Japan is preparing to build a blockchain-based financial infrastructure that could allow stocks and Japanese government bonds to settle almost instantly, potentially reshaping how transactions are processed across one of the world’s largest financial markets.
The Financial Services Agency (FSA), Ministry of Finance, Bank of Japan (BOJ) and domestic financial institutions are expected to launch a study group this summer to examine the proposed system. According to Nikkei, the group could produce a development plan as early as the beginning of 2027, covering the blockchain’s design, responsibilities among participating institutions and regulators, and a roadmap for development and deployment.
If approved, the system could begin operations within several years and potentially become fully operational in the early 2030s. The project may also be incorporated into a multi-year strategic investment framework that Japan plans to establish from fiscal 2027.
Japan is reportedly developing plans for instant blockchain settlement of stocks & bonds
Japan Wants to Eliminate Settlement Delays
The main objective is to replace Japan’s existing settlement cycles with near-real-time transactions.
Japanese stock trades currently follow a T+2 settlement cycle, meaning cash and securities are exchanged two business days after a transaction is executed. Japanese government bonds, meanwhile, generally settle on a T+1 basis.
Under the proposed blockchain infrastructure, the transfer of securities and payment could occur as part of the same process. Buyers would receive their securities while sellers receive funds almost immediately, reducing the time during which both sides remain exposed to settlement risk.
For investors, faster settlement would also mean quicker access to proceeds. Money received from selling stocks or bonds could potentially be reinvested almost immediately instead of remaining tied up during the settlement period.
The change could also improve liquidity management for banks, brokerages and other financial institutions. At the same time, moving toward instant settlement would require participants to have sufficient cash and securities available at the time of each transaction, creating new operational and liquidity requirements that regulators will need to address.
Tokenized Bank Balances Could Power the System
One of the most significant elements of Japan’s proposal is the potential use of tokenized portions of commercial banks’ current-account balances at the BOJ.
Rather than creating a consumer cryptocurrency, the concept would digitally represent existing central bank money on a blockchain network. Participating financial institutions could then use those tokens to settle securities transactions directly through the network.
The approach is consistent with work already underway in Japan. In April, the FSA announced support for a demonstration project focused on interbank settlement using tokenized deposits. The BOJ is also conducting a sandbox project in which current-account balances held at the central bank can be converted into tokens and used in blockchain-based transactions.
The initiative is gaining broader participation. Roughly 40 regional and online banks are preparing a proof of concept for interbank transfers using tokenized deposits, with testing beginning this month. A separate announcement on August 26 said 43 companies are participating in the FSA-supported tokenized-deposit interbank settlement experiment.
These projects could provide Japan with important building blocks for connecting tokenized money with digital securities.
Blockchain Push Extends Across Japan’s Financial System
The proposed settlement network is part of a much wider push by Japanese authorities and financial institutions to bring blockchain technology into regulated markets.
In April, Japan Securities Clearing Corporation began a trial with Mizuho, Nomura and Digital Asset to explore the use of tokenized Japanese government bonds as blockchain-based collateral. Mizuho Bank, MUFG and SMBC are also working on a stablecoin pilot with regulatory backing.
The BOJ has simultaneously been exploring wholesale digital-money infrastructure. In June, the central bank said its work was aimed at developing efficient and stable settlement systems, including delivery-versus-payment settlement for digital assets using central bank money. It also highlighted Project Agorá, an international initiative involving seven central banks and more than 40 private financial institutions to examine tokenized bank deposits and central bank money for cross-border payments.
Japan’s regulatory framework is evolving alongside these experiments. The country has been preparing amendments that would bring certain crypto assets into a financial-instrument framework from fiscal 2027. Japan’s tax reform framework also provides for a separate 20% tax rate on qualifying crypto-asset gains once the relevant rules take effect.
A Longer-Term Goal for Cross-Border Payments
The proposed blockchain infrastructure could eventually have applications beyond Japanese stocks and government bonds.
Nikkei reported that the system could potentially be extended to international remittances. That would align with Japan’s broader participation in efforts to modernize cross-border payments through tokenized deposits and central bank money.
For now, however, the project remains at the planning and study stage. Japan has not selected a blockchain network, finalized the operating model or committed to a launch date. The development plan expected in early 2027 will be an important milestone in determining whether the proposal can move from experimentation to national infrastructure.
Still, the direction of travel is becoming clear. Japan is no longer treating blockchain solely as a technology for cryptocurrencies. It is increasingly exploring the technology as part of the underlying infrastructure for regulated money, securities and payments.
If the project eventually reaches full deployment in the early 2030s, Japan could move from T+2 and T+1 settlement toward a system where securities and payment change hands almost simultaneously—potentially setting a new benchmark for the country’s financial-market infrastructure.
