Apr 1, 2026 Ministry of Justice Inheritance, gifts & real estate In effect from April 1, 2024 (Reiwa 6). For earlier unregistered cases, the deadline is March 31, 2027 (Reiwa 9)

Inheritance registration is mandatory within 3 years; failure may bring a non-penal fine of up to JPY 100,000Changing the name on a house or land record is now a legal duty

An heir who acquires real estate by inheritance must apply for inheritance registration within 3 years from the day they learn of the acquisition. Failure without a justifiable reason is subject to a non-penal fine of up to JPY 100,000. Unregistered cases from inheritances before April 1, 2024 (Reiwa 6) are also covered, with a deadline of March 31, 2027 (Reiwa 9).

Duty after estate divisionSeparately, within 3 years of the divisionNot fulfilled by this
Public record of rightsYesNo
Sale or mortgagePossible as isInheritance registration required

Key points

  • The basic deadline is within 3 years from the day the heir learns that inheritance has begun and that they have acquired ownership (Real Property Registration Act, Article 76-2, paragraph 1)
  • When a division of the estate is agreed, registration based on its terms is also required within 3 years of the agreement date
  • Real estate from an inheritance known before April 1, 2024 (Reiwa 6) and still unregistered must be registered by March 31, 2027 (Reiwa 9)
  • The fine process: the registrar sends a demand first; if still not done, the court is notified. The court sets the amount, up to JPY 100,000
  • The inheritor declaration registration (相続人申告登記) simply fulfills the basic duty, but it does not fulfill the duty after an estate division and does not publicly record the rights
Who is affected: People who acquired land or buildings by inheritance, and owners of property whose register still shows the previous owner's name

What to do in practice

  • Check by registry certificates etc. whether any property is still in the name of a deceased person
  • If the estate division looks likely to drag on, consider the inheritor declaration registration within the deadline
Note: Examples of a justifiable reason include an extremely large number of heirs, or a dispute over the will or the scope of the estate. For individual cases, please consult the Legal Affairs Bureau or a judicial scrivener.

When the owner of a house or land passes away, the owner's name in the government record must be changed to the new owner. It used to be fine to leave it alone, but since April 2024 (Reiwa 6) it must be done within 3 years.

By when must it be done?
  1. April 1, 2024 (Reiwa 6)The duty begins
  2. Within 3 years of learning of itFor later inheritances, do the paperwork by this deadline
  3. March 31, 2027 (Reiwa 9)Deadline for unregistered inheritances from before the start

Points

  • Do the paperwork within 3 years from the day you learn you received the house
  • If you leave it without a good reason, you may have to pay a fine (called karyo) of up to JPY 100,000
  • Even for houses from people who died long ago and are still not registered, it must be done by March 31, 2027 (Reiwa 9)
For example: If there is an empty house still under your grandfather's name, you can't just leave it. You need to change the name before the deadline.

What the words mean

Inheritance registration (相続登記)
The paperwork to change the name on a dead person's house or land to the name of the person who received it
Karyo (過料)
