Fujiwara no Nakamaro
Yakatsugu plotted with Fujiwara no Yoshitsugu, Ōtomo no Yakamochi, and Saeki no Imaemishi to overthrow the "daijō-daijin" and power of the day, Fujiwara no Nakamaro, but their plot was discovered. In 764, Yakatsugu was demoted to an assistant minister in the Dazaifu — until nine months later, when Nakamaro led his own failed rebellion. Yakatsugu was rehabilitated, promoted to , and made governor of Hitachi province.
