小林旭
is a 1963 Japanese yakuza film directed by Seijun Suzuki and starring Akira Kobayashi, Chieko Matsubara, Daizaburo Hirata and Hiroko Itō. It was a programme picture produced by the Nikkatsu Company to fill out the second half of a double bill with Shohei Imamura's "The Insect Woman". The film was based on a novel by Taiko Hirabayashi and had been previously adapted to the screen as "Song from the Underworld" (1956) by Suzuki's mentor, Hiroshi Noguchi. The story involves Katsuta, a yakuza member who falls in love and is torn between "giri" (duty) and "ninjo" (humanity). The Kanto of the title refers to a large plain on which Tokyo is located.
