One of the biggest issues with Pokemon is the servers, as so many people are playing the game it’s causing them to crash constantly. Though players are adapting, it is still frustrating to both player and developer. Furthermore, the server issues is causing the game to be released slowly all over the world, with many major countries not having the game available yet.
The biggest one arguably is Japan, which has a population which will no doubt take full advantage of Pokemon GO. In an interview with Forbes, Niantic CEO John Hanke says:
“At present, the server capacity is Japan is not powerful enough,” Hanke said. “We are working hard with our partners in Japan to enable the servers to keep up with the demand once the game goes online there. We expect it to be released by the end of July.”
He also notes that Korea and China are a little problematic too:
“Google’s map information system in Korea is limited due to security concerns over North Korea,” Hanke explained. “In China, however, it is technically possible, but difficult to introduce due to the many hurdles, or should I say, regulations, we’d have to clear to get it to users.”
