Property Characteristics in Saitama
Mix of suburban residential areas and former agricultural land under development. Larger lot sizes than Tokyo. Many residential developments from the 1970s–1990s now entering inheritance cycles. Growing number of new condominiums near Omiya Station.
Applicable Law for Taiwan Nationals
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.
Taiwan's Civil Code (Book V: Succession) governs inheritance. Similar structure to Japanese civil code.
Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Saitama, Taiwan succession law may govern inheritance rights — but Japanese tax law always determines the tax obligation on Japan-situs property.
Renvoi (反致): May Apply
Taiwan's conflict-of-law rules may result in renvoi to Japanese law for property located in Japan.

3.The merger of Urawa, Omiya, Yono, and Iwatsuki created complex former-jurisdiction records for older properties
