Living in Japan as a U.S. citizen means securing a long-term residence visa tied to a specific reason for staying — a job, marriage to a Japanese national, school enrollment, remote work, or running a business — then handling a sequence of registrations after you arrive and filing taxes in both countries every year. The 90-day visa-free window Americans get on arrival is for visiting, not settling, and you cannot convert it into a long-term visa from inside the country. Everything else, from health insurance to your U.S. tax return, follows from getting the visa piece right first.
The 90-Day Visa-Free Window Is Not a Path to Residency
U.S. passport holders can enter Japan for up to 90 days without a visa for tourism or business meetings.1U.S. Department of State. Japan Travel Advisory During that window you cannot work, enroll in school, or switch to a long-term visa from inside the country. Immigration officers can also deny entry if you can’t show how you’ll support yourself.
The visa-free entry is useful for scouting neighborhoods, sitting for interviews, or visiting a school in person before you commit. But any paid work, including remote freelancing for a Japanese client, requires proper authorization. If you want to live in Japan, you apply for the correct visa from the United States and enter with it in hand. Skipping that step usually means flying home to start over.
Choosing the Right Long-Term Visa
Japan issues residence visas by category, and the category has to match what you’ll actually be doing. Each has its own paperwork, sponsor requirements, and length of stay.
Work Visa
The most common route for Americans is a work visa built on a signed employment contract with a Japanese employer. The subcategory depends on the field. “Engineer/Specialist in Humanities/International Services” covers most white-collar roles in IT, finance, marketing, and language instruction, and separate categories exist for researchers, artists, entertainers, and skilled tradespeople. Work visas are typically granted for one, three, or five years and can be renewed.
Spouse of a Japanese National
If you marry a Japanese citizen, the spouse visa lets you live and work in Japan without restrictions on the type of employment. You’ll need your marriage certificate and your spouse’s family register (koseki tohon).2Ministry of Foreign Affairs of Japan. Specified Visa – Spouse or Child of Japanese National Immigration looks closely at whether the marriage is genuine, so expect documentation questions about your relationship history.
Student Visa
A student visa requires acceptance from a recognized Japanese educational institution, which acts as your sponsor, plus proof you can cover tuition and living expenses. A common benchmark is around ¥2,000,000 (roughly $13,000 to $14,000) in annual income and savings, though the exact standard depends on your school and location. Student visa holders can work up to 28 hours per week after getting a separate work permission from immigration.
Highly Skilled Professional Visa
Japan’s points-based Highly Skilled Professional visa rewards applicants with strong academic credentials, professional experience, and higher salaries. You earn points across education, career history, age, and annual income. Scoring 70 points qualifies you and comes with a five-year residence period, permission for your spouse to work, and a faster track to permanent residency. Hitting 80 points can qualify you for permanent residence in as little as one year.
Digital Nomad Visa
Japan’s Digital Nomad visa is for remote workers employed by companies outside Japan. The stay is capped at six months with no option to extend, and you must earn at least ¥10 million per year (approximately $68,000).3Ministry of Foreign Affairs of Japan. Specified Visa – Designated Activities (Digital Nomad) You’ll need income documentation such as tax certificates or an employment contract showing the amount. Spouses and children can accompany you on dependent visas.
Business Manager Visa
If you plan to start or manage a business in Japan, the Business Manager visa requires establishing a company with a physical office and meeting capital investment and staffing thresholds. Japan recently revised these requirements, raising the minimum investment significantly and adding a requirement to employ Japanese nationals or permanent residents. Because the specifics have changed, check with the Immigration Services Agency of Japan or a qualified immigration attorney for current figures before committing capital.
The Certificate of Eligibility
For most long-term visas, you need a Certificate of Eligibility (COE) before you can apply for the visa itself. The COE is not a visa. It’s a document from Japan’s Immigration Services Agency confirming your planned activities qualify you for the category you’re seeking, and having one dramatically speeds up the visa application at the embassy or consulate.4Embassy of Japan in the United States of America. Visa (COE Holders) – Section: What is Certificate of Eligibility (COE)?
Your sponsor in Japan (your employer, school, or Japanese spouse) files the COE application at their local immigration office.5Consulate-General of Japan in Miami. Applying for Visa with Certificate of Eligibility (COE) Processing commonly takes one to three months, so build that wait into your timeline. Once you have the COE, you take it with your passport, a completed visa application form, and a recent passport-sized photo to a Japanese embassy or consulate in the U.S. to apply for the visa itself.6Embassy of Japan in the United States of America. Visa (Short-Term Visit) Application forms are downloadable from the embassy and consulate websites.7Consulate-General of Japan in Seattle. Visa Application Forms
Criminal Record Bars You Should Check Before You Apply
Japan has some of the strictest entry rules in the world for people with criminal histories. Under the Immigration Control and Refugee Recognition Act, several categories can result in outright denial of entry:
- Any conviction related to narcotics, marijuana, stimulants, or psychotropic substances, regardless of sentence length, including simple possession.8Embassy of Japan in New Zealand. Criminal Record and Entry Into Japan
- A conviction in any country that resulted in a prison sentence of one year or more, with a narrow exception for political offenses.
- Convictions related to human trafficking, prostitution, or illegal weapons possession.
The final call happens at the immigration counter on arrival. If you have concerns about your record, contact the Immigration Services Agency of Japan before you book travel.9Consulate-General of Japan in Seattle. Traveling to Japan Quick Facts – Section: Travelers With Criminal Records and Refusal of Entry There is no formal pre-clearance process; you are asking for guidance, not a guarantee.
What to Do in Your First Two Weeks
The first two weeks after landing are front-loaded with paperwork. Getting through it promptly avoids fines and unlocks everything else, from a bank account to a lease.
Residence Registration
When you arrive at the airport on a long-term visa, you’ll receive a residence card (zairyu card). Within 14 days of settling into your address, you must register that address at your local ward or city office. Bring your passport and residence card. Failing to register within the deadline can result in a fine of up to ¥200,000, and ignoring the requirement for 90 days without a valid reason can lead to revocation of your residence status.
My Number Card
A few weeks after registering your address, you’ll receive a letter containing your 12-digit My Number and an application form for the My Number Card. The card is your primary ID in Japan and doubles as your health insurance card. You can use it to pull official documents at convenience stores, file taxes online, and handle government procedures without visiting a municipal office. Apply online, by mail, or at a photo booth using the QR code on the form, then pick up the finished card at your ward office about a month later.
Opening a Bank Account
A Japanese bank account is effectively required for daily life. Employers deposit salary into one, and landlords expect rent by automatic bank transfer. Most major banks want your residence card, passport, a Japanese phone number, and proof of address. Some banks impose a waiting period of several months after arrival before letting you open an account, though this varies by institution. Getting a Japanese phone number first, even a prepaid SIM, makes the process much smoother.
Health Insurance and National Pension
National Health Insurance
Every foreign resident staying more than three months must enroll in Japan’s health insurance system, regardless of any private U.S. coverage you carry.10National Agriculture and Food Research Organization. National Health Insurance If your employer provides company-sponsored health insurance (shakai hoken), enrollment happens through them automatically. Everyone else — self-employed workers, students, freelancers — enrolls in National Health Insurance (NHI) at the ward office.
NHI covers about 70% of eligible medical costs, and you pay the remaining 30% at the point of care. Monthly premiums are based on your prior year’s income, so first-year premiums may be relatively low. Present your insurance card, or your My Number Card, at the reception counter to receive covered care.
One exception: the U.S.–Japan Totalization Agreement lets workers temporarily transferred to Japan by a U.S. employer, for up to five years, stay on U.S. Social Security and potentially skip Japanese social security contributions entirely, including the health insurance portion, if they maintain private coverage for themselves and any accompanying family.11Social Security Administration. Totalization Agreement with Japan The employer obtains a certificate of coverage from the Japanese social insurance agency to establish the exemption.
National Pension
Japan’s National Pension (Kokumin Nenkin) is mandatory for all residents between 20 and 59, regardless of nationality.12Japan Pension Service. Enrollment in National Pension If you’re employed, your company usually handles enrollment through the employees’ pension system. Self-employed residents and students enroll directly at the ward office. Monthly premiums are a flat amount adjusted annually; check the Japan Pension Service website for the current figure.
Foreign residents who leave Japan after contributing for at least six months but fewer than ten years can apply for a lump-sum withdrawal payment within two years of departure. The Totalization Agreement also allows pension contributions in both countries to be combined when calculating benefit eligibility, so years paid into the Japanese system aren’t wasted if you return to the U.S.13Social Security Administration.

Taxes and Financial Reporting for U.S. Citizens
This is where living abroad as an American gets complicated. You have tax obligations to both countries, and the reporting requirements are extensive enough that many expats hire a cross-border tax specialist. Ignoring them is not a workable strategy: penalties for non-filing are steep, and the IRS shares information with Japan.
Filing in Both Countries
The U.S. taxes its citizens on worldwide income regardless of where they live. You file a U.S. tax return every year, even if all your income comes from a Japanese employer and you’ve already paid Japanese income tax on it. Japan requires its own filing through the National Tax Agency on income earned there. Two IRS mechanisms keep you from being taxed twice on the same income:
- The Foreign Earned Income Exclusion (FEIE): For tax year 2026, you can exclude up to $132,900 of earned income (salary, self-employment) from U.S. taxation. You must pass either the physical presence test — being in a foreign country for 330 full days during a 12-month period — or qualify as a bona fide resident of Japan. The FEIE only covers earned income; it does not apply to investment income, rental income, or capital gains.14Internal Revenue Service. Foreign Earned Income Exclusion – Physical Presence Test
- The Foreign Tax Credit (FTC): Filed on IRS Form 1116, this credit offsets your U.S. tax liability dollar-for-dollar for income taxes already paid to Japan. It covers both earned and passive income and is often more beneficial than the FEIE for higher earners, since Japanese tax rates can exceed U.S. rates. Unused credits carry forward up to ten years.
You can use the FEIE and FTC together on different categories of income, but not on the same income. Getting the combination right is the main reason expats hire specialists.
FBAR and FATCA Reporting
Once you open a Japanese bank account, you trigger separate financial reporting obligations that have nothing to do with owing tax:
- FBAR (FinCEN Form 114): If the combined balance of all your foreign financial accounts exceeds $10,000 at any point during the year, you must file an FBAR electronically with FinCEN. The deadline is April 15 with an automatic extension to October 15, no request needed. Non-willful violations carry penalties exceeding $16,000 per account, and willful violations are far worse.15Financial Crimes Enforcement Network. Report Foreign Bank and Financial Accounts16Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
- FATCA (Form 8938): If your foreign financial assets exceed $200,000 at year-end or $300,000 at any point during the year for a single filer abroad, you must report them on Form 8938 attached to your tax return. For married couples filing jointly, the thresholds are $400,000 and $600,000 respectively.17Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers
FBAR and FATCA overlap but are filed separately: FBAR goes to FinCEN, Form 8938 goes to the IRS with your tax return. Many Americans in Japan file both.
Renewing Your Visa and Reaching Permanent Residency
Long-term residence visas expire, and renewal should start well before the deadline. You can apply for an extension beginning three months before your current visa’s expiration date.18Japan External Trade Organization. Extension of Period of Stay and Change of Status of Residence If you’ve applied but haven’t received a decision by the expiration date, you can legally stay for up to two months past it, or until the decision comes, whichever is sooner, while the application is pending.
Don’t let a visa lapse without filing for renewal. Overstaying, even by a day, creates serious problems for future applications and can result in deportation. If your circumstances have changed — new employer, marriage, divorce — you may need to apply for a change of status rather than a simple renewal, which is a separate process with its own documentation.
After living in Japan continuously for ten years, or as little as one year with 80 points on the Highly Skilled Professional system, you become eligible to apply for permanent residency, which ends the renewal cycle.
