What is "chujo-hime"

(also written Chūjōhime or Chūjō Hime) (753?–781?) was by most accounts a daughter of the court noble Fujiwara no Toyonari who escaped persecution at the hands of her stepmother by becoming a nun at the Taima-dera in Nara. There she took on the name Zenshin-ni or the Dharma name Honyo (法如). She has become a folk heroine, the subject of numerous Japanese folktales which celebrate her filial piety. She is sometimes called the Japanese Cinderella.
