Novelist and poet. Influenced by her brother Onuki Shosen, she developed an interest in literature at an early age. She joined Shinshi-sha, hosted by Yosano Atsuko, in 1906 and published Shintai-shi poetry and waka (Japanese-style poetry). In 1910 she married the painter Okamoto Ippei. While facing issues in her married life, she participated in Seito-sha and published her first verse collection, Karoki Netami (Slight Envy), in 1912. She was hospitalized due to mental illness in 1914 and sought help from Buddhism. In 1929 her whole family travelled Europe, and when she returned to Japan in 1932 she switched to novel writing. In 1936, at the recommendation of Kawabata Yasunari she published Tsuru ha Yamiki (The Crane Sickened) in the magazine Bungakukai. Until her passing, she published aesthetic novels like Boshi Jojo (Affection between Mother and Child) (1937).
