Japan JSCC Mizuho, & Nomura Launch Blockchain JGB Collateral

• The initiative is a PoC trial aimed at determining if JGBs can work as digital collateral.
• The pilot will center on moving and managing JGBs on the Canton Network.
• It will also test if all the digital work fits inside Japan’s current legal system.

Japan Securities Clearing Corporation (JSCC) has partnered with Mizuho Financial Group and Nomura Holdings to test the use of blockchain technology for managing Japanese government bonds (JGBs).

JSCC Partnered To Use Blockchain For Government Bonds

Announced on April 20, the initiative is a proof of concept (PoC) trial aimed at determining if JGBs can work as digital collateral on the blockchain, a big step toward tokenizing traditional finance.

The pilot will center on moving and managing JGBs on Canton Network, a blockchain platform built specifically for institutional finance. Main goals include testing moving and holding JGBs on‑chain, enabling real‑time collateral moves, and exploring cross‑border settlement.

This pilot is part of a project that Japan’s FSA (Financial Services Agency) picked in February 2026 to support under its Payment Innovation Program (PIP).

The trial will also test if all this digital work fits inside Japan’s current legal system, so that tokenized bonds still count as valid under financial laws.

In the announcement, it was also stated that the test will include cross‑border deals with stakeholders inside and outside Japan. It will check how collateral moves between clearinghouses, big investors, clients, and agents.

Notably, Japan’s government bond market is one of the largest in the world, with outstanding issuance exceeding ¥1,000 trillion (roughly $6.28 trillion). If successful, the pilot could make JGBs more usable worldwide, boost global liquidity, and become a model for other countries’ bond systems.

Japan’s New Regulatory Crypto Framework

As for Japan itself, the country is tightening its regulatory framework and plans to officially classify crypto as a financial product under new legislation. It would ban insider trading and force issuers to disclose more. Penalties of up to 10 years in prison would also be imposed.

This would align crypto more with traditional securities rules, which would be a huge legal shift for Japan’s digital asset policy.

Interestingly, other countries in Asia are having similar efforts. For instance, in South Korea, Ripple has teamed up with Kyobo Life Insurance to make tokenized government bond deals possible. Additionally, South Korea’s finance ministry has started pilot testing blockchain‑based deposit tokens for paying official government fees.
