How to Buy Bitcoin for Beginners in Japan: From Opening an Account to Storage [2026]

To buy Bitcoin, the most common approach is to open an account with a crypto-asset exchange registered with Japan's Financial Services Agency (FSA), deposit Japanese yen, and then make your purchase. This article neutrally outlines the three basic steps, along with considerations for storage and risk.

Things to Know Before You Buy

Bitcoin's price can swing sharply, and its value can rise or fall dramatically in a short period. Your purchase amount could fall below what you invested, so it's important to consider buying only with funds you can afford to lose without disrupting your daily life.

Explanatory articles you'll find through a search generally describe a three-step process as the basics: open an account with a domestically registered provider, deposit funds, and then make your purchase. However, whether trading is permitted and how it's taxed varies by country and region. In Japan, the safest approach for understanding how profits are treated is to check with a tax professional or the National Tax Agency.

Three Basic Steps

1. Open an Account

Fill in the required information on your smartphone or computer and submit identity verification documents. Review can take several days, so allow plenty of time. Exchanges differ in the documents and procedures they accept, so check the official website in advance.

2. Deposit Japanese Yen

Deposit Japanese yen into your exchange account, for example by bank transfer. Deposit methods and transfer fees vary by exchange, so check each company's official page for the latest terms.

3. Buy Bitcoin

There are two main ways to buy: the "dealer" format, where the exchange itself is your counterparty, and the "exchange" format, where users trade directly with each other. Dealer-style trading is generally considered simpler to use, but the effective price spread tends to be wider. Beginners are advised to understand how the system works and how prices are displayed before placing an order. Some services allow you to start with small amounts, but choose the amount based on your own financial situation.

Storing Your Bitcoin After Purchase

After you buy Bitcoin, you can either leave it in your exchange account or move it to a personal wallet. Keeping it on an exchange is convenient, but your funds may be affected by unauthorized access to the exchange or by system failures. Moving it to a wallet means you are responsible for managing it yourself, and if you lose your private key or recovery phrase, you will not be able to recover your funds.

Things to Keep in Mind Before You Start

• Watch out for scams and impersonation, and only use official websites and official apps
• Set up two-factor authentication and do not reuse passwords
• Do not respond to solicitations that promise "guaranteed profits" or "principal protection"
• Understand the risk of losses if prices suddenly drop, and start with a small amount
