Soga no Emishi (蘇我 蝦夷, 587 – July 11, 645) was a statesman of the Yamato imperial court.
His alternative names include Emishi (毛人) and Toyora no Ōomi (豊浦大臣).
Although Prince Yamashiro was another candidate, Emishi murdered Sakaibe no Marise, his uncle who nominated Oe no Ou, paving the way for his favorite.
On July 10, 645, his son Soga no Iruka was murdered by four bribed palace guards and Prince Naka no Ōe, while Empress Kōgyoku is absent from the place of the incident.
Unable to contain his despair, he burned his entire residence down and committed suicide the next day, marking the end of the Soga clan's influence on the imperial court permanently.
