Before you start trading crypto assets, it's crucial to choose a trustworthy exchange. Overseas exchanges offer several compelling advantages over domestic platforms, including a broader selection of tokens, lower trading fees, and a wide variety of services.
When evaluating overseas exchanges, you should consider multiple factors, such as security protocols, trading fees, the number of supported tokens, user interface usability, and whether Japanese language support is available. In recent years, as the global crypto asset market expands, many overseas exchanges have been actively entering the Japanese market, making these platforms increasingly accessible for Japanese investors.
Each major overseas crypto exchange has its own unique strengths and characteristics. Below, we provide an in-depth look at the features of representative global platforms.
Some large international exchanges list more than 700 types of crypto assets, providing a broad selection—from major coins like Bitcoin and Ethereum to lesser-known altcoins. These platforms offer industry-leading low trading fees, typically in the 0.02% to 0.1% range, and often provide additional discounts for users who hold native platform tokens.
On the security front, these exchanges deploy best-in-class measures, such as two-factor authentication, cold wallet storage, and support for hardware wallets. Some have never suffered a security breach. They also provide support in over 20 languages, including Japanese, and operate in more than 160 countries worldwide, reflecting their aggressive global expansion.
Certain overseas exchanges offer high-leverage trading—up to 100x or even 1000x—making them popular with traders seeking large returns on small investments. These platforms provide diverse options, such as futures and perpetual contracts, and employ a maker-taker fee model that rewards liquidity providers with rebates.
They also offer a comprehensive suite of trading tools, including industry-standard platforms like MT4 and MT5, alongside proprietary analytics and charting tools to meet the needs of traders focused on technical analysis.
Some newer exchanges have introduced innovative features such as social trading, copy trading, and AI-driven trading. These platforms enable novice investors to follow the strategies of professional traders or automate their own trades, significantly lowering the barrier to entry.
Additionally, they actively roll out value-added services beyond standard trading, such as NFT marketplaces, proprietary reward systems, and promotional programs—all designed to boost user engagement.
Long-standing overseas exchanges, operating since around 2011, are recognized for their proven track records and high reliability. These exchanges comply with strict financial regulations in the US, Europe, and other jurisdictions, earning support from both individual and institutional investors.
They provide fiat gateways, allowing direct exchange between crypto assets and multiple major fiat currencies—including the US dollar, euro, British pound, and Japanese yen. Trading fees are relatively low, typically in the 0.01%–0.25% range, and the maker/taker model helps improve market liquidity.
Overseas exchanges offer many advantages not available on domestic platforms. Here, we break down the primary benefits.
One of the biggest advantages of overseas exchanges is the sheer number of tokens available. While domestic exchanges may only support a few dozen tokens, leading overseas platforms offer access to 700–1,000+ cryptocurrencies.
This enables early investment in not only major coins like Bitcoin and Ethereum, but also promising altcoins and tokens from up-and-coming projects. For example, investors can access a wide range of opportunities, including innovative blockchain projects built on Layer 0 protocols and new tokens making waves in the DeFi sector.
Getting in early can be especially attractive for investors aiming for high returns. There have been cases where crypto assets bought in the early stages multiplied in value by tens or even hundreds of times over a few years. However, these opportunities also come with higher risks, so it's essential to thoroughly research the technical foundations and reliability of the development team before investing.
Overseas exchanges go beyond simple buying and selling, offering a comprehensive crypto ecosystem. Key services include:
Liquidity mining lets users deposit crypto assets into exchange-provided pools to earn a share of trading fees as rewards—a compelling way to generate passive income just by holding assets.
**Staking** allows investors to lock up specific crypto assets for a set period, participate in network validation, and earn rewards in return. Some projects offer annual yields of 5%–20%, making this an effective option for long-term holders.
Lending services allow users to earn interest by lending their crypto assets to others. While yields can exceed those of traditional bank deposits, you must also consider borrower default risks.
NFT marketplaces are integrated, supporting the buying and selling of NFTs—such as digital art, game items, and virtual real estate—further broadening investment opportunities.
Another major benefit of overseas exchanges is their low trading fees. Many charge less than 0.1% for spot trades and around 0.02% for futures—significantly lower than domestic exchanges.
Holding the exchange’s native token can unlock further fee discounts, delivering substantial long-term savings for active traders. For users with high monthly trading volumes, VIP programs may offer even more advantageous fee structures.
Fee differences are particularly significant for high-frequency or large-volume traders. Over the course of a year, the cost gap can amount to hundreds of thousands or even millions of yen, making fee structure a critical consideration when choosing an exchange.
If you want to lower the barrier to crypto investing, it’s possible to leverage everyday rewards points or e-money.
Some domestic services let users purchase crypto by linking electronic payment systems. For example, with integrations in messaging apps, users can buy Bitcoin directly within the app, making it easy for beginners to start trading in a familiar interface.
Major flea market apps offering crypto services allow users to buy Bitcoin using sales proceeds or accumulated points. This means you can invest in crypto with funds earned from selling unwanted items—no new capital required.
Services tied to major e-commerce platform point programs let users exchange as few as 100 points for crypto assets. By using points earned from everyday shopping to invest in crypto, you can gain investment experience with lower risk.
These services serve as valuable entry points to crypto for beginners who want to "start small" or "make use of extra funds." However, they often have a limited token selection and higher fees than overseas exchanges, so as your investment grows, it’s wise to consider moving to a dedicated trading platform.
There are several important points you should understand before using overseas exchanges.
One of the most critical rules in crypto investing is to use only surplus funds. The crypto market is far more volatile than stocks or bonds, and it’s not uncommon for asset values to halve in a short period.
Never invest money earmarked for living expenses, emergencies, or near-term obligations. Limit your investments to what you can afford to lose—this is essential for maintaining peace of mind and making rational decisions.
Investing only surplus funds naturally leads to a long-term perspective. This approach lets you focus on a project’s real value and technological progress, rather than short-term price swings, and increases your chances of significant returns. Historical data shows that holding major assets like Bitcoin and Ethereum long-term has produced substantial profits.
As a general guideline, it’s recommended to cap your crypto investments at 5%–10% of your total assets. However, this depends on your individual risk tolerance, experience, age, and income, so make decisions based on your own situation.
Thoroughly understanding the projects you invest in is essential for crypto investing. Evaluate each project from multiple perspectives: technical background, development team track record, project goals, differentiation from competitors, and roadmap feasibility.
Investing in projects you don’t understand is no different from gambling. For instance, blindly following trends in "Layer 0," "DeFi," or "NFT" without grasping their true meaning is extremely risky. Understanding the problems these technologies solve and why they have value is key to identifying a project’s true potential.
When evaluating projects, focus on the following: read the white paper to verify technical feasibility, research the team’s background and achievements for credibility, and check GitHub or similar platforms for code update frequency and development progress.
Community engagement is also a vital indicator. By observing user numbers and discussion quality on Twitter, Discord, Reddit, and other platforms, you can gauge a project’s popularity and support. Partnerships, business alliances, and investor profiles also provide important clues about a project’s credibility.
Proper risk management and security protocols are indispensable when using overseas exchanges. Always enable two-factor authentication (2FA)—preferably with a hardware token or authenticator app. Avoid SMS-based authentication due to the risk of SIM-swap attacks.
Don’t keep large amounts of crypto on exchanges; move long-term holdings to a hardware or other cold wallet for safety. The phrase "Not your keys, not your coins" is a core tenet of crypto security.
Watch out for phishing scams. There are many fake emails and websites impersonating exchanges—always check the URL and access platforms from bookmarks. Avoid trading over public Wi-Fi, and use security measures like VPNs whenever possible.
Diversification is another key element of risk management. Don’t put your entire portfolio in one asset or on one exchange—spread your holdings across multiple tokens and platforms to mitigate risk. The classic investing rule "don’t put all your eggs in one basket" applies just as much to crypto.
The world’s leading crypto exchanges are ranked by trading volume. Major overseas platforms include the top industry names—each with unique features and trading volumes. Because rankings can change frequently, always check for the latest information.
Trading volume reflects liquidity, security ensures funds are safe, and fees represent transaction costs. Prioritize exchanges with high liquidity, strong security credentials, and competitive fee schedules.
Each exchange has its own fee structure and target user base. Some offer low fees but complex interfaces, others are user-friendly but charge higher fees, and some combine competitive fees with robust security.
Legitimate exchanges are licensed by financial regulators and undergo regular security audits. Check for a valid license, strong user reputation, and a transparent fee structure. Always access the official website directly, verify SMS authentication, and confirm the existence of fund protection schemes.
New users must complete identity verification, provide nationality and personal information, residential address, upload both sides of their ID document, and complete facial recognition verification.
Spot trading fees at overseas exchanges usually range from 0.1% to 0.2%. With platform tokens or VIP status, fees can drop to 0.02%–0.08%. Futures trading fees are more complex, including maker/taker fees and funding rates. Fee differences between platforms can be substantial.
Overseas exchanges support trading in 400+ cryptocurrencies, from major coins like Bitcoin and Ethereum to smaller tokens. Top coins enjoy high trading volumes and liquidity, while even lesser-known coins typically maintain solid liquidity.
