Mix of traditional nagaya (長屋) row houses and modern condominiums. Ikuno-ku has many older properties with complex ownership histories. Expo 2025 development areas (Yumeshima) are seeing rapid valuation increases.
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 Osaka, 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 Osaka
Unlimited Taxpayer (無制限納税義務者)
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 (制限納税義務者)
Taxed only on assets in Japan.

Double Taxation Warning: While Japan has a tax treaty with Thailand, it does not cover inheritance tax. Relief must be claimed under Japan's domestic foreign tax credit (相続税法 第20条の2) or Thailand's domestic provisions.
