Japan Post Bank to Launch Digital Yen (DCJPY) Backed by Deposits by 2026

Japan Post Bank has announced that it will issue a digital yen by the end of fiscal 2026, introducing a blockchain-based currency designed to make financial transactions faster, more transparent, and more convenient for both individual and corporate clients.

The new digital currency, called DCJPY, will be developed in partnership with DeCurret DCP, a Tokyo-based fintech subsidiary of Internet Initiative Japan. Japan Post Bank, which manages nearly 190 trillion yen ($1.29 trillion) in deposits and counts the Japanese government among its shareholders, is positioning DCJPY as a regulated, deposit-backed alternative to traditional stablecoins.

How DCJPY Will Work

• 1:1 Backed by Yen: Each DCJPY will be equivalent to ¥1 and fully backed by fiat deposits.
• Linked to Savings Accounts: A depositor’s DCJPY account will be directly connected to their Japan Post Bank savings account.
• App-Based Conversions: Customers can seamlessly convert yen into DCJPY and back through a dedicated app.
• Deposit Insurance Protection: Unlike stablecoins, DCJPY will fall under Japan’s deposit insurance system, ensuring regulatory oversight and depositor security.

Use Cases and Benefits

DCJPY will enable instant settlement of digital securities and blockchain-powered assets, while also reducing transaction costs compared to conventional methods. By the end of fiscal 2026, the Bank plans to expand use cases, allowing customers to purchase:

• Small-lot assets such as real estate and corporate bonds
• NFTs (nonfungible tokens) and other digital financial products

The bank also sees potential for local governments to use DCJPY to distribute subsidies and welfare benefits efficiently, further accelerating adoption.

A Japan Post Bank official commented:
“We will be able to provide a new payment method and develop the market.”

Blockchain Integration

The new digital yen will leverage blockchain technology for security, transparency, and real-time settlement. This innovation places Japan Post Bank at the forefront of the country’s growing tokenized deposit currency ecosystem.

The 2026 timeline allow the Bank to develop necessary infrastructure and regulatory approvals for what would become one of the world's largest tokenized deposit programs by customer base and asset backing.
