Usually, Japanese people pray to Omoikane for success in school and exams.

He is known by other names as Tokoyo-no-Omoikane (常世思金神) in the Kojiki (古事記); Omoikane (思兼神) in the Nihon Shoki (日本書紀); Omokane (思金神, 思兼神), Tokoyo-no-Omoikane (常世思金神), Yagokoro-omoikane (八意思兼神, 八意思金神) in the Kujiki (旧事紀 or Sendai Kuji Hongi 先代旧事本紀), or Achihiko (阿智彦).

He is the son of creator deity Takamimusubi[3] (高御産巣日神) and the older brother of Takuhatachiji-hime (栲幡千千姫命, or commonly named in the Kojiki: 万幡豊秋津師比売命 Yorozuhatatoyo'akitsushi-hime), who is married to the deity Ame-no-Oshihomimi (天忍穂耳命).

In the Kojiki Tenson kōrin myth, Omoikane is one of the kami who descends to earth.

He then becomes the father of both deities, Ame-no-Uwaharu (天表春命) and Ame-no-Shitaharu (天下春命), also through this lineage becomes the patriarchal ancestor of the children of Ama-no-Koyane (天児屋命, 天児屋根命).
