Gate of Flesh

Gate of Flesh is a 1964 Japanese film based on a novel by Taijiro Tamura and directed by Seijun Suzuki. The first of Suzuki's "flesh trilogy", the series is considered the "crowning achievement" of his period working at the production house Nikkatsu. The film is viewed as a direct and allegorical critique of Japan's Occupation and subsequent development, which rather than breaking with the country's pre-war militaristic, authoritarian social structures only sees their reconstitution in the post-war period.
