Well, but i like to think in the Logic that Yokai watch give in their Third game.

With the "American Yokais"

This emplies that Yokai (Spirits) aren't only found in Japan, but are globalized, just like humans, and that their appearances vary depending on the culture of that region.

Basically, a much more creative idea for "Pokemon Regions" and their "regional Pokémon," given the fact that they're based on a "monster collector."

And I remember that even Ghostbusters applied the same idea to regional Ghosts.
