Japan is calling for the Fukushima nuclear exclusion zone to become a no-go area for Pokemon.
According to the Guardian, Tokyo Electric Power Company Holdings Co. (Tepco), operator of the heavily damaged Fukushima No. 1 nuclear plant, has asked that the gaming app maker Niantic not place the virtual-reality characters and Pokestops there to help prevent encouraging players to enter dangerous areas.
Tepco said it has tested the Fukushima Daiichi plant, which was partially destroyed by the March 2011 disaster, the nearby Fukushima Daini plant and the Kashiwazaki-Kariwa plant in Niigata Prefecture and found Pokemon on-site.
The Fukushima governor, Masao Uchibori, said at a press conference that it was not good that people might enter nuclear plants or evacuation zones designated after the nuclear disaster on the hunt for Pokemon and that "the prefectural government will consider how to draw attention to this".
The city government of Nagasaki has already requested that Niantic remove Pokemon from Nagasaki Peace Park, which is maintained as a memorial to victims of the atomic bombing of the city in 1945.
"The Peace Park is a place for prayer," a city official said, adding that playing games there is not appropriate. The city plans to ask park visitors to refrain from playing Pokemon Go.
Niantic said it would modify the game if the company discovered problems.
