The Insect Woman (1963)

Amorality in Japan. Tome is born into poverty in rural Japan, in the late 1910s. Chuji, her father, dotes on her; her mother is less faithful. Tome becomes a neighbor's mistress, works at his mill as World War II rages, and has a daughter. After an affair with a mill supervisor, Tome goes to Tokyo to seek her fortune. She leaves the child, Nobuko, in Chuji's care. Tome's a maid at a brothel, learns trade from the madam, enjoys the protection of a businessman whose mistress she becomes, and is soon herself the boss. As Chuji ages and Nobuko grows up with her own ideas, can Tome's self-preserving schemes provide continued comfort? Or will the mice scamper over her?
