For that reason, it was common that the post of shogun was assumed before he was 10, and he was sent back to Kyoto in his 20's after he was resigned as Shogun; he would be appointed to Nakatsukasa-kyo (Minister of the Ministry of Central Affairs) or Shikibukyo (Minister of the Ministry of Ceremonial) after that.
そのため、就任は10歳前半までに行い、長じても20歳代までに将軍職を辞任して京都に返され、中務卿・式部卿などに任ぜられることが通例であった。
