Property Characteristics in Tokyo
Heavy concentration of high-rise condominiums (タワーマンション) in central wards. Average property age 25+ years in residential areas. Leasehold (借地権) properties common in older neighborhoods — inheritance requires separate valuation of land rights.
Applicable Law for Ireland 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.
Ireland's Succession Act 1965 governs succession. Ireland opted out of the EU Succession Regulation (Brussels IV). Ireland follows common law conflict rules: domicile for movable property, lex rei sitae for immovable property.
Important: The applicable succession law is determined by nationality, not by the location of property. Even for property in Tokyo, Ireland succession law may govern inheritance rights — but Japanese tax law always determines the tax obligation on Japan-situs property.
Renvoi (反致): May Apply
Ireland follows common law conflict rules: immovable property follows lex rei sitae, movable property follows the law of the decedent's domicile. For real estate in Japan, Irish rules point to Japanese law.
Tax Obligation in Tokyo
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.
Applies if: not domiciled in Japan, OR foreign national who has lived in Japan for less than 10 years.
Double Taxation Warning: While Japan has a tax treaty with Ireland, 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 Ireland's domestic provisions.
Tokyo-Specific Inheritance Considerations
1.Tokyo's extreme land value range (¥220K–¥2.2M/㎡) means inheritance tax varies dramatically by ward
2.Minato-ku properties frequently exceed the basic deduction even for small plots
3.The Kougu Shotoku Jutaku Tochi (小規模宅地) special deduction can reduce land valuation by up to 80% for the primary residence
4.Tower mansion tax reform (2024) changed valuation rules for high-rise condominiums — upper floors are assessed higher
5.Tokyo has the highest density of English-speaking tax professionals in Japan
