Am I a tax resident of Japan?

Japan does not use a simple day count — residency turns on where your home and economic life actually are. Here is the test, and what it means once it applies.

The residency test in Japan

Japan does not test residency by a fixed day count. Instead the test looks at where your permanent home, family, and economic interests actually sit — a facts-and-circumstances test rather than a number to count against.

Non permanent resident status
A resident who is not a Japanese national and has lived in Japan for five years or less in the preceding ten years is a non-permanent resident, taxed on Japan-source income and on foreign-source income only to the extent it is paid in or remitted to Japan. Salary for work performed in Japan stays Japan-source even when it is paid abroad.

Temporary absence rule
A person who owns a residence in Japan and leaves only temporarily, intending to come back, is treated as still residing in Japan during the absence. The intent to return is presumed when family remain in the Japanese household, a residence is kept for after the return, or daily-use belongings stay in Japan. [source]National Tax Agency Japan (2025 Income Tax Guide)“If a person who owns a residence in Japan leaves Japan with the intent to be absent temporarily and later reenter Japan, the person shall be treated as having been residing in Japan during the period of absence.”View source · accessed 2026-09-26
Tax year period
1 January to 31 December (as of 2026)PwC Worldwide Tax Summaries“The Japanese individual income tax year runs from 1 January to 31 December.”View source · accessed 2026-09-26 — The individual income tax year is the calendar year, and the national return is due by 15 March of the following year. Returns are filed individually, as joint returns are not permitted.
Residency test
Japanese tax residence depends on having a domicile (jusho) in Japan or a residence (kyosho) held continuously for one year or more, not on counting days, so there is no 183-day residence threshold. Someone who arrives to take up an occupation that normally requires living in Japan for a year or more is presumed to have a domicile from arrival. [source]National Tax Agency Japan (2025 Income Tax Guide)“Any individual who has a “JUSHO (domicile)” or owns a “KYOSHO (residence)” continuously for one year or more is classified as a resident.”View source · accessed 2026-09-26

If your situation is borderline

With no day count to fall back on, Japan weighs facts a calendar can’t: where your home actually is, where your family lives, and where your economic life is centred. Two people with identical travel patterns can land on opposite sides of this test depending on those ties — a day-counter would not help either of them.

What residency actually changes

Once you are tax resident, Japan generally taxes your worldwide income, topping out at 55.945%Ministry of Finance Japan (Learning More About Taxes, June 2024)“For income from 2015, a new tax rate of 45% was created for taxable income exceeding 40 million yen to revive income redistribution function of the tax system.”View source · accessed 2026-09-26. The top combined marginal rate on ordinary income is 55.945%: 45% national income tax on taxable income above JPY 40 million, plus the 2.1% reconstruction surtax on that tax (45% x 1.021 = 45.945%), plus the flat 10% local inhabitant tax. From 2027 the surtax is split into 1.1% reconstruction and a new 1% defense surtax, which leaves the combined rate unchanged. Stay a non-resident, and Japan typically taxes only income sourced there.

When to talk to an advisor

This page maps Japan’s general residency test. It cannot weigh your treaty position, your specific ties, or the timing of a move. If meaningful money depends on the answer, have a qualified advisor in Japan (and in your home country) review your situation before you act.
