👉 Discover how easy it is to begin your crypto journey today.
What Is Cryptocurrency?
Cryptocurrency, also known as digital or virtual currency, refers to digital assets with financial value that can be used online for transactions. The most well-known example is Bitcoin, but thousands of other cryptocurrencies exist.
Unlike traditional money issued by governments (like the Japanese yen or U.S. dollar), cryptocurrencies operate on decentralized networks using blockchain technology—a secure, transparent ledger system that records all transactions across a network of computers.
Legal Definition of Cryptocurrency
Under Japan’s Payment Services Act, cryptocurrency is defined by three key characteristics:
- It can be used as payment by unspecified parties.
- It can be exchanged freely with legal tender (e.g., yen, dollars).
- It is stored and transferred electronically and is not itself a fiat currency or prepaid instrument.
This means cryptocurrency functions as a borderless, digital form of value—revolutionizing how we think about money and financial transactions.
Types of Cryptocurrencies
While Bitcoin (BTC) remains the original and most dominant digital asset, all other cryptocurrencies are collectively called altcoins. Popular examples include Ethereum (ETH), Ripple (XRP), and Litecoin (LTC). Each has unique features and use cases, such as smart contracts (Ethereum) or faster cross-border payments (Ripple).
In Japan, regulated exchanges offer around 13–16 major cryptocurrencies, ensuring safety and compliance through oversight by financial authorities like the Financial Services Agency (FSA).
How to Profit from Cryptocurrency Investing
One of the main reasons people turn to crypto is its potential for high returns. However, profits come with risks due to price volatility. Here are two common ways investors generate returns:
1. Capital Gains Through Trading
The most straightforward method is buying low and selling high. Due to significant price swings, some cryptocurrencies have seen gains of 10x or even 100x in short periods. For example, early Bitcoin investors witnessed explosive growth over the past decade.
However, prices can also drop sharply—so timing and research matter.
2. Earning Passive Income via Staking
Similar to earning interest on a savings account, staking allows you to earn rewards just by holding certain cryptocurrencies. By participating in network validation (like verifying transactions on a blockchain), users receive additional tokens as incentives.
Coins like Ethereum support staking, offering annual yields that vary based on network conditions—making it an attractive option for long-term holders.

Step-by-Step Guide to Starting with Cryptocurrency
Starting your crypto journey is easier than you think. Follow these four essential steps:
Step 1: Prepare Required Identification Documents
To open an account with a regulated exchange in Japan, you’ll need valid ID. Acceptable documents typically include:
- Driver’s license
- My Number card
- Health insurance card
- Passport
Make sure your documents are up-to-date and clearly legible when uploading.
Step 2: Open an Account at a Cryptocurrency Exchange
Visit the official website of your chosen exchange and complete the registration form. You’ll provide personal details like name, address, and phone number, then upload your ID for verification.
Account approval may take several hours to a few days—so apply early if you're eager to start trading.
Step 3: Deposit Japanese Yen into Your Account
Once verified, transfer JPY from your bank account to your crypto exchange wallet. Some platforms also allow cash deposits via convenience stores.
Many exchanges let you keep JPY in your account without converting it—giving you flexibility to buy crypto when prices are favorable.
💡 Tip: Start small. Begin with as little as ¥500–¥1,000 to get comfortable with the platform before investing larger amounts.
Step 4: Start Buying Cryptocurrency
After funding your account, select the cryptocurrency you'd like to purchase and exchange yen for digital assets. Be aware of spreads—the difference between buy and sell prices—as wider spreads increase trading costs.
Most platforms offer intuitive interfaces with real-time charts and one-click buying options—perfect for beginners.

Pros and Cons of Cryptocurrency Investment
Before diving in, understand the advantages and risks involved.
✅ Advantages
1. 24/7 Market Access
Unlike stocks or forex markets that close on weekends, crypto trades 24 hours a day, 365 days a year. With mobile apps, you can monitor prices and execute trades anytime—from anywhere.
2. Global Usability
Cryptocurrencies are borderless. They can be used internationally without exchange fees or delays—making them ideal for global transactions or travel spending.
❌ Risks and Drawbacks
1. High Price Volatility
Prices can swing dramatically within hours. While this creates profit opportunities, it also increases the risk of losing capital quickly.
⚠️ Never invest money needed for daily expenses or long-term goals like retirement or education.
2. Tax Implications
In Japan, crypto profits are classified as miscellaneous income and subject to comprehensive taxation (15%–55%), depending on total annual income.
This differs from stocks or FX, which are taxed at a flat ~20% rate under separate reporting rules.
Key Tips Before You Start Investing
To trade safely and wisely, keep these points in mind:
Use Only Surplus Funds
Treat cryptocurrency as a high-risk investment. Only use money you can afford to lose after covering essentials like rent, food, and emergency savings.
Educate Yourself First
Don’t jump in because “everyone’s doing it.” Learn the basics of blockchain, understand major coins like Bitcoin and Ethereum, and follow market news regularly.
👉 Access free tools and insights to stay ahead in the crypto market.
Consider Multiple Exchange Accounts
Opening accounts across different platforms gives you access to more coins and trading options. It also helps diversify risk—if one exchange faces downtime or issues, you’re not locked out entirely.
Protect Against Hacks and Theft
Despite strong security measures, hacking incidents have occurred in the past. Always enable two-factor authentication (2FA) and consider using hardware wallets for large holdings.
Remember: Your keys, your coins. Not your keys, not your coins.
