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.

Swiss Civil Code (ZGB, Book 3: Erbrecht) governs succession. Switzerland's Federal Act on Private International Law (IPRG) applies the law of the decedent's last domicile for succession, but a Swiss national may choose Swiss law.

Renvoi (反致): May Apply

Swiss IPRG (Article 91) applies the law of the decedent's last domicile but recognizes renvoi. If the decedent was domiciled in Japan, Swiss conflict rules may refer to Japanese law.

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.

Japan has a tax treaty with Switzerland that may provide relief from double taxation.

Frequently Asked Questions

Does Switzerland have inheritance tax?

It depends on the canton. There is no federal inheritance tax. Most cantons exempt spouses and direct descendants, but some cantons tax other heirs at rates up to 50%. The canton of Schwyz has no inheritance tax at all.

How did the 2023 Swiss succession reform affect forced heirship?

The January 2023 reform reduced the forced heirship (Pflichtteil) for descendants from 3/4 to 1/2 of their statutory share. Parents' Pflichtteil was eliminated entirely. This gives testators significantly more freedom to distribute their estate.

Which law applies — Swiss or Japanese?

Under Japan's conflict of laws, Swiss law applies as the national law. Under Swiss IPRG, the law of the decedent's last domicile applies, so if domiciled in Japan, Swiss rules may refer back to Japanese law (renvoi).
