An architectural office captured images of the rooftop and walls of a turret at Osaka Castle on Monday using a drone, with the aim of offering renovation services for cultural assets.
The flying of drones in areas near the castle and other parks in the western Japan city of Osaka is prohibited, but the Osaka Chamber of Commerce and Industry helped the office gain special permission from the city as part of its initiative to promote new businesses.
The turret faces a moat, making visual observation of the walls difficult.
