The Japan Securities Clearing Corporation (JSCC), a subsidiary of the Japan Exchange Group (JPX), announced on Monday its collaboration with Mizuho Financial Group, Nomura Holdings, and Digital Asset to initiate a proof of concept aimed at exploring the utilization of Japanese government bonds as digital collateral within the Canton Network.
This initiative will investigate whether Japanese Government Bonds (JGBs) can be effectively transferred and managed on-chain while preserving their legal standing in accordance with both the Book-Entry Transfer Act and the Financial Instruments and Exchange Act.
Additionally, this trial will assess if existing systems can be integrated with Canton’s blockchain framework to facilitate more advanced real-time collateral transactions around the clock, including scenarios involving cross-border applications.
The project was selected for support by Japan’s Financial Services Agency in February as part of its Payment Innovation Project under the FinTech PoC Hub, according to their announcement.
This trial brings one of the largest sovereign bond markets into discussions about enhancing efficiency in collateral movement across digital market infrastructures without infringing upon current legal and regulatory frameworks.
The participating companies noted that this trial is timely given the increasing adoption of digital assets not only in markets like the United States but also gaining traction in Japan. The results are anticipated to contribute valuable insights into how JGBs could be utilized within digital collateral frameworks; however, no specific timeline for commercial implementation has been disclosed yet.

Canton Broadens Government Bond Testing
A previous pilot conducted by Canton back in December 2025 involved tokenized US Treasuries being reused as real-time collateral among major dealers and market participants such as Bank of America and Société Générale.
This earlier testing underscored opportunities for reusing high-quality government securities on-chain among various participants. The new JGB initiative seeks to extend these concepts into Japan’s government bond sector.
In another development from February, HSBC’s Orion platform was appointed by the UK government to manage issuance for its Digital Gilt Instrument pilot within the Bank of England’s Digital Securities Sandbox while exploring distributed ledger technology applications for sovereign debt management.
Cointelegraph reached out to JSCC and Digital Asset seeking comments but had not received any feedback prior to publication time.
