At first, Nyobo (a court lady) or Kinshin (close aide/trusted vassal) took the role of Moushitsugi, but in the Insei period (during the period of the government by the retired Emperor), favorite retainers among In no Kinshin (the retired Emperor's courtier) were working as Moushitsugi, including TAKASHINA no Yasutsune at Goshirakawa-incho (the retired Emperor Goshirakawa's Office), and Nobukiyo BOMON and Kintsune SAIONJI at Gotoba-in (the Retired Emperor Gotoba's Office); these people were involved in the government affairs through announcing Migyosho (documents for informing of decisions made by third or upper ranked authorities).
当初は女房や近臣がその役目を担っていたが、院政期には院近臣の中でも寵臣とされた人々が申次を務め、後白河院の高階泰経や後鳥羽院の坊門信清・西園寺公経がこれに相当しており、御教書の伝宣などを担当するなど国政遂行に深く関与した。
