- JPX launches blockchain PoC to test JGBs as digital collateral under legal frameworks.
- Trial targets 24/7 collateral transfers with compliance and cross-border capabilities.
- Japan backs tokenization push with stricter crypto rules and investor safeguards.
Japan Exchange Group (JPX) announced a proof-of-concept initiative with major financial firms to test Japanese government bonds as digital collateral using blockchain. The program will examine transfer, management, and legal compliance under existing financial laws.
The initiative brings together Mizuho Financial Group, Nomura Holdings, Japan Securities Clearing Corporation, and Digital Asset Holdings. It will operate on the Canton Network to test on-chain handling of Japanese government bonds.
According to the official release, the program will assess whether JGBs can move across blockchain systems while retaining legal status. The design follows Japan’s Book Entry Transfer Act and the Financial Instruments and Exchange Act.
JPX Trial Targets 24/7 Collateral and Blockchain Integration
The trial will also review how current financial processes connect with blockchain infrastructure. It aims to support continuous collateral transactions beyond standard operating hours. The joint announcement stated that the trial will test efficient collateral management within existing rules. It will focus on maintaining compliance while enabling on-chain transfers.
Participants will examine real-time processing across a 24/7 framework. The study will also explore cross-border use involving clearing houses, institutional investors, and clients. Japan’s Financial Services Agency selected the project in February. It falls under the Payment Innovation Project within the FinTech PoC Hub.
The selection follows earlier initiatives linked to stablecoins and cross-border payments. It reflects ongoing efforts to expand financial technology testing in controlled environments. The PoC will be jointly led by participating institutions. Each group contributes expertise in clearing, settlement, and bond market operations.
JPX and JSCC provide infrastructure for clearing and settlement functions. Banking participants support the structure through their roles in the JGB market. Japan has also introduced new regulatory proposals tied to digital assets. On April 10, 2026, the government proposed changes to financial laws.

The proposal classifies crypto assets as financial instruments. Oversight would shift to the Financial Instruments and Exchange Act. The framework includes restrictions on insider trading using nonpublic information. It also requires disclosure of financial activity by crypto-asset issuers.
Japan Tightens Crypto Rules as Tokenization Grows
Crypto exchanges would become crypto asset trading operators. The fines would be heightened to enhance enforcement. The length of terms in prison would be increased to ten years. The fines would be raised to ¥10 million instead of ¥3 million.
The proposal will enhance protection of investors and market structure. It also corresponds rules to the increasing position of digital assets. With a diet approval, the changes could become effective by the fiscal year 2027. The schedule represents the normal legislative processes.
The JPX project is timed as institutions start to take an increasing interest in tokenization. Companies are considering blockchain as a way of collateral functions and settlement. Issues of alignment of regulations and system interoperability still exist. The reliability of operation is also one of the adoption factors.
The trial offers a controlled environment to test blockchain applications. Regulatory assistance can be used to evaluate without influencing market stability. The result can be the acceleration of collateral flow and reduction of operation expenses. It could also enable continuous market activity across global participants.
