Japan’s clearing arm JSCC has begun testing whether government bonds can function as digital collateral on blockchain infrastructure.
Summary
- JSCC has launched a proof of concept with Mizuho, Nomura, and Digital Asset to test Japanese government bonds as on-chain collateral.
- The trial 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 collateral use as institutions explore 24-hour blockchain-based settlement systems.
According to a Monday announcement from Japan Securities Clearing Corporation, part of Japan Exchange Group, the firm 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 Book-Entry Transfer Act and the Financial Instruments and Exchange Act.
Maintaining legal recognition sits at the core of the exercise, as any shift to digital infrastructure must align with existing frameworks that govern how bonds are issued, held, and transferred.
Participants will also test whether current market systems can integrate with Canton’s blockchain stack to support real-time collateral movement on a 24/7 basis, including across borders.
Japan’s Financial Services Agency selected the project earlier this year under its Payment Innovation Project, part of the FinTech PoC Hub, placing the initiative within a regulatory-backed testing environment.
Focus on collateral mobility comes as major markets test how high-quality assets can circulate more efficiently without disrupting established oversight.
An earlier pilot on the Canton Network in December 2025 saw tokenized U.S. Treasuries reused as collateral between institutions such as Bank of America and Société Générale, where transactions were settled in real time across multiple participants.
Lessons from that trial pointed to the possibility of reusing government securities across different counterparties on-chain, reducing delays tied to traditional settlement cycles. The new initiative applies a similar model to Japan’s sovereign bond market, one of the largest in the world.
Parallel efforts are also underway in Europe. The United Kingdom recently selected HSBC’s Orion platform to support issuance for its Digital Gilt Instrument pilot within the Bank of England’s Digital Securities Sandbox, another step toward testing distributed ledger technology for sovereign debt.
Japan’s digital asset push expands beyond crypto trading
Japan’s digital asset push has also been visible on the retail side, where platforms are starting to plug crypto into everyday payment systems.
Rakuten Wallet recently added XRP as both a listed asset and a payment option, allowing users to convert loyalty points into the token and spend it across its large merchant network, bringing crypto exposure to tens of millions of existing users.
Institutional pilots such as the JSCC trial operate on a different layer, focusing on settlement, collateral, and market plumbing rather than consumer payments. Together, these efforts point to a steady build-out of digital rails across the financial system.
The companies involved said findings from the bond collateral test will feed into ongoing discussions on how Japanese Government Bonds could be used in digital collateral processes. No timeline has been set for a commercial rollout.
