Toshiba and 25 other firms join Japan’s six-month EJPY stablecoin trial on Japan Open Chain

Toshiba and 25 other Japanese companies have begun testing the EJPY stablecoin in a six-month program launched by the Japan Blockchain Foundation, exploring whether the yen-denominated token can handle everything from business settlements to cross-border remittances.

The trial, running through February 2027, gives participants access to EJPY test tokens and the Japan Open Chain network, but the foundation stresses that joining carries no commitment to actually issue or commercialize the stablecoin.

EJPY stablecoin moves from development to real-world testing

The latest initiative represents a significant change in the development of the EJPY stablecoin.

Rather than focusing solely on token issuance, Japan Blockchain Foundation is asking participating organizations to identify specific business problems that stablecoins could potentially solve. Those ideas will then be developed into use cases and subjected to technical testing.

The areas under consideration include domestic payments and remittances, cross-border transactions, business-to-business payments, digital-asset settlement and Web3 services. The program will also examine applications involving real-world assets and security tokens, as well as payments connected to local governments and regional economies.

Japan Blockchain Foundation said the objective is to move from proof of concept toward eventual social implementation.

That does not mean every participant will launch a stablecoin product.

The foundation explicitly states that participation is not a commitment by any company to issue, handle or commercialize a stablecoin. Instead, the six-month program is designed to determine whether proposed applications are technically and commercially viable.

Participants will receive education on stablecoin regulations, market developments and existing use cases. They can also receive individual consultations covering business models and system design.

Technical support will include EJPY test coins and wallets compatible with Japan Open Chain, giving participating companies an environment in which transactions can be tested before any commercial deployment is considered.

Japan Open Chain becomes the backbone of EJPY testing

The EJPY stablecoin is being developed as a trust-type Japanese yen stablecoin with Japan Open Chain at the center of its issuance and circulation strategy.

Japan Open Chain is an Ethereum-compatible public Layer 1 blockchain operated through a consortium of Japanese companies. Japan Blockchain Foundation has positioned the network as infrastructure for enterprise blockchain applications, including stablecoins and tokenized assets.

The foundation announced in May that it had formally decided to issue EJPY on Japan Open Chain and Ethereum after making progress on the trust-based structure. At the time, it said discussions were continuing around issuance, redemption, management of trust assets, system requirements and legal and regulatory compliance.

The planned token is intended to generate transactions based on actual business demand on Japan Open Chain.

Japan Blockchain Foundation has identified business-to-business settlements, digital-asset payments, remittances and Web3 payments among the potential applications.

The foundation is also considering multichain compatibility. That could eventually allow the token to operate across multiple blockchain environments rather than remaining tied exclusively to Japan Open Chain.

This infrastructure strategy gives the current trial a broader purpose. The organization is not simply testing whether a digital yen representation can move between wallets. It is testing whether a blockchain network can support recurring economic activity involving businesses, financial institutions and government entities.

EJPY enters Japan’s expanding stablecoin market

The EJPY stablecoin is entering an increasingly competitive Japanese market.

Japan has already established a regulatory framework for stablecoins, and companies are now exploring different models for issuing and using yen-denominated digital money. JPYC, for example, has developed a regulated yen stablecoin under Japan’s electronic payment instrument framework.

Other financial institutions are also pursuing stablecoin infrastructure. Japan’s major banks, including MUFG Bank, Sumitomo Mitsui Banking Corporation and Mizuho Bank, have been working on stablecoin-related initiatives as financial institutions examine blockchain-based settlement and payment systems.

The development of EJPY therefore comes as Japanese companies increasingly test whether stablecoins can move beyond cryptocurrency trading and into mainstream financial infrastructure.

That shift is visible across several parts of the economy, including retail payments, corporate settlements, tokenized assets and cross-border transfers.

For the Japan Blockchain Foundation, the challenge is now to demonstrate that its proposed token can support those applications in practice.

Six-month EJPY test could shape Japan’s stablecoin future

The six-month program gives the EJPY stablecoin its first broad testing environment involving companies with different operational requirements.

A technology company may examine blockchain-based settlement differently from a financial institution, retailer or local government. By allowing participants to develop use cases around their own business needs, the foundation expects to gather evidence on where stablecoins can provide practical value.

The program is free for participants and is scheduled to run through February 2027.

The outcome will not automatically determine whether EJPY becomes a commercial payment instrument. The foundation still has work to complete around issuance, redemption, the trust structure, legal compliance and supporting infrastructure.

However, the current testing period could provide a critical layer of evidence before those decisions are made.

The foundation’s stated goal is to use the results to develop services and systems around EJPY and Japan Open Chain and ultimately establish the network as infrastructure capable of supporting actual value transfers.

With Toshiba among the participating organizations and 10 additional participants yet to be publicly disclosed, Japan’s latest stablecoin experiment brings a broader group of potential users into the development process.

For EJPY, the next six months will therefore be less about announcing another yen-denominated token and more about answering a practical question: can stablecoins become useful infrastructure for the everyday payments, settlements and digital transactions of Japanese businesses?
