The LDP's Digital Society Promotion Headquarters, a body within the party's Policy Research Council, approved the document in May 2026.

Titled the "Next-Generation AI and On-Chain Finance Vision," the proposal names tokenized deposits and stablecoins as the twin foundations of a rebuilt payment system and proposes that the Financial Services Agency lead a five-year national roadmap for tokenizing real-world assets including accounts receivable and real estate.

The most concrete deliverable in the proposal is a joint yen-backed stablecoin to be issued by MUFG, Mizuho, and SMBC, Japan's three megabanks, with a target operational date of March 2027.

The three institutions are already collaborating on Project Pax, a stablecoin initiative built on the Progmat Coin platform that received FSA pilot approval in November 2025 and is targeting one trillion yen in business-to-business issuance by 2028. Japan's yen stablecoin ecosystem also includes JPYC, the country's first regulated yen stablecoin, which received its license in October 2025, and DCJPY, which has reached operational status. The LDP's formal endorsement of the megabank initiative elevates yen-denominated digital currency to an explicit national policy priority.

The proposal frames urgency in terms of monetary sovereignty rather than innovation. Japan's domestic stablecoin market is estimated at roughly 45 trillion yen (approximately $312 billion), but the overwhelming majority of that volume is denominated in dollar-backed USDT and USDC, though available data do not separately quantify the precise domestic share of USD-backed stablecoins.

Former Digital Minister Takuya Hirai has publicly warned, according to secondary reporting, that this concentration represents a significant dependence on foreign financial infrastructure and payment rails.

The LDP document echoes that concern, stating that a slow response "could deepen reliance on overseas payment systems and weaken monetary sovereignty."

Finance has been formally designated Japan's 18th growth investment sector under the proposal, signaling direct government fiscal support and public-private co-investment.

The policy also covers terrain that goes beyond payments. The LDP explicitly names "agentic commerce" as the infrastructure's target environment: an economy where AI agents autonomously execute payments, lending, and asset management around the clock without direct human instruction.

The document describes on-chain financial infrastructure as "urgently needed to prepare for the era of agentic commerce, in which AI agents autonomously conduct economic activity."

On the security side, the proposal acknowledges quantum computing as a long-term threat to blockchain cryptography and urges the Digital Agency to establish a permanent monitoring system for that risk.

The proposal lands within a broader regulatory reset that has moved quickly in 2026. Sanae Takaichi led the LDP to a general election victory in February 2026 on a platform that included explicit pro-crypto commitments, entering office as Prime Minister following the party's win.

In April, Japan's cabinet reclassified Bitcoin, Ethereum, and other cryptocurrencies as financial products under the Financial Instruments and Exchange Act, a significant shift from their previous status as payment instruments.

The country's capital gains tax on qualifying crypto assets is also set to drop from a top rate of 55 percent to a flat 20 percent, with a three-year loss carryover provision, pending formal legislative passage.

Japan's crypto user base currently stands at approximately 12 million.

Regional Implications

The proposal includes a named cross-border initiative, the Global Stablecoin Corridor Initiative, aimed at expanding yen-based payment rails internationally, alongside the AI and On-Chain Finance Asia Policy Dialogue Framework.

South Asian economies including Bangladesh, Nepal, India, and Sri Lanka, as well as Southeast Asian economies such as the Philippines, all maintain major remittance corridors with Japan, and South Asian stablecoin volumes already jumped 80 percent to $300 billion in the first seven months of 2025.

SBI Holdings, one of the institutions behind the JPYSC yen stablecoin launching in Q2 2026, has operated blockchain payment corridors through SBI Ripple Asia, with established corridors serving South Korea, India, and the Philippines.

A regulated yen stablecoin corridor would give South Asian and Southeast Asian economies a non-dollar settlement option, relevant for countries managing dollar-peg pressure or capital controls.

For Africa, the indirect effects are worth watching. Sub-Saharan Africa accounts for 43 percent of all crypto transactions in the region, with over $200 billion moved on-chain in the year ending June 2025. Average remittance fees on a $200 transfer in the region sit at 7.9 percent. Research from Transak indicates that stablecoin remittance corridors can reduce transfer costs by up to 85 percent, and any new regulated stablecoin corridor adds meaningful competitive pressure to those costs.

Japan's Official Development Assistance history across East Africa also gives the AI and On-Chain Finance Asia Policy Dialogue Framework a plausible path toward broader engagement.

The FSA's five-year RWA roadmap and the March 2027 megabank stablecoin deadline are the two most time-sensitive benchmarks to track.

Developers building tokenization infrastructure or post-quantum cryptography tools have a defined regulatory window to engage Japan's sandbox programs now.

Verse Press analysts note that the Progmat Coin platform and Startale's Astar Network are the most likely technical substrates for the infrastructure the LDP is describing, though neither has been formally designated by the LDP or the FSA.
