Plot synopsis: Inoue was something of a rarity in the sense, that he was a Shochiku house director who seems to have worked mostly in period films, often with big stars like Hasegawa or Bando. "Sumidagawa", named after the river that runs through Tokyo, is also a period film, but thematically a modern one. All the themes that you associate with the normal Shochiku women's films set in the present day are in this film, just in a different context: love, the planning of a marriage, career, family relations and societal melancholy. There is no action or swordplay.
