The Monster Catching location-based mobile app, Pokemon Go that has been busy breaking all the major records like it has surpassed Twitter in daily active users and hit 70 million downloads within 21 days of its release, has also put security and government officials of many countries into trouble.

Likewise, Pokemon Go has been released in Japan just a few days back and officials in Hiroshima are already worried that the Pokemon Go players will disrupt their upcoming annual ceremony.

The method of playing the game is very simple, Pokemon Go players just have to get out of their homes and find the pokemons that are hiding near their place by using the location map on their smartphone screens. The places where pokemons are hiding are called Pokestops.

Japan’s Hiroshima Peace Memorial Park and United States Holocaust Memorial Museum are one of major Pokestops for the Pokemon-Go players. But on the other hand, every year on August 6, the park celebrates the dropping of the first nuclear bomb amid the World War II. For now, city authorities are planning to maintain a strategic distance from Pokemon Go players walking through the yearly function and cause distractions.

The Press reports that authorities asked Niantic (the developer of Pokemon Go), to Delete Pokestops and other virtual destinations before the function date, however the organization told the Press it would not make any conferences with an outsider.
