Japan’s financial regulators are moving to build a national blockchain settlement network for stocks and government bonds, with the Financial Services Agency, Ministry of Finance and Bank of Japan (BOJ) launching a joint study group this summer and eyeing a development plan by early 2027. The push comes as nearly 80% of Japanese institutional investors say they plan to add crypto within three years, and as Nikkei reports Japan risks losing that money to faster-moving US and EU tokenization efforts.
Tokyo’s Two-Day Problem, and Why the Fix Is Bigger Than a Ledger
A trade in Tokyo Stock Exchange shares still travels the way a letter did before email: written down, handed off, walked across town, and only counted as delivered two business days later. Japanese government bonds move a little faster, settling the next day, but the principle is the same, a physical-mail logic applied to digital money.
The Financial Services Agency, the Ministry of Finance, and the BOJ plan to close that gap to near-zero, using a blockchain-based settlement network that tokenizes a portion of the reserve accounts banks already hold at the BOJ, effectively a wholesale central bank digital currency used only between institutions.
The three agencies, per Nikkei’s original reporting, will convene a study group this summer and aim to have a formal development plan by early 2027, with live operations projected, cautiously, for the early 2030s.
The Pilots Already Running Underneath the Plan
The study group isn’t starting from nothing. The Mitsubishi UFJ Financial Group (MUFG) said this month it’s preparing a proof of concept for on-chain Japanese government bond (JGB) settlement on the Canton Network, a blockchain built for institutional settlement, and Japan’s three largest banking groups, MUFG, Sumitomo Mitsui Banking Corporation (SMBC) and Mizuho, are already piloting tokenized stocks and bonds together.
One level up, Japan Securities Clearing Corporation, the clearing house owned by Japan Exchange Group, has been trialing blockchain-based JGB collateral with Mizuho, Nomura and Digital Asset since April. Wider still, roughly 40 regional and online banks announced a proof of concept for tokenized-deposit interbank transfers the same day the study group news broke, with testing starting as early as this month.
What started as one bank’s experiment is now a banking-sector posture, and separately, the FSA’s own Payment Innovation Project has moved to actively support a parallel demonstration among Nomura Securities, Daiwa Securities and the megabanks, linking blockchain-recorded transfers of JGBs, corporate bonds, investment trusts and stocks to stablecoin-based payment.
“The Singleness of Money”
Bank of Japan officials, including Governor Ueda Kazuo, Executive Director Kamiyama Kazushige, and Deputy Governor Himino Ryozo, have spent the first half of 2026 laying out why central bank money has to remain the bridge underneath any tokenized system, not merely the infrastructure that clears trades faster.
“The essence of monetary singleness lies in maintaining a no-questions-asked state… it may often be overlooked, so long as the system functions well.”
— Himino Ryozo, Deputy Governor of the Bank of Japan
Himino’s speech goes furthest, walking through a scenario where two competing yen-denominated stablecoins trade at different implied values, and arguing that without central bank money underwriting the exchange, “the singleness of money,” the assumption that a yen is a yen no matter who’s holding it, quietly stops being guaranteed.
Settlement speed is the visible fix. Preserving that assumption is the actual project.
Himino’s Unresolved Scenario
The competitive framing is stated plainly enough in the coverage: a Nomura and Laser Digital survey found nearly 80% of Japanese institutional investors plan to allocate to crypto within three years, and Nikkei’s sourcing suggests Japan could lose that allocation to jurisdictions moving faster, as the EU and US race to modernize tokenization rules and Wall Street pushes toward 24/7 tokenized equities.
We can position ourselves at the forefront of the cutting-edge competition currently unfolding across global markets.
— Katayama Satsuki, Minister of Finance and Minister of State for Financial Services
What the plan does not yet specify, in any document reviewed for this story, is how a system built on multiple private stablecoins would resolve the exact scenario Himino describes if one issuer stumbles, nor what governance would apply to a coin that became dominant enough to matter systemically.
In July, Japan did pass amendments reclassifying roughly 105 cryptocurrencies as financial instruments, effective fiscal 2027, and the BOJ has separately expanded its own blockchain sandbox to keep testing interoperability. Whether that adds up to an answer to Himino’s question is, as of this writing, an open item on someone’s desk, not a settled part of the plan.
