Trying to launch a crypto exchange in Japan is not like starting a business in most other countries. You can't just launch a website and start trading. If you do, you're not just risking a fine; you're risking actual jail time. Japan has one of the tightest regulatory grip on digital assets in the world, and the centerpiece of this system is the PSA registration is the mandatory licensing process under the Payment Services Act for any entity providing crypto-asset exchange services in Japan. If you want to operate legally, you need to understand that the Japanese government views consumer protection as a non-negotiable priority.
What Exactly is a CAESP?
To navigate the law, you first need to know the terminology. The Financial Services Agency (or FSA) doesn't just call them "exchanges." They use the term Crypto Asset Exchange Service Provider, often shortened to CAESP. Essentially, if your business involves buying or selling crypto assets as a professional service, you are a CAESP.
Under the Payment Services Act (PSA), a "crypto asset" is defined as a payment mechanism not denominated in fiat currency that can be used to pay unidentified people. This means Bitcoin, Ethereum, and most altcoins fall under this umbrella. However, there is a clear line: if an asset is denominated in Japanese Yen or another fiat currency (like some prepaid e-money cards), it isn't a crypto asset under the PSA. Similarly, if a token behaves like a security-meaning it offers investment-like returns-it falls under the Financial Instruments and Exchange Act (FIEA), which is an even steeper mountain to climb in terms of licensing.
The Price of Non-Compliance
Operating without a license in Japan is a serious criminal offense. Under Article 107 of the Amended PSA, those caught running an unregistered exchange can face fines up to JPY 3 million. More importantly, the law allows for imprisonment. As of June 1, 2025, the legal system transitioned this to "confinement punishment" (koukin-kei) under the updated Penal Code. This isn't just a slap on the wrist; it's a deterrent designed to keep fly-by-night operators out of the Japanese market.
Hard Requirements for Registration
Getting your registration isn't about filling out a simple form. It's about proving your company is stable, secure, and legally sound. Here is what you actually need to bring to the table:
- Corporate Structure: You must be a stock company (kabushiki-kaisha). If you are a foreign company, you can't just open a branch. While the law mentions branches, the FSA has historically only approved subsidiaries. You'll need to set up a local Japanese company with local representatives.
- Financial Muscle: You need a minimum capital of JPY 10 million. Beyond that, your net assets must remain positive. The FSA wants to know that if things go south, you have a financial cushion.
- Organizational Rigor: You have to demonstrate a clear internal structure. This means having dedicated compliance officers and systems that ensure every trade follows Japanese law.
- Asset Segregation: This is the "golden rule" in Japan. You must have a foolproof method to keep customer funds completely separate from company operating funds.
| Requirement | Minimum Standard | FSA Expectation |
|---|---|---|
| Capital | JPY 10 Million | Positive net assets at all times |
| Entity Type | Kabushiki-kaisha | Local subsidiary for foreign firms |
| Cold Wallet Storage | 95% of user assets | Offline, secure, and ring-fenced |
| Review Time | ~6 Months | Extensive documentation provided |
The Application Process: What to Expect
If you've gathered your capital and set up your company, the clock starts. The official review process usually takes about six months, but that's just the time the FSA spends looking at your papers. The actual preparation can take much longer. You'll need to submit a massive dossier including:
- Your trade name, registered address, and a full list of directors.
- A precise list of every single crypto asset you plan to support. You can't just say "all coins"; you must specify each one.
- Detailed blueprints of how you provide the service and how users interact with the platform.
- A map of all outsourcing arrangements. If you use a third-party cloud provider or KYC service, the FSA wants to know who they are and how they are managed.
- A comprehensive plan for the segregation of assets, showing exactly how user coins are protected.
Strict Consumer Protections and Daily Operations
Once you have the license, the work doesn't stop. The PSA imposes strict daily operational rules. One of the most famous is the 95% cold wallet rule. To prevent another Mt. Gox scenario, the government requires that at least 95% of all customer crypto assets be kept in offline wallets. This significantly limits how "liquid" an exchange can be, but it makes the system incredibly safe for the user.
Marketing is also under a microscope. You can't use "hype" language. Promising quick profits or using vague, glossy claims to lure in investors is a fast track to an FSA audit. Everything must be transparent and evidence-backed. To help manage this, the FSA works with self-regulatory bodies. The Japan Virtual Currency Exchange Association (JVCEA) handles most exchange rules, while the Japan Security Token Offering Association (JSTOA) focuses on the more complex world of security tokens and crowdsourcing.
The Trade-off: High Barriers vs. High Trust
Is this system too strict? For a small startup, maybe. The JPY 10 million capital requirement and the cost of building a compliance infrastructure create a massive barrier to entry. This naturally favors big banks and well-funded fintech firms. However, there is a massive upside: legal clarity.
Unlike in some jurisdictions where the rules change every week, Japan has clearly stated that cryptocurrencies are legal property. By following the PSA, an operator knows exactly where the lines are. This certainty attracts institutional investors who are terrified of "regulatory risk." If you are a registered CAESP, you have a seal of approval that tells the world your business is legitimate.
Can a foreign company operate in Japan without a local subsidiary?
In practice, no. While the PSA allows for branches, the Financial Services Agency (FSA) has consistently required foreign entities to establish a local subsidiary in the form of a kabushiki-kaisha to be granted CAESP registration. You must have a local presence and representatives in Japan.
What happens if I list a coin that wasn't in my registration?
Listing assets not approved by the FSA or vetted by the JVCEA can lead to administrative orders or penalties. The registration process requires you to specify the assets you will handle, and adding new ones typically requires a review process through the self-regulatory associations.
How much capital do I actually need to start?
The absolute minimum capital required by law is JPY 10 million. However, you should budget significantly more for the actual setup, as you'll need to pay for local legal counsel, compliance officers, and the technical infrastructure required to meet the 95% cold storage mandate.
What is the difference between PSA and FIEA registration?
The PSA (Payment Services Act) is for general "crypto assets" used as a means of payment or exchange. The FIEA (Financial Instruments and Exchange Act) applies to tokens that act like securities (equity, debt, or investment contracts). FIEA licenses are generally harder to get and involve much heavier oversight because they deal with traditional financial instrument laws.
How long does the registration process take?
The official review period by the FSA is roughly six months. However, this is only the final stage. The time spent incorporating your company, developing your internal compliance systems, and preparing the massive amount of required documentation can easily add several more months to the timeline.
Next Steps for Applicants
If you are planning to enter the Japanese market, don't start with the application. Start with a compliance audit. Map out your current asset segregation methods and see if they meet the ring-fencing standards required by the PSA. If you are a foreign entity, your first move should be consulting with a Japanese legal firm to incorporate your kabushiki-kaisha. Only after your corporate structure is legal and your capital is deposited should you approach the FSA for registration.
Comments
The strictness of the FSA is exactly why Japan is a safer bet for institutional money than the wild west of some other jurisdictions.
