Japan’s financial establishment is making its most ambitious move yet into digital assets. A consortium of the country’s largest banks and securities firms plans to tokenize Japanese government bonds and settle transactions using stablecoins. It will enable 24/7 instant settlement by the end of 2026.
JAPAN PUT ITS $1.6T REPO MARKET ON THE BLOCKCHAIN

The initiative focuses directly on the Japanese repo market. It represents roughly 10% of a $16 trillion global market. Blockchain news from Japan today does not come from startups. It comes from the heart of the country’s traditional financial system.
Who is behind this and how it works
The project is led by the Digital Asset Co-Creation Consortium, managed by Progmat. It is a blockchain infrastructure startup with close ties to Japan’s megabanks. A working group will start in May 2026, with a formal report on legal, tax and operational issues due in October. Individual proof-of-concept projects will run in parallel, with the entire initiative aiming for a live launch before the end of the year.
The working group reads like a who’s who of Japanese and global finance. MUFG, Mizuho Bank and Sumitomo Mitsui Banking Corporation, Japan’s three megabanks, are all participants. BlackRock Japan, Daiwa Securities, SBI Securities, State Street Trust Bank and Tokio Marine Holdings round out the consortium. That institutional weight is important. This is not an exploratory experiment. It is a coordinated industrial push towards live infrastructure.
The breakthrough of T+0 and why it matters
The centerpiece of the initiative is achieving a T+0 settlement. Finality on the same day, via transactions in the chain. The current Japanese standard is T+1, which means settlement takes place the business day after a transaction is executed. Combining tokenized JGBs with stablecoins reduces that window to almost zero.
For Bank of Japan news watchers, the capital regulation angle is significant. Because T+0 positions can be opened and closed within one day, they do not appear on end-of-day balances. This structure could potentially exempt these transactions from capital adequacy rules. It risks weights and leverage ratios that currently limit how aggressively banks can participate in repo markets.
Borrowers gain efficient intraday liquidity. Lenders, including non-residents, will receive a new investment vehicle that combines JGB-level security with 24-hour accessibility.
What this means for investors and developers
For investors, the Japanese move signals that tokenized government bonds are evolving from pilot projects to market infrastructure. DTCC has already processed more than $330 billion in tokenized Treasury transactions in the US repo market. Japan is joining this trend, opening a $1.6 trillion segment for blockchain rails. MUFG’s Progmat platform as connective tissue.
For developers building on institutional blockchain infrastructure, the DCC Working Group represents an open framework. The consortium explicitly organizes issues from a legal, accounting, fiscal, operational and technological perspective. It creates a compliance playbook that other markets will likely refer to. Japan has historically been deliberate in financial innovation. When it moves, it moves with conviction. The repo market that goes into production at the end of 2026 is not a ‘maybe’. It is a planned deployment.
