A Woman's Life A Woman's Life ("Onna no isshō", 1945), is the most famous play by Kaoru Morimoto and was the most frequently staged play during postwar Japan. Consisting of seven scenes and five acts, "A Woman's Life" tells the story of Kei as she grows from a young girl into a successful businesswoman. The play was commissioned as propaganda by the Japanese military in 1945 and was first staged later that year by the Literary Theatre (Bungakuza). Before passing away, Morimoto rewrote the first and last scenes in order for the play to remain relevant after the war.
