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 Portugal 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.

Portuguese Civil Code (Código Civil) governs succession. As an EU member, Portugal applies the EU Succession Regulation (Brussels IV): the law of habitual residence applies by default, with the option to choose national law.

Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Saitama, Portugal succession law may govern inheritance rights — but Japanese tax law always determines the tax obligation on Japan-situs property.

Renvoi (反致): May Apply

Under Brussels IV, renvoi is generally excluded for intra-EU cases. For non-EU situations (assets in Japan), Portuguese conflict of laws rules under the Civil Code may refer to lex rei sitae for immovable property, resulting in renvoi to Japanese law.

Tax Obligation in Saitama

Saitama-Specific Inheritance Considerations

1.Saitama's Kurdish community (one of Japan's largest) may face unique inheritance issues related to refugee/asylum status and domicile determination

2.Agricultural land conversion (市街化区域内農地) is common in outer wards — these have special inheritance tax valuation and deferral rules

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