How to Buy Bitcoin in Japan: A Beginner's Guide for Residents
Bottom line: use an FSA-registered exchange, start small
If you live in Japan, the safest way to buy Bitcoin is through a crypto exchange registered with Japan's Financial Services Agency (FSA). The flow is: open an account, complete identity verification (KYC), deposit Japanese yen, and buy — often from just a few hundred yen. This guide is education, not advice, and does not recommend any specific exchange.
Key takeaways
- Use an FSA-registered crypto exchange — this is the single most important check.
- KYC requires a valid ID (residence card / My Number card) and usually a selfie (eKYC).
- You can start with a small amount — Bitcoin is divisible to 1/100,000,000 (a "satoshi").
- After buying, learn safe storage; profits are generally taxed as miscellaneous income in Japan.
Step 1: Choose an FSA-registered exchange
Japan regulates crypto exchanges. Confirm the operator is on the FSA's register of crypto-asset exchange service providers before depositing any money. Registered exchanges must follow rules such as segregating customer assets and performing identity checks. Beyond registration, compare:
- Security: two-factor authentication, cold storage, asset segregation
- Fees: trading fees, deposit/withdrawal fees, and the spread
- Usability: app quality, English support (varies by exchange), small-amount buying
Step 2: Complete KYC (identity verification)
You'll register an email, then verify your identity. As a resident, you typically need a residence card (在留カード) or My Number card, plus a selfie or video check (eKYC). This is required under anti-money-laundering law and cannot be skipped.
Residency and documents matter
Requirements differ by exchange and by your residency status. Some exchanges require a Japanese bank account and a local address. Short-term visitors may not qualify. Always check the specific exchange's eligibility rules.
Step 3: Deposit Japanese yen
Fund your account by bank transfer or quick deposit. Only use money you can afford to lose — never living expenses or borrowed funds.
Step 4: Buy Bitcoin (brokerage vs. exchange)
| Method | Traits | Best for |
|---|---|---|
| Brokerage (販売所) | Simple, buy from the operator; wider spread | Quick, small first purchase |
| Exchange / order book (取引所) | Trade with other users; usually lower cost | Keeping costs down |
Many beginners buy a small amount regularly (dollar-cost averaging) rather than timing the market.
Step 5: Store it safely
Leaving coins on an exchange means you rely on that exchange's security and solvency (recall the Mt. Gox collapse). As your holdings grow, consider self-custody with a hardware wallet and back up your seed phrase offline.
Step 6: Understand Japanese tax
In Japan, Bitcoin profits are generally treated as miscellaneous income (zatsu-shotoku) and taxed together with your other income (progressive rates). A salaried worker may not need to file income tax if other income is 200,000 yen or less per year — but residents tax has no such threshold. Rules can change (a 2026 tax-reform outline proposed moving toward separate ~20% taxation, likely from around 2028, but this is not yet enacted). Confirm current rules with the National Tax Agency. Japan's approach also differs sharply from countries where Bitcoin has legal-tender status — Japan treats it purely as a crypto asset, not currency; see where Bitcoin is legal tender worldwide for how that global comparison looks.
