Novelist. While attending the Tochigi Girl’s Higher School, she published tanka poetry works in girl’s magazines. After she graduated from school, she moved to Tokyo and in 1917 started to write the series Hana Monogatari (Flower Tales) (1924) in the magazine Shojo Gaho, which gave her recognition as a writer of books for children and girls. In 1919 Chi no Hatemade (To the Ends of the Earth) won a competition held by Osaka Mainichi Shimbun, and Otto no Teiso (A Husband's Chastity) became a hit amongst women, which made her one of the most commercially successful novelists. In the post-war period she published Onibi (Demon Fire) in 1952 and Toki no Koe (Battle Cry) in 1965. In her later years she completed the historical novel masterpiece Tokugawa no Fujin Tachi (Tokugawa Women) in 1966.
