A consortium of major Japanese financial institutions has launched a proof-of-concept (PoC) trial to explore using blockchain technology for managing Japanese Government Bonds (JGBs) as collateral. The group includes Mizuho Financial Group, Inc., Nomura Holdings, Inc., Japan Securities Clearing Corporation (JSCC), and Digital Asset Holdings, LLC, and will leverage the Canton Network for the initiative.
The primary goal of the trial is to verify the legal and practical feasibility of transferring JGBs on-chain while ensuring compliance with Japan's existing legal frameworks, specifically the Act on Book-Entry Transfer of Corporate Bonds and Shares and the Financial Instruments and Exchange Act. A core focus is maintaining the legal status of the bonds when digitized. The PoC will also test the integration of current market systems with the Canton Network to enable real-time, 24/7, and cross-border collateral movement, aiming to reduce administrative burdens in collateral management.
The project has received regulatory backing, having been selected earlier this year by Japan's Financial Services Agency (FSA) under its Payment Innovation Project within the FinTech PoC Hub. This initiative mirrors similar global efforts, such as a December 2025 pilot on the Canton Network that involved tokenized U.S. Treasuries and institutions like Bank of America and Société Générale, which demonstrated the potential for reusing government securities as collateral across different counterparties on-chain.
While the trial represents a significant step in Japan's institutional digital asset push, the companies involved have stated that findings will inform future discussions, and no timeline has been set for a commercial rollout.
