not the route for Japanese residents, who are directed to the local registered service. Confirm the current asset list and products on the platform before acting.
Information, not advice. 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.
How we checked this. We set this status by reading the platform's own terms of use and country eligibility, and the public register kept by the named regulator, then dated the result. Availability can change, so confirm directly with the platform and the regulator before acting. As of 26 June 2026.
As of June 2026, OKX is available to residents of Japan through its local entity OKCoin Japan K.K., which rebranded to OKJ in August 2024 and is registered with the Financial Services Agency (FSA). The local service received full regulatory approval reported in 2025 and ranks among the larger registered exchanges in the country. Japanese residents are served by the OKJ platform rather than the global OKX.com site, with assets approved for the Japanese market, so confirm the current offering before acting.
Availability for Japanese residents
As of 19 June 2026, OKX serves residents of Japan through OKCoin Japan K.K., which operates under the OKJ brand after rebranding from OKCoin Japan in August 2024. OKJ is on the Financial Services Agency (FSA) register of crypto asset exchange service providers, and reporting in 2025 described the local entity receiving full regulatory approval and ranking among the larger registered exchanges in Japan.
Japan regulates crypto exchanges under the Payment Services Act, and only entities on the FSA register may serve residents. The global OKX.com platform is not the compliant route for Japanese residents, who are directed to the OKJ service. Availability runs through the registered Japanese entity, not the international site.
The assets and products offered to Japanese users are shaped by the local listing process and FSA rules, so they differ from the global platform. Confirm the current asset list and any product limits on OKJ itself before acting.
Access, KYC, and products
OKJ operates a custodial model, holding the assets in your account on your behalf. Japanese residents fund accounts in Japanese yen through domestic bank transfer methods, and identity verification (know your customer, or KYC) under Japanese rules is required before trading. Onboarding includes anti money laundering checks consistent with the Payment Services Act.
Products are focused on spot trading of assets approved for the Japanese market. Some products offered on the global OKX platform, such as certain derivatives, are not offered to Japanese residents through the local entity. Treat the OKJ service as the relevant one and confirm what is offered on the platform.
How crypto is taxed in Japan
Japan currently taxes crypto gains for individuals as miscellaneous income under the rules administered by the National Tax Agency (NTA). Progressive rates combined with inhabitant tax can reach roughly 55 percent at the highest band. A 2026 Tax Reform Outline released on 19 December 2025 proposes a separate flat rate of about 20 percent on specified crypto assets and a three year loss carryforward, but that change depends on legislation and is not yet in force.
Treatment depends on personal circumstances and the framework is changing, so confirm the current position with the National Tax Agency or a qualified professional. See the Japan crypto tax page for a fuller explanation. This is general information, not tax advice (as of 19 June 2026).
Several platforms hold Financial Services Agency registration to serve Japanese residents. Availability and asset lists vary, so compare the exchanges that are genuinely available in Japan before you choose.
Every availability status here is dated and checked against the named regulator's public register. We never place a link to a platform where it is not available.
