Key Highlights
- JPX is developing a PoC project using blockchain technology for collateral management, employing JGBs as the collateral.
- The project includes the participation of organizations such as Mizuho, Nomura, JSCC, and Digital Asset through the Canton Network.
- It will be investigated whether there can be a seamless transfer of the collateral without violating any financial regulations.
The Japan Exchange Group (JPX) has announced a PoC initiative in collaboration with Mizuho Financial Group, Nomura Holdings, Japan Securities Clearing Corporation (JSCC), and Digital Asset Holdings to use Japanese Government Bonds (JGBs) for digital collateral purposes via Canton Network.
As stated in JPX’s official announcement released Monday, the program is designed to examine the feasibility of transferring and managing JGBs using blockchain technology, while ensuring that they retain their legality through Japan’s Book Entry Transfer Act as well as the Financial Instruments and Exchange Act.
The project will also analyze how existing financial processes can be integrated into Canton’s blockchain network, facilitating round-the-clock transactions of collateral.
Trial focuses on compliance and real-time transfers
According to the joint announcement, the trial will assess whether blockchain can support efficient collateral management without disrupting existing legal and supervisory frameworks. Key objectives include verifying the seamless on-chain movement of JGB collateral while maintaining compliance and exploring 24/7 real-time processing that could extend to cross-border use cases involving clearing houses, institutional investors, and clients.
Japan’s Financial Services Agency (FSA) selected the initiative in February for support under its Payment Innovation Project (PIP), part of the FinTech PoC Hub. This reflects Japan’s continued focus on fintech innovation, building on earlier PIP-supported projects involving stablecoins and cross-border payments.
The PoC will be jointly led by Mizuho Financial Group (President & Group CEO: Masahiro Kihara), Nomura Holdings (Representative Executive Officer and President and Group CEO: Kentaro Okuda), JSCC (President & CEO: Isao Hasegawa), and Digital Asset (CEO: Yuval Rooz). The joint effort leverages the strengths of JPX/JSCC in the domain of clearing and settlement services and the participation of the banks in JGB markets.
Proactive stance on digital market
Japan has so far been active in digital markets and, so, in regulations. Japan’s government introduced an amendment to the country’s law regulating finance on April 10, 2026.
Under the proposal, crypto assets would be classified as financial instruments, shifting oversight from the Funds Settlement Act to the stricter Financial Instruments and Exchange Act, reflecting their growing role as investment assets. Some key clauses stipulate the prohibition of insider trading based on nonpublic information and require crypto-asset issuers to disclose the details of their financial activity.
Crypto-exchange operators will now be called “crypto asset trading operators.” Violations will be penalized much more harshly to secure the protection of investors; thus, jail terms increase from three to 10 years, and fines from ¥3 million to ¥10 million.
These regulations will promote equity in the marketplace and help provide sufficient capital and investor protection at the same time. Once approved by the Diet, they may become effective as early as fiscal year 2027.
Growing institutional interest in tokenization
The PoC comes at a time when there is a greater interest in asset tokenization from institutions. Although hurdles do exist, such as regulatory harmony, interoperability, and robust operations, the trial in Japan indicates a prudent but futuristic regulatory approach.
By supporting the project through the FinTech PoC Hub, the FSA has provided a platform for testing the innovation while protecting the integrity of the market. The success of the project may result in increased movement of collateral, reduced operational costs, and dynamic markets that run throughout the day.
