Quick answer: To buy crypto in Japan, register with an FSA-licensed exchange such as bitFlyer, Coincheck, or GMO Coin, complete identity verification using your My Number card or residence card, deposit Japanese yen via bank transfer or convenience store, then place your first buy order. Japan regulates crypto tightly, so sticking to licensed platforms keeps your money protected.
Japan holds a unique place in cryptocurrency history. It was one of the first countries to legally recognize Bitcoin as a form of payment, and it built a regulatory framework that many other nations later copied. If you live in Japan—or you’re moving there—buying crypto is straightforward once you understand the rules, the licensed exchanges, and the verification steps involved.
This guide walks you through everything you need to know. You’ll learn which exchanges are officially approved, how to fund your account with yen, how taxes work on your gains, and how to keep your assets secure. By the end, you’ll feel confident placing your first order and avoiding the common mistakes that trip up new investors.
Whether you want to hold Bitcoin for the long term or explore altcoins, the process starts with the same foundation: choosing a trustworthy, regulated platform. Let’s get into it.
Is buying and using cryptocurrency legal in Japan?
Yes, buying and holding cryptocurrency is completely legal in Japan. The country passed the Payment Services Act back in 2017, which officially recognized virtual currencies as a legal method of payment. This made Japan one of the earliest major economies to give crypto a clear legal status.
Regulation falls under the Financial Services Agency (FSA), Japan’s top financial watchdog. Every crypto exchange operating in the country must register with the FSA and follow strict rules on security, customer fund protection, and anti-money-laundering checks. This oversight tightened significantly after the Coincheck hack of 2018, when roughly $530 million in NEM tokens were stolen. Since then, Japanese exchanges have become some of the most secure and closely monitored in the world.
For everyday investors, this heavy regulation is a good thing. It means the platforms you use are held to a high standard, your funds are largely kept in cold storage, and there’s a legal framework protecting you if something goes wrong. The tradeoff is that verification is thorough and some international coins may not be listed. Crypto commentators who follow global markets, like those profiled across independent crypto news outlets, often point to Japan as a model for balancing innovation with consumer safety.
Which crypto exchanges are licensed to operate in Japan?
Only FSA-registered exchanges can legally serve Japanese residents, and this is the single most important detail for new buyers. Using an unlicensed offshore platform puts your money at risk and may create legal and tax headaches down the line. Fortunately, Japan has several well-established, licensed options.
Here are the most popular FSA-approved exchanges:
- bitFlyer — One of Japan’s largest and oldest exchanges, known for high trading volume and strong security. It’s a solid choice if reliability matters most to you.
- Coincheck — Popular for its clean, beginner-friendly app. Despite the 2018 hack, it rebuilt under new ownership (Monex Group) and is now tightly regulated.
- GMO Coin — Backed by the large GMO Internet Group, offering a wide range of coins and useful features for active traders.
- bitbank — Favored by traders who want more advanced charting tools and competitive fees.
- DMM Bitcoin — Known for leveraged trading options, though beginners should approach leverage with caution.
Choose bitFlyer or Coincheck if you’re a beginner who values a simple interface and strong brand trust. Choose bitbank or GMO Coin if lower fees and advanced trading tools matter more to you than a polished app. The rise of Japan’s regulated exchange scene mirrors broader trends covered in founder and startup stories, where compliance-first companies tend to earn lasting customer loyalty.
What documents do you need to open a crypto account in Japan?
To register with any licensed Japanese exchange, you’ll need to complete Know Your Customer (KYC) verification. This is a legal requirement, not an optional step, and it protects both you and the platform from fraud.
You’ll typically need the following:
- A valid ID — Your My Number card (individual number card), residence card (在留カード) for foreign residents, driver’s license, or passport.
- Proof of a Japanese address — Often confirmed through your ID or a utility bill.
- A Japanese bank account — Required to deposit yen and withdraw funds. Most exchanges only work with domestic banks.
- A Japanese phone number — Used for two-factor authentication and account security.
Foreign residents can absolutely open accounts, but you’ll generally need a residence card and a local bank account. Tourists on short-term visas usually cannot register, since exchanges require proof of residency. Verification is often done through eKYC, where you photograph your ID and take a live selfie. Approval can take anywhere from a few minutes to a couple of business days.
How do you buy your first cryptocurrency in Japan, step by step?
Once your account is verified, buying crypto is quick. Here’s the full process from start to finish.
Step 1: Choose and register with a licensed exchange. Pick one of the FSA-approved platforms above, download the app or visit the website, and create your account with your email and a strong password.
Step 2: Complete identity verification. Upload your ID and complete the eKYC selfie process. Wait for approval before moving on.
Step 3: Deposit Japanese yen. Fund your account using one of the available methods—bank transfer, convenience store (konbini) payment, or Pay-easy. Bank transfers are usually the cheapest option.
Step 4: Place your buy order. Navigate to the coin you want, such as Bitcoin or Ethereum, enter the amount in yen you’d like to spend, and confirm the purchase. Beginners should start with a small amount while they learn the platform.
Step 5: Secure your holdings. Enable two-factor authentication and consider moving larger amounts to a private wallet rather than leaving everything on the exchange.
That’s it—you now own cryptocurrency in Japan. Keep records of every transaction, because you’ll need them at tax time.
How does crypto tax work in Japan?
Crypto profits in Japan are taxed as miscellaneous income (雑所得), not as capital gains, and this distinction matters a lot for your bottom line. Miscellaneous income is added to your total annual income and taxed at progressive rates that can climb up to 55% when you include the 45% top national rate and 10% local inhabitant tax.
You owe tax when you sell crypto for yen, trade one coin for another, or use crypto to pay for goods and services. Simply holding crypto without selling does not trigger a tax event. If your annual crypto profit exceeds ¥200,000 and you’re a salaried employee, you’re generally required to file a tax return.
Because rates can be steep, careful record-keeping is essential. Track every buy, sell, and trade along with the yen value at the time. Many investors use crypto tax software or consult a tax accountant (税理士) who understands digital assets. Guides on smart money habits and building wealth, like those shared on personal finance blogs, can help you plan around these obligations before they become stressful.
How can you keep your crypto safe in Japan?
Regulation protects you at the exchange level, but personal security is still your responsibility. The 2018 Coincheck breach is a permanent reminder that even large platforms can be targeted.
Follow these core habits to stay safe:
- Enable two-factor authentication (2FA) on every account, ideally using an authenticator app rather than SMS.
- Use a hardware wallet like a Ledger or Trezor for long-term holdings you don’t plan to trade often.
- Never share your seed phrase with anyone, and store it offline in a secure location.
- Watch out for scams, including fake investment schemes, phishing emails, and social media impersonators promising guaranteed returns.
- Withdraw large balances off the exchange, since coins left on a platform are only as safe as that platform.
Treat your crypto like cash. If someone gains access to your keys, the money is usually gone for good. Digital security best practices, such as those regularly discussed on technology and cybersecurity resources, apply just as much to crypto investors as to any online account holder.
Wrapping up: Your path to buying crypto in Japan
Buying cryptocurrency in Japan is safe, legal, and beginner-friendly—as long as you stick to FSA-licensed exchanges and handle your taxes properly. Start by choosing a trusted platform like bitFlyer or Coincheck, complete your identity verification, deposit yen, and place a small first order to get comfortable with the process.
From there, focus on the fundamentals: keep detailed records for tax season, enable strong security on every account, and move larger holdings into a private wallet. Japan’s tight regulatory environment works in your favor, giving you a level of protection that investors in many other countries simply don’t have.
Take your time, start small, and keep learning. The crypto market moves fast, but a careful, informed approach will always serve you better than chasing hype.
Frequently asked questions
Can foreigners buy crypto in Japan?
Yes. Foreign residents can buy crypto in Japan, but you’ll need a residence card (在留カード), a Japanese bank account, and a local phone number to pass verification. Tourists on short-term visas generally cannot register with Japanese exchanges because proof of residency is required.
What is the minimum amount needed to start buying crypto in Japan?
Most Japanese exchanges let you start with a very small amount, often just a few hundred yen. Coincheck and bitFlyer, for example, allow purchases of Bitcoin for as little as ¥100 to ¥500, making it easy for beginners to test the process without much risk.
Is Bitcoin legal tender in Japan?
No. While Japan legally recognizes Bitcoin as a valid method of payment under the Payment Services Act, it is not official legal tender like the yen. Businesses can choose whether or not to accept it, and many do, but no one is legally required to.
How long does account verification take on Japanese exchanges?
It depends on the platform and method. With eKYC (photographing your ID and taking a selfie), approval can happen within minutes to a few hours. Traditional postal verification can take several business days, so eKYC is the faster choice.
Do I have to pay tax if I only hold crypto without selling?
No. Simply holding cryptocurrency does not trigger a tax event in Japan. Tax applies only when you sell for yen, trade one coin for another, or spend crypto on goods and services. Keep records from day one so you’re ready when a taxable event occurs.
