Japan blockchain finance plan backs tokenized deposits

Japan’s ruling Liberal Democratic Party approved a proposal Tuesday that would build a next-generation financial system on blockchain and artificial intelligence, shifting the country’s digital-asset debate away from crypto trading and toward the plumbing of money, settlement and supervision.

A five-year roadmap sits at the centre of the package, which The Block first reported and which explicitly backs tokenized deposits alongside yen stablecoins. BloomingBit’s account framed the same proposal as an attempt to move stablecoins and tokenized deposits from pilot status into national policy. Banks, infrastructure operators and regulators have already been testing pieces of this stack. The LDP has bundled those pieces into a political signal that digital rails belong inside mainstream finance, not at its edges.

Reading the proposal as an insider produces a less dramatic picture than the headline. Banks do not need another crypto narrative; they need a way to make interbank money move around the clock without ripping out core systems or breaking the legal treatment of deposits. Market-plumbing details carry more weight than the AI branding. The DeCurret DCP project supported by the FSA’s FinTech PoC Hub is aimed at 24/7 settlement using tokenized deposits — a far more concrete milestone than the party’s rhetoric.

Kihara described the proposal as an opening brief rather than finished law.

“It is truly a ‘concept,’ and from here on, we will build it up piece by piece.”

Kihara was speaking as the LDP project team lead, and his framing matters. The proposal leaves open the live institutional question at the centre of Japan’s digital-money debate: whether the country is converging on tokenized deposits, bank-issued stablecoins or a layered model that uses both. A Forrester analysis of Japan’s stablecoin market argued that stablecoins in Japan are being treated less as speculative instruments and more as financial infrastructure. For a market where the distinction between a deposit claim and a transferable token is a regulatory choice rather than a branding exercise, the tone shift matters. Until recently, Japanese policymakers viewed digital money largely through a retail-trading lens.

Why the cash leg matters

Strip away the technology labels and the LDP package is an argument about the cash leg of tokenized markets. Tokenized bonds, funds or equities are only useful at scale if the money used to settle them can move with the same speed and programmability as the asset itself. Japan’s lawmakers appear to have accepted this premise. They are not just talking about issuing digital assets — they are talking about what sits on the other side of the trade.

Tokenized deposits hold an advantage for institutional use: they preserve the banking relationship, keep money inside the regulated deposit system and can be designed to interoperate with existing compliance controls. Stablecoins, by contrast, may be better suited to specific payment and programmability use cases, especially where transferability across platforms is the priority. Japan looks increasingly likely to use both instruments, but for different jobs. The question is not which technology wins — it is which liability form fits which market function.

Bank of Japan Governor Kazuo Ueda said in a BIS-published speech that blockchain and AI could help shape a new financial ecosystem, adding that the technology could improve cross-border flows. In central-bank language, that means the payments rail is part of the policy story, not an add-on.

“It may bring innovation in terms of streamlining cross-border payments.”

— Kazuo Ueda, BIS

Japan’s pilots also answer the insider question about execution. The DeCurret DCP initiative is explicitly focused on interbank settlement of tokenized deposits, and the broader buildout involves three megabanks, according to The Block’s reporting. Nationwide rollout is not imminent. But the pilots do show who controls issuance, ledgering and settlement in the current Japanese model: incumbent financial institutions, with regulators close to the design process.

The scale ambition is larger than the usual pilot-language implies. Forrester’s Makoto Shibata wrote that megabank-linked stablecoin programmes are targeting roughly ¥1 trillion by 2028 — a number that signals a real economic use case, not a sandbox exercise. It also explains why Japan’s debate departs from a standard crypto-adoption script.

“Stablecoins are not speculative assets in Japan — they’re becoming financial infrastructure.”

The AI label is really a coordination signal

The skeptic case is worth taking seriously. Much of the tokenization work cited around this proposal predates the LDP vote. Japan has spent years building stablecoin rules, security-token frameworks and bank-led settlement pilots, which means the AI language does political work more than technical work — it gives lawmakers a future-facing wrapper for projects that were already moving through specialist channels.

None of that makes the proposal empty. In market structure, coordination is often the real barrier. A party-level push that asks the FSA for a five-year roadmap gives bureaucrats, banks and infrastructure operators a timetable and a mandate to converge. Nikkei’s coverage suggested the initiative is meant to support an Asia-focused public-private platform, which widens the story beyond domestic crypto policy and into regional financial competition.

Other jurisdictions are moving in parallel. In the US, The Block reported that the SEC is weighing an innovation exemption for tokenized securities. The policy race is therefore not about who allows tokenized assets first. It is about who builds a coherent system in which tokenized assets, tokenized cash and compliance logic can operate together without constant legal improvisation.

Interpreting the AI component becomes easier in that light. Nothing in the public proposal suggests Japan is trying to turn finance into an autonomous trading machine. The narrower reading is more useful: AI as tooling for compliance, risk review, workflow routing and data handling inside a tokenized settlement environment. If blockchain defines the ledger logic, AI is being positioned as the operating layer that helps institutions manage scale and complexity.

Japan’s LDP is making a market-structure bet, not placing a symbolic wager on crypto. It is treating blockchain and AI as candidate layers in national financial infrastructure — the same way earlier generations treated payment networks, message standards and exchange connectivity. The harder part comes next. Lawmakers have blessed the direction. The FSA and the banks still have to decide what form of digital money can actually carry it.
