The Abe administration is considering having a private entity assume practical work for regulating drone flights, such as identifying their operators, after one carrying a small amount of radioactive cesium was found on the roof of the prime minister's office last month, government sources said Monday.

While the administration and ruling parties are considering legislation to ban flights above important facilities, including the Diet and central government offices, the idea that drone buyers and users would be more efficiently managed by a private association has gained traction, the sources said.

Under the plan being floated, the identification of buyers would be obligatory, with such an entity as the Japan Radio Control Safety Association designated to take on the task, according to the sources.
