Emperor Koan of Japan

Emperor Kōan (孝安天皇) was the sixth imperial ruler of Japan to appear on the traditional list of emperors. No firm date can be assigned to this emperor and he is regarded by historians as a "legendary emperor". This does not necessarily imply that no such person ever existed, just that there is insufficient material to assign him to a historical period.
