As seen from these organizational changes, it is thought that a simple bureaucratic system was already being formed around the fifth century; there is an opinion that during this time, the "Yamato Kingdom", where the king's authority was the source of power, was replaced by the "Yamato administration", where a political organization, with a King at the center, held the power.
これにより、5世紀ごろには簡易な官僚制が形成されていたとして、それまでの王の権威を権力の源泉としていた「ヤマト王権」から王を中心とする政治組織が権力を担う「ヤマト政権」への転換がなされたとする見方もある。
