The proposal for this system was based on a proposal for 'grant of yakuryo (executive allowance) to a person assuming an important post' given to Yoshimune by Tadataka SAKAI receiving treatments as a political adviser in the Yoshimune government when he saw that Nobutsune MATSUDAIRA (lord of the Sasayama clan) assuming Kyoto Shoshidai (the Kyoto deputy) had difficulties in performing duties only with an income from own territory.
この制度の提言は、吉宗政権で政治顧問的待遇を受けた酒井忠挙が、京都所司代の松平信庸(篠山藩主)が自らの領地からの収入だけでは任務に支障が生じていることを見て、吉宗に「重職役料下賜」を提言したことによる。
