"Roman Porno from 1985. A young teacher heads off to teach fencing in a school in the countryside."

This is a Japanese Cat III movie which contains lots of frontal nudity but it is not vulgar as other Cat III movies are...

The fencing teacher Noriko Saotome (Ran Masak), is invited to teach fencing at a remote mountain school, not realizing that her so-called friend, Saeko Okazaki (Izumi Shima) has a personal reason and ulterior motive in recommending her for the open position...

It turns out from even before the two ladies reach the school, that the male students in the school (young students (and later, the faculty alike) are misogynist. Also, an incident shows that the female students are very tolerant of this mindset.

First, mistreatment by students leads the main female lead into a world of sex, submission and perversion by all men, including the school's principal.

Although many reviewers believe this is not worth watching, I totally disagree. This is a great film featuring nudity but no raunchy sex scenes!

The cinematography is as good as any other regular film for its time, both the inside and outside settings. The music which assists in setting mood and segues in the movie is excellent and the actors/actresses play their roles convincingly and add to the overall atmosphere of this under-rated movie.

From my readings on the Internet, the actress Ran Masak maintained a special working relationship with director Masahito Segawa during their professional career years; I would recommend trying all the movies in which they collaborated.
