1 Moving your money (USD → JPY)
USD→JPY is a deep, highly liquid major corridor; specialist FX providers generally beat a US bank wire's rate, and for tax residents, large inbound remittances raise the non-permanent-resident remittance question, so time them with that in mind.

The visible fee isn't the cost; the exchange-rate spread is. A specialist like Wise typically beats a bank wire on USD→JPY; compare your exact amount first.

2 Banking as an American in Japan
In practice you need a residence card (zairyu card) from a mid/long-term visa, a registered Japanese address, and usually a My Number; a Japanese phone number is typically required too. Major banks (MUFG, SMBC, Mizuho) and Japan Post Bank are common, but newcomers are often told to wait ~6 months after arrival for a normal account, and Japanese-language paperwork is the norm. As a US person you'll complete FATCA self-certification.
Local banks generally accept US persons under the FATCA agreement, though some are cautious about the extra reporting.
3 Taxes: the part everyone gets wrong
The US side: you still file
- FEIE / FTCYou file a US return on worldwide income. FEIE or the Foreign Tax Credit usually prevents true double taxation; which one wins depends on your income and local rates.
- $10,000FBAR (FinCEN 114) if your foreign accounts top $10,000 combined at any point in the year.
- Form 8938FATCA reporting may also apply above higher thresholds.
The Japan side
Japan offers a special regime, Non-permanent resident rule. Japan has NO inbound expat tax incentive, but a non-Japanese-national 'non-permanent resident' (someone with a Japanese residence who has NOT had a domicile/residence in Japan for more than 5 of the last 10 years) is generally taxed only on Japan-source income PLUS foreign income paid in or remitted to Japan; foreign-source income kept abroad is not taxed. After more than 5 years of residence you become taxable on worldwide income. (Since 1 Apr 2017, gains on securities acquired and sold while an NPR can be taxed even without remittance.) Japan also has an exit tax (flat 15.315% on deemed unrealized gains) on departing residents holding ¥100M+ in covered financial assets who lived in Japan more than 5 of the prior 10 years. Verify current rules.
Where this gets people
- The non-permanent-resident remittance trap: foreign-source income you bring into or remit to Japan becomes taxable there (combined national+local can near ~55%); keeping money abroad keeps it out of the Japanese net, but the US still taxes it all.
- Japanese mutual funds and ETFs are PFICs to the IRS (punitive tax + a Form 8621 per fund), so favor US-domiciled investments.
- Long-term residents (5+ of the last 10 years) holding ¥100M+ in financial assets face a Japanese exit tax on unrealized gains when they leave.
- You generally can't open a local bank account until residency is sorted. Arrange a transfer/multi-currency account for the gap.
- A "special regime" headline rate is not your effective rate: eligibility and exclusions matter a lot.
- State taxes can follow you abroad depending on the US state you left, so don't assume you're done with them.

4 Investing & brokerage
US brokers sometimes drop customers with a non-US address. A broker that explicitly supports non-resident Americans is the standard fallback. Beware buying local (non-US) funds: PFIC (Passive Foreign Investment Company) rules make them a US tax nightmare.

Interactive Brokers
Interactive Brokers explicitly supports non-resident Americans, so a Japan address won't get your account closed, and US-domiciled funds keep you clear of PFIC.

Legal residents generally gain access to Japan's public health system, but there's usually a gap before residency and coverage kick in. Many new arrivals and nomads bridge the gap with international coverage.

Frequently asked questions
Do Americans living in Japan still have to file US taxes?
Yes. US citizens file with the IRS on worldwide income no matter where they live. The US-Japan tax treaty and tools like the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit usually prevent true double taxation, but you still must file. This is general information, not tax advice.
Do I need to file an FBAR if I move to Japan?
If your foreign financial accounts add up to more than $10,000 at any point in the year, you generally must file an FBAR (FinCEN Form 114). Many expats also have FATCA (Form 8938) obligations. Penalties for missing these are steep, so confirm your situation with a cross-border professional.
What's the cheapest way to move money to Japan?
For a relocation lump sum, the cost is almost entirely the exchange-rate spread, not the visible fee. Banks commonly bury 1-3% in the rate. Compare your specific amount with the transfer cost tool before sending.
Can I keep my US brokerage account after moving to Japan?
Some US brokers restrict or close accounts once you have a non-US address. A broker that explicitly supports non-resident Americans is the common fallback. Don't change your address until you've confirmed your broker's policy.
What is the Non-permanent resident rule regime in Japan?
Japan has NO inbound expat tax incentive, but a non-Japanese-national 'non-permanent resident' (someone with a Japanese residence who has NOT had a domicile/residence in Japan for more than 5 of the last 10 years) is generally taxed only on Japan-source income PLUS foreign income paid in or remitted to Japan; foreign-source income kept abroad is not taxed. After more than 5 years of residence you become taxable on worldwide income. (Since 1 Apr 2017, gains on securities acquired and sold while an NPR can be taxed even without remittance.) Japan also has an exit tax (flat 15.315% on deemed unrealized gains) on departing residents holding ¥100M+ in covered financial assets who lived in Japan more than 5 of the prior 10 years. Verify current rules. Eligibility and exclusions matter: a regime's headline rate is not your effective rate, so confirm against current law before relying on it.
Can I open a local bank account in Japan as an American?
Usually not until residency is sorted. Once resident, banks generally accept US persons under the FATCA agreement. Most arrivals bridge the gap with a multi-currency account opened before the move.
