Japan has one of the world’s highest inheritance tax rates — with a top marginal rate of 55% on large estates. For foreigners living in Japan, the rules can be surprising: in many cases, your worldwide assets — not just those in Japan — can be subject to Japanese inheritance tax. This guide explains who is liable, how the tax is calculated, and what steps foreigners can take to plan ahead.
Does Japan’s Inheritance Tax Apply to Foreigners?
The short answer: yes, often. Japan’s inheritance tax can apply to foreign residents in ways that many are unprepared for.
Who Is Liable?
Japan’s inheritance tax liability depends on the residency status of both the deceased and the heir:
Unlimited Liability (全納義務者 — worldwide assets taxed):
- If the heir has been living in Japan with a residence card for any portion of the 10 years preceding inheritance, Japanese inheritance tax applies to worldwide assets — including assets held in other countries
Limited Liability (制限納税義務者 — Japan assets only taxed):
- If the heir has not been a resident in Japan in the past 10 years, only Japan-based assets are subject to inheritance tax
This means a foreigner who has lived in Japan for more than 10 years and inherits from a parent abroad could face Japanese inheritance tax on assets held entirely outside Japan.
Japan’s Inheritance Tax Rates (2025)
Japan uses a progressive tax rate on the taxable amount per heir:
| Taxable Amount per Heir | Tax Rate |
|---|---|
| Up to ¥10 million | 10% |
| ¥10M–¥30M | 15% |
| ¥30M–¥50M | 20% |
| ¥50M–¥100M | 30% |
| ¥100M–¥200M | 40% |
| ¥200M–¥300M | 45% |
| ¥300M–¥600M | 50% |
| Over ¥600M | 55% |
These rates apply after deductions are applied to the total estate.
Basic Deductions
Before calculating the taxable amount, key deductions reduce the estate:
Basic Deduction: ¥30,000,000 + (¥6,000,000 × number of statutory heirs)
For example, if the deceased leaves behind a spouse and two children (3 statutory heirs): ¥30,000,000 + (¥6,000,000 × 3) = ¥48,000,000 deduction
This means estates below approximately ¥48 million in this scenario face no inheritance tax — a meaningful threshold, but one that can be quickly exceeded when real estate is included.
Spouse Deduction: A surviving spouse can inherit up to ¥160 million or their legal share (whichever is larger) tax-free.
Minor Deduction: A deduction of ¥100,000 per year until age 18 applies for minor heirs.
Overseas Asset Issues
Japan’s worldwide taxation of long-term foreign residents has been criticized as creating double taxation — particularly when a foreign country also levies inheritance or estate tax. Japan has inheritance tax treaties with several countries (including the US, UK, France, and Germany) that may reduce this burden through foreign tax credits.
If you are from a country without a tax treaty with Japan, it is worth consulting a tax professional about your specific situation — especially if your parents or family members have significant assets abroad.
Planning Ahead: What Foreigners Can Do
The time to address inheritance tax exposure is before the inheritance event, not during. Options worth discussing with a specialist include:
Life insurance as a deduction tool: Life insurance proceeds paid to named heirs receive a special deduction: ¥5,000,000 × number of statutory heirs. This makes life insurance one of the most accessible tax planning tools for families in Japan.
Gifting (zoyo): Gifts of up to ¥1.1 million per year per recipient are tax-free. Systematic annual gifting can reduce estate size over time. Gifts between ¥1.1 million and higher amounts in a single year are subject to gift tax.
Real estate and business succession planning: Real estate values for tax purposes often differ from market values — a specialist can help assess this.
For families navigating the intersection of inheritance planning and life insurance in Japan, independent financial advisors can be genuinely useful. みんなの生命保険アドバイザーは全国相談無料！ offers free nationwide consultations with licensed advisors — with no obligation to purchase — and can help you understand what options are available to protect your family’s financial position in Japan.
Filing and Payment
If inheritance tax is owed, heirs must:
- File a return and pay tax within 10 months of the death of the deceased
- File at the regional tax office (zeimusho) in Japan
Missing this deadline can result in penalties and interest.
