Inheritance and Gift Tax When You Move Back to Japan: What Changes the Day You Land

Jūsho: The Line Between Limited and Unlimited Liability

Japan's inheritance and gift tax reach depends on whether you have a jūsho, a registered tax domicile in Japan, not on your nationality.

Japan's inheritance and gift tax rules sort every taxpayer into one of two categories, and the category is decided by jūsho, meaning where your actual living base is, not by passport or visa type. A "居住無制限納税義務者" (resident unlimited taxpayer) is anyone who has a jūsho in Japan at the moment they receive an inheritance or a gift. That status pulls in worldwide assets: the Tokyo apartment, the pension you left overseas, the brokerage account in your old country, all of it. A "制限納税義務者" (limited taxpayer), by contrast, owes tax only on assets physically located inside Japan. If you spent years abroad as a non-resident with no Japan address, you were most likely a limited taxpayer, and only your Japan-based property was exposed.

The switch is not gradual and it does not wait for a grace period. Once you complete your move-in registration (tennyū todoke) at the ward office and your resident record shows a Japan address, the National Tax Agency treats you as having a jūsho from that point (National Tax Agency, No.4138). This is the practical trap for returnees: someone who inherits from an overseas parent a week after landing in Japan can already be inside the unlimited taxpayer bracket, with the entire estate, foreign real estate and foreign accounts included, subject to Japanese inheritance tax rules. That same registration also restarts your pension record; see our pension guide for people returning to Japan for how totalization and the lump-sum withdrawal decision change once you land.

This is a different problem from end-of-life planning itself. Our end-of-life planning guide for foreign retirees in Japan covers writing a will, repatriating remains, and coordinating heirs across borders for people who plan to stay in Japan long term. This article is narrower: it is about the day your own tax classification flips because you moved back, and what that means before you have written anything down.

Rates and the Base You Are Taxed On

Japan's inheritance tax rate runs from 10% to 55% depending on each heir's statutory share after deductions, among the highest schedules in the world.

The tax is calculated on the taxable estate after a basic deduction (¥30 million plus ¥6 million per statutory heir), then split notionally among heirs by their statutory share and run through a bracket table before being reassembled and apportioned by actual inheritance (National Tax Agency, No.4155). The top bracket, 55%, applies only to the portion of a statutory share above ¥600 million, but even mid-size estates with a Japan property and an overseas pension account can land in the 30 to 40% brackets once foreign assets are added in. Gift tax during life uses a steeper, separate bracket table because it is designed to discourage using lifetime gifts to dodge the inheritance schedule.

The practical planning question for a returnee is rarely the rate itself. It is whether foreign assets enter the calculation at all, which is exactly what your jūsho status decides. A returnee who keeps significant assets abroad and re-establishes a Japan address without first getting professional advice can convert a limited-taxpayer, Japan-only exposure into a worldwide one overnight.

The 10-Year Look-Back for Japanese-National Heirs

A Japanese-national heir who lives abroad can still be an unlimited taxpayer if they had a Japan address at any point in the 10 years before the inheritance.

The reverse scenario matters as much as your own status: what happens to your children or spouse if they stay overseas after you move back to Japan. For heirs who hold Japanese nationality, the National Tax Agency's rule is that living outside Japan at the time of inheritance does not automatically make them a limited taxpayer. If that heir had a jūsho in Japan at any point within the 10 years before the inheritance or gift, they remain a resident unlimited taxpayer and their worldwide assets, including property they own entirely outside Japan, are drawn into the calculation (National Tax Agency, No.4138). Only a Japanese-national heir with no Japan address at all in that 10-year window becomes a limited taxpayer.

For heirs who do not hold Japanese nationality, whether worldwide assets are taxed is decided mainly by the status of the person leaving the assets, not by the heir's own residence history. If you, the returning parent, have a Japan jūsho at the time of death, or had one at any point in the 10 years before it, a non-Japanese heir with no Japan ties is generally still an unlimited taxpayer, and their overseas property is drawn into the calculation. The heir falls into limited-taxpayer status, taxed on Japan-based assets alone, only when the person who died was a non-resident decedent with no Japan jūsho at death and none in the preceding 10 years. Because moving back to Japan is exactly what re-establishes that jūsho, families often assume the reverse, so have a tax professional confirm the combination for your specific citizenship mix. This is the scenario the pension-and-tax article does not cover in depth, since it addresses income tax on pensions rather than the transfer-tax status of heirs; see our pension and tax guide for foreign retirees for the income-side rules that run alongside this.

Mapping Your Family's Exposure Before You Move

A returnee should map each heir's nationality and Japan residence history separately, because the tax status is decided family member by family member, not household by household.

Families with a mixed citizenship, for example a returnee who is a Japanese national moving back while an adult child who was born and raised overseas remains there, often assume the whole family shares one tax status. It does not work that way. Each recipient of an inheritance or gift is classified individually based on their own jūsho history and nationality. A returning parent can be a full unlimited taxpayer the day they land. An adult child who has never lived in Japan and holds only a foreign passport is classified on their own facts, but not in isolation from the parent: because that parent has re-established a Japan jūsho, the child is generally an unlimited taxpayer too on a later inheritance from them, with overseas assets in scope, rather than being taxed only on the Japan-based portion as many families expect.

This individual-by-individual classification is also why families repatriating an aging Japanese parent should map every heir's status before, not after, the move-in registration is filed. Once the returnee's own jūsho is set, the assets exposed to Japanese tax are fixed at that classification; the heirs' individual status is a separate, second layer that needs its own check.

Kokugai Zaisan Chōsho: The Overseas Asset Report

A resident (excluding certain new arrivals) with more than ¥50 million in overseas assets as of December 31 must file a kokugai zaisan chōsho by June 30 of the following year.

Separate from inheritance tax itself, Japan requires an annual overseas asset report, the kokugai zaisan chōsho, from any resident whose overseas assets exceed ¥50 million in total value as of December 31 of that year (National Tax Agency, No.7456). The report lists the type, quantity, and value of each overseas asset and is filed with your local tax office by June 30 of the following year. A returnee who lands mid-year and quickly re-establishes a jūsho, then still holds a former home, a brokerage account, or a pension balance overseas above that threshold at year end, is expected to file even in their first year back.

Filing on time carries a direct incentive: if unpaid tax is later found relating to an asset that was correctly listed on a timely kokugai zaisan chōsho, the underpayment penalty is reduced by five percentage points. Missing the filing, or omitting an asset that should have been listed, works the other way and adds five percentage points to any penalty found later. Deliberately false filing or a filing failure without reasonable cause can also carry a criminal penalty of up to one year's imprisonment or a fine of up to ¥500,000 (National Tax Agency, No.7456). The report exists independently of whether any tax is actually owed that year, so a returnee should not treat "I have not inherited anything yet" as a reason to skip it.

Non-Permanent Resident Status and Why It Matters for Timing

A non-Japanese national is treated as a non-permanent resident for income tax purposes for the first years back, but this status does not exempt overseas assets from inheritance or gift tax once a jūsho exists.

Income tax and inheritance tax use different definitions of residence, and returnees sometimes conflate them. For income tax, a non-permanent resident is a non-Japanese national whose total time with a Japan address or residence in the past 10 years adds up to five years or less; that status limits Japanese income tax to Japan-source income plus remitted funds. Inheritance and gift tax, however, are governed by the jūsho test described above, which does not carry the same five-year cushion. In other words, being a non-permanent resident for your pension and investment income does not shield your overseas assets from the inheritance tax net once your jūsho is in Japan. Families should not assume the two systems move together.

Gifts Made Before the Move

Gifts given before you re-establish a Japan address are judged by your tax status on the date of the gift, so timing a transfer before move-in registration is a real, professional-grade lever.

Because the unlimited taxpayer switch is tied to a specific administrative act, filing move-in registration and establishing a jūsho, the timing of any gift matters. A gift completed while you are still a limited taxpayer, before your jūsho is re-established in Japan, is assessed under the rules that applied on that date. Once you have filed tennyū todoke and your resident record shows Japan, later gifts fall under the unlimited taxpayer rules regardless of how recently you landed. This is exactly the kind of decision that needs a Japan-licensed tax accountant (zeirishi) before the move, not after, because reversing a completed gift or an already-filed registration is not realistic.

A separate rule adds urgency on the inheritance side too. Gifts made before someone's death are added back into the inheritance tax calculation for a look-back period that is being extended in stages from three years to seven years for gifts made from 2024 onward, with the full seven-year window applying to gifts made from 2031 (National Tax Agency, tax reform outline). A returnee planning to give assets to family before or shortly after moving back should account for this longer add-back period, not the older three-year rule some family members may still remember from before the reform.

When to Bring In a Zeirishi

JCC does not give tax advice; the role here is to flag the jūsho switch early enough that a returnee brings a zeirishi in before, not after, filing move-in registration.

Nothing above is tax advice, and the combinations of nationality, years of Japan residence, heirs' locations, and asset types are specific enough that generic rules can mislead a specific family. A zeirishi with cross-border inheritance experience can model your actual numbers, confirm whether a spouse or child abroad falls inside or outside the 10-year look-back, and advise on whether any pre-move step makes sense for your situation. What families can control on their own is timing: getting this review done before filing tennyū todoke, not after, because the jūsho switch is not something a later filing can undo.
