Legal measures for unknown landowner problem?

What the Law Says

Japanese law provides mechanisms for managing land when the owner cannot be identified, prioritizing public interest and land utilization.

The Land Utilization Planning Act (LUPA) empowers local governments to designate 'land requiring utilization measures' when ownership is unclear and the land remains unused or underutilized. Under Article 35, authorities may issue recommendations or orders to promote proper use — including facilitating transfer or management by public entities.

The Act on Special Measures Concerning Land Registration (Act No. 134 of 2023) introduces streamlined procedures for registering land where the owner is unknown or unreachable. It permits registration of public bodies as provisional managers after publishing notices in official gazettes for at least six months.

If no claimant appears within the notice period, and the land has been publicly managed for two consecutive years without objection, the local government may apply for special registration allowing limited disposal rights — subject to compensation if the true owner later emerges.
