Crypto Exchanges in Japan for Foreign Residents: How to Open an Account (& the Tax)

Quick answer (30 seconds): Yes — foreign residents can open an account on a Japanese crypto exchange, as long as you pass the standard KYC (identity) check: typically your residence card, a selfie/eKYC, and a Japanese bank account. Stick to FSA-registered exchanges (such as bitFlyer and Coincheck). The single most important thing to understand before you start: in Japan, crypto profits are taxed as "miscellaneous income," not at the ~20% flat rate that applies to stocks — combined with income and resident tax they can reach around 55% at the highest brackets. Crypto is also highly volatile; only risk money you can afford to lose.

Disclaimer: General information, not investment or tax advice. Cryptocurrency is high-risk and you can lose your money. Tax rules are complex and change — confirm your situation with the National Tax Agency (国税庁) or a tax accountant (税理士) before you act.

Can foreign residents open an account?

Yes, if you're a resident with a Japanese address and clear KYC. Japanese exchanges must follow the FSA's anti-money-laundering and Know-Your-Customer rules, so you'll provide:

• Residence card (zairyu card) or a Japanese driver's license,
• a selfie / eKYC verification,
• a Japanese bank account for deposits/withdrawals,
• (often) your My Number for tax reporting.

Tourists / non-residents generally cannot open a Japanese exchange account — these require residency and a Japanese bank account.

Use only FSA-registered exchanges

Any exchange serving residents in Japan must be registered with the Financial Services Agency (FSA), segregate customer funds, and follow AML/KYC and security rules. Two of the biggest:

• bitFlyer — Tokyo-based, founded 2014; one of the most popular and liquid in Japan.
• Coincheck — established 2012; known for a beginner-friendly app.

Others (e.g., GMO Coin) also operate under FSA registration. Avoid unregistered overseas platforms for your Japan-based activity.

How to open an account (typical steps)

1. Choose an FSA-registered exchange and download its app.
2. Register with your email and a strong password.
3. Complete KYC: photograph your residence card, take a selfie/eKYC, and enter your details (often My Number).
4. Link your Japanese bank account and deposit yen.
5. Buy — usually you can start with a small amount; fees and spreads vary by exchange and order type.

⚠️ The tax most foreigners get wrong

This is the part to internalize before you trade:

• In Japan, crypto gains are "miscellaneous income (zatsu-shotoku)" — they are added to your other income and taxed at progressive rates. Combined with resident tax, the top effective rate is roughly 55%.
• This is very different from stocks/NISA, where gains are generally taxed at a ~20% separate rate.
• Taxable events include selling crypto for yen, swapping one coin for another, and spending crypto — not just cashing out.
• Keep detailed records of every transaction; you'll likely need to file a tax return (kakutei shinkoku).

Because the tax treatment is heavy and easy to get wrong, read a dedicated crypto-tax guide and consider a tax accountant — see related guides.
