1932 film by Teinosuke Kinugasa

The film is a lengthy work interweaving characters from different backgrounds and social strata in a narrative centered around the experiences of its heroine, Yumie Sone. Over two hours long, Seven Seas was released theatrically in two parts, with the first part entitled "Virginity Chapter" coming out in December 1931, while the second part, "Chastity Chapter," followed in March 1932. Near the beginning of the narrative, at a garden party given by the wealthy Yagibashi family in Tokyo, Yumie meets Takehiko, the Yagibashis' playboy son and the brother of Yumie's fiancé, Yuzuru. Yumie, a young middle-class woman, lives with her ailing father, a retired ministry official, an older sister, and a younger sister still a child (played by a very young Hideko Takamine). Takehiko, who has just returned from a trip to Europe, is attracted to Yumie and contrives to have her stay overnight at his family's mansion where he takes advantage of her.

The story focuses on the widower Nemoto, ostensibly a businessman, who has one son, Kanichi, the hero of the title. Nemoto remarries; his new wife is a widow with a son and daughter of her own. However, Nemoto’s business turns out to be out a shady scam, and he disappears, leaving his wife to raise the three children alone. In order to support the family, she is obliged to become a bar hostess. She conceals this shameful employment from the children, but the truth comes out years later, after her daughter is rejected by her husband’s family when they investigate her background.
