Emperor Kōan
Emperor Kōan (孝安天皇, Kōan-tennō), also known as Yamatotarashihikokunioshihito no Mikoto (大倭帯日子国押人命) was the sixth 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. Kōan 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. Read more on Wikipedia
