Junpei is an entomologist and a school teacher who has left Tokyo to study abroad desert plains in Hiroshi Teshigahara's 1964 Woman in the Dunes. He becomes stranded in the sand dunes and meets a woman (the woman in the dunes) in which Teshigahara's disturbing depiction of isolation unravels.
Kobo Abe, the author of the book Woman in the Dunes...in which this film is based off of, has his other works including the the title itself on Amazon (I was planning on reading the book before hand, however, I have read online that readers agree the film has done more than justice), so it's pending on my list of to-reads.
