Oshihime (押媛; Also known as Oshika-hime-no-mikoto (忍鹿比売命) in the Kojiki) was empress consort of Japan, and later empress dowager from 367 BC to 290 BC and then 290 BC to an unknown date, respectively.
Life
She was the daughter of Prince Amatarashikunioshihito and wife to Emperor Kōan, with whom she had two children. She was the Emperor's only wife, meaning he did not take concubines. Emperor Kōan belongs to a group of Emperors, starting with Emperor Suizei known as the Kesshi-hachidai (Eight generations lacking history). As such, there is little more than genealogy available for both him and his wife, Oshihime.
