>>54642618People get way too caught up on Region = Real Place. The regions are inspired by real places just, but it stops there. They are not analogues.
People also forget that the "regions" are part of a national area. People view the regions to closes with their irl countries.
Sure Kanto and Johto sare a physically similar location to irl Kanto and Kansai, but they're also part of a bigger national entity that includes every other region, including the ones not based on Japan.
The concept of "countries" as we have in irl doesn't seem to apply.
