Kujō-in

Fujiwara no Teishi was born in 1131[1] to Fujiwara no Koremichi[1] and a daughter of Fujiwara no Akitaka.[1] She became the adopted daughter of the kanpaku Fujiwara no Tadamichi.[1] Like many Japanese noblewomen of the pre-modern era, the correct reading of her given name is uncertain, and the readings Teishi[1] and Shimeko are speculative on and kun readings, respectively.

In Kyūan 6 (1150) she entered the service of Emperor Konoe,[1] initially as a nyōgo[1] and later become empress (chūgū).[1] This was against the backdrop of between Tadamichi and his brother Yorinaga regarding whose daughter would be the mother of the future emperor.[1] Unfortunately, she did not provide the emperor with an heir,[1] and in Kyūju 2 (1155) she entered religious orders due to illness,[1] taking the dharma name Shōjōkan.[1] In Hōgen 1 (1156) she became Kōgō-gūshiki[1] and in Hōgen 3 (1158) Kōtaigō-gūshiki.[1] In Nin'an 3 (1168) she became a nyoin,[1] with Kujō-in as her ingō.[1]

She died in 1176.[1]
