Lawson and Netstars push Japan’s stablecoin payments story from pilot theory into live merchant rails

Japan’s stablecoin market moved closer to real consumer checkout usage on July 13, with two parallel announcements that matter more together than they do in isolation. HashPort said it signed a basic agreement with Lawson and KDDI to begin an August technical proof of concept for yen stablecoin payments at Lawson’s Takanawa Gateway City store in Tokyo. On the same day, payments company Netstars said it had formally launched Stablecoin Pay, a merchant service designed to let Japanese businesses accept multiple stablecoins while continuing to manage pricing, records and settlement in yen. Taken together, the developments suggest that Japan’s stablecoin conversation is starting to migrate from legal architecture and conference panels toward retail integration, merchant operations and payment acceptance at the point of sale.

The Lawson initiative is notable because it is aimed at the exact operational layer where many digital-asset payment concepts tend to break down. HashPort said the pilot will use its non-custodial HashPort Wallet on the customer side and its HashPort Wallet for Biz product on the merchant side, allowing the store to process stablecoin payments through existing point-of-sale flows without requiring the retailer to open and manage its own crypto wallet. The companies said the August test will focus on checkout procedures, systems integration, payment-processing speed and wallet usability before broader expansion is considered. That framing matters: the announcement is less about a symbolic crypto acceptance headline and more about whether stablecoin payments can fit inside the routines of a high-frequency retail environment with minimal extra burden on staff and infrastructure.

HashPort’s own release also ties the trial to a broader shift in Japan’s regulatory and market backdrop. The company pointed to the revised Payment Services Act framework that took effect in 2023, which has gradually created the conditions for yen-linked stablecoins to be issued and circulated under a clearer legal structure. Japan has spent the last several years building a more formal approach to digital payments, tokenized value and regulated issuance than many larger markets, but that policy groundwork only becomes commercially meaningful once payment acceptance products can operate inside everyday merchant channels. A convenience-store environment is especially relevant here because it represents a dense, routine, real-world transaction setting rather than a controlled crypto-native use case.

Netstars’ launch adds a second, equally important layer: merchant distribution. In its July 13 release, the company said Stablecoin Pay is the first service in Japan built for stores to introduce and operate multiple stablecoin payment options through a single application process. At launch, Netstars said the service supports USDC, USDT and the yen-denominated JPYC, initially across Solana and Polygon, with MetaMask as the supported wallet. The company set the merchant fee at 0.98% and said merchants in most cases can use existing payment terminals rather than installing new dedicated hardware. Netstars also emphasized that merchants can keep product pricing, sales management and reconciliation in yen even when customers pay with dollar-denominated stablecoins, reducing one of the biggest operational frictions for non-crypto businesses considering digital-asset acceptance.

That launch did not appear out of nowhere. Netstars said it had already run proof-of-concept work using USDC at Haneda Airport between January and February and later at a trading-card specialty store in Himeji beginning in April. Those earlier experiments gave the company a way to test system reliability, operating procedures and the customer payment experience before opening the product to a wider merchant base. In other words, the July 13 announcement was not just a new press cycle around stablecoins; it was a commercialization step built on prior transaction testing. For RWA and stablecoin watchers, that distinction matters because the strongest payment stories are usually the ones that move from sandbox pilots into repeatable merchant onboarding and standardized back-office handling.

The overlap between the Lawson and Netstars announcements also says something about where Japan’s next stablecoin competition may emerge. The market is no longer defined only by who can issue a compliant token or secure regulatory comfort. It is increasingly about who controls distribution, wallet usability, merchant software integration, payment routing and settlement abstraction. If customers can pay in stablecoins while merchants still think in yen, then the user experience starts to resemble conventional digital payments rather than crypto experimentation. That is the threshold at which stablecoins become infrastructure instead of novelty, and it is where payment networks, telecom groups, wallet providers and retailers all start competing to own the customer and merchant relationship.

There are still obvious limits to keep in view. Lawson’s project is explicitly a technical proof of concept, not a nationwide rollout, and Netstars’ current wallet and chain support is still narrow relative to what a mature retail network would require. Consumer demand for paying at convenience stores with stablecoins also remains unproven at scale, especially when Japan already has deep card, QR and mobile payment penetration. But these announcements qualify as meaningful progress because they are tackling the actual deployment constraints: compliance-ready structure, merchant acceptance software, wallet flows, settlement handling and store-level operations. If Japan can make those pieces work in ordinary retail settings, it will have done more than launch another pilot. It will have shown how stablecoins can be embedded into mainstream payment rails without forcing merchants to become crypto operators.
