Japan Inheritance Tax for Foreign Property Owners: What Heirs Actually Pay

Japan has one of the heaviest inheritance taxes in the developed world, and a Japanese house or apartment is squarely inside its reach. For foreign owners and their heirs, the rules are unforgiving: the property is taxed by Japan regardless of where anyone lives. This guide explains what heirs actually pay and how the process works.

Does Japan charge inheritance tax on property owned by foreigners?

Yes, Japan charges inheritance tax on real estate located in Japan no matter the nationality or residence of the owner or the heirs. Real property in Japan is treated as a Japan-situs asset, so it is always within the scope of Japanese inheritance tax even when both the deceased and the heirs lived entirely outside the country. The location of the property, not the people, is what triggers the tax.

This catches many foreign families by surprise. A holiday apartment in Tokyo or a ski property in Niseko remains a Japanese taxable asset on the owner's death.

How much is the basic exclusion?

The basic exclusion is 30 million yen plus 6 million yen for each statutory heir. This means an estate with a spouse and two children has an exclusion of 30 million plus 18 million, or 48 million yen, before inheritance tax applies. Anything in the taxable estate above the exclusion is taxed at the graduated rates.

For a single property of significant value, this exclusion is often modest relative to Tokyo or resort real estate prices, so tax frequently does apply.

What are the inheritance tax rates in Japan?

Japanese inheritance tax rates are progressive, starting at 10 percent and rising to a top rate of 55 percent. The rates climb through brackets based on each heir's taxable share, with the 55 percent top rate reaching shares above 600 million yen. The tax is calculated on each statutory heir's portion under a formula, then reassigned according to how the estate is actually divided.

Because the scale rises steeply, mid-value and high-value Japanese properties can generate a substantial bill that heirs must fund, sometimes by selling the property itself.

Does the 10-year residency rule affect me?

The 10-year rule affects whether your worldwide assets are taxed, but it does not change the fact that Japanese real estate is always taxed. The rule looks at whether a person had a domicile in Japan within the 10 years before the death, and it determines exposure to inheritance tax on assets located outside Japan. For the Japanese property itself, none of this matters, because Japan-situs real estate is taxed in every case.

So if you own only a Japanese property and live abroad, that property is taxed, while your non-Japanese assets generally stay outside Japanese scope.

How is the property valued for inheritance tax?

Japanese real estate is valued for inheritance tax using official assessment methods rather than the open-market price. Land is generally valued using the National Tax Agency's roadside land price, known as rosenka, or a multiple of the fixed asset tax value where no roadside price exists. Buildings are valued at their fixed asset tax assessment value. These official figures are usually lower than the market price, which softens the tax base somewhat.

Because the valuation rules are technical, heirs of higher-value property almost always use a licensed tax accountant, a zeirishi, to prepare the calculation.

When is the inheritance tax due?

The inheritance tax return must be filed and the tax paid within 10 months of the date of death. This is a hard deadline, and missing it leads to penalties and interest. The 10-month window is tight when heirs live abroad, documents must be gathered, and the property must be valued, so families are wise to begin promptly.

Payment is generally due in a lump sum, though installment and payment-in-kind options exist in limited circumstances for those who cannot pay at once.

How do heirs transfer the title of inherited Japanese property?

Heirs transfer an inherited Japanese property through a registration called souzoku touki at the Legal Affairs Bureau. This updates the official property register to show the heirs as owners. Since April 2024, registration of inherited real estate is mandatory and must be completed within three years of the heir learning of the inheritance, with penalties for failing to register.

The registration requires the deceased's family register documents, proof of the heirs, and often a division agreement among them. Foreign heirs frequently appoint a judicial scrivener, a shiho shoshi, to handle the filing.

What happens if heirs live outside Japan?

If heirs live outside Japan, they remain liable for the inheritance tax on the Japanese property and must still file within the 10-month deadline. Living abroad does not remove the obligation, and heirs may need to appoint a tax agent in Japan to handle filings and receive correspondence. Gathering Japanese family register records and translating foreign documents adds time, which is why the deadline pressure is real.

Bektu advises foreign owners of Japanese property to document their holdings and intended heirs clearly while alive, since the combination of a 10-month tax deadline and a cross-border paper trail is the hardest part of any Japanese inheritance.
