Tokyo: A drone carrying a small camera, a water bottle and a flare and marked with a radioactive sign was found on the rooftop of Japanese Prime Minister Shinzo Abe`s office on Wednesday, media reported.
The significance was not immediately clear, but a Japanese court on Wednesday approved the restart of a nuclear power station, rejecting worries about safety of nuclear power in the wake of the 2011 Fukushima radiation disaster.
Televised aerial footage from the scene showed what appeared to be a drone with propellers covered under cardboard and later a blue tarp. Dozens of police officers were seen crowding around the object.
Japanese broadcaster NHK said an official at the premier`s office found the drone and that the device was around 50 cm (20 ins) in diameter.
Abe is in Indonesia to attend an Asia-Africa summit. An official at the prime minister`s office declined to comment.
A small drone crashed in the grounds of the White House in January, raising pressure in the United States to clarify regulatory guidelines.
