A businessman admitted Sunday to flying a drone that was found stuck the previous day among the roof tiles of Himeji Castle, a UNESCO World Heritage site in Hyogo Prefecture, the police said.

The 49-year-old executive from Kitakyushu was quoted by the police as saying that he was using the unmanned aircraft to take pictures of the recently renovated feudal fortress to post in a magazine. He reportedly contacted a police station in Kyoto on Sunday morning to claim responsibility for the accident.

The multirotor drone, measuring about 60 cm on all sides, was found on the fifth floor, the Himeji officials said, adding that a guard on a routine patrol in the morning spotted it flying at an altitude of about 46 meters. Its rotors were apparently broken during the crash.
