I visited Akihabara twice while in Japan. Once was for a meeting with a client company that was based there and the other was when I was exploring. This area is known for a lot of entertainment associated with animation and it has a lot of visitors that are into comics and animation. It also seemed to have a large number of people playing Pokémon Go judging by the way they were all standing around playing with their phones. I did see one guy with a phone and a tablet in both hands so he could play two games at once I guess. I’ve never played the game so I can’t speak to whether it is good or not but it still seems to be really popular.
