Sony Bank signed a memorandum of Mnemonics with JPYC to study the real-time conversion of the yen stablecoin, as Japan officially formalizes the legal framework for stablecoins from October 2025.
Sony Bank and JPYC Inc., the issuer of the stablecoin JPYC, have signed a memorandum of Mnemonics to study mechanisms that would allow customers to purchase the JPYC stablecoin, Peg to the Japanese yen, directly from their bank accounts in real time, eliminating the need for manual transfers through cryptocurrency exchanges.
Transactions will be conducted through the JPYC EX platform, requiring identity verification, while Sony Bank's Web3 subsidiary, BlockBloom, will play a central Vai in designing the connection between the banking system and the stablecoin infrastructure.
JPYC began issuing yen-backed stablecoins on October 27, 2025, under Japan's amended Payment Services Law, the official document recognizing stablecoins as electronic payment instruments. The Token are backed at a one-to-one ratio by Japanese bank deposits and government bonds.
Both sides emphasized that the agreement is currently in the exploratory phase, does not include the issuance of new stablecoins, and has no specific implementation roadmap. The real-time conversion feature is designed within a neutral framework, not limited to Sony Bank, to ensure scalability to other financial institutions.
Sony's ambition to expand into entertainment and the Sony ecosystem.
Beyond purely payment transactions, Sony Bank and JPYC stated they will explore integrating stablecoins with intellectual property assets in the entertainment sector, including music and video games, opening up potential use cases such as purchasing digital content and distributing rewards.
This approach reflects Sony's unique advantage over conventional banking partners, as the parent company owns a vast entertainment ecosystem that can become a natural channel for stablecoin consumption.
Sony Bank's move comes as JPYC recently announced plans to raise 1.78 billion yen, or approximately $12 million, in the first round of its Series B funding round, led by Asteria Corporation, to expand its systems and partnerships.
The involvement of a major branded bank like Sony Bank at this acceleration phase strengthens JPYC's position in the competition for domestic stablecoin issuance in Japan, as regulated financial institutions are gradually shifting from an exploratory approach to substantive integration at the deposit infrastructure level.
