I really don't know what you mean by "mirrored". Do you mean is it based off of the real world or not? Because the regions in pokemon are all based regions in japan and they also make references to real life locations ingame, for example, one of the journals in the pokemon mansion claims mew was discovered in south america, also one of poliwraths pokedex entries mentions the pacific ocean, the pokemon world is sort of like a parallel to our world.
