Welcome to Asia Pacific Morning Brief. An important digest of overnight cryptographic development that shapes regional markets and global sentiment. Grab some green tea and look at this space.
South Korea’s Coupang has partnered with Tempo blockchain to pay for potential Stablecoin, but Japan has introduced the first Stablecoin credit card repayments. These developments show an increase in mainstream crypto adoption across Asia’s largest economy.
Coupang’s blockchain experiment
Korean e-commerce giant Coupeng joined Tempo Blockchain as its first partner. Tempo is a Layer-1 blockchain developed by the US Fintech Stripe and the Crypto VC paradigm. The platform specializes in stubcoins and real-world payments.
This informs Coupang’s first disclosed blockchain venture, the adoption of potential Stablecoin. In fact, global e-commerce leaders such as Amazon and Shopify are already exploring similar technologies. Industry observers see this as a reflection of Coupang’s willingness to embrace blockchain innovation.
With Stablecoin integration, Coupang can save hundreds of millions of wins a year. This technology allows for immediate 24-hour transfers and reduces forex risk. However, regulatory uncertainty regarding South Korea’s stubcoin remains a major obstacle.
Market experts hope for faster blockchain adoption if domestic stubcoin regulations progress. The pending law will allow WON-controlled stubcoins by early 2026, allowing Coupang to expand access to payment data and growth opportunities for its ecosystem.
Stablecoin credit card innovation in Japan
JPYC Corporation has announced Japan’s first credit card to accept Stablecoin payments for the settlement. Nudge Corporation’s “Nudge Card” will accept Stablecoin JPYC, which has been supported by Japanese yen for repayment, starting October 2025. As a result, the service will allow JPYC to repay purchases from over 150 million visa merchants worldwide.
The system will initially target a limited number of users with NFT experiences and support polygon blockchains. This involves existing repayment methods, such as bank transfers and convenience store payments. This development represents an increasing acceptance of blockchain-based financial services in mainstream Japanese commercial transactions.
