How to Buy SOL in Japan: A Step-by-Step Guide for Residents
Bottom line: use an FSA-registered exchange
If you live in or are staying in Japan, the safest way to buy SOL is through a crypto-asset exchange registered with Japan's Financial Services Agency (FSA). The flow is the same as anywhere: open an account → complete KYC → deposit yen → buy SOL → optionally self-custody. The Japan-specific parts are the FSA registration check, the documents accepted for KYC, and how crypto is taxed here.

Step 1: Check that the exchange is FSA-registered
In Japan, crypto exchanges must be registered with the FSA, which publishes a list of registered crypto-asset exchange service providers. Registered businesses operate under rules including segregation of customer assets. This article does not recommend any specific exchange — choose based on registration, fees, supported assets (confirm SOL is listed), and usability.
Step 2: Complete KYC
You'll need identity verification (KYC). Typically accepted documents include a residence card, "My Number" card, driver's license, or passport, depending on the exchange. Foreign residents can usually register with a residence card and a Japanese bank account.
Step 3: Deposit Japanese yen
Fund your account by bank transfer or quick deposit. Start with a small, comfortable amount while you learn the process.
Step 4: Buy SOL
| Method | Notes |
|---|---|
| Brokerage ("販売所") | Simple, but the spread (effective cost) tends to be wider |
| Exchange / order book ("取引所") | Often cheaper, but takes some getting used to |
Step 5: Self-custody (optional)
You can leave SOL on the exchange, but to control it yourself, create a wallet such as Phantom and transfer your SOL. Confirm the address, send a small test transfer first, and verify it arrives before sending the full amount. Network fees are a few cents; arrival is usually seconds.
Your recovery phrase is everything
Anyone who knows your wallet's recovery phrase can move your funds. Never share it, avoid screenshots/cloud storage, and beware of scams impersonating support.
Tax in Japan (general)
In Japan, profits from crypto assets are generally treated as miscellaneous income subject to comprehensive (progressive) taxation. Rules depend on your situation, so check the National Tax Agency guidance or a tax professional.
