Japanese Inheritance Tax: Who Pays, Rates, and Deadlines

Japan’s inheritance tax is charged to each heir on what they personally receive, not to the estate as a whole, with a basic deduction of 30 million yen plus 6 million yen for every statutory heir and progressive rates that run from 10 percent up to 55 percent.¹ Whether you owe tax on worldwide assets or only on property located in Japan depends on your visa category and how long you have lived in the country. Estates below the deduction owe nothing and file nothing.

Who Actually Owes the Tax

Japan splits heirs into two groups. Unlimited taxpayers owe Japanese inheritance tax on every asset they receive anywhere in the world. Limited taxpayers owe tax only on assets located inside Japan.

You are an unlimited taxpayer if you have a domicile in Japan at the time of the inheritance and hold a status-based visa, which Japan’s immigration law classifies under Table 2. Permanent residents, spouses of Japanese nationals, and long-term residents all sit in Table 2. If you hold a work-related Table 1 visa instead (engineer, business manager, intra-company transferee, student, and similar categories), you are a limited taxpayer, but only until you have lived in Japan for more than ten of the previous fifteen years. Cross that line and you become an unlimited taxpayer regardless of visa type.

Switching to permanent residency also flips you to unlimited-taxpayer status immediately, because permanent residency is a Table 2 visa. This is the most common planning mistake: assuming a work visa permanently caps your exposure to Japanese assets, when in fact the ten-year clock or a residency upgrade can quietly change the answer.

Non-residents who inherit Japanese-situs property pay tax only on those Japanese assets. If both the deceased and the heir are non-residents without recent long-term ties to Japan, the tax generally reaches only property physically situated in Japan.

Which Assets Count and Where They Are Located

Japan classifies each asset by its physical or legal location. Real estate is located where the land sits, so a house in Tokyo is a Japanese asset and a house in California is a foreign asset. Bank deposits are located in the country where the account was opened. Stocks and bonds are located where the issuing company is headquartered. Patents and similar rights are located where they are registered.²

Unlimited taxpayers include every asset worldwide, from U.S. brokerage accounts to overseas rental properties and foreign retirement savings. Limited taxpayers include only what is located in Japan. Japanese-situs assets are always taxable regardless of the heir’s category.²

The taxable base is the gross value of these assets minus the deceased’s debts and funeral expenses. Mortgages, unpaid taxes, medical bills, and other documented liabilities all reduce the total before the basic deduction is applied.³

Gifts the deceased made to heirs within seven years before death get pulled back into the taxable estate. This lookback expanded from three years under a 2023 tax reform that took effect for gifts made on or after January 1, 2024. A 1-million-yen deduction applies to the added-back amount, but only for gifts made more than three years before death. Deathbed transfers do not escape the system.

Real estate is typically valued using the Roadside Value (rosenka) figures the National Tax Agency publishes annually, which run at roughly 80 percent of posted land prices. Bank balances are taken at the exact figure on the date of death. Life insurance payouts are included at the full benefit amount, though a non-taxable allowance of 5 million yen per statutory heir applies to proceeds designated for heirs. Foreign assets are converted to yen at the exchange rate on the date of death, and supporting documents need Japanese translations.

The Basic Deduction: The Threshold for Owing Anything

The deduction is 30 million yen plus 6 million yen for each statutory heir.¹ A married person with two children has three statutory heirs, producing a deduction of 48 million yen. If the net estate falls below the threshold, no tax is owed and no return is required.

Statutory heirs are defined by Japanese civil law, not by the deceased’s will. The surviving spouse always counts. Beyond the spouse, priority runs first to children (or grandchildren stepping into a deceased child’s place), then to parents if there are no descendants, then to siblings if there are no descendants and no living parents.⁴

Adopted children are capped for deduction math. If the deceased had biological children, only one adopted child adds to the heir count. If there were no biological children, up to two adopted children can count. Their actual inheritance rights are unaffected; only the deduction formula is limited.

Rates and How the Bill Is Built

The calculation runs in two steps.¹ First, subtract the basic deduction from the net estate, split the remainder according to statutory shares (spouse one-half with children, two-thirds with parents, three-quarters with siblings, and the other heirs splitting the balance), apply the progressive rates to each notional share, and add the results to get a total tax. Second, redistribute that total among the heirs in proportion to what each person actually received, then apply individual credits.

The rate brackets, applied to each heir’s notional statutory share, are:¹

Up to 10 million yen: 10 percent
10 million to 30 million yen: 15 percent
30 million to 50 million yen: 20 percent
50 million to 100 million yen: 30 percent
100 million to 200 million yen: 40 percent
200 million to 300 million yen: 45 percent
300 million to 600 million yen: 50 percent
Over 600 million yen: 55 percent

Because rates apply to each heir’s statutory share rather than the total estate, more statutory heirs push more of the estate into lower brackets. That is why the adopted-children cap exists.

The Spousal Credit and Other Reductions

The surviving spouse gets the largest break. The spousal credit erases tax on the greater of the spouse’s statutory share or 160 million yen.¹ A spouse who inherits alongside children (statutory share one-half) pays nothing so long as their portion stays within both one-half of the estate and 160 million yen. For most families, the surviving spouse owes zero.

Additional per-heir credits apply after the total tax is allocated:¹

Minor heirs: 100,000 yen for each year remaining until age 18.
Heirs with disabilities: 100,000 yen for each year remaining until age 85.
Heirs with severe disabilities: 200,000 yen per year remaining until age 85.

Filing Deadline and Payment

The return must be filed and the tax paid within ten months of the date of death. It goes to the tax office with jurisdiction over the deceased’s last place of residence in Japan, not the heir’s location. Each heir’s residency history and relationship to the deceased must be entered precisely, and errors in valuation or incomplete disclosure are where audits concentrate. Professional help from a Japanese tax accountant is worth the cost for any estate above the deduction.

Large bills often arrive before real estate or other illiquid assets can be sold. Two alternatives exist. Installment payments (enno) can spread the tax over up to twenty annual payments, with interest, and are generally available when more than half of the inherited assets are illiquid. Payment in kind (butsunou) lets heirs transfer inherited property, usually real estate, to the government instead of cash, subject to tax office approval of the specific assets. Both options require a formal application before the original ten-month deadline. Waiting until after the window closes does not shield you from late-payment penalties.

Penalties for Late or Incorrect Returns

Missing the ten-month deadline or underreporting values carries real cost.⁵ The standard late-filing penalty is 15 percent of the tax owed, rising to 20 percent on any amount above 500,000 yen and 30 percent on any amount above 3 million yen. Filing voluntarily before the tax office contacts you drops the penalty to 5 percent.

Underreporting on a timely return brings a 10 percent additional tax on the underpaid amount, rising to 15 percent for larger shortfalls. If the tax office finds intentional concealment, the penalty jumps to 35 percent for understatement or 40 percent for failure to file. Repeat offenders penalized within the previous five years face an extra 10 percentage points on top.⁵

If You Are a U.S. Person: Treaty Relief and Reporting

The United States and Japan have a dedicated estate, inheritance, and gift tax treaty, separate from the income tax treaty most people are familiar with.⁶ Its situs rules mirror Japan’s: real estate is taxed where the land sits, corporate shares are taxed where the company was organized, tangible personal property is taxed where it physically sits. When both countries tax the same asset, the country of the taxpayer’s domicile allows a credit for tax paid to the other, up to its own tax on that asset. The credit must be claimed within five years of the due date for the offsetting tax. For most U.S. persons that means a foreign tax credit on Form 706 for Japanese inheritance tax paid on assets also included in the U.S. estate.

A foreign inheritance is not U.S. taxable income. The potential overlap is between Japan’s inheritance tax on the recipient and the U.S. estate tax on the decedent’s estate, which the treaty coordinates.

The reporting obligations are what catch people. They create no additional tax, but the penalties for missing them are severe.

Form 3520

If you receive more than $100,000 in total from a foreign estate during a tax year, you must report it on Form 3520, identifying each gift or bequest above $5,000 separately. The form is due by April 15 of the following year, or the extended date if you have a filing extension. The penalty for not filing is 5 percent of the inheritance’s value per month, capped at 25 percent.⁷ On a $500,000 inheritance the cap works out to $125,000, for a form that carries no underlying tax. This is the single most commonly missed obligation in cross-border cases.

FBAR

Inheriting a foreign bank account, or gaining signature authority over one, triggers an FBAR filing with FinCEN if the combined balance of all your foreign financial accounts exceeds $10,000 at any point in the year.⁸ The deadline is April 15, with an automatic extension to October 15. The obligation applies even if you close the account the next day.

Form 8938

Inherited foreign financial assets may also trigger Form 8938 if your total foreign holdings exceed the FATCA thresholds. For unmarried taxpayers in the U.S., the threshold is $50,000 at year-end or $75,000 at any point. Married joint filers get double. Americans living abroad have thresholds of $200,000 at year-end or $300,000 at any point for single filers.⁹ Form 8938 goes to the IRS with your regular tax return; the FBAR goes separately to FinCEN. You may need to file both.

Japanese and U.S. deadlines run on different clocks. The Japanese return is due ten months after death, while U.S. informational filings are due the following April 15. Getting the Japanese return wrong can affect the foreign tax credit you later claim in the U.S., so coordinating advisors on both sides is worth the cost for any estate of meaningful size.
