At the moment of the departure from the Takamanohara, Ninigi-no-mikoto was entrusted the sincere service to the Kagami, which was one of the Tree Sacred Treasures, in considering it to be the spirit of Amaterasu-oomikami. On the other hand, Omoikane-no-mikoto, who was a son of Takamimusuhi-no-mikoto was appointed to rule the nation in acting as a mediator. Apparently, we can find the division of work between religious authority and political power or of to reign and to rule.
