Introduction
Moving to Japan is one of the more rewarding relocations an American can make — safe, orderly, endlessly interesting — but it is also more administrative than a working holiday elsewhere. Your visa, your ongoing US tax filings, the upfront cost of renting, and the mechanics of insurance and banking all need handling, mostly in that order.
None of it is insurmountable with preparation. What follows is an overview of the moving parts. Because rules change and everyone’s circumstances differ, treat this as a starting map and verify the specifics with immigration and tax professionals.
Securing the Right Visa
Everything starts with the correct status of residence, arranged before you move.
Work Visas and Sponsorship
The most common route is a work visa sponsored by a Japanese employer, in categories such as Engineer/Specialist in Humanities/International Services, or the Instructor category for teaching. You generally need a job offer first; the employer helps obtain a Certificate of Eligibility, which you convert to a visa at a consulate. No job, no sponsorship, so the job search usually comes first.
The Highly Skilled Professional Visa
Japan’s Highly Skilled Professional visa uses a points system rewarding education, income, and experience, and offers real perks — longer stays and a faster track toward permanent residency. If your qualifications and salary are strong, it is worth investigating, as it can significantly shorten the road to settling permanently.
Digital Nomad and Spouse Visas
Other paths exist depending on your situation: Japan’s remote-work (digital nomad) route for qualifying overseas earners, and a spouse visa if you are married to a Japanese national or eligible resident. Each has its own conditions, so match the visa to your actual circumstances rather than assuming one fits.
US Expat Taxes in Japan
This is the part Americans most often underestimate. The US taxes based on citizenship, so moving abroad does not end your US filing obligations.
You Still File with the IRS
As a US citizen, you must continue filing an annual federal tax return no matter where you live, reporting worldwide income. Living in Japan does not exempt you. This surprises many first-time expats, so build it into your plans from day one.
FEIE vs. Foreign Tax Credit
To avoid being taxed twice on the same income, two main tools exist: the Foreign Earned Income Exclusion (FEIE), which excludes a large band of foreign earned income, and the Foreign Tax Credit (FTC), which credits taxes you paid to Japan against your US bill. Which is better depends on your income and situation — a cross-border tax professional is worth the fee here.
FBAR and FATCA
Beyond the return, you likely must file an FBAR (Report of Foreign Bank and Financial Accounts) if your Japanese accounts exceed the reporting threshold, and FATCA rules may require additional reporting. These are disclosure requirements, separate from tax owed, and the penalties for missing them are steep, so do not overlook them.
Finding an Apartment
The Upfront Costs
Japan’s rental system front-loads costs in a way that shocks newcomers. Beyond the deposit (shikikin), many leases charge non-refundable “key money” (reikin) as a gift to the landlord, plus an agency fee and the first month’s rent. Budget several months’ rent in cash just to move in.
Guarantor Companies
Most rentals require a guarantor, and since few newcomers have a Japanese one, you use a guarantor company (hoshо̄ gaisha) for a fee — they underwrite your lease. This is a normal, expected part of renting; factor its cost into your move-in budget.
Foreigner-Friendly Agencies
Some landlords are hesitant to rent to non-Japanese speakers, so English-friendly real estate agencies and platforms in Tokyo, Osaka, and other cities exist specifically to bridge that gap. Starting with one of these saves considerable friction on your first lease.
Setting Up Daily Life
National Health Insurance
Residents enroll in Japan’s health system — National Health Insurance for many, or employer-based insurance through a company — which typically covers around 70% of medical costs, leaving you to pay about 30%. Coverage is broad and care is excellent and affordable by US standards. Enrolling at your local ward office is one of your first tasks after arrival.
Opening a Bank Account
Opening a Japanese bank account can require a residence card and, at some banks, a few months of residency or a local phone number before they will open certain account types. Requirements vary by bank, so ask about foreigner-friendly options; some are more accommodating to new arrivals than others.
Getting a Phone
For connectivity, budget SIM cards and eSIMs are available, and some do not require a Japanese credit card, which helps before your banking is set up. A local number smooths many other setups — banking, rentals, deliveries — so sort a phone early.
Expert Tip
Arrive with more cash reserves than you think you need. Between key money, deposit, agency and guarantor fees, and first month’s rent, moving into an apartment alone can cost the equivalent of four to six months’ rent upfront — before furniture, deposits for utilities, or a single paycheck lands. First salaries can also be a month or more away. A healthy cash cushion is the difference between a smooth landing and a stressful one.
Cost of Living and Adapting
US vs. Japan Costs
The trade-offs are real: healthcare and public transit are far cheaper than in the US, and eating out can be excellent value, while housing space is smaller and some imported goods cost more. Overall, many Americans find daily living costs comparable or lower, with a very different distribution of where the money goes.
The Language Barrier
You can get by in the biggest cities with limited Japanese, but official life — ward office paperwork, contracts, medical forms — leans heavily Japanese. Learning basic conversational and practical Japanese pays off quickly and is essential for settling in beyond the tourist bubble.
Community Norms
Adapting to local norms matters more in an apartment building than on a trip: quiet hours, meticulous trash sorting on specific days, and neighborhood courtesies are taken seriously. Learning and following these unwritten rules early earns goodwill and avoids friction with neighbors.
Moving to Japan from the US: Frequently Asked Questions
Can I move to Japan without a job offer first? For a standard work visa, you generally need a job offer and employer sponsorship before you can obtain the status. Some other routes (such as certain remote-work or spouse categories) do not require a local job, so it depends on which visa fits your situation.
Do Japanese banks report my accounts to the IRS? Under FATCA, financial institutions in Japan may report US persons’ account information, and you are separately responsible for your own FBAR and FATCA filings. Assume your foreign accounts must be disclosed and file accordingly.
How much cash should I prepare before arriving? Enough to cover several months of living costs plus the heavy apartment move-in fees (often four to six months’ rent upfront) and expenses before your first paycheck. Err generously; the upfront costs are larger than most newcomers expect.

Conclusion
Moving to Japan from the US is very achievable, but it rewards preparation over improvisation: line up the right visa, plan for ongoing US tax filings, budget for the steep cost of renting, and sort insurance and banking early. The administrative side is the hard part; daily life, once you land, is one of the great pleasures of living here.
