Japan's National Police Agency has decided to deploy a new type of equipment called a "drone jamming gun" to prevent possible terrorist attacks.
The device uses radio waves to block the control signal of an illegal drone. Other countries, including the United States, have already introduced the technology.
The police agency plans to begin security personnel drills with anti-drone guns ahead of the G20 summit in Osaka in June, and the 2020 Tokyo Olympics and Paralympics.
Drones have been involved in various accidents and caused problems in Japan.
Spectators were injured when a drone crashed at an event in 2017 in Gifu Prefecture, central Japan. In 2015, a drone was found on the roof of the prime minister's official residence.
Last year in Venezuela, a drone loaded with explosives blew up in mid-air while President Nicolas Maduro was speaking at a military event.
