Emperor Kōnin
This office was typically filled by a son or close relative of the emperor. For example, in 773 ("Hōki 4"), the "daigaku-no-kami" was Yamabe"-shinnō", who was named Crown Prince and heir of Emperor Kōnin. However, there were exceptions to this general rule if there was an especially pre-eminent contemporary scholar, such as in the case of Miyoshi Kiyotsura.
