Kojijū
Kojijū was a waka poet and Japanese noblewoman active in the late Heian period.
Her father was Ki no Mitsukiyo, and her mother was the poet Hanazono Sadaijinke no Kodaishin.
As a lady-in-waiting, she served the twice-empress Fujiwara no Tashi, as well as in the court of the retired Emperor Takakura. Additionally, she took part in poetry contests organized by Emperor Go-Toba. During this time, courtiers were expected to be skilled poets, and a great deal of court life involved composing and exchanging poetry, as well as participating in poetry contests. Kojijū is designated a member of the Female Thirty-Six Immortals of Poetry. She left a private collection of poems titled the Kojijū-shū.
Contemporaries noted her for her especial skill in composing poems that exactly suited the situation, particularly when writing a verse as a response to someone else's verse.
In 1179, she became a Buddhist nun.
