Princess Kaoruko

Princess Kaoruko, also known as Saiin-no Kōgō, was an empress consort of her cousin Emperor Go-Sanjō of Japan.

Biography

While a young child, she served as a Saiin from 1032 until 1036. She was a daughter of Emperor Go-Ichijō, and as such, marriage to her represented a means to lessen some of the influence of the powerful Fujiwara family. She married her cousin the future emperor in 1051. In 1068, her husband became emperor, and she was appointed empress.
Her husband had three consorts: Kaoruko, Minamoto Motoko, and Fujiwara Shigeko. The emperor hoped that Kaoruko would bear an heir, and thus allow him to pass the throne to a non-Fujiwara son. She had no children, however, and after the death of her husband, she became a Buddhist nun under the name Saiin-no Kōgō.
