立即购买 Sui

Japanese bank transfer and Visa/Mastercard card payments are available for JPY-denominated SUI purchases via Banxa and Mercuryo. Bank transfers are widely accessible and typically carry lower fees; card payments offer faster execution. Some Japanese-issued cards may restrict overseas crypto purchases — contact your card issuer if a payment is declined.

The FSA licenses crypto exchanges under the Payment Services Act, requiring strict KYC, customer asset segregation, and security standards. SUI is recognised as a crypto-asset under Japanese law. Gains from SUI are classified as miscellaneous income (雑所得) and taxed at progressive rates reaching up to approximately 55% combined. Staking rewards are also treated as miscellaneous income in the year received.

Sui's sub-second finality and object-centric parallel execution address performance limitations that Japanese DeFi users experience on Ethereum. SUI staking at approximately 4–6% APY in a USD-denominated asset represents a dramatically higher potential yield than Japanese bank savings accounts, which remain well below 1% even after the BoJ's tentative rate rises. Japan's retail crypto culture is among the deepest globally, and Move-language L1 platforms have attracted developer and investor attention.

Stake SUI for approximately 4–6% APY with no lockup via Sui Wallet; use Cetus DEX and Navi Protocol for DeFi activity; or trade SUI perpetuals on BitMEX. Japanese investors should maintain detailed records of acquisition cost, disposal proceeds, and staking reward receipts for NTA miscellaneous income reporting — Japan's progressive tax rates make accurate record-keeping especially important.
