Sakuji-bugyō (作事奉行) were officials of the Tokugawa shogunate having responsibility for architecture and construction matters. Appointments to this prominent office were usually fudai daimyōs. Conventional interpretations have construed these Japanese titles as "commissioner" or "overseer". The three loyal Tokugawa retainers were to become responsible for a number of shogunate building projects in the 1630s. The sakuji-bugyō was considered to rank approximately with the kanjō-bugyō and machi-bugyō.
