Is using overseas cryptocurrency exchanges illegal in Japan? In short, Japanese residents are not prohibited from using overseas cryptocurrency exchanges. While current Japanese law requires exchanges to register with the Financial Services Agency (FSA), there are no direct regulations targeting individual users.
Japan’s Payment Services Act requires cryptocurrency exchange operators to register with the Prime Minister, but this law primarily regulates the service providers, not the users. Operating an unregistered exchange is illegal, yet individuals are not legally restricted from accessing services offered by unregistered exchanges.
Even so, users must trade at their own risk. Exchanges operating outside FSA oversight may not provide sufficient protection in the event of disputes, so caution is advised.
Many overseas cryptocurrency exchanges are not registered with Japan’s FSA, which can cause concern among Japanese users. In some cases, the FSA has instructed exchanges to restrict local access for Japanese residents.
These cases sometimes lead to the misconception that “overseas exchanges = illegal,” but the law does not prohibit Japanese individuals from personally using unregistered exchanges. What matters most is to carefully review each exchange’s operations and security systems, understand the risks, and proceed with informed judgment.
Exchanges not registered with the FSA may present security risks, including vulnerability to hacking and the potential for fraudulent tokens.
When using overseas exchanges, you should confirm the following:
Assess these factors as a whole and choose an exchange you can trust—this is the foundation of safe trading.
When selecting a cryptocurrency exchange, several critical criteria deserve attention. Below, we detail five essential factors to consider.
Security should be the top priority. Protecting client assets is fundamental, so verify which measures the exchange implements.
Key security features include:
Also check for robust server stability, comprehensive anti-hacking protections, and responsive support. If past security incidents occurred, the exchange’s subsequent response and improvements are important indicators. Strong security creates a foundation for worry-free trading.
The range of available tokens is another key factor. While most exchanges support Bitcoin and Ethereum, the selection of other altcoins varies.
Benefits of a broad selection:
Choose exchanges that offer both major and minor coins for greater investment opportunities. However, more tokens do not automatically mean a better exchange—always check liquidity and reliability as well.
Fees are a crucial consideration. They have a significant impact on long-term trading costs, so close comparison is essential.
Key fee categories:
Lower fees mean lower operating costs. Compare multiple exchanges to determine which offers the best value for your trading style. Even small differences can add up for active traders. Also consider fee discounts for high volume traders or proprietary token holders.
Trading tool usability is also critical. Smooth, intuitive operation supports trading success.
Usability criteria include:
Simpler exchanges are best for beginners, while advanced traders should look for robust analysis and automation tools. Match your choice to your trading style for long-term results.
Reliability is essential. For safe overseas trading, select exchanges with transparent operations and strong compliance.
Reliability checklist:
Due Diligence for Transparency
Due diligence involves independent investigation of risks related to a company or project, with public disclosure of findings. This process helps investors accurately assess risks and enhances transparency. Reliable exchanges publish due diligence results regularly.
Merkle Tree for Transparency
The Merkle tree structure enables efficient and secure verification of blockchain data integrity. Tampering is quickly detected, strengthening confidence in transactions and asset management. Exchanges using Merkle tree for reserve proof show commitment to asset protection.
Extensive Token Selection
Major overseas exchanges list thousands of cryptocurrencies—far more than domestic exchanges.
Advantages of a broad selection:
However, some coins lack liquidity and may be highly volatile, so thorough research is essential before investing.
Lower Spreads and Fees
Overseas exchanges generally offer tighter spreads, lowering trading costs for active traders. Spread is the difference between buy and sell prices; narrower spreads reduce effective costs.
Cost-saving benefits:
Long-term holders may see limited advantage, but active traders can realize significant savings.
High Leverage Trading
Overseas exchanges allow leverage up to 100x or more, compared to the 2x limit domestically. Leverage lets traders pursue outsized gains with modest capital, but also raises risk of losses.
High leverage pros and cons:
Zero-cut systems automatically close positions before losses exceed margin, eliminating margin call risk typical of domestic exchanges. Still, poor risk management can result in rapid loss of funds, so caution is crucial.
Support Language Limitations
Some overseas exchanges offer support only in English. While basic trading is unaffected, inquiries may require translation tools.
Language barrier risks:
Recently, more exchanges are offering Japanese support, but full support remains limited. If language is a concern, select exchanges with robust Japanese language options.
No Direct Japanese Yen Withdrawals
Direct withdrawals to Japanese bank accounts are not available—you must use a domestic exchange as an intermediary, adding steps and potential fees.
Withdrawal process:
This process involves transfer fees and time delays. The travel rule may also require detailed information during transfers.
Hacking Risks
Hacking remains a risk at overseas exchanges, with several major incidents reported. Protect your assets by following these best practices:
While hacking risk cannot be eliminated, strong security practices can minimize potential losses.
Risk of Sudden Service Suspension
Overseas exchanges may suspend service to Japanese users due to FSA warnings or business challenges. Some major platforms have closed Japanese operations or blocked local access.
Prepare for service disruptions:
Because Japanese user support is unstable, always be aware of regulatory changes and service suspensions, and be ready to adapt.
The travel rule requires exchanges to share sender and recipient details during crypto transfers. Japan recently introduced this rule to combat criminal proceeds and terrorist financing, impacting users of domestic exchanges.
When sending crypto from domestic to overseas exchanges, you must provide detailed sender and recipient information.
Required information examples:
Requirements vary by exchange, so confirm in advance and prepare all necessary information. Missing details may result in transfer rejection or delays.
Domestic exchanges use various travel rule solutions, and incompatibility may prevent transfers between different platforms.
Main solutions:
Foreign exchanges may use different solutions as well. Always confirm compatibility before initiating a transfer, and consider alternative routes if needed.
Even supported cryptocurrencies may be restricted by the travel rule.
Examples of transfer restrictions:
Check which tokens are supported before sending funds. If needed, exchange to a supported coin prior to transfer. The travel rule is evolving, so always stay updated.
Exchange A is a major Asia-based platform fully supporting Japanese language and offering over 300 tokens, making it user-friendly for Japanese traders.
Exchange A supports leverage trading up to 100x, allowing large positions with relatively small capital. Its zero-cut system automatically closes positions before losses exceed margin, helping users manage risk effectively.
Main features:
No Direct Yen Deposits or Withdrawals
Direct deposit or withdrawal in yen is not supported, so you must buy crypto at a domestic exchange and transfer it, incurring additional fees and steps.
No Trust Asset Protection
Since the exchange is not registered with the FSA, assets are not protected by trust. In case of bankruptcy, your assets may not be recoverable. Move large holdings to a self-custody wallet regularly.
While leverage, token diversity, and Japanese support are major strengths, the lack of direct yen transactions and trust protection pose risks. Understand these points and trade at your own risk.

Additionally, the exchange prioritizes asset protection, publicly disclosing proof of reserves with a reserve ratio over 200%, highlighting its commitment to safeguarding user funds.

Based in Asia, the exchange may be subject to political and regulatory changes. Some countries have strict crypto policies, and expanded regulation may pose risks. In the past, services for Japanese users have been temporarily restricted, so monitor regulatory developments closely.

Overseas cryptocurrency exchanges offer broad token variety and advanced trading functions not found in domestic platforms, making them attractive for investors seeking diversification. However, different regulations mean you must pay close attention to security and asset protection.
Key points for using overseas exchanges:
Compliance with travel rule and similar regulations requires proper information sharing and transfer destination checks. Using multiple exchanges and combining domestic and overseas platforms can help diversify risks and optimize trading.
This article compared popular overseas exchanges and explained how to manage risks and maximize their benefits. Each exchange has its own strengths and weaknesses; select one that fits your trading style and investment goals.
By choosing the right platform, implementing rigorous security, and preparing for risks, you can fully leverage overseas exchanges’ investment opportunities. Always stay informed and act with caution for successful trading.
Review robust security practices, regulatory approval, trading volume, fee structure, and transparency in identity verification. Confirm multi-signature and cold wallet features for security.
Overseas exchanges offer hundreds of currencies, more flexible regulations, and lower fees. Domestic exchanges operate under strict FSA oversight, provide higher safety, and support direct yen deposits and withdrawals. Overseas platforms also offer advanced API and smart contract integration.
Check for regulatory approval, two-factor authentication, asset insurance, transparent security disclosures, independent audits, reliable third-party reviews, and sound fund management.
Spot trading fees are typically around 0.1%. Fees are calculated per transaction—for example, a $10,000 trade would cost $10. Some exchanges offer 0% Maker fees.
Beginner-friendly overseas exchanges offer low minimum trades and a wide range of rare coins. Note that Japanese support is often limited, and lack of FSA approval may impact reliability.
