Stocks, real estate, and bank deposits all moving on the same digital ledger, with AI handling the trading. Japan's ruling party has started rebuilding financial policy on that assumption. With the country's three largest banks already preparing a shared stablecoin and a new political task force pushing for a national strategy, Japan is making a real bet on on-chain finance.

The Ruling Party Creates an On-Chain Finance Task Force

On March 24, 2026, Japan's Liberal Democratic Party (LDP) officially launched the "Next-Generation AI & On-Chain Finance Vision Project Team" (PT) under its Digital Society Promotion Headquarters, holding its first meeting the same day.

So what exactly is "on-chain finance"? In simple terms, it's about digitizing all kinds of assets, stocks, bonds, real estate, even bank deposits, and putting them on a blockchain (a tamper-resistant digital ledger shared across many computers). When you add AI into the mix, you get a system where trades and payments can happen automatically without human middlemen.

The PT was initiated by Masaaki Taira, a member of the House of Representatives and former Digital Minister who has been driving Japan's AI and Web3 policies; he serves as deputy chair. The chair is Seiji Kihara, a former Deputy Chief Cabinet Secretary and Ministry of Finance official. Hideki Murai, another Diet member, serves as secretary-general.

This is not just a study group. The team plans to compile a white paper with policy recommendations and push to have them included in the government's annual "Basic Policy on Economic and Fiscal Management" (known as Honebuto no Houshin), the document that shapes Japan's national economic strategy each year.

In an exclusive interview before the launch, Taira emphasized that this transformation is "not five or ten years away, it will happen within a few years." The turning point, he said, was last year's World Economic Forum in Davos, where there was widespread agreement that the combination of AI and blockchain would create the greatest value in the financial sector.

Why Politicians Are Leading This, Not Bureaucrats

Taira repeatedly highlighted a critical gap: the lack of a shared "big picture." Within Japan, the individual building blocks are already falling into place. In October 2025, Japan saw the launch of JPYC, the country's first yen-backed stablecoin (a digital currency designed to maintain a stable value pegged to the Japanese yen, worth approximately $0.0067 at current rates). Japan's three mega-banks, MUFG, SMBC, and Mizuho, are preparing to jointly issue their own stablecoin. Japan Post Bank is exploring "tokenized deposits" that would allow customers to use their savings on blockchain platforms. Nomura Holdings and Daiwa Securities have begun testing blockchain-based settlement for stocks and bonds.

Yet Taira pointed out that while "the individual pieces are coming together, there is no shared vision of how to connect them into a functioning financial system." The challenges cut across multiple regulatory domains, trust law, deposit insurance, KYC (Know Your Customer) requirements, and Japan's siloed ministry structure makes cross-cutting coordination difficult.

"When you leave something this big to individual ministries, responsibilities stay vague and nothing moves forward," Taira said. This sense of urgency drove the creation of the PT. With Kihara, a former Ministry of Finance official, as chair, the message to regulators at the Financial Services Agency (FSA) and Ministry of Finance is clear. Taira described it as creating "a sense of tension, they can't run away from this."

The "Double Investment" Dilemma for Mega-Banks

Building on-chain finance requires not just startups but the participation of established banks and securities firms. But these institutions face a unique dilemma that Taira calls "double investment" (nijuu toushi).

Banks must maintain their existing massive infrastructure, the Zengin System (Japan's domestic interbank network) and SWIFT (the global payment messaging network), while simultaneously investing in new blockchain-based systems. Add in the challenges of retraining staff and the risk of deposit outflows to digital platforms, and the picture becomes clear: "They know they should do it, but the question of whether to do it now causes paralysis."

This is precisely where political leadership becomes essential. If the ruling party's recommendations become part of national economic strategy, it provides institutional cover for banks to justify their investments to shareholders and regulators alike.

Japan's Unique Strategy: Regulation First, Innovation Within

What sets Japan apart in the global on-chain finance race is its "regulation-first" approach. Through amendments to the Fund Settlement Act in 2023, Japan established one of the world's earliest legal frameworks for stablecoins, classifying them as "electronic payment instruments." This laid the groundwork for JPYC's launch and the mega-banks' joint stablecoin initiative.

On March 18, 2026, SBI VC Trade, Daiwa Securities Group, and bitbank published results from an AMM (Automated Market Maker) pilot conducted under the FSA's "FinTech Proof-of-Concept Hub." An AMM is a core DeFi (Decentralized Finance) technology that uses pre-funded liquidity pools and algorithms to automatically match trades, instead of relying on traditional order books. Testing this within Japan's regulatory framework is a globally unique experiment.

Japan's 2026 tax reform outline also included a landmark change: cryptocurrency gains will shift from the current maximum rate of 55% to a flat 20% under a separate taxation system, aligned with stocks and other financial instruments. This reform, expected to take effect around 2028 alongside amendments to the Financial Instruments and Exchange Act, could dramatically change Japan's attractiveness for digital asset investors.

How Japan Compares

United States: Rapid Regulatory Clarification

The wider policy wave of treating AI and on-chain finance as one problem traces to US Executive Order 14178, "Strengthening American Leadership in Digital Financial Technology," signed in January 2025. The US then signed the GENIUS Act into law in July 2025, creating the first federal framework for stablecoins. It requires issuers to hold 100% reserves in liquid assets and provide monthly public disclosures. Then on March 17, 2026, the SEC and CFTC jointly issued a landmark interpretation classifying crypto assets into five categories: digital commodities, digital collectibles, digital tools, stablecoins, and digital securities. SEC Chairman Paul Atkins declared the end of "more than a decade of uncertainty."

Europe: MiCA in Full Force

The EU's Markets in Crypto-Assets Regulation (MiCA) became fully operational by the end of 2024, establishing harmonized rules across all 27 member states. Stablecoin issuers must maintain 1:1 reserve backing, undergo regular audits, and comply with anti-money laundering requirements. A "passporting" system allows companies licensed in one EU country to operate across the entire bloc.

Asian Rivals: Hong Kong and Singapore

Hong Kong has moved its "Project Ensemble" from sandbox to live pilot, testing tokenized deposits for money market fund transactions throughout 2026. Participants include HSBC, Standard Chartered, BlackRock, and Franklin Templeton, with settlements running through the HKD Real-Time Gross Settlement system.

Singapore's Monetary Authority (MAS) continues its "Project Guardian," exploring asset tokenization and DeFi applications. DBS Bank and J.P. Morgan's Kinexys are building a framework for cross-chain tokenized deposit transfers.

Japan's distinctive approach combines early regulatory clarity with deep engagement from traditional financial institutions. While the U.S. favors startup-driven innovation and Hong Kong and Singapore focus on attracting global capital, Japan aims to transform its existing financial system from within, embedding blockchain into the infrastructure that everyday people already use.

What Does This Mean for Ordinary People?

On-chain finance isn't just a story for Wall Street or Kabutocho (Tokyo's financial district). Taira, drawing on his own experience as a small business owner, pointed out that instant settlements could eliminate the cash flow gaps that plague small companies. Currently, Japanese businesses often operate on month-end billing with payment delays of 30-60 days. Smart contracts, self-executing programs on the blockchain, could make payment automatic upon delivery.

International money transfers could also be transformed. Traditional cross-border payments take 3-5 business days and cost 2-7% in fees. Stablecoin transfers could settle in minutes at a fraction of the cost.

If securities trading becomes more efficient and intermediary costs drop, those savings could eventually flow back to consumers through lower fees and better interest rates.

What Happened Next: A Recommendation in Two Months

The PT moved quickly. Roughly two months after its first meeting on March 24, on May 19, 2026, it produced a 13-page set of recommendations, approved by the LDP's Policy Deliberation Commission. This is the attempt to write down the "whole picture" Taira had said was missing.

The recommendations include:

  • Positioning finance as a new growth investment sector
  • Expanding the use of tokenised deposits and stablecoins
  • Raising the sophistication of corporate finance and asset management through tokenisation of receivables, real estate, and securities
  • Creating on-chain use cases run by public bodies
  • Expanding payment modernisation projects into real transactions
  • Establishing a policy dialogue framework with Asian countries to strengthen international cooperation
  • Building rules for AI use in finance
  • Securing the safety of on-chain finance against quantum computing risk

Two items stand out. One is the public-private platform with Asia: rather than treating Hong Kong and Singapore purely as rivals, as this article framed them, the recommendation proposes a policy dialogue framework with them. The other is quantum computing, an attempt to price in the risk that today's blockchain cryptography breaks, at the design stage rather than after.

Taira has said elsewhere that when he creates a PT, it nearly becomes national policy. Whether the recommendations land in the government's Basic Policy is the next thing to watch.

Where Is Japan Heading?

The LDP's new project team represents a declaration of intent: Japan wants to be among the global leaders in on-chain finance. The individual technologies and regulatory pieces are advancing, but the "big picture", how they all fit together, is still being drawn. Politicians are now stepping in to provide that vision.

The fusion of blockchain and AI in finance is not unique to Japan, countries around the world are exploring their own strategies. How is digital currency or blockchain finance developing in your country? What role is your government playing? We'd love to hear your perspective.
