Japan’s JSCC is exploring using government bonds as digital collateral on the blockchain

Japan’s clearing arm JSCC has begun testing whether government bonds can serve as digital collateral for blockchain infrastructure.
Summary
- JSCC launched a proof of concept with Mizuho, Nomura, and Digital Asset to test Japanese government bonds as on-chain collateral.
- The case will examine whether JGBs can be transferred digitally while remaining compliant with Japan’s existing legal framework.
- Testing will also focus on real-time and cross-border security applications as institutions test 24-hour blockchain-based residential systems.
According to an announcement on Monday from the Japan Securities Clearing Corporation, which is part of the Japan Exchange Group, the company has partnered with Mizuho Financial Group, Nomura Holdings, and Digital Asset to launch a proof of concept using Japanese Government bonds on the Canton Network.
The trial will examine whether Japanese Government bonds can be transferred and managed on-chain while still complying with the country’s Transfer of Papers Act and the Financial Instruments and Exchange Act.
Maintaining legal recognition remains at the core of the work, as any transition to a digital infrastructure must comply with existing frameworks that govern how bonds are issued, held, and transferred.
Participants will also explore whether current market systems can integrate with Canton’s blockchain stack to support real-time securities movements on a 24/7 basis, including cross-border.
Japan’s Financial Services Agency selected the project earlier this year under the Payment Innovation Project, which is part of the FinTech PoC Hub, putting the initiative in a regulatory-based testing environment.
The focus on parallel movement comes as capital markets explore how high-quality goods can move more efficiently without disrupting established controls.
A previous pilot on the Canton Network in December 2025 saw the US Treasury also used as collateral between institutions such as Bank of America and Société Générale, where transactions were settled in real time for multiple participants.
The lessons of that experiment indicate that it is possible to reuse government securities across different groups, reducing the delays associated with traditional settlement cycles. The new system operates on a similar model to Japan’s sovereign bond market, one of the largest in the world.
Similar efforts are underway in Europe. The United Kingdom has recently been selected by HSBC’s Orion platform to support the release of its Digital Gilt Instrument pilot within the Bank of England Digital Securities Sandbox, another step towards testing distributed ledger technology for large credit.
Japan’s digital asset push extends beyond crypto trading
Japan’s digital asset push has also been seen on the retail side, where platforms are starting to connect crypto to everyday payment systems.
Rakuten Wallet recently added XRP as a listed asset and payment option, allowing users to convert loyalty points into tokens and spend them on its large merchant network, bringing crypto exposure to tens of millions of existing users.
Institutional pilots like the JSCC test operate on a different layer, focusing on payments, collateral, and market pipelines than consumer payments. Together, these efforts point to the continued creation of a digital channel throughout the financial system.
The companies involved said the findings of the bond’s collateral testing will feed into ongoing discussions on how Japanese government bonds can be used in digital collateral processes. There is no timeline set for a commercial release.
