Ōtomo no Koteko
, also known as , was empress-consort of Emperor Sushun, the 32nd Emperor of Japan who reigned from 587 to 592. Koteko was the mother of Sushun's only recorded son (Prince Hachiko) and daughter. According to the "Nihongi", Koteko participated indirectly in her husband's assassination. The details of this historical narrative are incoherent without more specific information. Historians tend to question or to discredit this alleged incident in the traditional narrative because it seems incongruent with what else is known about the Imperial Court in the year of Sushun's death.
