Property Characteristics in Sapporo
Wide streets and grid layout (modeled on US city planning). Lower density than other major cities. Significant tourism/resort property investment from overseas buyers. Building construction must account for heavy snow loads, affecting property valuation.
Applicable Law for Thailand 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.
Thailand's Civil and Commercial Code (Book VI) governs succession. Thai law applies to Thai nationals.
Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Sapporo, Thailand 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
Thai conflict-of-law rules apply the national law of the decedent without renvoi.
Tax Obligation in Sapporo
