Converting crypto casino winnings to Japanese Yen requires three steps: withdraw crypto from the casino to a Japanese exchange, sell the crypto for JPY, and transfer JPY to your bank account. The entire process takes 30 minutes to 2 hours depending on the cryptocurrency and exchange used. GMO Coin is the best exchange for this process due to its free crypto deposit fees and free JPY bank withdrawals.
Withdrawal Method Comparison
| Method | Casino to Exchange | Sell to JPY | Bank Withdrawal | Total Time | Total Fees |
|---|---|---|---|---|---|
| BTC via GMO Coin | 10-30 min | Instant | Same day | 1-2 hours | ~¥0 (free) |
| BTC via bitFlyer | 10-30 min | Instant | Same day | 1-2 hours | ~¥550 |
| LTC via GMO Coin | 2-5 min | Instant | Same day | 30-60 min | ~¥0 (free) |
| ETH via Coincheck | 5-15 min | Instant | Next day | 1-24 hours | ~¥1,407 |
Step 1: Withdraw Crypto from Your Casino
Log into your crypto casino (Stake">Stake 9.5/10, BC.Game">BC.Game, etc.) and navigate to the withdrawal section. Copy your exchange's deposit address — for GMO Coin, find this under the "deposit" tab for your chosen crypto. Paste the address into the casino withdrawal form, enter the amount, and confirm. Most casinos process withdrawals instantly or within 10 minutes.
Step 2: Sell Crypto for JPY on Your Exchange
Once the crypto arrives at your exchange, sell it for JPY. Use the exchange's trading interface (取引所) rather than the instant sell (販売所) to minimize spread costs. On GMO Coin, place a limit sell order for the best price. On bitFlyer, use the Lightning Exchange. The sell is executed instantly for market orders.
Step 3: Withdraw JPY to Your Bank Account
Transfer your JPY balance to your registered bank account. GMO Coin offers free bank withdrawals to any Japanese bank. bitFlyer charges ¥220-¥550 depending on the bank. Coincheck charges ¥407. Most withdrawals are processed same-day if submitted before the cutoff time (typically 15:00 JST).
Choosing the Best Cryptocurrency for Withdrawals
Litecoin (LTC) is the fastest option, with blockchain confirmations in 2-5 minutes versus 10-30 minutes for Bitcoin. If your casino supports it, LTC via GMO Coin provides the fastest, cheapest withdrawal path — zero fees and under 30 minutes total. For larger amounts, Bitcoin remains the most liquid option with the tightest spreads on Japanese exchanges.
Tax Considerations
Converting crypto to JPY creates a taxable event in Japan. Keep records of your casino deposits, withdrawals, and conversion rates. Net winnings exceeding ¥500,000 per year must be reported as temporary income (一時所得). Consider using crypto tax software to track your transactions automatically.
Common Issues and Solutions
If your withdrawal is delayed, check the blockchain explorer to verify the transaction status. Ensure you selected the correct network (e.g., Bitcoin mainnet, not Lightning Network) when withdrawing from the casino. If funds do not appear after 1 hour for BTC, contact the casino's support team.
