# How many days make you tax resident in Japan? > How Japan decides tax residency: the residence tests, the tax year (1 January – 31 December), the tests that catch you regardless of days, and National Tax Agency (国税庁)'s own page — checked 2026-08-18. Source: https://doastretch.com/tax-days/japan/ Japan · tax residency · 2026 Japan does not decide it on one number; the tests that do are below, with the official page. Next step **How we know** Figures are as National Tax Agency (国税庁) publishes them at nta.go.jp, checked 18 August 2026. Sources are listed further down the page. ## How the counting works From the NTA's 2025 INCOME TAX AND SPECIAL INCOME TAX FOR RECONSTRUCTION GUIDE, section 1-3. "Residents other than non-permanent residents are obligated to pay the income tax etc. for their whole income" — i.e. worldwide income. The NTA also states on its non-resident page: "You are considered as a non-resident in Japan for tax purposes unless you have a domicile or have had a residence continuously for one year or more in Japan." Note the common '183 days' figure does NOT apply to Japanese domestic residence — 183 days appears only in treaty short-stay articles. The tax year is the calendar year: income is assessed "during the year from January 1 to December 31 of that year". A special income tax for reconstruction of 2.1% of income tax applies for 2013 through 2037. ## Why the day count is the part you can control Ties, homes and intentions are argued after the fact; days are a record. That is why the first thing an adviser asks for is a list of the days you were in the country — and why reconstructing it from boarding passes and photos a year later is a bad afternoon. Log each stay as it happens and the tally is simply there, with the dates that produced it.

Three categories. RESIDENT: any individual who has a "JUSHO (domicile)" or owns a "KYOSHO (residence)" continuously for one year or more. NON-PERMANENT RESIDENT: among residents, any individual of non-Japanese nationality who has had a domicile or a residence in Japan for an aggregate period of five years or less within the preceding ten years. NON-RESIDENT: any individual who is not a resident. If a person who owns a residence in Japan leaves with the intent to be absent temporarily and later reenters, they are treated as having resided in Japan throughout the absence; temporary intent is presumed if during the absence (a) the spouse or relatives remain in the household in Japan, (b) the person retains a residence or a hotel room for residential use on return, or (c) personal property for daily use is kept in Japan for use on return. Count your days anyway — they are evidence, and other countries' tests use them. **When is Japan's tax year?** 1 January – 31 December. Day counts are measured against that year unless the rule names a different period — here, There is no day-count test. Residence turns on having a JUSHO (domicile) in Japan, or owning a KYOSHO (residence) in Japan continuously for one year or more.. **Are residents of Japan taxed on worldwide income?** Yes — once you are tax resident in Japan, worldwide income falls in scope, subject to double-tax treaties. Non-permanent residents are taxed only on (a) income other than foreign-source income, (b) foreign-source income paid in Japan, and (c) foreign-source income paid abroad and remitted to Japan. The remitted amount counted is, of the amounts remitted from abroad in the year, the excess over the income other than foreign-source income paid abroad in that year. This effectively gives non-Japanese nationals a remittance basis for their first five years of residence in any ten. **Is there a special tax regime for people moving to Japan?** Non-permanent residents are taxed only on (a) income other than foreign-source income, (b) foreign-source income paid in Japan, and (c) foreign-source income paid abroad and remitted to Japan. The remitted amount counted is, of the amounts remitted from abroad in the year, the excess over the income other than foreign-source income paid abroad in that year. This effectively gives non-Japanese nationals a remittance basis for their first five years of residence in any ten.
