Managing Your Finances as an Expat in Japan
Japan uses the Japanese yen ( ¥). The exchange rate has been roughly ¥140–¥160 per dollar in recent years — historically weak, making Japan more affordable for USD earners. Japanese banking is reliable but traditional. Opening an account requires a residence card (zairyu card). Most expats use a combination of a Japanese bank, Wise, and their home-country accounts.

Cash vs. card culture
Japan is modernizing payments rapidly (PayPay, IC cards like Suica/Pasmo), but cash remains important. Many restaurants, especially smaller ones, are cash-only. Vending machines often take IC cards. Always carry ¥10,000–¥20,000 in cash.
Cost of Living in Japan
| Category | Typical Cost |
|---|---|
| Rent | ¥70,000–¥150,000/month ($470–$1,000 USD) in Tokyo |
| Groceries | ¥30,000–¥50,000/month ($200–$335 USD) |
| Transport | ¥10,000–¥20,000/month ($67–$135 USD) for a commuter pass |
| Healthcare | National health insurance: ~¥20,000/month ($135 USD), covers 70% of costs |
Tokyo is comparable to mid-tier US cities. Smaller cities are significantly cheaper. The weak yen makes Japan more affordable for dollar-earners than it has been in decades.

Currency Considerations
USD/JPY has been one of the most volatile major pairs in recent years, ranging from ¥130 to ¥160+. The weak yen benefits dollar-earners significantly, but budgeting at the current rate without a buffer is risky if the yen strengthens.
Transferring money to Japan
- Wise supports USD→JPY transfers with competitive rates. Japanese banks charge ¥2,500–¥4,000 for incoming international wires.
- Sony Bank is the most foreigner-friendly Japanese bank for multi-currency accounts.
- The yen has weakened significantly against the dollar in recent years. Your USD goes further, but this can reverse.
- 7-Eleven and Japan Post ATMs accept most international cards. Convenience store ATMs are your friend.
Borderless Budget tracks all of your accounts, your home-country bank, your Japan bank, and services like Wise or Revolut , in a single dashboard. Exchange rates update daily from central bank sources, so your budget always reflects where things actually stand.
Tax Considerations for Expats in Japan
- Japan taxes residents on worldwide income. The US-Japan tax treaty helps avoid double taxation.
- Japanese income tax is progressive, plus local inhabitant tax (~10%). Combined rates can reach 55% at the top bracket.
- If you’re on a working visa, your employer handles tax withholding. Year-end adjustment (nenmatsu chōsei) is like a mini tax return.
- Report foreign financial accounts to the NTA if your total overseas assets exceed ¥50 million.
Budgeting Tips for Expats in Japan
- Budget in yen. The numbers are large (rent of ¥100,000 is ~$670) but that’s the currency you spend in daily.
- Japan is more cash-dependent than you’d expect for a country this advanced. Many small restaurants and shops are cash-only.
- Convenience store spending adds up. ¥500–¥1,000/day at 7-Eleven or Lawson is easy to burn through. Set a limit.
- Japanese healthcare covers 70% of costs. Budget ¥5,000–¥10,000/month for the 30% co-pay on doctor visits and prescriptions.
- The weak yen is a tailwind for USD-earners right now. But don’t get complacent — build your budget around a conservative rate.
- Seasonal costs vary. Summer means high air conditioning costs; winter means heating. Budget ¥5,000–¥15,000 extra for peak seasons.
