Why savings rates in Japan finally look interesting
After years near zero, Japan ended negative rates in March 2024 and shifted to a positive-rate regime. Ordinary deposit rates at major banks moved up, with further hikes discussed through 2025. That’s why high-yield savings options are now worth a look. However, Japanese interest rates are still low compared to global standards. If you are moving savings from abroad to deposit in Japan, losing 2-3% in bank exchange fees will wipe out years of interest earnings. Always use Wise to transfer funds at the real exchange rate.
Good to know: Japanese banks quote pre-tax annual rates. Interest on bank deposits is generally withheld at 20.315% at source (national + local taxes including the reconstruction surtax).
What “high-interest” means in Japan right now
In late 2025, competitive ordinary (everyday) savings rates cluster around 0.20%–0.50%, with special programs reaching 0.40%–0.51%. Time-deposit (fixed-term) offers for one year typically sit around 0.275%–0.35%, with longer terms slightly higher. See the bank-by-bank snapshot below for specifics and eligibility.

Snapshot of high-interest ordinary savings (as of Nov 11, 2025)

All rates are pre-tax and variable unless noted by the bank. Banks may change rates without notice; check the bank’s page before applying.
One-year time deposits worth a look
Time deposits (定期預金) can add a little extra yield if you can lock money for months. Sample current offers:
| Bank | 1-year time deposit (indicative) | Notes |
|---|---|---|
| Japan Post Bank | 0.275% | Broad ladder options (up to 10 years). |
| PayPay Bank | 0.275% | Multiple terms; weekly rate reviews. Early redemption uses reduced “mid-term” rates. |
| GMO Aozora Net Bank | Up to 0.31% | Rates vary by term; see bank page. |
| Rakuten Bank | Campaigns vary | Mid-term break penalties can be steep (see their schedule). |
Important: Time deposits are far less flexible. Breaking early usually slashes the effective rate—sometimes to a small fraction of the headline. Keep your emergency buffer in ordinary savings.
Is my money safe? Deposit insurance explained
- Coverage: Yen deposits at insured banks are protected by Japan’s Deposit Insurance Corporation (DICJ) up to ¥10 million principal per depositor per institution, plus interest accrued to the date of failure. Payment & settlement deposits are fully protected.
- Foreign-currency deposits: Not covered by DICJ. If you hold USD/EUR savings, understand both FX risk and lack of insurance.
When accessing your online banking from public Wi-Fi or cafes, security is critical. We recommend using NordVPN to encrypt your connection and keep your financial data safe from hackers.
Taxes on your interest (Japan + US/UK notes)
- Japan: Banks withhold 20.315% on deposit interest automatically; what you see credited is post-tax.
- United States: U.S. persons must report worldwide interest. If your total foreign accounts exceeded $10,000 at any time in the year, you likely need to file an FBAR (FinCEN 114); FATCA Form 8938 may also apply (higher thresholds for those “residing abroad”).
- United Kingdom: UK residents are taxed on worldwide interest; the Personal Savings Allowance may reduce tax, but disclosure rules still apply.
This is general info; please consult a qualified tax adviser for your situation.
Can foreigners open these accounts?
Yes—resident foreigners can generally open savings accounts with a Residence Card, Japanese address/phone, and standard KYC. Also, nearly every bank requires a valid Japanese phone number for verification codes. If you just arrived, Sakura Mobile is the quickest way to get a number without a long-term contract. Some banks offer English support (SBI Shinsei, Sony Bank, SMBC Trust PRESTIA). For overseas transfers in/out, banks commonly require your My Number the first time.
FYI on reporting: Japanese banks must file a report with the tax office when an international remittance is ¥1,000,000 or more under the Act on Submission of Statement of Overseas Wire Transfers—another reason they’ll ask for ID/My Number.

How to choose the right high-yield savings account
- Eligibility & language
If you prefer English interfaces and support, shortlist SBI Shinsei Bank or Sony Bank first, then add a high-yield online bank (Aozora BANK app, GMO Aozora, PayPay Bank) for the “yield pocket.” Money & Finance hub - Rate mechanics
- Flat promotional rate (e.g., Aozora BANK app) is straightforward.
- Linked/bundle rates (Rakuten Money Bridge, au Jibun bundles, PayPay Step-Up) require you to maintain conditions. Review the fine print before moving salary or setting card debits.
- Access & fees
Check ATM access, instant transfers, and app usability. Japan Post Bank’s ATM network is vast; online banks often reimburse some ATM fees. - Safety
Keep emergency cash in yen deposits at insured banks. Foreign-currency savings are not insured by DICJ and add FX risk. - Tax & paperwork
Expect 20.315% withholding on interest; U.S./UK readers, keep your FBAR/FATCA or HMRC reporting in mind. Tax basics for expats in Japan
Simple strategies to boost your yield (without stress)
- Pair accounts: Use a main English speaking bank for daily life and a high-yield online account (Aozora BANK app or GMO Aozora Habito) for your emergency fund.
- Leverage gentle bundles you already use: If you invest with Rakuten Securities, activating Money Bridge is an easy win. au users can stack their existing services at au Jibun Bank.
- Consider time deposits for “future expenses”: If you know you won’t touch funds for 12 months, a 1-year time deposit may add a bit more. Just avoid locking your whole emergency stash and understand early-break penalties. If you don’t need to convert your USD/GBP/EUR to Yen immediately, consider holding them in a Wise Multi-Currency Account. You can avoid FX volatility and convert only when the rates are favorable.
- Watch campaigns: Banks roll out periodic promos. If the headline rate beats your current account by a good margin, shifting your non-urgent cash can pay.
Worked example: building a simple, high-yield setup
Profile: New hire in Tokyo with a Residence Card, paid in yen, wants safety + easy English + decent yield.
- Open SBI Shinsei Bank (English, free transfers at higher stage). Park daily cash here.
- Open Aozora Bank “BANK” app and move your 3–6 months emergency fund to earn 0.50% (first ¥1m).
- If you invest with Rakuten, link Money Bridge for 0.28% on your “buffer” bucket.
- For planned expenses in ~12 months, ladder 1-year time deposits at PayPay Bank or Japan Post Bank.
This mix stays simple, insured (yen deposits), and liquid enough for surprises.
Frequently asked questions
Are these rates fixed?
Ordinary deposit rates are variable. Banks can change them without notice as the Bank of Japan adjusts policy or markets move. Always check the latest bank page before you move money.
Is interest paid monthly or semi-annually?
Most ordinary accounts calculate daily and credit monthly; time deposits generally pay at maturity (or compound periodically), subject to each bank’s terms. See the bank’s interest page for details.
Are foreign-currency savings accounts better?
They can show high stated rates, but FX swings add risk and they are not covered by DICJ insurance. Use them only for money you’re comfortable converting and risking. Keep emergency funds in insured yen deposits.
What documents do I need to open an account?
Typically: Residence Card, proof of address, a Japanese mobile number, and in some cases My Number (especially for overseas transfers).
