Using overseas cryptocurrency exchanges is not prohibited by Japanese law. While current Japanese regulations require that crypto exchange operators register with the Financial Services Agency (FSA), there are no direct restrictions placed on individual users.
Japan’s Payment Services Act mandates that cryptocurrency exchange operators obtain registration from the Prime Minister to conduct business. This legislation primarily targets the “exchange operator” side, not the end user. As a result, running an unregistered exchange is illegal, but there are no legal constraints on individuals using unregistered overseas exchanges.
This distinction is essential for using overseas exchanges with confidence. However, legal compliance does not guarantee the safety of all overseas exchanges.
Many overseas cryptocurrency exchanges are not registered with Japan’s FSA, which can cause user concern. Historically, some exchanges have received directives from the FSA to restrict access by Japanese residents.
Such incidents have contributed to the misconception that “overseas exchanges are illegal.” In reality, Japanese individuals are not breaking the law by personally using unregistered foreign exchanges. The key is to evaluate each exchange’s reliability and security posture individually.
Overseas exchanges not registered with the FSA may carry security risks, including vulnerability to hacking or listing of fraudulent cryptocurrencies.
Before using an overseas exchange, thoroughly review its operational status, history of security incidents, and the security measures it employs. It’s wise to diversify assets across multiple exchanges and use cold wallets for long-term holdings as part of robust risk management.
Selecting an exchange requires a comprehensive evaluation of several critical factors. The following five points are especially important:
Security should be your top priority. Protecting client assets is non-negotiable in crypto trading, so it’s vital to confirm what security protocols the exchange implements.
Check for the following security features:
Also, review the exchange’s server stability, record of countering hacking attempts, and quality of customer support. Strong security measures provide greater peace of mind.
The range of available cryptocurrencies is a key consideration. While almost all exchanges support major tokens like Bitcoin and Ethereum, the breadth of altcoin offerings varies widely.
A diverse token lineup offers advantages such as:
For those seeking future opportunities, choose exchanges that list both major altcoins and promising new projects. However, remember that minor tokens may have limited liquidity—thorough due diligence is essential.
Fees are a critical factor when choosing an exchange, as even small differences can significantly impact long-term returns.
Key fee types include:
Compare fee structures across exchanges and select one that aligns with your trading style. For frequent traders, even minor fee differences can add up. Some platforms offer discounts for holding their native tokens, so factor in those benefits as well.
The intuitiveness of an exchange’s trading tools directly impacts efficiency and outcomes. Platforms with user-friendly interfaces enable stress-free trading.
Key usability factors include:
Simple interfaces are best for beginners, while advanced users may prioritize sophisticated charting and API connectivity.
Always verify the exchange’s reliability and operational transparency. To use overseas exchanges safely, check:
Enhancing Transparency with Due Diligence
Due diligence involves independent investigation and disclosure of project risks. This allows investors and counterparties to accurately assess risks, greatly improving transaction transparency. Reputable exchanges undergo regular due diligence and proactively publish their findings.
Merkle Trees for Transparency
Merkle tree structures enable hierarchical data verification on blockchains, quickly detecting tampering. This technology strengthens trust and transparency in asset management. Leading exchanges regularly publish Merkle tree-based proof of reserves.
Extensive Token Offerings
Overseas exchanges list far more tokens than domestic ones. The largest platforms support hundreds or thousands of cryptocurrencies, including emerging projects and buzzworthy assets unavailable in Japan.
This wide array of choices allows for:
However, a large selection may include tokens with low liquidity or reliability, so thorough research is essential.
Low Spreads and Competitive Fees
Overseas exchanges typically offer narrower spreads than domestic ones. The spread—the gap between buy and sell prices—affects your actual trading cost.
Fee advantages include:
This low-cost structure appeals especially to day traders. Long-term investors benefit less but still gain from low fees on asset transfers or periodic rebalancing.
High Leverage Trading
Overseas exchanges may support leverage far beyond Japan’s 2x cap—sometimes 100x or more—enabling large positions with limited funds.
Key features:
High leverage amplifies both profits and risks. Most platforms implement zero-cut systems to avoid debt risk, but loss of collateral remains possible. Use high leverage only with full awareness of the risks.
Language Barriers in Support
Some overseas exchanges only offer customer support in English. While Japanese support is increasing, it is not universal.
Language challenges include:
Basic trading is often intuitive, but language barriers may hinder problem resolution.
No Direct Yen Deposits or Withdrawals
Most overseas exchanges do not support direct deposits or withdrawals in yen. You’ll need to use a domestic exchange for these steps, which adds time and costs:
This process can be inconvenient for frequent fund transfers. Some exchanges offer credit card purchases for initial deposits, making the process simpler in some cases.
Hacking Risks
Overseas exchanges are not immune to hacks. Major incidents have occurred, resulting in customer asset losses.
Security recommendations:
Some exchanges offer insurance, but not all losses are covered. Personal risk management is crucial.
Service Suspension Risk
Overseas exchanges may suddenly suspend service for Japanese residents due to FSA warnings, business shifts, or regulatory changes.
Examples include:
Mitigation strategies include:
Since overseas exchange policies may change, stay alert for service updates and regulatory changes, and be ready to adapt.
The Travel Rule is an international requirement mandating that exchanges share sender and recipient details when transferring crypto assets. In Japan, the rule was introduced via amendments to the Act on Prevention of Transfer of Criminal Proceeds, targeting money laundering and terrorist financing.
This regulation now requires compliance by domestic exchanges and significantly impacts user transfer processes. Anyone using overseas exchanges must understand the Travel Rule.
When transferring crypto from a domestic to an overseas exchange, the Travel Rule requires you to provide:
Examples of required data:
Requirements vary by exchange. If information is incomplete, transfers may be rejected or delayed.
Domestic exchanges may use different Travel Rule solutions, such as TRUST or Sygna. Transfers may not be possible between platforms using incompatible systems.
Impacts include:
These restrictions make inter-exchange transfers more complex. Plan accordingly.
Even if a cryptocurrency is supported domestically, the Travel Rule may prevent its transfer to overseas exchanges.
Examples:
Before sending crypto abroad, check:
These restrictions add complexity, but proper preparation enables smooth transfers.

Overall ratings:
Overseas cryptocurrency exchanges provide access to a wide array of tokens and advanced trading features not found domestically, expanding investment options. Their advantages—broad token selection, competitive fees, and high leverage—are compelling for many investors.
However, these exchanges operate under different regulations and may not offer the same asset protection as domestic platforms. Users should understand that they bear full responsibility in the event of issues, as Japanese FSA oversight does not extend to these exchanges.
Recent regulations like the Travel Rule require compliance, including detailed information provision and verification of receiving platforms. While these requirements may seem cumbersome, they play an essential role in preventing money laundering and terrorism financing.
When evaluating overseas exchanges, carefully consider:
This guide compared leading overseas exchanges, highlighting their strengths, weaknesses, and risk management recommendations. Each platform has unique advantages; the best choice depends on your investment style and goals.
Beginners may prefer exchanges with robust Japanese support and simple interfaces. Advanced traders may prioritize sophisticated features and broad token selection. Long-term investors should focus on security and trustworthiness.
By choosing the right exchange and practicing sound risk management, you can maximize overseas investment opportunities. Never keep all assets on one exchange—diversify across platforms and use self-custody wallets for long-term holdings to reduce risk.
Crypto investing offers high-return potential, but carries significant risks. When using overseas exchanges, understand these risks and act responsibly.
Security, regulatory transparency, and user protection are top priorities. Evaluate cold/hot wallet separation, multi-signature authentication, proof of reserves, and trading volume as essential benchmarks.
Major exchanges vary in fee structures, user base size, regulatory environments, trading volumes, supported pairs, security, leverage options, and user interfaces. Compare each platform’s strengths before deciding.
Review licensing, security protocols, trading volumes, user feedback, and custody mechanisms. Key indicators include regulatory registration, two-factor authentication, cold wallet storage, and operational transparency.
Prioritize security, low fees, user-friendly interfaces, and robust protection. Select platforms with high trading volumes and a proven record of regulatory compliance.
Trading fees generally range from 0.1% to 0.5%. Withdrawal fees depend on the crypto asset and network, typically from a few cents to several dollars.
Risks include transparency and regulatory uncertainty, technical vulnerabilities, and market volatility. Verify platform reliability, implement strong security, and manage funds carefully.
Supported currencies and pairs depend on each exchange’s market strategy and resources. Some specialize in certain assets, and differences exist in listing standards, liquidity, and token selection. Choose according to your investment needs.
KYC involves submitting government-issued ID (passport, license, etc.) and official documents, uploading high-resolution scans, and completing facial verification. Review takes a few days; full trading access is enabled after approval.
Always use the official website, confirm wallet addresses, protect your private keys, and enable two-factor authentication. Avoid unauthorized plugins and use secure network connections.
Many platforms prohibit registration by users from China, though some exceptions exist. Always check platform terms of service before registering.
