Kanto doesn't have an official flag, because the regions don't have official flags with the exception of Hokkaido because it's both the region and the prefecture (because, for some reason, there's only one prefecture on the island despite the fact that every other one of the main Japanese islands is divided into prefectures, including the smallest one, Shikoku). The Pokéball is probably used because it's the only region of Japan where the region in Pokémon it's based off of is straight up named after it
