Digital Garage Commercializes Stablecoin Payment Platform "DG SPS" to Drive Next-Gen Infrastructure in Japan

Digital Garage (TSE Prime: 4819) announced the commercial launch of its "DG Stablecoin Payment Service" (DG SPS), a specialized payment infrastructure designed to integrate stablecoin transactions into Japan's existing merchant and payment network.

The system will initially be deployed to major payment service providers, including JCB—which operates an international card network reaching 72 million merchants—and Digital Garage's subsidiary DG Financial Technology (DGFT).

DG SPS enables payment processors to offer stablecoin acceptance to merchants via a single API connection, eliminating the need for merchants to alter their existing point-of-sale (POS) systems or make extensive infrastructure investments.

The initiative aims to address operational complexities, non-standard system integrations, and multi-chain compatibility issues that have historically slowed stablecoin adoption among Japanese merchants. Key aspects of the deployment include:

• Supported Currencies and Blockchains: Launches initially with USDC payments on the Base blockchain network. Plans are in place to expand coverage to Japanese yen-pegged stablecoins (such as JPYC), alongside additional major networks including Ethereum and Polygon.
  
• Target Markets: Seeks to streamline transactions for inbound tourists in physical retail and reduce friction in cross-border e-commerce by bypassing traditional foreign exchange hurdles.
  
• Autonomous AI Commerce Capabilities: Integrates the x402 protocol (developed by the x402 Foundation) to support agentic commerce, preparing the infrastructure to handle autonomous payments initiated by AI agents alongside human transactions.

The commercial launch builds upon pilot testing initiated in early 2026 alongside JCB and Resona Holdings, which examined operational and technical factors for physical store integration. Digital Garage plans to further scale DG SPS across domestic financial networks to establish stablecoins as a core layer for next-generation payment infrastructure.
