The Board of Chamberlains and Togu-shiki (the Board of the Crown Prince's Affairs) serve specifically as aides for Emperor family and the Crown Prince family respectively, so if the Crown Prince succeeds to the throne, all Togu-shiki move to the Board of Chamberlains with the new Emperor and Empress and most of the former Board of Chamberlains staff move either to serve for the Empress Dowager who was the Empress of Taiko-Tenno (the departed emperor) or to become Togu-shiki to serve new Crown Prince.
侍従職と東宮職はそれぞれ天皇一家、皇太子一家の側近奉仕という特質上、皇位継承があった場合、東宮職の職員は即位した天皇皇后について侍従職に移り、逆にもとにいた侍従職のほとんどの職員が、大行天皇の皇后であった皇太后の側近奉仕をする皇太后宮職に移るか、新皇太子の側近奉仕をする東宮職に移る。
