Japan was the first major economy to put crypto exchanges under a registration regime, and it did so after living through two of the industry's most damaging exchange failures. The result is a market with strict custody and listing controls, a strong gaming and IP industry exploring Web3, and a government that has, since around 2022, explicitly promoted Web3 as a policy goal.
How the rules evolved
Mt. Gox, once the dominant bitcoin exchange, collapsed in Tokyo in 2014. In response, Japan amended its Payment Services Act and, from April 2017, required exchanges to register with the Financial Services Agency. Months after the regime started, the Coincheck hack of January 2018 exposed weak hot-wallet practices and triggered a wave of inspections and business improvement orders. Rules tightened again: the legal term became "crypto assets", customer assets must be segregated with the large majority held in cold storage, and crypto derivatives and security tokens moved under the Financial Instruments and Exchange Act.
The lesson repeated in 2024, when a large theft from DMM Bitcoin led to that exchange winding down and transferring customer accounts to another operator. Japanese regulators therefore look closely at key management, and any team building custody or exchange systems for Japan should expect detailed scrutiny of wallet architecture.
The current landscape
Crypto asset exchange service providers
Exchanges, brokers and custodians serving Japanese residents must register with the FSA as crypto asset exchange service providers. Requirements include capital, segregation of customer assets, cold storage, AML and Travel Rule compliance, and system risk management. Foreign platforms cannot simply serve Japanese users from abroad; several have received FSA warnings for doing so.
The JVCEA
The Japan Virtual and Crypto assets Exchange Association is the FSA-certified self-regulatory organization. Registered exchanges are members, and the JVCEA reviews tokens before they can be listed, along with advertising and operational rules. Historically this made Japanese listings slow and selective; the association introduced streamlined procedures for tokens already handled by multiple members. If your business model depends on a Japanese exchange listing, budget time for this process.
Stablecoins
Amendments effective in June 2023 defined fiat-backed stablecoins as electronic payment instruments and limited issuance to banks, registered fund transfer service providers and trust companies, with separate registration for intermediaries that distribute them. The first licensed yen-denominated stablecoins have since reached the market. Algorithmic stablecoins are not treated as electronic payment instruments.
Security tokens and DAOs
Security tokens are "electronically recorded transferable rights" under securities law. Japan has an active security token market, much of it tokenized real estate and bonds distributed by securities firms, and the Osaka Digital Exchange has operated a trading venue for them. Japan also amended rules in 2024 to make it practical for a godo kaisha (a type of LLC) to issue token-based membership interests, a route some projects use as a DAO wrapper.
Tax
Individuals' crypto gains have generally been taxed as miscellaneous income at progressive rates that can reach about 55% combined, a long-standing complaint of the industry. Corporate tax rules were eased in 2023 and 2024 so that companies are not taxed on unrealized gains on certain tokens they issue or hold long term. The FSA has proposed moving crypto assets closer to securities regulation, which would open the door to a flat tax on gains; check whether those changes have been enacted.
The ecosystem and talent
Japan's distinctive strength is IP: games, anime, manga and entertainment companies with global fan bases. Large game publishers have experimented with blockchain games, gaming-oriented chains such as Oasys emerged, and Sony launched the Soneium network in 2025. Astar Network, founded in Japan, built ties with Japanese enterprises. If you are planning in this space, see blockchain game development and Astar NFT marketplaces.
Engineering talent is concentrated in Tokyo, with some in Osaka and Fukuoka. Japan has strong backend and game engineers, but fewer experienced smart contract and security specialists, and many work primarily in Japanese. Salaries for software engineers are generally below US levels, though bilingual senior engineers command a premium.
Choosing a development partner
Language and business culture matter more in Japan than in most markets. Enterprise and regulated clients expect detailed specifications, thorough documentation in Japanese, and a vendor that will remain accountable for years. A Japanese partner, or a foreign team with a Japanese project lead, is close to essential for regulated products and for enterprise sales. Remote foreign teams work well for protocol and smart contract work for global audiences.
Questions to ask
- Have you built systems for an FSA-registered exchange or custodian, and what did inspections examine?
- How do you implement cold storage ratios and segregation reporting?
- Can you deliver specifications, test reports and UI in Japanese?
- Do you have experience with the JVCEA listing review or with security token issuance through a securities firm?
For exchange systems see crypto exchange development; for tokenized property, the most common Japanese STO, see real estate tokenization.
Frequently asked questions
Can a foreign exchange serve Japanese users?
Not without FSA registration. Serving Japanese residents while unregistered has led to public warnings against several overseas platforms.
How long does a Japanese token listing take?
It varies with the token and the exchange, and new tokens without existing Japanese listings face the fullest review. Plan in months, not weeks.
Is Japan friendly to Web3 games?
The government has promoted Web3, and major publishers have experimented, but games involving tokens must still respect gambling, prize and crypto asset rules. Get advice on rewards design.
Can I issue a yen stablecoin as a startup?
Only through the permitted issuer types, such as a bank, trust company or registered fund transfer service provider, which in practice means partnering with or becoming a licensed entity.
