Japan’s fintech sector is entering a new phase. Backed by government growth strategies, regulatory reform, and structural macroeconomic shifts, the country offers a distinctive opportunity for international startups and investors. This article provides an overview of what global entrepreneurs should know.
Japan has one of the most comprehensive fintech regulatory frameworks in the world. The Financial Services Agency (FSA) oversees licensing for banking, payment services, crypto-asset exchanges, and electronic payment instruments (including stablecoins). The approach is rule-based and detail-oriented, with specific licensing requirements for each business category. Unlike jurisdictions that rely on principles-based guidance, the framework provides regulatory clarity and long-term predictability for market participants.
While Japanese law permits branch office registration of a foreign corporation, establishing a local entity (typically a Kabushiki Kaisha) is more common in practice. Municipalities including Tokyo, Osaka, Fukuoka, and Sapporo offer business support programs for foreign startups, providing assistance with incorporation, a fundamental understanding of doing business in Japan, and local networking. The FSA operates a Fintech Support Desk for consultation on financial laws under its jurisdiction. Japan also offers two sandbox mechanisms: the Cabinet Office’s Regulatory Sandbox (not limited to financial services) and the FSA’s FinTech Proof-of-Concept Hub.
Japan was among the first to legally define crypto-assets (2017) and to create a stablecoin dealer registration regime under the amended Payment Services Act (2023). In AI, the government has adopted a pro-innovation stance.
Core compliance requirements include: AML/KYC obligations (Japan is a FATF member with a progressively strengthened AML/CFT regime including sanctions screening); personal data protection under the APPI, particularly regarding cross-border transfers (note: as of late February 2026, an APPI amendment bill is increasingly likely to be submitted to the Diet, with potential effect from 2027 onward); and outsourcing governance, with robust oversight of third-party providers required. On the international front, Japan has championed DFFT (Data Free Flow with Trust) at the G7 and established the Institutional Arrangement for Partnership (IAP) as a multilateral framework for trusted cross-border data flows—an initiative directly relevant to fintech companies handling customer data across jurisdictions.
Economic security legislation imposes resilience requirements primarily on major financial institutions and very large-scale fintech operators. More broadly relevant is the Foreign Exchange and Foreign Trade Act (FEFTA): foreign investors in companies in designated sectors (shitei gyōshu)—including software and information processing services—may need to submit prior notifications. The regulatory trend is toward stricter scrutiny, though the IT-sector notification scope, criticized as overly broad since 2019, is expected to be partially rationalized.
Under Banking Act amendments, licensed fintech firms can access bank APIs as “Electric Payment Service Providers.” Approximately 130 of 138 major banks have published open APIs, with expansion to credit cards under discussion and further extension to securities, insurance, and other cashless methods being explored. This broadening of the API ecosystem is expected to create new entry points for fintech companies across multiple financial verticals.
Japan’s cashless payment ratio has surpassed 40% and continues to grow rapidly—a remarkable shift for a country historically known for its cash-oriented culture. The Zengin network—the domestic interbank funds transfer system operated by the Japanese Bankers Association—underpins this ecosystem and supports real-time settlement. Notably, UK-based Wise has connected to Zengin without a banking license, demonstrating the system’s openness to foreign fintech players meeting regulatory requirements. The expanding cashless ecosystem positions Japan as an increasingly attractive market for payment innovators.
Crypto-asset exchanges must register with the FSA under strict asset segregation and custody rules. The 2023 amended Payment Services Act created the “Electronic Payment Instruments” category for stablecoins. Yen-pegged JPYC and dollar-pegged USDC distribution have already been realized, with further initiatives underway including stablecoin projects by Japan’s three mega-banking groups. STOs are regulated under the Financial Instruments and Exchange Act, with a growing market for tokenized bonds and real estate. Osaka hosts ODX (Osaka Digital Exchange), a dedicated security token marketplace. These developments reflect Japan’s position as one of the most advanced jurisdictions for regulated digital asset infrastructure.
The Bank of Japan is also conducting a CBDC pilot program exploring the feasibility of a digital yen, signaling active preparation for future digital currency scenarios that may create both competitive dynamics and collaboration opportunities for private-sector providers.
Recent reforms focus on expanding access to unlisted equity markets: new intermediary frameworks for unlisted share transactions, secondary markets for earlier startup liquidity, refined SPV and crowdfunding regimes, and disclosure regulation reviews to reduce compliance burdens for smaller issuers while maintaining investor protection. For fintech companies operating in wealth management, investment platforms, or alternative finance, these reforms open new avenues in what has traditionally been a heavily intermediated system.
Japan’s technology strategy emphasizes “Physical AI”—integrating AI with real-world operations—as a national priority. The FSA notably emphasizes not only AI-use risks but also the risk of failing to adopt AI. An AI Promotion Act under preparation avoids rigid prescriptive regulation in favor of flexible, responsible adoption. Internationally, Japan launched the Hiroshima AI Process during its 2023 G7 presidency, establishing guiding principles and a code of conduct for advanced AI systems.
On digital identity, eKYC is widespread across financial services. The government promotes the My Number Card—a PKI-enabled national ID held by approximately 100 million people—as a primary verification tool. Smartphone integration is progressing and a next-generation card is planned for government rollout, offering fintech companies streamlined onboarding, stronger authentication, and reduced compliance friction for both domestic users and the growing foreign resident population.
