Trivia, insights & behind the scenes
Part of Nikkatsu's 'Roman Porno' line, studio-mandated softcore that paradoxically became Japan's most artistically daring cinema of the 1970s.
Based on Jun'ichirō Tanizaki's 1956 novel 'Kagi,' which was considered unadaptable until Kumashiro cracked it by leaning into the theatricality.
