Address and name changes became mandatory on April 1
Since April 1, 2026, an owner registered on the Japanese real-estate registry must generally register a change of address, personal name or corporate name within two years of the change. Previously, moving home or changing a name did not itself create a legal duty to update the property registry. The reform is part of Japan's response to the problem of land whose owners cannot be readily identified, with incomplete address-change registrations cited as one contributing cause. It applies broadly to owners of land and buildings, including condominiums, houses and investment property.
A new system can allow automatic registry updates
Alongside the obligation, the Ministry of Justice operates a mechanism often referred to as Smart Change Registration. Owners can provide search information in advance, allowing the Legal Affairs Bureau to identify later address changes and, after confirming the owner's intention where required, update the registry ex officio. The system can reduce the need for a new application each time an address changes, although procedures and required information differ between individuals and corporations.
Overseas owners should keep registry information current
The reform is especially relevant where a foreign or Japanese owner moves overseas while continuing to hold Japanese property. A mismatch between the registered address and the actual residence can complicate later sales, inheritance procedures and mortgage registrations. Overseas owners may also face separate requirements concerning proof of address and domestic contact details. For that reason, the 2026 change is not merely an administrative rule for domestic movers; continuing management of registry information is now a core compliance issue for anyone holding Japanese real estate.
