Impulse Pictures will be reissuing DVD's from Japan's golden age of erotica from the early 70s to 80s from the Nikkatsu Film Studios. Nikkatsu, Japan’s oldest major movie studio, launched their “Roman Porno” erotic film line in 1971. Until 1988, the studio released more than one thousand of these films, made in a diverse range of styles and genres aimed squarely at the adult market. Impulse Pictures will be releasing over twenty-five Nikkatsu films. First up are two films: Sex Hell by director Koyu Ohara set in a women's prison and Debauchery, by director Hidehiro Ito about a prostitute immersed in a life of bondage.
