>>30534689With Kanto, Johto, Hoenn, and Sinnoh you've already seen pretty much every aspect of Japan. Besides part of Pokemon's appeal is that it's a worldwide icon, staying in Japan would get tiresome.
Although I do want an updated Kanto that's more urban like Tokyo.
>>30534755Hoenn heavily represents Japan's southern life, which has tropical weather and a lot of sea life culture. Sinnoh is the northern part of Japan which is more cultural and religious.
Kanto is supposed to be the greater Tokyo region but they fucked that up.
