If you are a foreign resident in Japan looking to save in your home currency or hold multiple currencies, a foreign currency savings account in Japan could be a smart move. Whether you want to protect savings from yen fluctuations, send money home more efficiently, or simply keep funds in dollars, euros, or another currency, several Japanese banks offer this option — though the features, fees, and eligibility rules vary quite a bit. This guide walks you through what to look for, which banks are worth considering, and how to get started.
What Is a Foreign Currency Savings Account?
A foreign currency savings account (外貨預金, gaika yokin) lets you deposit and hold money in a currency other than Japanese yen — such as US dollars, euros, Australian dollars, or British pounds. Interest rates on these accounts are sometimes higher than on standard yen savings accounts, which can be attractive. However, exchange rate fluctuations mean the value of your savings in yen terms can go up or down, so it is important to understand the risks before opening one.
Key things to be aware of:
- Foreign currency deposits are not covered by Japan's deposit insurance (the Deposit Insurance Corporation scheme that protects yen deposits up to ¥10 million). This is a significant risk to understand.
- Exchange rates and spreads (the gap between buying and selling rates) differ by bank and can eat into your returns.
- Interest rates vary by currency and by bank, and change frequently — always check the current rate on the bank's official site.
Which Japanese Banks Offer Foreign Currency Savings Accounts for Foreigners?
Several banks in Japan — both traditional and online — offer foreign currency savings accounts. Here is a practical overview. Because fees, rates, and eligibility rules change regularly, treat this as a general guide and confirm the latest details directly with each bank.

What to Compare When Choosing a Foreign Currency Account
Not all foreign currency accounts are equal. Here are the key things to look at side by side:
- Exchange rate spread: This is the difference between the rate you get when buying a foreign currency and when selling it. A narrower spread saves you money. Online banks like Sony Bank are often praised for tighter spreads than traditional megabanks.
- Interest rates: These vary by currency and change frequently. Check the current rate on the official site — do not rely on rates quoted in articles like this one.
- Transfer and conversion fees: Some banks charge a flat fee per transaction; others build costs into the exchange rate. Read the fee schedule carefully.
- Minimum deposit: Some accounts require a minimum opening deposit. Confirm before applying.
- Residency requirements: Many traditional banks ask that you have lived in Japan for around six months before opening any account. Online banks are sometimes more flexible, but rules differ.
- English support: If your Japanese is limited, look for banks with English-language websites, apps, or customer service.
- Application method: Online banks let you apply from home; traditional banks usually require a branch visit.
Documents You Will Typically Need
Requirements vary by bank, but as a foreign resident in Japan you will generally need:
- Your residence card (在留カード, zairyu card) — your most important ID document
- Proof of your Japanese address (your residence card usually shows this)
- A Japanese phone number (required by most banks for verification)
- Sometimes a personal seal (hanko) — less common for online banks, but some traditional banks still ask
- Your My Number (個人番号) — Japan's individual identification number, required for most financial accounts
Always check the specific bank's requirements before visiting a branch or starting an online application, as these can differ.
What If You Cannot Open a Bank Account Yet?
If you have just arrived in Japan and have not yet met the residency requirements of traditional banks, you are not without options. Wise (formerly TransferWise) is a licensed e-money service — not a bank — that lets you hold, receive, and convert multiple currencies using your own account details. It is a practical interim solution for managing money across currencies while you wait to become eligible for a Japanese bank account. Keep in mind that Wise is not a deposit account and has its own fee structure, so compare it with your needs.
Things to Watch Out For
- Exchange rate risk: The yen value of your foreign currency savings can fall if exchange rates move against you. Only hold foreign currency you can afford to leave untouched for a while.
- No deposit insurance: Unlike yen deposits, foreign currency deposits in Japan are not protected by deposit insurance. This is a real risk — make sure you are comfortable with it.
- Hidden costs: Some banks advertise attractive interest rates but offset this with wide exchange spreads. Look at the total cost, not just the headline rate.
Summary: Choosing the Right Foreign Currency Savings Account in Japan
Opening a foreign currency savings account in Japan as a foreigner is absolutely possible, and it can be a genuinely useful tool — whether you want to save in your home currency, reduce the cost of sending money abroad, or take advantage of higher interest rates on certain currencies. Online banks like Sony Bank and SBI Shinsei Bank tend to offer competitive spreads and more flexible application processes, making them a good starting point for foreign residents. Traditional megabanks like MUFG and SMBC have broader branch networks but may require a longer residence history and involve more paperwork.
Before opening any account, compare exchange rate spreads, fees, interest rates, and English support carefully — and always confirm the latest terms on the bank's official website, as these details change regularly. Remember that foreign currency deposits carry risks that yen deposits do not, so make sure you understand those before committing your savings.
If you are still in the early days of life in Japan, take it one step at a time. Start by getting a basic yen account (Japan Post Bank is often accessible to new arrivals), build your financial foundation, and then explore foreign currency options as your situation settles. You have more choices than you might think — and the right account is out there for you.
