After graduating from the Suwa Women’s Higher School in 1922, she moved to Tokyo and began living with an anarchist named Torazo Yamamoto.

She eventually moved to Manchuria and was to give birth in a hospital in Dalian but the child lived for only twenty-four days, dying of malnutrition.

Based on this personal experience, she wrote the short story In the Charity Hospital, which established her as a writer of proletarian literature.

After the war, she became a writer of "Tenko Bungaku" ("Conversion Literature", a controversial genre dealing with the renunciation of leftist beliefs) and showed conservative, anti-communist tendencies.

During the war, after receiving help from a gambler named Seiichi Ishiguro, she became interested in the world of the yakuza and also wrote novels with a chivalrous spirit such as Kokusatsu, Chitei no Uta and Nagurareru Aitsu.
