Lawson and Netstars push Japan stablecoin payments toward repeatable retail rollout
Lawson will test yen stablecoin checkout in Tokyo in August as Netstars opens Stablecoin Pay to merchants at a 0.98% fee.
Japan’s stablecoin payment rails moved closer to mainstream retail use as Lawson lined up an in-store yen-stablecoin checkout test in Tokyo for August. Separately, payments firm Netstars launched a merchant product that accepts USDC, USDT and JPYC while keeping pricing and settlement in yen.
Key Takeaways
- Lawson plans an August in-store test of yen-denominated stablecoin payments at its Takanawa Gateway City location in Tokyo.
- HashPort has an agreement with Lawson and KDDI to run the pilot and evaluate integration, checkout operations, processing time, and wallet usability.
- Customers will pay from HashPort’s non-custodial wallet while the store processes the transaction through a HashPort point-of-sale setup without managing crypto wallets.
- Netstars opened Stablecoin Pay applications for merchants, launching with USDC, USDT and JPYC on Solana and Polygon via MetaMask and a 0.98% merchant fee.
Lawson’s August Tokyo Pilot Puts Yen Stablecoins Into a Convenience-Store Checkout
Lawson plans to test yen-denominated stablecoin payments at a Tokyo location in August, with the explicit goal of seeing whether stablecoin payments can fit inside a standard convenience-store checkout flow.
HashPort said it signed an agreement with Lawson and telecom group KDDI to conduct the trial at the Lawson Takanawa Gateway City store. The pilot is framed as an integration exercise more than a marketing stunt, with the companies set to assess integration requirements, checkout operations, payment processing times, and wallet usability before considering broader applications.
One key detail remains unresolved. The specific yen-denominated stablecoin to be used in the August test has not been named.
Stablecoin Pay: Netstars Opens Merchant Acceptance for USDC, USDT and JPYC
Netstars launched “Stablecoin Pay” and opened applications for merchants that want to accept stablecoins. At launch, the service supports USDC, USDT, and yen-denominated JPYC, using the Solana and Polygon networks, with MetaMask as the supported wallet.
Netstars set the merchant payment fee at 0.98% and said it plans to add more wallets and blockchains. The operational pitch is straightforward: merchants can generally use existing payment terminals “in most cases” and keep product pricing, sales records, and settlement in yen even when customers pay with dollar-denominated stablecoins. That structure positions Stablecoin Pay as a “no-crypto-balance-sheet” option, where the merchant does not need to hold crypto or manage exchange rates to participate.
The launch follows Netstars’ earlier USDC payment trials at Tokyo’s Haneda Airport from January to February 2026 and at a trading-card store in Himeji in April 2026, shifting the effort from limited-location experiments into a merchant-facing distribution channel with defined rails.
How the Flow Works: Non-Custodial Wallet for Users, POS Processing for the Store
The Lawson pilot is designed to minimize merchant operational friction. Participants will use HashPort’s non-custodial wallet, meaning the user controls the private keys, while the store processes payments through HashPort’s point-of-sale system without needing to open or manage crypto wallets.
That division of labor matters for retail. The test is not just whether a yen-denominated stablecoin can clear, but whether the flow can survive real checkout constraints like speed, staff training, and reconciliation inside existing retail infrastructure.
Catalysts for Solana/Polygon Payment Narratives in Japan
The near-term catalyst is August itself: confirmation of the pilot’s exact start date, duration, and scale, plus disclosure of which yen-denominated stablecoin is used at Lawson’s Takanawa Gateway City store.
On the Netstars side, rollout signals will come from whether wallet support expands beyond MetaMask and whether additional blockchains are added beyond Solana and Polygon. Merchant adoption indicators matter more than announcements, including whether merchants can actually use existing payment terminals “in most cases” and whether yen settlement remains standard across supported stablecoins.
The regulatory backdrop is already in place. Japan’s stablecoin framework took effect June 1, 2023 via amendments to the Payment Services Act and related laws, requiring intermediaries to register with the Financial Services Agency. USDC distribution was approved in March 2025, and JPYC registered in August 2025 before launching in October. Any new FSA-related approvals or registrations tied to stablecoin intermediaries would be a concrete signal that the rails are broadening.
What This Means for Stablecoin Adoption Trades
I treat these as plumbing stories, not hype cycles. The Lawson pilot is explicitly testing whether stablecoins can live inside a normal convenience-store checkout without forcing the merchant to touch wallet ops, and that’s the right design if the goal is scale.
The threshold that matters is whether Netstars can turn “merchant applications open” into repeatable deployment with yen pricing, yen settlement, and minimal terminal changes. If that holds, the setup starts to look structural rather than narrative-driven, because it reduces the two frictions that kill retail crypto payments: operational burden and balance-sheet exposure.
