Japan’s top three largest banks, Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Banking Corporation, and Mizuho Bank, Ltd, have announced plans to jointly launch a yen-backed stablecoin by March 2027.

 

In a recent press release, the three megabanks said plans were already in place for the trio to conduct actual commercial transactions using the stablecoin. This is not a test or pilot program but a real financial infrastructure enabling stablecoin-based payments.

 

As a major step toward this goal, the three megabanks signed a Memorandum of Understanding (MoU) to establish a voluntary joint council responsible for developing the stablecoin operational framework, including issuance infrastructure, systems, schemes, governance, and future collaboration with other institutions.

 

Together with the Financial Services Agency (FSA), Japan’s primary financial regulatory authority, the three banks conducted a FinTech Proof of Concept pilot program around November 2025. The goal of the pilot was to assess whether multiple banks could jointly issue the stablecoin while ensuring compliance with all regulatory, legal, and compliance standards.

 

The Mitsubishi UFJ Financial Group’s partnership with the two other megabanks comes shortly after Mitsubishi Corporation, an entity within the broader Mitsubishi Group, adopted JPMorgan’s Kinexys blockchain network for cash management for its global subsidiaries.

 

Just like Japan’s megabanks' collaboration to launch a stablecoin, other banks have made similar moves, notable among which is Qivalis, a consortium comprising 37 European banks that are collaborating to launch a stablecoin for the euro.

 

Stablecoins continue to grow rapidly, with many traditional financial institutions entering the sector. According to a recent report, stablecoin transaction volume exceeded 28 trillion dollars in the first quarter of this year, approaching the 33 trillion dollar annual transaction volume recorded in 2025. US dollar pegged stablecoins still make up a large share of the global stablecoin supply, representing about 97 percent of the total global stablecoin supply.
