>shikoku is poorly connected to honshu it does not make sense to group tokushima with keihanshin but not the western portion of the island.
it's the opposite. 4 prefectures in shikoku have no connection to each other because of mountainous landscapes, 3 of which except for Kochi have firm economic ties to the prefectures across the sea.
