We have sat with owners who bought a quiet house in Kyoto or Shiga years ago and only later began asking the harder question. What happens to this place when I am gone? The answer is rarely simple when the people who will inherit live thousands of kilometres away.
Japanese real estate does not float free of Japanese rules just because the owner or the heirs hold foreign passports. The property sits in Japan, so registration, tax, and many practical steps stay firmly under Japanese procedures even when the governing succession law points elsewhere.
Who Inherits and Under Which Law
Japan’s Act on General Rules for Application of Laws generally looks to the nationality of the deceased to decide who the legal heirs are and what shares they receive. If the owner was a foreign national, their home-country law often governs the division of the estate.
That said, real estate located in Japan creates practical complications. The Legal Affairs Bureau still requires Japanese registration formalities. In some cases renvoi or the location of the property brings Japanese Civil Code rules back into play for the land and building themselves. Forced heirship (遺留分) under Japanese law protects certain close relatives—spouse, children, and parents—with reserved portions that a will cannot fully override. Siblings do not receive this protection.
A foreign will can be recognised in Japan if it meets the formal requirements of the place where it was made, the nationality of the testator, or other accepted connecting factors. In practice, executing a foreign will here usually means translations, authentication, and often an opinion from a local lawyer or judicial scrivener. It is possible, but it is slower and more expensive than a properly prepared Japanese will.
Inheritance Tax on Japan Property
Japanese inheritance tax is assessed on the person who receives the assets, not on the estate as a whole. Real estate located in Japan is a Japan-situs asset. Non-resident heirs almost always face Japanese inheritance tax on that property, regardless of their own nationality or where they live.
Whether overseas assets are also taxed depends on a matrix of residency history, nationality, and visa status for both the deceased and the heirs. The “10-year rule” is the practical shorthand: if both the deceased and the heir have been non-residents of Japan for more than ten years before the inheritance, foreign-situs assets generally fall outside Japanese tax. Japan-situs property does not.
There is a basic exemption of ¥30 million plus ¥6 million for each statutory heir. Rates then run from 10 % to 55 % on the taxable amount after the exemption. Filing and payment are due within ten months of the day after death. Non-resident heirs typically need to appoint a tax administrator (納税管理人) in Japan to handle correspondence and filings with the National Tax Agency.
The Mandatory Registration Deadline
Since 1 April 2024, inheritance registration (相続登記) has been compulsory. Heirs must apply to register the transfer of ownership within three years of the day they learn they have inherited the property. Failure without a valid reason can bring an administrative fine of up to ¥100,000. Properties inherited before April 2024 must be registered by 31 March 2027.
Overseas heirs cannot simply ignore the deadline. They must still complete the registration at a Japanese Legal Affairs Bureau. In practice this almost always requires a judicial scrivener (司法書士) in Japan. Foreign heirs usually cannot produce Japanese family-register extracts (戸籍謄本). Instead they provide equivalent documents from their home country—birth, marriage and death certificates, often with apostille or consular authentication—plus certified Japanese translations. Signature certificates replace the Japanese seal certificate (印鑑証明書). Since April 2024, overseas heirs must also register a Japan-based contact address for the property.
Practical Steps for Non-Resident Heirs
The process usually runs roughly like this:
- Confirm the governing succession law and identify all legal heirs.
- Gather and authenticate identity and relationship documents in the home country.
- Decide whether to accept the inheritance, accept it with limited liability, or renounce it entirely. Renunciation must be filed with a Japanese family court within three months of learning of the inheritance; it is all-or-nothing.
- Appoint a judicial scrivener and, if tax is due, a tax administrator.
- Complete the inheritance registration within the three-year window.
- File any required inheritance-tax return and pay within ten months.
Bank accounts, utilities, and fixed-asset tax notices continue in the meantime. Someone on the ground needs authority to deal with them.
Planning While You Are Still Here
The cleanest path for most foreign owners is to prepare a clear Japanese will (preferably a notarial will) that anticipates the reserved-portion rules, names an executor familiar with Japanese procedure, and makes the registration and tax steps as straightforward as possible for distant heirs. Appointing a reliable local contact or management company in advance also reduces the administrative load that falls on the family later.
We see the same pattern repeatedly. Owners who treat the property as a living asset while they are alive leave their heirs far fewer complications. Those who leave everything to chance often leave a tangle of deadlines, translations, and unexpected tax filings.
