Moving to Japan for Americans

To work in Japan as an American citizen, you need a work visa. The process always starts with a Certificate of Eligibility (CoE), requested by your Japanese employer from the Immigration Bureau. Here are the main visa categories available:

Engineer / Specialist in Humanities / International Services

This is the most common visa for foreign professionals. It covers three areas: engineers, developers, and researchers in natural sciences (Engineer); professionals in law, economics, accounting, or marketing (Specialist in Humanities); and translators, interpreters, language teachers, designers, and public relations professionals (International Services).

Requirements: a university degree in the relevant field, or 10 years of professional experience (3 years for international services). Your salary must be at least equivalent to what a Japanese national would earn in the same role.

Highly Skilled Professional (HSP)

This points-based visa targets highly qualified profiles. A score of 70 points or more unlocks significant benefits: your spouse can work, and parents can join the household. With 80 points or more, permanent residency is accessible after just 1 year instead of 10. Criteria include degree level, annual salary, age, work experience, and a bonus if your university appears in certain international rankings. Degrees from top US universities (Ivy League, MIT, Stanford, etc.) score particularly well in this system.

Business Manager

This visa allows you to create or manage a company in Japan. Requirements include a minimum investment of 5 million yen (approximately $33,000 USD) or the employment of 2 full-time staff, along with a physical office in Japan.

Other options

The Working Holiday Visa (18-30 years old) offers 12 months with work rights under the Japan-US working holiday agreement. Spots are limited, so apply as early as possible.

The Spouse Visa gives you full access to the Japanese job market if your partner is Japanese. The Intra-Company Transfer visa applies to employees being relocated within the same international group, a common path for Americans working at multinationals with Japanese operations.

Tip: start the process at least 3 to 4 months before your planned departure date. The CoE takes 1 to 3 months to process, and the visa itself is issued within 5 to 7 business days at the Japanese consulate or embassy in the US (New York, Los Angeles, Chicago, Houston, or Honolulu).

For Americans used to the cost of living in New York, San Francisco, or Los Angeles, Japan is significantly more affordable, even in Tokyo. The current USD/JPY exchange rate makes the country even more accessible. The quality of services, safety, and public transit provide a daily experience that many American expats describe as a major upgrade.

Housing: the main expense

Housing is the largest single cost. There are several Japan-specific features to understand: key money (reikin) is a non-refundable gift to the landlord, typically 1 to 2 months of rent, though an increasing number of "foreigner-friendly" apartments have eliminated it. The security deposit (shikikin) is 1 to 2 months of rent, refundable at move-out minus cleaning fees (20,000 to 50,000 ¥). Agency fees can reach 1 month of rent plus tax. A guarantor (hoshonin) is mandatory: foreigners typically use a guarantee company (30% to 100% of one month's rent).

Budget 4 to 7 months of rent for upfront costs before moving in. A studio in Tokyo runs $500 to $900 USD per month. In Osaka or Fukuoka, expect $350 to $600. These figures are dramatically lower than comparable apartments in New York or San Francisco.

Tip: UR (Urban Renaissance Agency) and JKK Tokyo apartments require no key money, no renewal fees, and no agency commission. A great starting point for new arrivals.

Other expenses

Food runs about $300 to $500 USD per month. Japanese supermarkets are very affordable and a restaurant meal costs between $5 and $12. The monthly transit pass costs $50 to $90 depending on commute distance, and is often reimbursed by employers. National Health Insurance (NHI) contributions are roughly 8 to 10% of income, covering 70% of medical costs. A supplemental private insurance plan is recommended to cover the remaining 30%, especially for families.

Internet, phone and digital life in Japan

Japan has outstanding digital infrastructure, with a few quirks that expats should be aware of.

Fixed internet

Fiber optic (FTTH) is widely available. The main providers are NTT Flet's, au Hikari, and SoftBank Hikari. Expect around 4,000 to 5,000 ¥ per month ($27 to $33 USD) for gigabit speeds. Installation takes 2 to 4 weeks and may require landlord approval.

Mobile phone

The big three carriers (NTT Docomo, au (KDDI), SoftBank) offer full plans at 5,000 to 8,000 ¥ per month. Budget MVNOs like IIJmio, Rakuten Mobile, and Y!mobile offer unlimited data plans from 2,000 to 3,000 ¥ per month and are the recommended option for most expats. In your first weeks, a prepaid eSIM or Sakura Mobile (no residence card required to sign up) is the easiest solution.

Banking and payments

Opening a Japanese bank account can be tricky in the first months. Japan Post Bank (Yucho Ginko) is the most accessible for foreigners, and can be opened as soon as you have your Residence Card. Shinsei Bank offers an English-language interface, an international debit card, and a simplified opening process. SMBC Prestia is a multi-currency bank with English-language services, well suited to expats. Wise and Revolut are strongly recommended for USD/JPY transfers at a fraction of the cost of US banks.

Important note: Japan is still very much a cash society. Many local restaurants and small shops do not accept cards. Always carry cash.

The US-Japan Tax Treaty

The United States and Japan have a tax treaty in force designed to prevent double taxation. However, unlike most countries, the US taxes its citizens on their worldwide income regardless of where they live. This means that even as a tax resident of Japan, you are still required to file a US federal tax return every year.

The main tools available to reduce your US tax burden as an expat in Japan are: the Foreign Earned Income Exclusion (FEIE, Form 2555), which allows you to exclude a portion of your foreign-earned income from US taxation (up to approximately $126,500 for 2024); the Foreign Tax Credit (Form 1116), which lets you offset US taxes with Japanese taxes already paid; and the Foreign Housing Exclusion or Deduction for housing costs above a base amount.

FATCA and FBAR: mandatory reporting for Americans abroad

FATCA (Foreign Account Tax Compliance Act) requires US citizens to report foreign financial accounts and assets to the IRS using Form 8938 if they exceed certain thresholds. The FBAR (FinCEN Form 114) requires you to report any foreign bank accounts where the combined balance exceeded $10,000 USD at any point during the calendar year. Failure to comply carries severe penalties. These filings are separate from your tax return and have their own deadlines.

Income tax in Japan

The Japanese tax system is progressive. National income tax ranges from 5% to 45% depending on the bracket, plus a reconstruction surtax of 2.1% through 2037. Local tax (jumin-zei) is a flat rate of approximately 10% of income. For a salary of 5 million yen (roughly $33,000 USD), expect a combined effective tax rate of around 20 to 25%.

Tax residency status in Japan

If you have been in Japan for less than one year, you are a non-resident and taxed only on Japanese-source income at 20.42%. From 1 to 5 years, you are a non-permanent resident and taxed on Japanese income plus foreign income remitted to Japan. After 5 years, you are a permanent tax resident and taxed on your worldwide income, just like a Japanese national.

Social security: US-Japan Totalization Agreement

The US and Japan signed a Social Security Totalization Agreement that came into force in 2005. This agreement avoids double contributions and allows work credits from both countries to be combined for retirement eligibility.

On a secondment from a US employer (up to 5 years), you remain covered by US Social Security and are exempt from Japanese pension contributions. Your employer must obtain a Certificate of Coverage from the Social Security Administration (SSA).

On a local contract, you contribute to the Japanese system (NHI and nenkin). These contribution periods count toward your US Social Security eligibility, and vice versa.

US Social Security retirement benefits can be received abroad without interruption.

Practical advice: US expat taxation is among the most complex in the world. Before leaving, consult a CPA or tax attorney who specializes in US expat taxation. The cost of professional advice is far lower than the penalties for FBAR or FATCA non-compliance.
