Japan Tax Residency Guide 2026 — Jūsho, Kyosho & the 5-Year Rule

Overview — The Two Residency Tests

Under Japanese tax law, an individual is a "resident" if they fall into one of two categories:

👉 Domicile (住所, Jūsho): A person who has a jūsho in Japan is a resident. Jūsho is the center of one's life — the place where a person habitually lives. Factors: primary residence (owned or long-term rental), family location, business base, registered address, and intention to stay indefinitely.

👉 Continuous Presence (居所, Kyosho): Even without a jūsho, a person who has continuously resided in Japan for 1 year or more is considered to have a kyosho and is treated as a tax resident. This catches long-term assignees and expats who may have maintained their domicile abroad.

👉 Non-Resident: A person who has neither a jūsho nor a kyosho in Japan — typically short-term visitors, business travelers, and those posted for less than 1 year who maintain their life base abroad.

Jūsho — Domicile (住所)

Jūsho is the primary test for residency. It is determined by objective facts, not formal registration:

👉 Objective Factors: Having a home in Japan that is more than transient (owned or rented on a long-term lease), living with family (spouse, children) in Japan, having your primary economic interests in Japan (employment, business, investments), maintaining a Japanese bank account, driving license, health insurance, and registered address (住民票), and spending the majority of your time in Japan.

👉 Intention: Your subjective intention and actions matter. If you arrive on a 3-year work visa with your family, you have clearly established jūsho. If you are on a 6-month assignment without family and maintain your home abroad, you may not have jūsho.

👉 Registration Is Not Determinative: Registering your address at the municipal office (住民登録) is strong evidence of jūsho but is not conclusive. A person can have jūsho without formal registration, or be registered without having jūsho (in rare circumstances).

👉 Departure: Jūsho ceases when you physically leave Japan with the intention of not returning. Simply maintaining a registered address and occasional visits does not maintain jūsho if your life is clearly based elsewhere.

Kyosho — Presence (居所)

Kyosho is a secondary test that catches those who stay long-term without a formal domicile:

👉 1-Year Rule: If you have continuously lived in Japan for 1 year or more, you are deemed to have a kyosho and become a tax resident, even if you maintain your domicile abroad. The 1-year period is based on actual physical presence, not visa duration.

👉 Continuous Presence: Brief trips abroad (vacations, business trips, home leave) do not break continuity. The NTA looks at whether your physical presence in Japan is the norm, with absences being temporary exceptions.

👉 Examples:

• An employee on a 2-year assignment who keeps their family and home in the home country: still has kyosho after 1 year → resident.
• A student on a 4-year degree program: kyosho after 1 year → resident.
• A business traveler who visits Japan for 3 months at a time, returning for 1 month between visits: generally not kyosho (no continuous 1-year presence).

Permanent vs Non-Permanent Resident

Once classified as a resident, the next step is determining whether you are permanent or non-permanent:

👉 Non-Permanent Resident (非永住者):

• Definition: A person who has a Japanese domicile but has not been a Japanese resident for more than 5 years in the last 10 years.
• Tax Scope: Only Japanese-source income + foreign-source income remitted to Japan. Foreign income left abroad is not taxed.
• 5-Year Clock: Starts from the date you establish jūsho/kyosho in Japan. Residency in Japan prior to the current stay may count toward the 5-year limit if it was within the last 10 years.
• Ending Status: After 5 full years of residence, you become a permanent resident automatically. This can be accelerated if you had previous Japanese residency within the last 10 years.

👉 Permanent Resident (永住者):

• Definition: Japanese citizens, or foreign nationals with a Japanese domicile for more than 5 years in the last 10 years.
• Tax Scope: Worldwide income — all income from both Japanese and foreign sources, regardless of remittance.
• Exit Tax: Subject to exit tax on unrealized gains if holding JPY 100M+ in specified securities upon departure.
• No Remittance Benefit: The remittance rule no longer applies. All foreign income is taxable.

The 183-Day Rule and Tax Treaties

While Japanese domestic law does not use 183 days as a residency test, tax treaties commonly do:

👉 Treaty Context: Most of Japan's double taxation agreements provide that employment income is taxable only in the employee's country of residence if: a) the employee is present in Japan for 183 days or less in any 12-month period (or calendar year, depending on treaty), b) the employer is not a Japanese resident, and c) the salary is not borne by a Japanese permanent establishment of the employer.

👉 Domestic Law vs Treaty: You can be a Japanese resident under domestic law (kyosho >1 year) but still claim treaty protection for employment income if you meet the 183-day test. This is common for short-term assignees who maintain their home country ties.

👉 Counting Days: Days of physical presence in Japan count — including partial days, weekends, and holidays. Travel days to/from Japan typically count as days present. Brief trips abroad do not reset the 183-day count but subtract from total presence.

Ceasing Residency — Leaving Japan

Your Japanese tax residency ends when you no longer have a jūsho or kyosho in Japan:

👉 Jūsho Termination: Jūsho ends when you physically leave Japan with the intention of not returning. Objective evidence: selling/terminating your lease, moving your family abroad, resigning from Japanese employment, registering your departure (転出届), and establishing a new residence abroad.

👉 Final Tax Return: When leaving Japan, you must file a final tax return (準確定申告) within 1 month of departure for the period January 1 to departure date. This is required even if you would not normally file (e.g., employees with year-end adjustment).

👉 Tax Representative (納税管理人): Appoint a tax representative in Japan to handle ongoing tax matters if you will continue to have Japanese-source income (rental property, dividends, etc.) after departure. The representative handles filings, payments, and communications with the tax office.

👉 Exit Tax Check: If you are a permanent resident with JPY 100M+ in specified securities, exit tax may apply. File the necessary declarations and consider deferral options before departure.

Dual Residency and Treaty Tie-Breakers

When two countries both claim you as a tax resident, tax treaty tie-breaker rules resolve the conflict:

👉 OECD Model Tie-Breaker (most Japanese treaties):

1. Permanent Home: Is a permanent home available in only one country? → resident of that country.
2. Center of Vital Interests: If permanent home in both → where are your closer personal and economic relations?
3. Habitual Abode: If center cannot be determined → where do you habitually stay?
4. Nationality: If still unresolved → country of nationality.
5. Competent Authority: If still unresolved → the tax authorities of both countries negotiate.

👉 Application: If Japan claims you as a resident under domestic law (e.g., you have been in Japan 14 months) and your home country also claims residency, the treaty tie-breaker determines your single country of residence for treaty purposes. This affects which country has primary taxing rights over different types of income.

👉 Certificate of Residence: To claim treaty benefits as a Japanese resident (or non-resident), obtain a Certificate of Residence (居住者証明書) from your local tax office. This document confirms your residency status for treaty purposes.

Record-Keeping and Compliance

Proper documentation of your residency status is critical:

👉 Arrival Date: Keep records of your flight/travel documentation showing your arrival date in Japan. This is your residence start date.

👉 Residence Registration: Maintain copies of your Residence Certificate (住民票), lease agreement, and utility bills showing your Japanese address. These support your claim of jūsho (or absence of it).

👉 Days in Japan Tracker: Keep a diary or log of days spent inside and outside Japan. This is essential for treaty claims (183-day test) and for demonstrating the extent of your presence. Immigration records (入国記録) from the Immigration Services Agency can be requested to verify.

👉 Foreign Income Records: For non-permanent residents, maintain detailed records of foreign-source income and remittances to Japan. Separate bank accounts for foreign income vs Japanese income are strongly recommended.

FAQ

What makes someone a Japanese tax resident?

Having a jūsho (domicile — center of life) in Japan, OR having a kyosho (continuous presence) for 1+ years. Residents are then classified as permanent (>5 years, worldwide taxation) or non-permanent (≤5 years, limited taxation).

What is the difference between jūsho and kyosho?

Jūsho is your domicile — the center of your personal and economic life. Kyosho is physical presence — if you live in Japan for 1+ years, you have a kyosho even if your domicile remains abroad. Both make you a tax resident.

How long can I stay in Japan without becoming a tax resident?

Up to 1 year without establishing kyosho, provided you do not establish jūsho (by maintaining your life center abroad). Practically, if you keep your home, family, and economic ties abroad and your stay is clearly temporary, you may remain a non-resident for up to 12 months.

When do I transition from non-permanent to permanent resident?

After 5 years of residence in the last 10 years. The clock starts from the date you establish jūsho or kyosho. Once you pass 5 years, all worldwide income becomes taxable in Japan — the remittance rule no longer applies.

How does Japan count days for the 183-day rule?

Partial and full days of physical presence count. The 183-day rule is in tax treaties (not domestic law) and is used for employment income exemption, not for determining residency itself. Always check your specific treaty wording.

Do I need to file a final tax return when leaving Japan?

Yes, a final tax return (準確定申告) must be filed within 1 month of departure for the period January 1 to departure date. This applies even if your employer did year-end adjustment.

What is a tax representative (納税管理人)?

A Japanese resident you appoint to handle your tax affairs after you leave Japan. Needed if you continue to have Japanese-source income (rental property, dividends, etc.) after departure. The representative files returns and handles tax office communications.

Can I be a resident of two countries at once for Japanese tax?

Japan can claim you as a resident under domestic law while another country also claims you. Tax treaties resolve this through tie-breaker rules (permanent home, center of vital interests, habitual abode, nationality). Only one country is your treaty residence.
