Japan Inheritance Tax Rate for Foreign Nationals

Japan's top inheritance tax rate is 55% — one of the highest in the world. But the actual tax liability for foreign nationals depends heavily on visa classification, length of residency, and whether the heir lives in Japan or abroad. Get the visa distinction wrong and you could be taxed on worldwide assets when you should only owe on Japanese-situs property.

The Tax Rate Table

Japan's inheritance tax is progressive, applied to each heir's individual share of the estate after the basic exemption:

The Basic Exemption

Not every estate owes inheritance tax. The basic exemption is:

JPY 30,000,000 + (JPY 6,000,000 x number of legal heirs)

For a surviving spouse and two children, the exemption is JPY 30M + (JPY 6M x 3) = JPY 48,000,000 (roughly USD 310,000). If the net taxable estate falls below this threshold, no tax return is required.

The Spouse Credit

The surviving spouse receives an additional major tax benefit: no inheritance tax on the lesser of their statutory share (typically 1/2 of the estate) or JPY 160,000,000 (roughly USD 1,030,000).

This is an enormous deduction — but it has a critical condition. To claim it, the inheritance tax return must be filed on time. A late filing forfeits the spouse credit entirely, potentially turning a zero-tax situation into a massive liability.

Which Assets Are Taxed: The Visa Classification Split

This is where it gets consequential for expats. The scope of taxable assets depends on the visa type of both the deceased and the heir:

Table 1 visa holders (work visas — highly skilled professional, business manager, engineer, etc.) with 10 years or less of Japan residency in the past 15 years: only assets physically located in Japan are taxed. Overseas bank accounts, foreign real estate, and investments in the home country are completely exempt — provided the heir is also a temporary resident or non-resident.

Table 1 visa holders with more than 10 years of residency: worldwide assets are taxed. The temporary-resident exemption expires.

Table 2 visa holders (spouse of Japanese national, permanent resident): worldwide assets are taxed from day one. There is no temporary-resident protection. If you hold a spouse visa and your wealthy parent dies in Canada, the Japanese tax authority taxes that Canadian inheritance at up to 55%, even though your parent had no connection to Japan.

This distinction catches long-term expats and mixed-nationality couples off guard. A spouse visa holder who assumed they were only liable for Japanese-situs assets may face an unexpected worldwide tax bill.

The Filing Deadline

The inheritance tax return must be filed and the tax paid within 10 months of the date of death. All heirs file a single joint return.

The National Tax Agency does not extend this deadline because a foreign probate process is slow. US probate can take one to two years to release estate funds, but the Japanese tax clock doesn't stop. Heirs may need to pay the Japanese tax out of pocket or arrange bridge financing while waiting for foreign assets to clear probate.

If the estate division isn't finalized within 10 months, heirs should file a provisional return based on statutory shares, then amend once the actual division is agreed. Filing late — even by one day — forfeits the spouse credit and triggers penalty interest.
