Japan's third-largest convenience store chain, Lawson, will begin accepting payments in JPYC, a yen-pegged stablecoin, at a single Tokyo store starting in August 2026. With 14,697 domestic stores and ¥3.02 trillion (approximately $20.3 billion) in annual net sales, Lawson's participation signals meaningful institutional interest even at the scale of a single-location pilot. The trial is being organised by KDDI, Japan's second-largest telecommunications operator, in partnership with crypto wallet firm HashPort, which has prior live deployment experience through its wallet application at the Osaka World Expo. The pilot is restricted to employees of the three partner companies at launch and will run at the Lawson Takanawa Gateway City location.

Lawson characterised the pilot, as reported by crypto.news, as what the company claims is Japan's first stablecoin payment trial tied directly to a point-of-sale (POS) system at a major retailer. That framing reflects the specific integration method being tested: customers display a barcode in a mobile wallet app, a store cashier scans it using existing POS hardware, and HashPort then updates the customer's JPYC balance on-chain. No new payment terminals are required.

What JPYC Is and Why It Matters Here

JPYC (JPY Coin) is a multi-chain token pegged to the Japanese yen at a one-to-one ratio. It runs on Ethereum, Polygon, Avalanche, and the Kaia network. JPYC Inc. holds a license as a Type II Fund Transfer Service Provider; the company is cited as Japan's first formally registered yen stablecoin under the country's Payment Services Act framework. Relevant regulatory milestones include a licensing date of August 2025 and the full implementation of the 2025 Payment Services Act Amendment in June 2026. Reserves are held in yen-denominated bank deposits and Japanese Government Bonds, a composition consistent with the updated reserve rules described in the regulatory section below.

Current on-chain data reflects the instrument's design as a settlement tool rather than a traded asset. JPYC's 24-hour trading volume sits near $68, with a total circulating supply of over 2 billion JPYC, representing over 2 billion yen in circulation. Of the $137 million in total volume recorded since October 2025, Polygon accounts for approximately $90.4 million, or 66 percent of all activity. The Ethereum contract address is 0x431d5dff03120afa4bdf332c61a6e1766ef37bdb.

KDDI's Broader Web3 Push

The Lawson trial is one piece of a larger infrastructure play by KDDI. The company holds roughly a 20 percent equity stake in HashPort and separately invested $65 million for a 14.9 percent stake in Coincheck Group in May 2026. KDDI is also building out a joint venture called au Coincheck Digital Assets, expected to launch a digital asset wallet in summer 2026.

The longer-term ambition involves KDDI's Ponta loyalty programme, which has 120 million members. According to reporting by Nikkei Asia, KDDI and HashPort are reported to intend to allow Ponta users to convert accumulated points into stablecoins through a wallet app, with those balances then rechargeable into au PAY, KDDI's mainstream cashless payment service used by roughly 39 million people. The Lawson pilot is an early practical test of the payment-receiving side of that integrated model.

No direct statements from Lawson, KDDI, or JPYC Inc. were publicly available at the time of publication. The corporate plans described above draw on indirect reporting by Nikkei Asia. Verse Press is seeking official comment.

Regulatory Framework Underpins the Model

Japan's stablecoin rules underwent a significant overhaul under the 2025 Payment Services Act Amendment, which took full effect in June 2026. The law classifies stablecoins redeemable at face value for fiat currency as "Electronic Payment Instruments" and restricts issuance to banks, trust companies, or licensed funds transfer providers. A separate licensing category governs distribution. This dual-track structure keeps issuance tightly controlled while allowing third parties to handle distribution separately.

The framework also loosened reserve requirements: issuers may now hold up to 50 percent of backing in short-term Japanese Government Bonds with maturities of three months or less, replacing an earlier rule requiring 100 percent demand deposits. JPYC's current reserve composition, which includes both bank deposits and Japanese Government Bonds, is consistent with this updated standard. Foreign stablecoins gained a formal pathway into the Japanese market in June 2026, with USDC now available through SBI VC Trade. USDT remains unavailable on licensed Japanese platforms.

Relevance for Markets Outside Japan

The Lawson pilot carries practical lessons for markets across South Asia and Africa, where telco-led digital payment infrastructure is well established but stablecoin integration remains limited. South Asia is the fastest-growing region for crypto adoption through mid-2025, recording an 80 percent increase in stablecoin-driven volumes over that period. India presents the most directly comparable infrastructure context: its Unified Payments Interface has achieved mass-market scale, even as the Reserve Bank of India has maintained a cautious stance toward private digital currencies. Elsewhere in the region, mobile money operators including bKash in Bangladesh and JazzCash in Pakistan have been identified as potential candidates for similar stablecoin payment architectures. The KDDI model, in which a telecom acquires stakes in both a wallet operator and a crypto exchange to build a connected loyalty-to-payment infrastructure, maps onto what those operators could construct with a locally licensed stablecoin. South Asia's remittance corridors, which handle roughly $200 billion annually, represent a significant potential use case.

In East and West Africa, M-Pesa, MTN MoMo, and Airtel Money already use QR-based POS flows similar to the barcode method HashPort is deploying at Lawson. The barcode approach requires no hardware upgrades at the merchant level, which matters in markets where terminal replacement is a major adoption barrier.

The pilot's scale is deliberately narrow. The August trial will determine whether Lawson and KDDI move to expand the programme beyond the initial employee cohort.
