How Do Japan’s Deposit Rates Really Compare?

How Do Japan’s Deposit Rates Really Compare?

The Bank of Japan raised its policy rate to 1.0% in June 2026 — a genuinely notable shift after years of near-zero rates. If you’re a foreign resident deciding where to park your yen savings, here’s what the landscape actually looks like now.

Megabanks vs Online Banks

Comparison of Japanese bank deposit rates in 2026

Japan’s major megabanks — MUFG, Mizuho, SMBC — remain convenient for everyday banking but are rarely where you’ll find the best deposit rates. Online banks have consistently offered more competitive terms:

  • Aozora Bank BANK: ordinary savings rate raised to an industry-leading 1.00% from July 1, 2026; a special new-account time deposit offer reaching 1.60%
  • Sony Bank: standard time deposit rates aren’t exceptional, but its installment-style time deposit tends to be relatively competitive
  • Rakuten Bank: occasionally runs promotional rates tied to its affiliated sports teams’ performance — a quirky but real feature of its offering

How Interest Income Is Taxed

Interest on deposits in Japan is subject to a flat 20.315% withholding tax (15% national income tax, 0.315% special reconstruction tax, and 5% resident tax). This is deducted automatically at the source — you generally don’t need to file anything separately for ordinary deposit interest.

Should You Compare Against Your Home Country’s Rates?

If you still hold savings or accounts back home, it’s worth comparing rates — many countries’ deposit products currently offer higher nominal yields than Japan’s. But before moving money based on rate alone, weigh in currency risk: converting yen into another currency to chase a better rate exposes you to exchange rate swings that can easily outweigh the rate difference over the holding period, especially for short time horizons.

A more practical approach is usually to think about currency by purpose — keep savings you’ll spend in Japan in yen, and only consider converting funds you genuinely don’t need in the near term, with the FX risk clearly in mind.
