Japan's 3 mega banks just wrapped up live testing on a joint yen stablecoin for cross-border rails.

Mitsubishi UFJ, Mizuho, Sumitomo Mitsui ran the trial July 17-23, 2026. They verified issuance, transfer, redemption—using real payments between Mitsubishi Corp's Japan and overseas offices.

Key structure:
• All 3 banks co-commission issuance
• Mitsubishi UFJ Trust acts as trustee
• Stablecoin = specified trust beneficiary right under Japan's Payment Services Act
• Backed 1:1 by bank deposits
• No preset circulation cap—designed for scale across verified customers

They tested AML/CTF compliance, multi-issuer coordination, wallet infra, and user safeguards. Trial confirmed the joint model works and system is safe + reliable.

Next phase: governance, cybersecurity, regulatory sign-off before commercial launch (target: fiscal 2026).

Japan isn't just watching stablecoins from the sidelines. They're building institutional-grade on-chain payment rails with the backing of the country's largest banks and the FSA.

This is how TradFi enters crypto—quietly, methodically, and with regulatory blessing.
