1. Applicable Law (準拠法)

Under Japan's Act on General Rules for Application of Laws (法の適用に関する通則法, Article 36), the inheritance of a person is governed by the national law of the decedent.

UK succession law varies by jurisdiction (England & Wales, Scotland, Northern Ireland). No forced heirship in England & Wales.

Renvoi (反致): May Apply

UK law refers movable property to the law of the domicile and immovable property to lex rei sitae. Renvoi may apply.

2. Tax Obligation Type (課税範囲)

Unlimited Taxpayer

Taxed on all worldwide assets.

Applies if: domiciled in Japan, OR foreign national with residence visa who has lived in Japan for 10+ years.

Limited Taxpayer

Taxed only on assets in Japan.

Applies if: not domiciled in Japan, OR foreign national who has lived in Japan for less than 10 years.

Note: While Japan has a tax treaty with United Kingdom, it does not cover inheritance tax. Relief must be claimed under domestic foreign tax credit provisions.

Tax Treaty Details: United Kingdom & Japan

Does NOT Cover Inheritance TaxSigned: 2006 | Relief: tax credit

Japan-UK Tax Treaty (日英租税条約, 2006)

Covers income tax and corporate tax. Does NOT cover inheritance tax. UK imposes IHT at 40% above the nil-rate band (£325,000). Double taxation relief relies on domestic provisions and UK's unilateral relief under IHTA 1984 §159.

Key Provisions:

  • Income/corporate tax credit provisions only
  • UK IHT unilateral relief under IHTA 1984 §159 for foreign tax paid
  • Japan domestic foreign tax credit (§20-2) for IHT paid to UK

United Kingdom Domestic Inheritance Tax

UK Inheritance Tax (IHT) applies at 40% on estates exceeding the nil-rate band of £325,000 (~¥62 million). Transfers between spouses are exempt. The residence nil-rate band adds £175,000 for a family home passed to direct descendants.

Note: Japanese inheritance tax applies to property in Japan regardless of United Kingdom's domestic tax regime. If both countries impose tax, relief is available through the bilateral tax treaty and/or Japan's domestic foreign tax credit (相続税法第20条の2).
