Kakimon-in

Her birth name may have been Ano Katsuko or Ano Shōshi (阿野勝子), but the sources for this name date from the seventeenth century and later. Seventeen of her poems were included in the Shin'yō Wakashū, an imperially commissioned waka anthology associated with the Southern Court, into which she was married.

Kaki Mon'in's early life and family background are uncertain. She may have been the daughter of the courtier Ano Sanetame. She went to court as the adopted daughter of Nijō Moromoto, becoming the concubine of Emperor Go-Murakami and giving birth to his son Emperor Go-Kameyama. She may have also been the mother of Emperor Chōkei. After Emperor Go-Murakami's death in 1368, she was given the title In (title), and later became a nun. She probably died at some point between 1381 and 1392.

Some Edo period genealogies give her name as "Shōshi" (勝子), but this is uncertain. Kaki Mon'in is a name she received in widowhood after 1368.

She left a private collection of waka, the Kaki Mon'in Go-shū (嘉喜門院御集), the notes (袖書 sodegaki) included in which are a valuable historical source for the accession of Emperor Chōkei. In the seventh month of 1377, at Prince Munenaga's request, she submitted the Kaki Mon'in Go-shū, from which seventeen poems were included in the Shin'yō Wakashū, an important fourteenth-century anthology compiled by the Southern Court.
