Tepco has requested that the developer prevents Pokemon appearing in and around areas affected in Fukushima in an attempt to discourage players from entering the dangerous site.
Meanwhile in Japan, officials have asked the game developer to remove PokeStops from the atomic bomb memorial park in Hiroshima. The city wants them deleted by August 6, the date of an annual ceremony to remember the victims of the atomic bomb.
