According to a legend, Emperor Keikō ordered 健緒組命 (Takeogumino-mikoto) to conquer enemies who were around Mt. Choraina or Chorainasan (at Mashiki ?). He succeeded and was enshrined. (Local kami or shrine called ubugamisama might be there)
According to an old document, this shrine was built in the 19th year of Emperor Kinmei (欽明天皇 Kinmei-tennō, 509–571), the 29th emperor of Japan. A governor of Higo Province, now Kumamoto, Kumamoto was on his way to Aso Shrine to pray for his country, but heavy snow prevented him from going to Aso. A boy, about 3-years of age, appeared to him and said, "Your faith in Aso God is very deep, and you are going to Aso in spite of heavy snow. You should build a shrine here, since Aso Shrine was busy with the defense of the emperor who is east, while you must defend this place against enemies west, so the name should be Kengun.[1]
