A two-year statutory deadline now applies
Japan's Ministry of Justice updated its guidance on September 7 concerning the information used for automatic address-change registration. Since April 1, 2026, registered owners of Japanese real estate have been legally required to register changes to their address, personal name or corporate name within two years of the change. A failure to comply without a justifiable reason may result in an administrative fine of up to ¥50,000. Changes that occurred before the new requirement took effect are also covered, with the ministry generally requiring action by the end of March 2028.
Smart Change Registration is designed to reduce the burden
Alongside the mandatory rule, the government introduced Smart Change Registration, under which a Legal Affairs Bureau can use official databases to identify address changes and update the real estate register ex officio. Individuals can submit search information such as their name, address, date of birth and email address in advance. When the required conditions are satisfied, the resulting official registration is not subject to registration and license tax. A related mechanism applies to corporations, although entities without the necessary corporate identification information may still need to file changes themselves.
Overseas owners require particular attention
The automatic process does not operate identically for every owner living outside Japan or for every foreign corporation because Japanese resident-register and corporate-number data may not be available. Non-resident owners should therefore not assume that the existence of the smart-registration system eliminates their filing responsibilities. Address discrepancies can also become an issue when a property is sold or mortgaged, potentially requiring additional documentation. Maintaining accurate registered ownership information has consequently become a more important part of long-term Japanese property ownership.
