This film's director Hiroshi Teshigahara made one of my favorite movies of all time, Woman In the Dunes, and he didn't disappoint with this one. This and Woman are two of four movies he collaborated with the author/screenwriter Kobo Abe and brilliant composer Toru Takemitsu.
What begins as an interesting look on worker's rights turns into a dramatic, not horrific, telling of a ghost story.
All while maintaining its beauty as a simple, daring work of art. Undeniably an art-film, despite how sucky that term sounds.
Teshigahara is certainly the closest thing Japan could ever have to their own Hitchcock.
