Guide to Real Estate Succession in Japan

Published on April 29, 2026 and written by Cyril Jarnias

Navigating the maze of real estate inheritance in Japan can be complex, for both residents and foreigners, due to the specific laws governing this area. Between designating heirs, tax implications, and rigorous legal procedures, understanding each step is crucial to ensuring a smooth transfer of assets. Through this article, we break down the complete procedure to guide you through this often obstacle-ridden process, while highlighting the key differences from Western inheritance systems that can surprise many unwary investors or successors.

Understanding Inheritance Laws in Japan

Japanese Inheritance Legislation and Its Impact on Real Estate Transfer

1. Key Laws and Basic Concepts of Inheritance

The Japanese inheritance system is primarily governed by Book V of the Civil Code (Articles 882 to 1050). Upon the death of the deceased, assets are transferred either by testamentary succession according to the will or by legal succession as stipulated by law.

• If a will exists, it takes priority.
• However, certain family members are guaranteed a minimum share called the statutory portion.

In the case of legal succession, the spouse is always an heir, and other heirs are determined in the following order:

• First order: children (in the absence of children, their direct descendants)
• Second order: parents or other direct ascendants
• Third order: siblings (with the possibility of representation for nephews and nieces)

The distribution for each person is also detailed in the Civil Code; for example, in the case of a spouse and children, each receives half.

2. Requirements for Registering Real Estate Property Rights and Transfer Procedures

When acquiring assets, including real estate, it is necessary to change the registration of property rights in the land registry. Following the amendment to the Real Estate Registration Law (effective in 2021), it is mandatory to apply for registration within three years of the real estate acquisition. Failure to comply with this obligation may result in sanctions or penalties.

The documents generally required include:

• The certificate of registration of real estate property rights in the name of the deceased
• Complete copies of family registers concerning the deceased and all legal heirs
• The will or the inheritance distribution agreement

These documents must be submitted in writing to the competent registration office.

3. Impact from a Tax Perspective

Gift and inheritance taxes are also important factors. The amount of tax varies depending on the estimated value of the real estate, which can result in a high tax burden for large estates.

Furthermore, if the property is transferred to a third party at an artificially low price, it may be considered a deemed gift and become taxable. It is therefore recommended to use appropriate valuation methods and consult experts.

Thus, in Japan, the management and transfer process of assets, including real estate, is carried out rigorously and transparently through the Civil Code and associated systems.

Challenges of Managing Real Estate Assets in International Inheritance

Challenges Spanning Multiple Jurisdictions

Inheritance law in Japan is based on the principle of “monism,” which generally applies the national law of the deceased. In contrast, many countries adopt “pluralism,” where the legislation of the country where the real estate is located applies. This difference tends to complicate inheritance procedures involving real estate abroad.

For example, if a Japanese person owned real estate in the United States or France, countries that adopt pluralism, local law would apply to that property. This therefore requires adapting to different legal systems depending on each country.

Procedures Required in Japan

Administrative and Legal Formalities

• Obtaining the Certificate of Inheritance Rights: A “legal succession information table” indicating the relationship between the deceased and all heirs, as well as the contents of the estate, is prepared, based on which a certificate is issued.
• Engaging an Expert: The collection of civil status documents and preparation of paperwork, which may occur across multiple jurisdictions, is best entrusted to experts such as notaries or specialized legal professionals.
• Collaboration with a Local Attorney: When dealing with assets located abroad, it is necessary to comply with the local probate system.

International Conventions and Tax and Transfer Impact

Japan is a signatory to the Hague Convention, which allows, under certain conditions, the validity of foreign wills. Additionally, tax obligations may arise in both Japan and abroad, requiring timely filings and verification of tax treaties to avoid double taxation.

Practical Advice

• Use of Multilingual Experts: Bilingual attorneys or notaries can be helpful when coordinating between different legal systems.
• Drafting Comprehensive Wills: Creating content that takes into account the laws applicable to each category of asset.
• Learning from Case Studies for Streamlining Strategies: For example, in the case of a person residing in Japan named A, after completing probate for a property located in the United States, using the Japan-U.S. tax treaty allowed for an adjustment of attributable income, subsequently reducing the time needed to complete the registration change in Japan by 4 months.

Key Steps to Inherit Property in Japan

1. Death Notification and Basic Administrative Procedures

To begin the inheritance process, the death of the deceased must first be reported to the municipal office. In this regard, a death certificate or a medical examination certificate issued by a doctor is required. The death notification must be submitted within 7 days of the date of death. This also allows for obtaining a cremation permit. Subsequently, related procedures such as the termination of public pension and health insurance rights must be pursued promptly.

2. Determining Heirs and the Role of the Family Register

To determine the legal heirs, it is necessary to have all continuous extracts from the family register from the birth to the death of the deceased, as well as current extracts of all potential heirs (spouse, children, etc.). The family register proves who the legal heirs are and is also essential for real estate registration and asset distribution negotiations.

Note that in Japan, the spouse is always a legal heir, with children as the first priority, parents as the second, and siblings as the third.

3. Asset Valuation, Property Management, and Tax Filing

For tangible assets such as real estate, a certificate of the land valuation value and an extract from the land registry are necessary to assess their value. For changing property ownership (name change), a will or an asset distribution agreement is also required.

Additionally, if the total value of the assets exceeds the basic deduction amount (30 million yen + 6 million yen × number of legal heirs), an inheritance tax return and payment are required within 10 months. However, tax reductions such as the spousal deduction are possible.

4. Consulting Experts and Advice for Efficient Management

To efficiently manage complex procedures, it is advisable to consult a certified public accountant, attorney, or notary. In particular, collecting numerous registers, real estate valuation, and tax management require specialized knowledge. Furthermore, paying attention to the many administrative deadlines helps avoid errors.

The Role of the Notary in International Inheritance in Japan

The Role of the Notary in International Estates in Japan

1. Legal Conditions for Notary Involvement in an International Estate

In Japan, a will made abroad can be valid if it meets certain conditions, in accordance with the “Law on the Law Applicable to the Form of Wills.” This law is based on the 1961 Hague Convention and presents several possible applicable laws, such as the law of the place of the act, the national law, or the law of the location of the real estate. Thus, the notary performs their duties by verifying these requirements. However, a notarial will, which does not require probate by the family court in Japan, is recommended.

2. Certification and Registration Procedure for an International Will

For drafting a notarial will, the presence of the notary and at least two witnesses is required. Furthermore, even if made abroad, it is implemented after verifying proper form and validity, in cooperation with local or foreign authorities (e.g., attaching translated documents or collaborating with local attorneys). It is also common to handle procedures separately depending on the location of the assets.

3. Involvement in Managing Real Estate in Japan

The notary also contributes to the management of inherited real estate, such as property valuation and rights verification. For inheritance registration, appropriate documents (e.g., the original will or its translation) must be submitted. To avoid conflicts, it is important to have a trusted third party pre-verify the contract content.

4. Fee Calculation Method and Problem Solutions

The fees for drafting a notarial deed, among others, are set by national regulations and vary depending on the scope of the case or the value of the assets. On the other hand, to reduce procedural costs, solutions such as using consular services or implementing prepayment strategies can be adopted. Furthermore, selecting experts and promoting understanding of private international law are essential for resolving multinational inheritance issues.

To facilitate these detailed and varied procedures, it is advisable to consult and engage an experienced notary with specialized knowledge.
