Rosen will conduct its first POS-linked stablecoin test in Japan to test JPYC

Japanese convenience store giant Rosen will pilot JPYC stablecoin payments in early August.

Japanese convenience store operator Rosen plans to launch a pilot in early August to accept payments in yen-denominated stablecoin JPYC.

Pilot overview

Rosen will conduct a trial at a store in Tokyo to connect JPYC payments directly to its POS system. Customers need to scan the barcode in their mobile wallet, and HashPort will update the balance based on the verified transaction data. Japan's largest banks are also preparing to issue yen stablecoins, intensifying competition in regulated digital payment networks across the country.

The test will be conducted at Rosen's Takawa Gateway City store in Minato, Tokyo. Digital asset wallet provider HashPort will support payment systems and process balance changes related to purchases.

Rosen described the project as Japan's "first" stablecoin payment pilot directly connected to the POS system. This claim comes from the company and testing has not yet begun. Rosen has not announced a full-chain launch.

The company will decide whether to expand the scope of use after checking system stability and transaction speed. At the same time, Rosen will also assess whether the process is suitable for normal store operations and will not slow down customer checkouts or add extra burden to employees during peak hours.

How POS integrated payment works

Customers need to open a supported mobile wallet and display a barcode on their mobile phone. Rosen employees use the store's existing POS terminal to scan the barcode. Later, HashPort uses payment information to update the customer's JPYC balance. The entire process is completed within Rosen's current store system.

The POS connection will also allow Rosen to manage purchase details, including item quantities and payment times, in addition to regular sales data. The test will measure the reliability of the system connection and the time required for each payment.

Customers use stablecoins when checking out, but employees still need to complete the scanning operation through the normal sales terminal. Rosen can compare the stablecoin process to bank card and QR code payments, including processing steps, error handling, and the time required to complete each transaction.

JPYC enters the daily retail field

JPYC Inc. will start releasing JPYC on October 27, 2025. The token is pegged to the yen and uses yen deposits and Japanese government bonds as reserve assets. The stablecoin was initially free of transaction fees and was designed to support payments and transfers under Japan's regulatory framework.

Prior to the Rosen test, similar applications had been launched in small retail and service industries. Chibo, the Japanese restaurant operator Miyoyaki, began accepting JPYC payments in some stores in April. Dental clinics in Tokyo and Chiba also plan to introduce JPYC payments through HashPort.

The difference between Rosen's experiment is that it interfaces stablecoin payments directly with the POS systems of large retailers. According to reports, stablecoins may provide merchants with lower rates than bank card or QR code services, but Rosen has not announced specific rate data for this pilot.

Japan expands stablecoin regulatory activities

Japan's large banks are also preparing to launch yen stablecoin services. Mitsubishi UFJ Bank, Sumitomo Mitsui Banking Corporation and Mizuho Bank plan to launch actual transactions in fiscal year 2026 (ending March 2027). The banks have formed a committee to jointly develop unified rules on issuance, governance, systems and future participation.

In addition, the bank project is advanced based on corporate cross-border payment testing supported by the Financial Services Agency of Japan and Progmat blockchain infrastructure. Japan has also opened up regulatory access to foreign stablecoins. After obtaining approval from the Financial Services Office, Ripple and SBI launched a dollar-backed RLUSD through SBI VC Trade in June 2026.
