JPYC (Japan JPY Coin) is Japan's first widely available Japanese yen stablecoin, pegged 1:1 to the Japanese yen. Unlike USDT or USDC which are dollar-denominated, JPYC enables Japanese users to hold yen value on-chain and participate in DeFi ecosystems without the currency risk associated with USD stablecoins. This review explains what JPYC is, how it works, and who it is for.
What is JPYC?
JPYC is a JPY-pegged stablecoin issued by JPYC Inc. (formerly Japan Crypto Asset Exchange Association member). It operates as a prepaid payment instrument under Japan's Payment Services Act — the same legal framework that governs gift cards and e-money. This regulatory classification allows JPYC to avoid the strict Virtual Currency Act requirements that govern exchanges like bitFlyer and Coincheck.
JPYC launched in January 2021 on the Ethereum blockchain as an ERC-20 token. Since then, it has expanded to multiple chains including Polygon, Avalanche, Gnosis Chain, and Astar Network. Each JPYC token is fully backed 1:1 by Japanese yen held in custody by the issuer.

How to Buy JPYC
JPYC can be purchased directly from JPYC Inc.'s official website using bank transfer. The process is straightforward:
- Create an account on the JPYC website and complete KYC verification.
- Connect your Ethereum-compatible wallet (MetaMask, etc.).
- Transfer JPY via bank transfer to JPYC Inc.'s designated account.
- JPYC tokens are issued to your wallet at a 1:1 ratio (minus a small issuance fee).
JPYC can also be obtained through secondary markets — it is listed on Uniswap, Curve Finance, and several other DEXs. Secondary market prices may vary slightly from the 1:1 peg depending on liquidity conditions.
Use Cases
DeFi without USD Exposure
Japanese DeFi users who want to participate in yield farming or liquidity provision without taking on USD/JPY currency risk can use JPYC to remain denominated in yen. JPYC/USDC pools on Curve, for example, allow Japanese users to provide stablecoin liquidity while keeping their base currency in JPY.
NFT Purchases
Several Japanese NFT marketplaces support JPYC as a payment method, allowing creators and buyers to transact in yen-denominated value on-chain. This removes the friction of converting JPY to ETH for NFT purchases.
Corporate Treasury and B2B Payments
JPYC Inc. has been working with Japanese companies on using JPYC for B2B settlement and corporate treasury management. Blockchain-based yen transfers can offer faster settlement than traditional bank transfers, particularly for cross-border transactions involving Japan.
On-Chain Remittances
For sending yen value internationally via blockchain, JPYC offers a way to transfer Japanese yen equivalent without using the traditional SWIFT banking system. The recipient can then redeem JPYC through JPYC Inc. or convert via DEX.

Summary
JPYC fills an important gap in Japan's crypto ecosystem — it allows yen holders to participate in DeFi and on-chain commerce without converting to a foreign-currency stablecoin. For Japanese users who are bearish on USD or simply want to remain in JPY terms, JPYC is the natural on-chain solution.
However, JPYC's ecosystem is still developing. DeFi liquidity is limited compared to USDT or USDC, and the redemption process involves manual steps. As Japan's regulatory environment for stablecoins matures under the revised Payment Services Act, JPYC is well-positioned to grow — but today it remains a niche tool for Japan-focused DeFi users rather than a general-purpose stablecoin.
