Emperor Kōgen

Emperor Kōgen , also known as Ōyamatonekohikokunikuru no Mikoto (大倭根子日子国玖琉命) was the eighth legendary emperor of Japan, according to the traditional order of succession. Very little is known about this Emperor due to a lack of material available for further verification and study. Kōgen is known as a "legendary emperor" among historians as his actual existence is disputed. Nothing exists in the Kojiki other than his name and genealogy. Kōgen's reign allegedly began in 214 BC, he had one wife and two consorts whom he fathered six children with. After his death in 158 BC, one of his sons supposedly became Emperor Kaika.
