Three Major Banks Unite Around a Stablecoin

The banks announced the plan on June 10, 2026, and will establish a council to determine governance, legal structures, and technical requirements.

The proposed MUFG SMBC Mizuho stablecoin will use a trust-based structure, with a licensed trustee managing the assets backing the token. 

While the banks have not disclosed the blockchain network, token name, or launch date, they confirmed their goal of enabling real commercial transactions during fiscal year 2026.

What Is a Yen Stablecoin?

A yen stablecoin is a digital token designed to maintain a value equal to the Japanese yen. Unlike cryptocurrencies such as Bitcoin, which fluctuate in price, stablecoins are backed by reserves and intended to maintain a stable value.

Potential benefits of a Japan yen stablecoin include:

• Faster settlement
• Lower transaction costs
• Blockchain-based transfers
• Programmable payments
• Improved transaction transparency

However, stablecoins still carry operational, regulatory, and cybersecurity risks.

How the Trust Structure Works

Under the proposed model, yen reserves would be held as trust assets by a licensed trustee. When approved participants deposit yen, an equivalent amount of stablecoins can be issued. Tokens can later be redeemed for yen and removed from circulation.

This structure is designed to strengthen customer protection by separating reserve assets from the operating assets of participating institutions.

FSA Stablecoin Pilot Provided the Foundation

The project follows a November 2025 trial supported by Japan's Financial Services Agency (FSA).

The FSA stablecoin pilot was the first initiative selected under the regulator's Payment Innovation Project. Participants included MUFG, Mizuho, SMBC, Mitsubishi UFJ Trust and Banking Corporation, Mitsubishi Corporation, and Progmat.

The trial explored whether multiple banking groups could jointly issue interoperable stablecoins while complying with Japanese regulations. It also tested cross-border corporate payments and examined potential reductions in remittance costs and administrative burdens.

How Project Pax Relates to the Plan

The banks have also participated in Project Pax, a cross-border payment initiative led by Progmat and Datachain.

The Project Pax yen stablecoin concept focuses on using regulated stablecoins for international settlements while allowing businesses to continue using familiar banking interfaces. The project also explores interoperability between blockchain networks.

Although closely related, the banks have not confirmed that the new joint stablecoin will officially operate under the Project Pax brand.

Why Are the Banks Working Together?

A shared stablecoin could prevent fragmentation in Japan's digital payments market. Instead of separate tokens issued by each bank, customers could use a common payment instrument across institutions.

The Japanese megabanks stablecoin 2027 initiative may also expand to include additional financial institutions in the future.

Why Japan Wants a Yen Stablecoin

The global stablecoin market is dominated by U.S. dollar-backed tokens such as USDT and USDC. As stablecoins become increasingly important for payments and digital finance, Japan sees value in promoting yen-denominated alternatives.

A widely adopted yen stablecoin could:

• Reduce reliance on dollar stablecoins
• Lower foreign exchange costs
• Support cross-border business payments
• Strengthen the yen's role in digital markets

Japan's ruling Liberal Democratic Party has also encouraged broader use of yen stablecoins across Asia.

Potential Corporate Uses

The initial focus is expected to be business payments rather than consumer spending.

Possible applications include:

International Payments

Faster and potentially cheaper cross-border transfers.

Intra-Company Transfers

Simplified movement of funds between subsidiaries and headquarters.

Supplier Payments

Automated payments through smart contracts.

Digital Asset Settlement

Settlement for tokenized securities and other digital assets.

Treasury Management

More efficient movement and tracking of corporate funds.

Conclusion

Japan introduced a formal stablecoin framework in 2023 through amendments to the Payment Services Act.

Under current rules, stablecoins can be issued by regulated banks, trust companies, and certain licensed financial institutions. Issuers must maintain redemption rights and comply with customer protection and anti-money laundering requirements.

The planned stablecoin will operate within this regulated framework.
