Japanese Prime Minister Shinzo Abe awoke on Wednesday to find a half-meter-wide drone, contaminated with trace levels of radioactive cesium, on the roof of his office in Tokyo. Of course this is nothing new for Washington where a drone crash-landed on The White House lawn in January and Chief Cabinet Secretary Yoshihide Suga said that Japan is looking to tighten laws governing drones (ahead of next year’s G7-summit and the 2020 Olympics).
