Japan on Friday passed laws to ban drones being flown over Tokyo 2020 Olympic sites and US military facilities as a measure aimed at preventing terror attacks. Under the new legislation, drone flights will be restricted over the Olympic sites as well as venues for the Rugby World Cup that kicks off this September.
Flying drones in densely populated areas are also forbidden but a foreign tourist received a warning from police last week after he flew one over the famous "scramble" crossing at Shibuya. And several people told police they had seen a drone-like object near the Imperial Palace ahead of the new emperor's first public appearance.
A broader public discussion about drones was prompted after a Japanese man was arrested in 2015 for landing a drone containing a bottle of radioactive sand from Fukushima on the roof of Prime Minister Shinzo Abe's office. Traces of radiation were detected but were reportedly too low to be a risk to human health.
The Tokyo District Court sentenced the man a two-year jail term, suspended for four years. Following the case, the government imposed tighter regulations for flying unmanned objects in urban and densely populated areas, as well as around airports.
