From Impulse Pictures / Synapse Films
All the films are presented in their original aspect ratios, in good quality, with Japanese audio and newly translated English subtitles. Extras consists of only the original theatrical trailer (if even that…) and liner notes from Jasper Sharp. So far every film, except True Story Of A Woman In Jail: Sex Hell, in this collection has also previously had a Japanese release but those were all without English subtitles.
The covers below will take you to the pages about the film in question, or you can check all* the DVDs at Amazon.com or Synapse Films.
*Amazon doesn’t list Eros School: Feels So Good (too controversial title for some of their customers?).
There is also one Blu-Ray available and a trailer collection DVD with over 30 trailers + a bonus short film Ryoko’s Lesbian Flight.
Back in 2004 (so they are not part of the The Nikkatsu Erotic Films Collection) Synapse Films also released the films Entrails of a Virgin (処女のはらわた) & Entrails Of A Beautiful Woman (美女のはらわた) on DVD.
