Sex Family (1971)
Original title: 性家族
Sex Family is a 1971 Japanese-language drama movie directed by Kōji Wakamatsu, with a running time of 1h 13m. It stars Tamaki Katori, Miki Hayashi and Yôko Mutô.
A critique of the Japanese family, seen here as militaristic, absurdly incestuous and patriarchal with the father dominating his family sexually and violently. Nihilistic destruction by the young ones seems to be the only way out.
