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 Iran 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.
Iranian Civil Code governs succession, heavily based on Shia Islamic law (Jafari jurisprudence). Iran applies the nationality principle: Iranian law follows the decedent regardless of location.
Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Saitama, Iran succession law may govern inheritance rights — but Japanese tax law always determines the tax obligation on Japan-situs property.
Renvoi (反致): Generally Does Not Apply
Iran strongly adheres to the nationality principle and generally does not accept renvoi. Iranian law insists on applying to all Iranian nationals regardless of domicile or asset location.

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
