Japan's LDP Backs Stablecoins as Financial Infrastructure

Japan's Liberal Democratic Party formally approved the "Next-Generation AI and On-Chain Finance" policy proposal on May 19, 2026, designating yen-denominated stablecoins and tokenized deposits as core national financial infrastructure — a step that places blockchain settlement on the same policy footing as conventional payment rails. The proposal was drafted by an LDP project team led by lawmaker Seiji Kihara and cleared by the party's Policy Research Council and Digital Society Promotion Headquarters, according to The Block's reporting via Decrypt.

At the center of the initiative is a coordinated effort by three of Japan's largest banks. Mitsubishi UFJ Financial Group, Sumitomo Mitsui Banking Corporation, and Mizuho Financial Group are jointly studying stablecoin issuance and tokenized deposit infrastructure under the Payment Innovation Project, with practical corporate use cases targeted for completion by March 2027, as CoinEdition reported citing The Block. The three institutions have been exploring this collaboration since at least late 2025, when their joint stablecoin plans were first reported publicly.

The LDP proposal requests the Financial Services Agency to develop a five-year roadmap for integrating blockchain settlement into Japan's financial system. Key regulatory elements include the tokenization of Bank of Japan current account deposits, clarification of stablecoin legal status for wage payments and tax transactions, and the establishment of an "AI/On-Chain Finance Asia Policy Dialogue Framework" to coordinate regional standards on RWA interoperability and KYC/AML compliance. The proposal also designates finance as Japan's eighteenth growth investment sector, a classification that carries implications for public funding prioritization and regulatory fast-tracking, according to Coinfomania.

The regulatory groundwork for foreign stablecoin participation was also advancing in parallel. Japan's FSA moved to create a legal path for foreign-issued stablecoins under amended rules, with implementation scheduled from June 2026, as CryptoTimes reported on May 19, 2026. That step addressed a longstanding gap in Japan's Payment Services Act framework, which had previously restricted foreign stablecoin issuers from operating in the domestic market without a local entity. The amended rules and their compliance requirements are detailed in analysis published by Global Law Experts.

The strategic rationale behind the LDP proposal is explicitly defensive as well as developmental. The document frames the initiative as a response to the dominance of USD-pegged stablecoins in global digital finance, citing the risk to yen sovereignty if Japan's financial institutions remain outside the on-chain settlement infrastructure being built elsewhere. The proposal calls for AI-driven transaction automation to be integrated alongside blockchain rails, reflecting the project team's view that the two technologies are operationally linked in next-generation payment architecture, according to crypto.news.

The three-bank consortium's stablecoin work builds on earlier proof-of-concept activity. MUFG, SMBC, and Mizuho received regulatory clearance for a stablecoin issuance trial, with the Progmat platform serving as infrastructure for MUFG's tokenization efforts, as CoinTelegraph reported. The Payment Innovation Project represents a formalization of that earlier exploratory work into a structured, multi-institution program with a defined commercial timeline.

Several material details remain undisclosed in the LDP proposal and associated bank announcements. The proposal does not specify the technical architecture for tokenizing Bank of Japan current account deposits, the governance structure of the proposed Asia Policy Dialogue Framework, or the criteria by which the FSA will evaluate progress against the five-year roadmap. The three banks have not disclosed the specific corporate use cases targeted under the March 2027 timeline, the fee structures for tokenized deposit services, or the interoperability standards that would govern cross-border RWA transactions under the proposed regional framework.

The immediate effect of the May 19 approval is that stablecoins and tokenized deposits now carry explicit LDP policy backing as national infrastructure — a designation that formally directs the FSA to produce a structured regulatory roadmap. What the proposal does not establish is a live tokenized deposit product, a completed stablecoin issuance by any of the three banks, a finalized legal definition of stablecoin status for wage and tax payments, or a functioning regional coordination body for RWA standards in Asia.
