Inheritance Tax in Japan for Foreigners: The Complete Guide
Japan’s inheritance tax can reach 55% — here’s what every foreign resident needs to know.
If you live in Japan as a foreigner, you may be surprised to learn that you could be subject to Japanese inheritance tax — not just on assets located in Japan, but potentially on your worldwide estate. Japan has one of the highest inheritance tax rates in the world, and the rules for determining who pays, on what assets, and how much can be remarkably complex for non-Japanese nationals.
This guide breaks down everything you need to know about inheritance tax (sozoku-zei, 相続税) in Japan as a foreign resident: the tax rates, exemptions, the critical “10-year rule,” filing requirements, and when you should seek professional help.

Japan’s inheritance tax (sozoku-zei) is levied on individuals who receive assets through inheritance. Unlike some countries where the estate itself is taxed before distribution, Japan taxes each individual heir on the portion they receive.
Key characteristics of Japan’s inheritance tax system:
- Tax on the heir: Each person who inherits assets is individually responsible for paying the tax on their share.
- Progressive rates: Tax rates range from 10% to 55%, making Japan’s rates among the highest globally.
- Basic exemption: A substantial basic exemption means many smaller estates are not taxed at all.
- Worldwide scope (potentially): Depending on the residency status of both the deceased and the heir, Japanese inheritance tax may apply to worldwide assets — not just those in Japan.
- Self-assessment system: Heirs are responsible for calculating, filing, and paying the tax within 10 months of the date of death.
📌 Key Point
Japan’s inheritance tax system taxes the heir, not the estate. Each heir calculates and pays tax on their individual share of the inheritance. This is fundamentally different from estate tax systems in countries like the United States or the United Kingdom.
Tax Rates and Basic Exemption
Japan uses a progressive tax rate structure for inheritance tax. The more you inherit, the higher the rate on the excess portion. Here is the current rate table:
| Taxable Amount per Statutory Share | Tax Rate | Deduction |
|---|---|---|
| Up to ¥10 million | 10% | — |
| ¥10 million – ¥30 million | 15% | ¥500,000 |
| ¥30 million – ¥50 million | 20% | ¥2,000,000 |
| ¥50 million – ¥100 million | 30% | ¥7,000,000 |
| ¥100 million – ¥200 million | 40% | ¥17,000,000 |
| ¥200 million – ¥300 million | 45% | ¥27,000,000 |
| ¥300 million – ¥600 million | 50% | ¥42,000,000 |
| Over ¥600 million | 55% | ¥72,000,000 |
The Basic Exemption Formula
Before any tax applies, a basic exemption (kiso-kojo, 基礎控除) is calculated using the following formula:
📌 Basic Exemption Formula
¥30,000,000 + (¥6,000,000 × number of statutory heirs)
Only the amount exceeding this exemption is subject to inheritance tax.
Calculation Example
Suppose a person passes away leaving an estate worth ¥80,000,000, with a spouse and two children (3 statutory heirs):
- Basic exemption: ¥30,000,000 + (¥6,000,000 × 3) = ¥48,000,000
- Taxable estate: ¥80,000,000 − ¥48,000,000 = ¥32,000,000
- This ¥32,000,000 is then divided according to statutory shares (spouse: 1/2, each child: 1/4), and the progressive rates are applied to each share to calculate a total tax amount.
- The total tax is then redistributed to each heir based on their actual inheritance ratio.
Note that the spouse has an additional major benefit: the spousal deduction exempts the spouse’s share up to ¥160,000,000 or their statutory share (1/2), whichever is greater. This often means the surviving spouse pays zero inheritance tax.
📝 Section Summary
- Tax rates range from 10% (up to ¥10M) to 55% (over ¥600M).
- Basic exemption: ¥30M + (¥6M × number of statutory heirs).
- The spouse can often inherit tax-free thanks to the spousal deduction.
- Estates below the basic exemption threshold require no filing at all.
The 10-Year Rule: When Foreigners Are Liable
The most critical question for foreigners in Japan is: which assets are subject to Japanese inheritance tax? The answer depends on the residency and domicile status of both the deceased and the heir.
Japan uses the concept of “domicile” (jusho, 住所) — essentially your primary place of residence — to determine tax liability. This is not the same as your visa type or nationality.
The Three Categories of Tax Liability
| Category | Condition | Assets Taxed |
|---|---|---|
| Unlimited Tax Liability | Heir has domicile in Japan, OR both deceased and heir had domicile in Japan within the last 10 years | Worldwide assets |
| Limited Tax Liability | Heir has no domicile in Japan AND neither deceased nor heir had domicile within the last 10 years | Japan-located assets only |
| Table Visa Exception | Heir holds a “Table 1” work visa and has lived in Japan for less than 10 years | Japan-located assets only (even if domiciled) |
The 10-Year Rule Explained
The so-called “10-year rule” works as follows:
- If either the deceased or the heir has had a domicile (jusho) in Japan at any point within the 10 years before the date of death, the heir may be subject to Japanese inheritance tax on worldwide assets.
- This means that even if you leave Japan, you may still be subject to Japanese inheritance tax for up to 10 years after departure.
- Similarly, if the deceased lived in Japan within the last 10 years, heirs anywhere in the world could potentially be subject to Japanese inheritance tax on worldwide assets.
⚠️ Warning
The 10-year rule can catch many foreigners off guard. If you leave Japan and a parent passes away within 10 years, you may still owe Japanese inheritance tax on assets located anywhere in the world. Planning ahead is essential.
The 2018 Table Visa Reform
In 2018, Japan introduced an important exception for foreigners on certain visa types. If the heir holds a “Table 1” visa (which includes most work visas such as Engineer/Specialist in Humanities, Intra-company Transferee, Business Manager, etc.) and has been domiciled in Japan for less than 10 years out of the last 15 years, they are subject to inheritance tax only on Japan-located assets.
This reform was designed to make Japan more attractive to international talent by ensuring that temporary foreign workers are not burdened with worldwide inheritance tax obligations.
📌 Key Point
The Table Visa Exception does not apply to permanent residents (PR holders). If you hold permanent residency in Japan, you are generally treated the same as a Japanese national for inheritance tax purposes, meaning worldwide assets may be subject to Japanese inheritance tax.
Comparison by Residency Status
| Your Status | Years in Japan | Taxable Scope |
|---|---|---|
| Work visa (Table 1) | Less than 10 years | Japan assets only |
| Work visa (Table 1) | 10+ years | Worldwide assets |
| Permanent resident | Any | Worldwide assets |
| Spouse visa | Any | Worldwide assets |
| Left Japan (within 10 years) | N/A | Worldwide assets (if conditions met) |
| Left Japan (over 10 years ago) | N/A | Japan assets only |
📝 Section Summary
- Foreigners domiciled in Japan may owe inheritance tax on worldwide assets.
- The 10-year rule can extend liability even after leaving Japan.
- Work visa holders (Table 1) in Japan for less than 10 years are taxed only on Japan-located assets.
- Permanent residents are treated like Japanese nationals for tax purposes.

Who Is Considered a Statutory Heir?
Japan’s inheritance tax calculation is based on the concept of statutory heirs (hotei-sozoku-nin, 法定相続人) as defined by the Japanese Civil Code. This is important because the basic exemption and the tax calculation method both depend on the number of statutory heirs — regardless of who actually receives the assets.
The Japanese Hierarchy of Heirs
Under the Japanese Civil Code, statutory heirs are determined as follows:
| Priority | Heir Category | Statutory Share (with spouse) |
|---|---|---|
| Always | Spouse | Varies by who else inherits |
| 1st priority | Children (including adopted) | Spouse 1/2, Children 1/2 (divided equally) |
| 2nd priority | Parents (lineal ascendants) | Spouse 2/3, Parents 1/3 |
| 3rd priority | Siblings | Spouse 3/4, Siblings 1/4 |
Higher-priority heirs exclude lower-priority ones. For example, if the deceased has children, the parents and siblings do not become statutory heirs.
Important Considerations for Foreigners
- Different from your home country: The statutory heir rules under Japanese law may differ significantly from the inheritance laws of your home country. Japan uses a “forced heirship” system where certain heirs have a legally protected minimum share (iryubun, 遺留分).
- Which law applies?: Under Japan’s conflict-of-law rules, succession is generally governed by the national law of the deceased. If a non-Japanese national dies while living in Japan, their home country’s succession law typically determines who inherits — but Japanese tax law still determines how much tax is owed.
- Wills: A will prepared in your home country may be recognized in Japan, but it must meet certain formality requirements. Conversely, a Japanese-format will may not be recognized abroad.
⚠️ Warning
The interaction between your home country’s succession law and Japan’s tax law can create complex situations. For example, your home country may determine who inherits, but Japan determines how much tax is owed. Cross-border inheritance situations almost always require professional guidance.
Taxable Assets and Valuations
Understanding which assets are taxable and how they are valued is essential for estimating potential inheritance tax liability. Japan’s valuation methods can differ significantly from market value, which can work in your favor in some cases.
Types of Taxable Assets
| Asset Type | Valuation Method | Notes |
|---|---|---|
| Cash & bank deposits | Face value | Including foreign currency accounts (converted at exchange rate on date of death) |
| Listed stocks | Lower of: date-of-death price or average of past 3 months | Most favorable price can be used |
| Real estate (land) | “Road-rate value” (rosen-ka) — typically 70-80% of market value | Significant discount compared to actual market price |
| Real estate (buildings) | “Fixed asset tax value” — typically 50-70% of market value | Additional reductions for rental properties |
| Life insurance proceeds | Amount received | Exemption: ¥5,000,000 × number of statutory heirs |
| Retirement benefits | Amount received | Exemption: ¥5,000,000 × number of statutory heirs |
| Overseas property | Fair market value (converted to JPY) | Only taxable if heir has unlimited tax liability |
| Business assets | Various methods depending on type | Special valuation rules for closely-held companies |
Deductions and Exemptions
Several deductions can significantly reduce the taxable estate:
- Debts and funeral expenses: Outstanding debts of the deceased and reasonable funeral costs are deductible.
- Life insurance exemption: ¥5,000,000 per statutory heir is exempt.
- Spousal deduction: The larger of ¥160,000,000 or the spouse’s statutory share.
- Minor heir deduction: ¥100,000 × (18 minus the heir’s age) for heirs under 18.
- Disability deduction: ¥100,000 × (85 minus the heir’s age) for heirs with disabilities; ¥200,000 for severe disabilities.
- Small residential land deduction (kogata-takuchi): Up to 80% reduction in land value for the deceased’s primary residence (up to 330 square meters), subject to conditions.
📌 Key Point
The small residential land deduction (kogata-takuchi-to no tokurei) can reduce the assessed value of a home by up to 80%. This is one of the most powerful tools in inheritance tax planning, but eligibility requirements are strict. A tax professional can help determine if you qualify.
Gift Tax: The Related Tax You Should Know
Japan’s gift tax (zoyo-zei, 贈与税) is closely related to inheritance tax and serves as a safeguard to prevent people from avoiding inheritance tax by giving away assets before death. Understanding gift tax is essential for inheritance planning.
Annual Gift Tax Exemption
Each person can receive up to ¥1,100,000 per year in gifts without any gift tax liability. Gifts above this threshold are taxed at progressive rates that are actually higher than inheritance tax rates for the same amounts.
| Taxable Gift Amount | Tax Rate (general) | Tax Rate (from lineal ascendant to adult child/grandchild) |
|---|---|---|
| Up to ¥2 million | 10% | 10% |
| ¥2M – ¥3M | 15% | 15% |
| ¥3M – ¥4M | 20% | 15% |
| ¥4M – ¥6M | 30% | 20% |
| ¥6M – ¥10M | 40% | 30% |
| ¥10M – ¥15M | 45% | 40% |
| ¥15M – ¥30M | 50% | 45% |
| Over ¥30M | 55% | 55% |
Gift Tax and Inheritance Planning
- 7-year lookback rule: Gifts made within 7 years of death are added back to the taxable estate for inheritance tax purposes (previously 3 years, extended by 2023 reform).
- Settlement taxation system (sozo-ji-seisan-kazei): An alternative system allows gifts from parents/grandparents to adult children/grandchildren with a lifetime exemption of ¥25,000,000, but these gifts are then added to the estate at death for inheritance tax calculation.
- Special exemptions: Specific exemptions exist for housing funds (up to ¥10,000,000), education funds (up to ¥15,000,000 in trust), and marriage/childcare funds (up to ¥10,000,000).
⚠️ Warning
Gift tax rules apply the same domicile and 10-year rules as inheritance tax. If you are domiciled in Japan, gifts received from overseas may also be subject to Japanese gift tax. Do not assume that gifts from abroad are tax-free.
📝 Section Summary
- Gift tax exemption: ¥1,100,000 per recipient per year.
- Gift tax rates can be higher than inheritance tax rates for the same amounts.
- Gifts within 7 years of death are added back to the estate.
- The same 10-year / domicile rules apply to gift tax.

Tax Treaties and Double Taxation Relief
One of the biggest concerns for foreigners is double taxation — being taxed on the same inheritance in both Japan and their home country. Tax treaties and Japan’s domestic foreign tax credit system provide some relief.
How Tax Treaties Work
Japan has inheritance/estate tax treaties with a limited number of countries. These treaties typically establish rules for:
- Which country has the primary right to tax specific types of assets
- How to prevent the same asset from being taxed in both countries
- Credit mechanisms for taxes paid in the other country
Countries with Inheritance Tax Treaties with Japan
As of 2025, Japan has inheritance/estate tax treaties with only a small number of countries, including:
- United States
- United Kingdom (currently under the older convention)
For countries without a specific inheritance tax treaty, Japan’s domestic law provides a foreign tax credit (gaikoku-zei-gaku-kojo): if you pay inheritance or estate tax in another country on the same assets, you can credit that amount against your Japanese inheritance tax liability to avoid double taxation.
📌 Key Point
Even without a specific tax treaty, Japan’s foreign tax credit mechanism can help prevent double taxation. If you paid estate or inheritance tax in your home country on assets that are also taxable in Japan, you may be able to offset some or all of the Japanese tax. However, the calculation is complex and professional assistance is strongly recommended.
Practical Considerations
- Timing differences: Tax payment deadlines may differ between countries, creating cash flow challenges.
- Valuation differences: Japan may value the same asset differently than your home country.
- Currency conversion: Exchange rate fluctuations can affect the tax amount.
- Documentation: You will need to provide proof of foreign tax paid, which may require certified translations.
Filing Requirements and Deadlines
If the total value of inherited assets exceeds the basic exemption, the heirs are required to file an inheritance tax return and pay any tax due.
Key Deadlines
| Action | Deadline |
|---|---|
| Renounce inheritance (sozoku-hoki) | 3 months from learning of the death |
| File income tax return for the deceased (jun-kakutei-shinkoku) | 4 months from the date of death |
| File inheritance tax return and pay tax | 10 months from the date of death |
Who Must File
- Any heir whose inherited assets (after all deductions and exemptions) result in a tax liability.
- Even if no tax is owed, a return must be filed if you are claiming certain deductions (such as the spousal deduction or the small residential land deduction).
- All heirs typically file jointly using the same return form, although individual filing is also permitted.
Where to File
The inheritance tax return is filed at the tax office (zeimusho) with jurisdiction over the deceased’s last address in Japan. If the deceased had no address in Japan, special rules apply.
Penalties for Late Filing or Non-Payment
- Late filing penalty (mushinkoku-kasanzei): 15%–20% of the unpaid tax amount, depending on whether the taxpayer voluntarily files late or is discovered by the tax authority.
- Under-reporting penalty (kasho-shinkoku-kasanzei): 10%–15% of the underpaid amount.
- Delinquency tax (entai-zei): Interest charged on unpaid tax from the day after the deadline.
- Fraud penalty (juzei-kasanzei): 35%–40% for intentional underreporting or concealment.
⚠️ Warning
The 10-month filing deadline is strict. Unlike some other countries, Japan does not routinely grant extensions for inheritance tax filing. If the estate involves overseas assets, cross-border complications, or disputes among heirs, 10 months can pass quickly. Begin the process as soon as possible.
Installment Payment and Deferral
If paying the full tax amount at once is difficult, Japan offers two options:
- Installment payment (enno): Pay over up to 20 years in annual installments (with interest). Available when more than half the assets are illiquid.
- Payment in kind (butsu-no): Pay with inherited assets (such as real estate) instead of cash, as a last resort.
📝 Section Summary
- Filing deadline: 10 months from the date of death — no routine extensions.
- File at the tax office covering the deceased’s last address.
- Penalties for late filing range from 15% to 40% depending on circumstances.
- Installment payments are available for large, illiquid estates.
Why Foreigners Should Work with a Specialist
Inheritance tax for foreigners in Japan presents unique challenges that go far beyond a standard domestic case:
- Domicile determination: Establishing whether you have “unlimited” or “limited” tax liability requires careful analysis of your living situation, visa status, and history.
- Cross-border asset valuation: Overseas property, foreign investments, and business interests must be valued according to Japanese rules and converted to yen.
- Dual filing obligations: You may need to file in both Japan and your home country, coordinating timelines and foreign tax credits.
- Language barrier: All tax filings must be submitted in Japanese, and communication with the tax office is conducted in Japanese.
- Succession law conflicts: Your home country’s rules about who inherits may differ from Japan’s, creating complex legal situations.
- Tight deadline: The 10-month window leaves little room for error, especially when coordinating across countries and time zones.
A bilingual tax accountant (zeirishi) who specializes in international inheritance cases can navigate these complexities, ensure compliance with both countries’ requirements, and identify legitimate deductions and exemptions that could significantly reduce your tax burden.
