The Chinjufu Shogun was granted regional autonomy in the form of military rule within Mutsu Province and Dewa Province, and as this position was formally one of an officer commanding the standing army on the border (in the case of the Seii Taishogun, it was commanding a temporary expeditionary force), it was not necessary for the holder of this title to live in Kyoto, which was very convenient for a regional leader.
鎮守府将軍は、陸奥国、出羽国内で軍政という形での地方統治権が与えられており辺境常備軍（征夷大将軍の場合は臨時遠征軍）の司令官という性格を持つが故に京都在住の必要が無く、地方政権の首領には都合が良かった。
