Japan's Financial Services Agency approves first bank-issued stablecoin project | Traditional finance officially enters the digital currency system

I. Introduction: Japan's digital finance achieves a historic breakthrough

In October 2025, Japan's Financial Services Agency (FSA) officially approved the country's first stablecoin project issued by a commercial bank.
This marks Japan as the first major Asian economy to fully open up the issuance of bank-grade stablecoins under a fiat currency framework , and also symbolizes the deep integration of the traditional financial system with blockchain technology.

The project is led by Sumitomo Mitsui Trust Bank, and the token is named "JPY Token (JPYT)," which is pegged to the Japanese yen at a 1:1 ratio. Issuance and clearing are both carried out under the supervision of the FSA.
This move is seen as a major strategic turning point for Japan in the international competition for digital currencies.

II. Policy Background: From Prudent Regulation to Proactive Innovation

Japan became one of the first countries in the world to legislate on crypto assets as early as 2017, but its regulatory approach has been cautious for a long time, especially with strict restrictions on stablecoins.
The legal definition of stablecoins was not established until the passage of the Amendment to the Payment Services Law in 2022.

• It must be secured by legal tender;

• Only banks, trust companies, or fund transfer institutions may issue such securities.

• Investors are entitled to full redemption.

After three years of revisions, this system will finally be implemented in 2025.
An FSA official stated at a press conference: "We are not against innovation, but innovation must be based on trust and security."
This statement reflects a shift in Japan's regulatory approach from "risk prevention" to "building openness under rules".

III. Project Details: The Operating Mechanism of the JPYT Stablecoin

JPYT's design follows three principles: " asset segregation + audit traceability + bank custody ."

1. Asset segregation : The actual Japanese yen assets in the corresponding custodian account for JPYT purchased by users are placed in a regulated trust structure to prevent commingling of funds.

2. Real-time audit and supervision interface
   The system has a built-in automatic reporting module, allowing the FSA to view issuance volume, clearing flow, and abnormal transactions in real time.
   Meanwhile, the external audit firm issues a reserve audit report every quarter.

3. Cross-platform compatibility
   JPYT is based on an enterprise-grade blockchain network (jointly developed by Sumitomo Mitsui Trust and NEC Corporation) and supports interoperability across exchanges and institutions.

In terms of user experience, individuals or businesses can directly purchase or redeem JPYT through their bank accounts, with an interface no different from traditional online banking.

IV. Strategic Significance: Banks Become New Players in Digital Currency

The introduction of JPYT is seen as an important sign of the self-reform of the Japanese banking system.
For a long time, Japan's financial industry has faced problems such as slow deposit growth, low payment efficiency, and loss of young users.
By issuing stablecoins, banks can rebuild their competitive advantage in several areas:

1. Retain customer assets : Provide digital yen alternatives to prevent funds from flowing to crypto exchanges or external wallets.

2. Reduced payment costs : Inter-enterprise settlements can be completed instantly, without the need for intermediary banks.

3. Expanding into new business models : Integrating smart contracts to provide services such as supply chain finance, bill settlement, and payroll processing.

4. Enhancing international competitiveness : Paving the way for a future cross-border settlement system among China, Japan, South Korea, and ASEAN.

Industry experts point out: "Stablecoins are no longer just the domain of fintech companies; banks are the next real players."

V. Market Feedback: The Japanese capital market responded positively.

The Japanese financial market reacted enthusiastically after the project was approved.
Blockchain-related stocks on the Tokyo Stock Exchange rose by approximately 3% overall, among which:

• NEC rose 6.8%;

• SBI Holdings rose 4.5%;

• Shares of Sumitomo Mitsui Financial Group rose 3.9%.

The market generally believes that the FSA's approval means that the banking industry has been officially granted the right to issue digital assets , which will drive traditional financial institutions to accelerate their digital transformation.
The Japan Bankers Association stated that it will support more member banks in exploring technological pathways for stablecoins and tokenized deposits.

VI. International Comparison: The Uniqueness of the Japanese Model

Compared to other countries, Japan's regulatory approach has significant institutional differences:

Japan's choice of a "bank-centric" model aims to establish a regulatory template for stablecoins by leveraging its existing trust system and compliance structure.
This design helps protect depositors' interests while strengthening the government's control over the money supply.

VII. Financial Innovation: Not Parallel to Central Bank Digital Currency

It is worth noting that the Bank of Japan (BOJ) is advancing a feasibility study on the digital yen.
The official statement said that the JPYT issued by banks does not compete with the central bank's digital currency, but rather has a "complementary and coexisting" relationship.

• The digital yen will provide the public with a zero-risk payment infrastructure ;

• Bank stablecoins, on the other hand, are geared towards enterprises and cross-border clearing scenarios, undertaking the function of market-oriented innovation .

This "dual-track system" design makes Japan a potential candidate to become one of the world's first economies to implement a "central bank currency + commercial stablecoin dual-track system".

VIII. Regulatory Innovation: Risk Control and Responsibility Allocation

To ensure security, the FSA has simultaneously launched a new regulatory framework for stablecoins, encompassing five core mechanisms:

1. Dynamic reserve disclosure system : Issuers are required to disclose their reserve balance and redemption records daily.

2. The Investor Protection Fund will establish a "Stablecoin Trust Fund" to address extreme redemption risks.

3. Cross-chain transfer approval mechanism
   Cross-border transfers must undergo automated compliance checks to prevent capital flight.

4. Mandatory Cold Wallet Ratio : At least 50% of reserve assets must be stored in cold storage accounts.

5. Emergency Clause for Technical Incidents
   If the system is compromised, the bank may temporarily freeze the circulating supply on the blockchain to protect the rights and interests of token holders.

Experts commented that this regulatory approach is "both conservative and open," striking a balance between safety and innovation.

IX. Potential Impact: The regional financial landscape may be reshaped.

The launch of JPYT will have a series of strategic implications for Japan:

• Promoting a regional monetary digitalization alliance , Japan is expected to lead the establishment of an Asian version of the "Stablecoin Interoperability Network," connecting Singapore, South Korea, and Hong Kong.

• Promoting capital inflows
  The improved efficiency of stablecoin settlements will attract more international institutions to use yen assets.

• Enhance the internationalization of the yen . Enable broader cross-border applications through programmable stablecoins and increase the yen's usage in international payments.

• This could set a regulatory precedent , potentially leading to policy adjustments by South Korea, Taiwan, and ASEAN countries following the Japanese model and promoting regional regulatory coordination.

X. Conclusion: The "Digital Currency Revival" of Traditional Banks

From rejection to acceptance, from observation to implementation, Japan took eight years to institutionalize the adoption of digital currency.
The FSA's approval is not only an endorsement of the technology, but also a redefinition of the role of banks.
In the future digital finance landscape, banks will no longer be merely "passive adaptors," but will become the core driving force of the digital currency system.

The emergence of JPYT marked the beginning of a new era for the Japanese financial system.
It combines the traditional trust system with the transparency mechanism of blockchain, opening up a digital currency path that is different from the West.

As the chairman of Sumitomo Mitsui Trust Bank stated at the press conference:

"Our goal is not to replace money, but to make it more efficient and trustworthy."
