Above, a poster for Kôkô Emanuelle: Nureta doyôbi, known in English by the interesting title High School Emanuelle: Wet Saturday. We tried but couldn’t find a copy of this one. It stars Minako Mizushima, Yûko Asuka, and Rei Okamoto, and apparently deals with a bunch of high schoolers who take kendo classes and are lusted after by teachers and the like. That isn’t much to go on, but a good image of the poster didn’t exist online before today, so at least we accomplished that much. This premiered today in 1978.
There's nothing like a sweet treat to make your day.
