Changes generally must be registered within two years
Japan made address and name change registration mandatory for registered real estate owners from April 1, 2026. Guidance from the Tokyo Legal Affairs Bureau states that an owner whose address changes through relocation, or whose personal or corporate name changes, must generally register the change within two years. Owners whose details had already changed before the new obligation took effect are also required to update their registration by the end of March 2028. The reform is particularly relevant to owners who have held Japanese property for years under an old address.
Overseas relocation can create mismatches in the property register
A foreign owner may buy property while living in Japan and later return home or move to another country, leaving the address in the property register different from the current address. When the property is eventually sold, the seller's identity and continuity with the registered owner must be established, and evidence linking multiple addresses can become important. The new obligation shifts the system away from waiting until the next sale and toward updating the register within a defined period after the change.
International owners should preserve documentation of address history
An overseas owner may not have Japanese residence certificates or seal-registration documents, and the evidence needed to demonstrate an overseas address change can differ depending on the country and circumstances. The exact documents required for a particular registration need to be confirmed separately, but owners can reduce future transaction friction by checking whether their registered address matches current information and preserving records of each move. Managing registration information during ownership has therefore become a more significant compliance issue for non-resident owners after 2026.
