The purpose of this article is to consider the Shigeoka-no-Kawahito’s achievements and the personnel affairs of the Onmyoryo in the ninth century. Shigeoka-no-Kawahito was Onmyoji who fl ourished in the ninth century. His works are well known because his books that wrote about Onmyodo the fi rst of such cases in Japan. But it may not presume that his works based only his ability. This article studies carefully his origins and the changing appointment of the Onmyo-no-kami (chief of the Onmyoryo) .Shigeoka-no-Kawahito was from Toki Family. Toki Family has produced people who was familiar with Rekido (the knowledge about almanac) in ninth century. Around the same time, there were some families that appeared technocrats, such as Tenmondo (astronomy) , Sando (mathematics) and Ido (medicine) , one after another. This trend is understudied the rudiments of Kanshiukeoisei system that is the hereditary government offi ce system. In previous works, the hereditary of the office will be the guide about this system.However, people should learn high expertise in the family if they appeared technocrats one after another. Because Toki Family wasn’t the hereditary of the offi ce in the Onmyoryo, Toki Family isn’t included the case about Kanshiukeoisei system.However, some families that didn’t appointed to the offi ce were learning expertise like Toki Family in early stage of this system. So Shigeoka-no-Kawahito used the knowledge that he learned in his family when he wrote books about Onmyodo.In addition, when Shigeoka-no-Kawahito worked in the Onmyoryo, it can confi rm the changing appointment of the Onmyo-no-kami. In other words, the person who was familiar with knowledge that associates to the Onmyoryo appointed Onmyo-no-kami. Especially, when Fujiwara-no-Namihuji worked Onmyoryo, it started to give the chance to change this trend. Many technocrats were employed in the Onmyoryo. That would cause to improve technology about Onmyodo, Rekido and Tenmondo.Shigeoka-no-Kawahito’s books appeared to the change term of the appointment system. As the result of systematizing Onmyodo, he wrote books about Onmyodo in ninth century.
