Is it illegal to use overseas cryptocurrency exchanges in Japan? In short, Japanese residents are not prohibited from using overseas crypto exchanges. While Japanese law requires domestic exchanges to register with the Financial Services Agency (FSA), there are no direct regulations restricting individuals from accessing overseas exchange services.
To clarify, understanding Japan's legal framework for crypto assets is essential. The Payment Services Act requires crypto asset exchange operators to register with the Prime Minister. This law primarily targets service providers—meaning the operators of exchanges—and does not impose direct limitations on users.
Therefore, operating an unregistered cryptocurrency exchange within Japan is illegal, but individuals can legally use the services of unregistered overseas exchanges. However, "legal usage" does not equate to "guaranteed safety."
Many overseas crypto exchanges lack FSA registration, which causes concern for Japanese users. Legally, Japanese individuals are not prohibited from personally using unregistered exchanges. The key point is that exchanges unregistered with the FSA do not fall under the protection of Japanese financial regulations.
Overseas exchanges without FSA registration may pose security risks, including hacking, fraudulent tokens, sudden service suspensions, and inadequate asset protection. When using overseas exchanges, always verify their operational status, security measures, incident history, and user reviews.
Selecting a cryptocurrency exchange requires a comprehensive evaluation of several factors. Don't judge based solely on low fees or a wide selection of tokens. Review the following five points to ensure a secure and efficient trading environment.
Security infrastructure should be your top priority. Asset protection is critical, and you must verify the specific security measures the exchange employs.
Confirm the implementation of these security controls:
Choosing exchanges with multiple robust security measures significantly improves asset safety.
The number of tokens offered is a key consideration. While nearly all exchanges list Bitcoin and Ethereum, the availability of altcoins and new tokens varies widely.
A diverse selection provides these advantages:
However, more tokens aren't always better. Fraudulent projects and worthless tokens may be present, so always verify project credibility before investing.
Fees are a critical factor in choosing an exchange. Over time, fee differences can significantly impact returns, especially for active traders. Review these key fee types:
Lower fees help reduce overall trading costs and boost efficiency. Even small differences add up for frequent traders.
Platform usability is critical. Smooth operation directly affects trading outcomes. Assess the following:
To avoid missing opportunities, choose platforms with fast order execution.
Finally, verify reliability and transparency. To safely use overseas exchanges, review these aspects:
Evaluating these factors helps identify trustworthy exchanges.
Using overseas exchanges offers advantages not available domestically, but also introduces unique risks and drawbacks. Here are the major pros and cons to consider.
Overseas exchanges typically list far more crypto assets than domestic ones. Some major platforms support hundreds or thousands of tokens, compared to dozens on Japanese exchanges.
This broad selection enables:
Investing in coins and tokens unavailable domestically is especially attractive for high-risk, high-reward investors.
Overseas exchanges often offer narrower spreads than domestic platforms. The spread is the difference between buying and selling prices—the tighter the spread, the lower your trading cost.
Key benefits include:
Many platforms also offer fee discounts based on trading volume or proprietary token holdings, helping further reduce costs over time.
Many overseas exchanges offer leverage up to 100x, compared to the domestic cap of 2x. This allows traders to control larger positions with less capital.
Key benefits include:
Note that higher leverage increases both profit and loss potential. Many overseas platforms use "zero-cut" systems, which automatically close positions to prevent losses beyond your deposit, eliminating the risk of debt—a feature not offered by domestic exchanges.
Some overseas exchanges only provide customer support in English. While more platforms are adding Japanese, not all offer full native support.
Main challenges include:
While normal trading is usually unaffected, you may need translation tools or English proficiency for inquiries.
You cannot directly withdraw funds from overseas exchanges to Japanese bank accounts because they do not interface with Japan's banking system.
The typical process:
Main drawbacks:
This is a necessary limitation, so plan accordingly.
Overseas exchanges face hacking risks similar to domestic ones. Several major platforms have experienced hacks resulting in asset losses.
Mitigation strategies:
Combining these precautions is recommended for asset protection.
Overseas exchanges may suspend service for Japanese users due to regulatory warnings, business changes, or shifts in the regulatory environment. Historically, some platforms have withdrawn from Japan or stopped serving Japanese accounts.
Main risks include:
Japanese support can be unstable, so always monitor for service suspension notices and regulatory updates. Diversifying across multiple exchanges helps manage this risk.
The Travel Rule is an international standard requiring exchanges to share sender and recipient details when transferring crypto assets. Its purpose is to prevent money laundering and terrorist financing, and it is being adopted worldwide.
Japan has introduced the Travel Rule through amendments to the Act on Prevention of Transfer of Criminal Proceeds. As a result, transfers between domestic and overseas exchanges now require detailed information, and users must comply with these new regulations.
Transfers from domestic to overseas exchanges require notification of sender and recipient details. Examples of required information:
This information is sent automatically via the exchange's system. If the overseas exchange cannot receive it, the transfer may be rejected.
Domestic exchanges use various Travel Rule solutions, such as TRUST and Sygna, to securely communicate transfer data. These solutions may not be mutually compatible.
Main issues:
Before using overseas exchanges, confirm which Travel Rule solution they support and ensure compatibility with your domestic platform.
Even if a crypto asset is supported domestically, transfers may be blocked under the Travel Rule if the solution only supports specific coins.
Examples:
Before sending assets to an overseas exchange, check with your domestic exchange to confirm transfer eligibility under the Travel Rule.

As with all exchanges, assets may not be protected if the platform fails. Don’t leave large sums on the exchange; regularly move holdings to cold wallets. The huge number of tokens means scams and worthless coins may be present—always check project credibility, whitepapers, and team backgrounds before investing.

Overseas crypto exchanges offer diverse tokens and advanced features not found in Japan, making them valuable for expanding investment options. Large token selections, low fees, and high leverage are compelling advantages.
However, overseas exchanges operate under different regulations, so carefully review their security and asset protection. Not being FSA-registered means there’s no regulatory safety net, and assets may be at risk in case of failure.
When choosing an overseas exchange, evaluate these factors:
To comply with regulations like the Travel Rule, provide accurate information and verify transfer eligibility. Transfers between domestic and overseas exchanges now require more detailed data—be ready for this new standard.
For risk management, take these steps:
By choosing the right exchange and managing risks, you can maximize investment opportunities. Overseas exchanges offer unique opportunities, but also unique risks. Select platforms that fit your goals, risk tolerance, and trading style to achieve secure, efficient crypto trading.
Prioritize security and regulatory compliance, high trading volume, low fees, user reviews and reliability, and robust support. Security and compliance should be your top considerations.
Key differences include the number of supported currencies, fee structures, security standards, user interface quality, and regulatory status. Features like trading volume, derivatives, and support quality also vary.
Main risks are hacking, phishing, and asset theft. Protect yourself by enabling two-factor authentication, setting strong passwords, changing them regularly, monitoring account activity, and storing some assets in cold wallets.
All profits from overseas exchanges are treated as "miscellaneous income" and must be declared to Japanese tax authorities. File your taxes and pay the required income tax based on your earnings.
It depends on your goals. Overseas exchanges offer higher trading volumes and lower fees, while domestic exchanges provide stronger asset protection and regulatory oversight. Beginners and safety-focused users should choose domestic exchanges; those prioritizing trading volume may prefer overseas platforms.
Review tiered fee systems based on trading volume, discounts for holding platform tokens, deposit/withdrawal fees, and differences between spot and derivatives trading fees. Consider how fee reductions for higher trading volumes can cut costs over time.
