Japan's Largest Card Network Taps Circle to Bring USDC to 40 Million Merchants

JCB signs stablecoin agreement with Circle

JCB, Japan's largest card network, signed a memorandum of understanding (MOU) with Circle on 14 July 2026 to explore stablecoin payments. The agreement centers on USDC, the dollar-backed stablecoin issued by Circle. Both companies framed the deal as a step toward stablecoin adoption in Japan's cashless economy. The MOU is a non-binding agreement to study joint use cases, not a signed commercial contract. It sets a framework for the two firms to test how a regulated stablecoin can move money across their networks.

"Stablecoins are gaining attention around the world as a foundation for creating a new ecosystem in cashless societies, given their high level of convenience, and the market is expanding rapidly.", 14 July 2026. — JCB and Circle, joint statement

Deal targets transfers and merchant payments

The MOU sets out two areas of collaboration. The first is cross-border treasury and payments. The second is stablecoin-enabled payments at merchants in Japan. JCB and Circle plan to study how USDC can cut remittance costs and ease currency exchange for inbound tourists. The companies also want to speed up settlement between parties in different countries. Traditional cross-border transfers can take days and pass through several banks, while a stablecoin transfer settles on a public blockchain in minutes. Lower settlement costs could benefit the many tourists who spend in Japan each year, one of the goals both firms named.

JCB brings a large merchant network

According to CoinDesk, JCB serves about 140 million users and 40 million merchants worldwide. That reach gives the partnership a wide base for testing in-store stablecoin payments. International visitors to Japan are an early target group, since stablecoins can bypass the exchange fees tied to traditional card spending. CoinDesk also reported that stablecoin payments can sidestep the spending limits attached to conventional cards, which may help large or business purchases. For merchants, the appeal is faster access to funds and lower processing costs. The two companies have not named which merchants or regions will join the first tests.

Japan's rules opened the door to stablecoins

The partnership follows Japanese regulatory changes that allow broader stablecoin use, according to CoinDesk. Those rules give issuers and payment firms a legal path to settle transactions with stablecoins. Domestic momentum is building beyond this deal. CoinDesk reported that convenience-store chain Lawson plans to pilot JPYC, a yen-denominated stablecoin, from August 2026. Together, the moves show Japan's payment industry testing stablecoins for both retail and cross-border use.

USDC holds a market cap near $73 billion

USDC traded at $1.00 at the time of publication, with a market capitalization near $73 billion (CoinPaprika, 14 July 2026). That makes USDC the second-largest stablecoin by market value, behind Tether's USDT. Its scale gives JCB an established, dollar-pegged settlement asset for cross-border use. A large, liquid stablecoin lowers the risk that a transfer cannot be converted back to cash on demand.

Partnership starts with internal fund transfers

The companies plan to begin with a proof of concept for JCB's internal fund transfers. They expect to expand later to in-store payments for merchants and visitors. Separately, Circle and Nomura are targeting foreign-exchange settlement using stablecoins as early as 2027, according to CoinDesk. JCB and Circle described the current work as exploratory, with no firm launch date for a public product. The MOU does not disclose transaction volumes, fees, or a budget for the pilots.
