Many Japanese nationals living outside Japan are surprised to learn that Japanese inheritance tax may apply even when the inherited assets are located entirely outside Japan.

Japan's inheritance tax system is known for having relatively low exemption amounts and tax rates that can reach as high as 55% in certain circumstances. Depending on the residency history, nationality, and tax status of both the deceased person and the heirs, Japan may assert inheritance tax jurisdiction over assets located anywhere in the world.

As a result, families with ties to both Japan and the United States should be aware that U.S.-based assets—including a residence, retirement accounts, and investment portfolios—may, in some cases, be subject to Japanese inheritance tax.

Why Residency Matters

Whether Japanese inheritance tax applies often depends on a variety of factors, including:

• The nationality of the deceased and the heirs;

• Whether either party is considered a resident of Japan for tax purposes;

• The length of time either party has lived in or outside Japan; and

• The type and location of the assets involved.

Because these rules are highly technical and frequently amended, individuals considering a return to Japan or maintaining close ties with Japan should seek advice from a qualified Japanese tax professional.

Possible Planning Considerations

1. Understand the Tax Consequences of Moving to Japan

For Japanese nationals living abroad, a return to Japan may have significant inheritance and gift tax consequences. Before relocating, it may be worthwhile to discuss the potential tax implications with a Japanese tax advisor, particularly if substantial assets are located outside Japan.

2. Consider Lifetime Gifting Strategies

Japan provides certain annual gift tax exclusions. Making gifts during one's lifetime may, in some circumstances, reduce the value of assets that would otherwise be subject to inheritance tax.

However, Japanese gift tax rules are complex, and transfers made shortly before death may receive different tax treatment. Professional advice should be obtained before implementing any gifting strategy.

3. Coordinate U.S. and Japanese Estate Planning

A U.S. Living Trust may be an effective estate planning tool under U.S. law, but it does not necessarily reduce or eliminate Japanese inheritance tax exposure. Families with assets or family members in both countries should consider obtaining coordinated advice from professionals familiar with both U.S. and Japanese estate planning and tax issues.
