 In 1935 she was arrested for anti-war activism and spent two months in jail.This experience is described in part in her semi-autobiographical novel, "Kurenai" (Crimson), which was serialized from 1936–38 and focuses on the troubled married life of a woman writer much like Sata.Sata's strong opinions were often at odds with the official Communist Party platform; juggling the many demands she faced as a writer, activist, mother and wife, she eventually became estranged from her husband, whom she finally divorced in 1945.
