#JapanMOFStudyGroupOnTokenizedGovtBonds: Japan Plans 24/7 Blockchain Settlement for its $7 Trillion Bond Market
Japan is moving to put its government bonds on-chain.
The Ministry of Finance (MOF), Financial Services Agency (FSA), Bank of Japan (BOJ) and major private banks are launching a joint Study Group on Tokenized Government Bonds & Blockchain Settlement this summer 2026, with a development plan targeted for early 2027 and a potential live system in the early 2030s.
This is not a small pilot. It is a fundamental rebuild of how Japan settles its securities.
What The Group Will Do
According to Nikkei, the study group has three tasks:
1. Design the rails: Choose whether to build a new permissioned chain, link several regulated networks, or bolt distributed ledger tech onto existing market infrastructure.
2. Divide responsibility: Decide who operates what between MOF (issuer of JGBs), FSA (regulator), BOJ (cash leg), Japan Securities Clearing Corp (JSCC), and banks/brokers.
3. Roadmap: Set the timeline for trials and formal approval, potentially under the government's multi-year strategic-sector investment framework from fiscal 2027.
How It Would Work
At the core of the plan is tokenized BOJ reserves.
Today commercial banks hold reserve accounts at the BOJ. Under the proposal, a portion of those reserves would be converted into digital tokens circulating on the new blockchain. Securities and cash would then change hands simultaneously on-chain - atomic settlement, delivery vs payment in real time.
This is a wholesale CBDC model, not for retail consumers, but for interbank settlement.
Why Now?
Settlement in Japan is still slow:
- JGBs: T+1 (one business day after trade)
- Stocks: T+2 (two business days)
That delay ties up cash and collateral. Japan already narrowed it - JGBs moved to T+1 in 2018, stocks to T+2 in 2019. The US moved stocks to T+1 in 2024. Japan wants to leapfrog all of them to T+0, near-instant, 24/7.
The scale is massive. MOF data shows Japan has about ¥1,166 trillion (∼$7 trillion) in outstanding JGBs and bills, and Tokyo and Nagoya exchanges processed ¥3.39 quadrillion in trading volume last fiscal year.
With interest rates rising again in Japan after decades of zero, the cost of that 1-2 day float is becoming expensive.
Private Sector Is Already Moving
The MOF group is not starting from zero:
- In May 2026, Progmat - the blockchain infrastructure arm backed by Mitsubishi UFJ, Mizuho and SMBC - formed a Tokenized Government Bonds & On-Chain Repo Working Group inside its Digital Asset Co-Creation Consortium. It aims to publish a report in Oct 2026 and launch tokenized JGBs and on-chain repo using stablecoins for T+0 settlement.
- Since April 2026, Mizuho, Nomura, JSCC and Digital Asset have been testing tokenized JGB collateral transfers on the Canton Network for 24/7 trading.
- In July, SBI Global Asset Management and DigiFT launched a tokenized Japanese equity fund on Solana, and SBI Holdings partnered with Solana Foundation on yen stablecoins.
A Nomura-Laser Digital survey in April 2026 found 79% of Japanese institutional investors expect to invest in crypto within 3 years.
What Changes If It Succeeds?
1. Capital efficiency: Sellers can reinvest proceeds instantly instead of waiting a day.
2. Repo market boost: Japan's repo market is ∼10% of the global $16 trillion market. Tokenized JGBs as collateral could enable intraday funding.
3. Competitiveness: FSA says Japan risks losing flow to US and EU if it does not offer tokenized settlement.
The biggest questions left for the study group: how to handle reversals on a finality ledger, how to supervise a market that never sleeps, and how to ensure privacy and cyber resilience for the world's second-largest government bond market.
