How to Choose a Cryptocurrency Exchange: Top 5 International Platforms Recommended

Is It Illegal to Use Overseas Crypto Exchanges?

Understanding the legal status of using overseas crypto exchanges in Japan is crucial. In summary, it is not illegal for Japanese residents to use overseas crypto exchanges. While Japanese law requires crypto exchange operators to register with the Financial Services Agency (FSA), there are no specific legal restrictions preventing individuals from using overseas exchanges.

Legal Foundation

Japan’s crypto trading framework is established by the Payment Services Act. This law requires businesses running crypto exchanges to register with the Prime Minister. Importantly, these rules are directed at the operators, not at individual users.

This structure means unregistered crypto exchanges are prohibited from operating in Japan, but Japanese individuals can legally use overseas, unregistered exchanges for personal purposes. However, this interpretation is based on current law and could change, so users should always check for the latest regulatory updates.

Registration Status and Common Misunderstandings About Overseas Exchanges

Many overseas crypto exchanges are not registered with the FSA, which makes some Japanese users uneasy. In the past, major overseas exchanges have received FSA warnings and subsequently stopped serving Japanese residents. These events have contributed to the common misconception that using overseas exchanges is illegal.

Legally, however, individual Japanese users are not prohibited from using unregistered exchanges. The key issue is whether the exchange is actively soliciting business in Japan—for example, advertising or promoting yen deposits may be considered unregistered business activity.

On the other hand, if users independently access and use overseas services, this is recognized as their personal choice. However, since this “gray zone” may face stricter regulation in the future, it’s important for users to stay updated on regulatory trends.

Security Risks to Consider

When using overseas exchanges not registered with the FSA, users must recognize the associated security risks. FSA-registered exchanges in Japan must meet strict regulatory standards, ensuring a certain level of security. Unregistered overseas exchanges do not offer such guarantees, so users must assess risk themselves.

Key risks include hacking. Several overseas exchanges have suffered major hacks, resulting in the loss of user assets. There is also the risk of encountering scam tokens or fraudulent projects, which are sometimes listed at overseas exchanges with less rigorous screening.

There is further risk of sudden service suspension or bankruptcy. While Japanese exchanges must segregate customer assets, overseas unregistered exchanges are not held to this standard, so assets may be at risk if the exchange fails.

To mitigate these risks, thoroughly research the exchange’s track record, security protocols, and any history of incidents. Additionally, diversify your assets across multiple exchanges and use hardware wallets for long-term holdings to enhance risk management.

Key Factors When Choosing a Crypto Exchange

Choosing a crypto exchange requires evaluating several critical factors. Here are five essential points to consider:

1. Strong Security

Security should be your top priority. Since digital assets are held by the exchange, robust protection is essential. If you use an exchange with weak security, you face higher risks of hacking or unauthorized access.

Check for two-factor authentication (2FA), which adds a layer of login protection, and SSL encryption to secure all communications. Top exchanges store most client assets in cold wallets and only keep the minimum necessary in hot wallets.

Look for regular security audits, intrusion detection, and multi-signature wallets. Consider the exchange’s history—whether it’s experienced security incidents and how it responded.

2. Wide Range of Listed Assets

The number of crypto assets available is another key factor. While nearly all exchanges list Bitcoin and Ethereum, the variety of altcoins and new tokens varies widely.

Exchanges with a broad selection offer more investment opportunities and make portfolio diversification easier. You may also access new projects early, potentially increasing returns.

However, more assets can mean higher risk, as less reputable tokens might be listed. Don’t just look at quantity—check how strictly the exchange screens new listings.

Your required asset selection depends on your strategy. If you focus on major coins, fewer listings may suffice. If you want to invest in emerging projects or diversify, choose an exchange with a broad asset lineup.

3. Competitive Fees

Fee structure is essential for managing trading costs. Compare trading fees (usually a percentage of each transaction), and note the difference between maker (limit order) and taker (market order) fees—maker fees are often lower.

Consider spreads (the gap between buy and sell prices), especially for short-term trading. Order book-based exchanges typically offer tighter spreads than brokerage-style platforms.

Deposit and withdrawal fees also vary and can add up if you move funds frequently. Match the fee structure to your trading style—active traders should prioritize low trading fees, while long-term holders should watch deposit and withdrawal costs.

4. Platform Usability and Convenience

Ease of use matters, especially for beginners. A well-designed interface minimizes mistakes and missed opportunities.

Look for a simple, intuitive interface, as complex layouts can be confusing. A quality mobile app is crucial, as many users trade on the go—make sure it’s fast, stable, and user-friendly.

Check whether the exchange supports advanced order types (like stop orders and trailing stops) and offers robust charting tools for technical analysis. For some users, simple, clean charts may be preferable.

Japanese language support is vital for many users. Confirm that both the site/app and customer support are available in Japanese to ensure you can get help when you need it.

5. Reliability and Regulatory Compliance

Long-term reliability is fundamental. Consider how long the exchange has been in business and its user base and trading volume for signs of trustworthiness.

Transparency is also key—exchanges that publish due diligence or Merkle Tree proof-of-reserves reports are generally more trustworthy. Due diligence by independent parties on financial health and risk management helps users assess the platform’s soundness.

A Merkle Tree is a blockchain-based structure for verifying total customer assets. Regular proof-of-reserves publications show the exchange is managing assets properly.

Review any past security incidents and how the exchange responded—swift, responsible action is a good sign. Also, check for regulatory licenses in multiple countries. Even if not FSA-registered, exchanges meeting other countries’ standards may still be reliable.

Pros and Cons of Overseas Crypto Exchanges

Advantages of Overseas Crypto Exchanges

Overseas exchanges offer advantages not available domestically. Here are the main benefits:

1. Extensive Asset Selection

Leading overseas exchanges list hundreds or thousands of assets, opening up far more investment opportunities. Some platforms list over 2,900 tokens, while others have more than 700.

This variety lets you invest early in new projects—domestic exchanges’ strict listing standards can delay access, but overseas exchanges often list tokens sooner, allowing earlier entry and potentially higher returns.

Diversification is easier, reducing risk by spreading investments across sectors and asset types. You may also spot trends and invest in up-and-coming technologies before they go mainstream. However, lower-liquidity tokens require extra caution and research.

2. Lower Spreads and Fees

Overseas exchanges usually have tighter spreads and lower trading fees, thanks to higher liquidity. For instance, while domestic platforms may have spreads of several percent, overseas order book exchanges can keep spreads below 0.1% for major assets.

Trading fees often hover around 0.1% or lower, benefitting active traders. Some exchanges also offer discounts for holding their native tokens.

To maximize these benefits, use order book-style trading over brokerage-style, which tends to have wider spreads even overseas.

3. High Leverage

Overseas exchanges offer leverage of 10x, 50x, or even more, compared to a 2x cap in Japan. High leverage enables bigger positions with less capital, potentially amplifying profits.

However, losses are also magnified. Many overseas exchanges use a “zero cut” system, meaning users cannot lose more than their margin, reducing debt risk.

High leverage is best suited to experienced traders. Set leverage levels that match your risk tolerance and use sound risk management practices.

Drawbacks of Overseas Exchanges

Despite their benefits, overseas exchanges have downsides that users should consider:

1. Language Barriers

Many overseas exchanges primarily use English, and not all provide full Japanese support. Limited language support can make navigation, trading, and support difficult, especially for complex operations or urgent issues.

Prioritize exchanges with Japanese interfaces and customer support to minimize misunderstandings and communication challenges.

2. No Direct Yen Withdrawals

Unlike domestic platforms, overseas exchanges do not support direct yen deposits or withdrawals. You must buy crypto at a domestic exchange, transfer it overseas for trading, then send it back to cash out in yen.

This process takes time, adds trading and transfer fees, and exposes you to price volatility during transfers. Some overseas exchanges support credit card purchases, but fees are typically higher, so weigh cost and convenience.

3. Hacking Risks

Crypto exchanges are lucrative targets for hackers. Overseas exchanges are not supervised by Japan’s FSA and may have different security standards or asset management practices.

Major hacks have led to significant user losses, and compensation policies vary by exchange. Diversify holdings, use hardware wallets for long-term assets, and confirm the exchange’s security protocols before depositing funds.

4. Sudden Service Disruption

Overseas exchanges may suddenly stop serving Japanese users due to regulatory action, management decisions, or legal changes. This could happen with little notice, making it difficult to withdraw assets in time. Poor financial transparency further increases the risk of loss if an exchange fails.

Monitor regulatory developments, keep only necessary funds on exchanges, and use multiple platforms to reduce exposure if one becomes unavailable.

Understanding the Travel Rule Is Essential

The “Travel Rule” is a critical regulation for crypto transfers. It requires exchanges to share sender and recipient details to combat money laundering and terrorist financing, in line with FATF recommendations and Japanese law.

This rule has made transfers more complex for users, who must now provide additional information. Here’s what you need to know about its impact:

1. Required Transfer Details

When transferring crypto between domestic and overseas exchanges, you must provide personal and account details for both sender and recipient, including:

• Sender’s name (or business name)
• Sender’s account or customer ID
• Sender’s blockchain address
• Recipient’s name (or business name)
• Recipient’s account or customer ID
• Recipient’s blockchain address

Requirements and methods may differ by exchange, so confirm details before initiating a transfer. Input errors can result in delays or failed transfers, so accuracy is essential.

The rule also raises privacy concerns, as previously crypto transfers were more anonymous. Now, exchanges share detailed personal information—meant to prevent crime, but some users may be uneasy.

2. Interoperability Issues Between Solutions

Japanese exchanges typically use either TRUST or Sygna to comply with the Travel Rule, but these are not always compatible, which can block transfers between exchanges using different systems.

Check which solution your domestic and target overseas exchange use before transferring. Some exchanges support multiple solutions, but full interoperability is not yet achieved, so caution is needed.

If your target exchange does not support your domestic exchange’s protocol, you may have to use a different domestic provider or route the transfer differently, increasing effort and cost.

3. Restrictions on Transferable Assets

Not all assets can be transferred internationally, even if supported domestically. Technical limitations of Travel Rule solutions may prevent direct transfers of certain coins; you may need to convert to a supported asset like Bitcoin or Ethereum first, incurring extra fees and exposure to price changes. This also complicates tax reporting.

Always confirm which assets can be transferred via both your domestic and overseas exchanges before proceeding, and consult official lists or help pages as needed.

There is no trust asset protection—use caution and avoid large, long-term deposits.

Security: ★★★☆☆
Usability: ★★★★☆
Fees: ★★★☆☆

Conclusion: Choose Overseas Exchanges Carefully According to Your Needs

Overseas crypto exchanges provide a range of assets and advanced features unavailable domestically, making them attractive for investors seeking broader opportunities. Their strengths include asset variety, low trading costs, and high leverage.

However, they operate under different regulatory regimes, and users must pay close attention to security and asset protection. Carefully review each exchange’s strengths and risks, and select the platform that best fits your investment goals and style. For example, Exchange E is ideal for asset variety, while Exchange B stands out for copy trading.

Always take robust security measures, diversify assets across exchanges and wallets, and use hardware wallets for long-term holdings. Comply with regulations, such as the Travel Rule, and verify compatibility before transferring assets overseas. Stay informed about regulatory changes to respond quickly if your exchange’s status changes.
