20 Most Disturbing Japanese Horror Movies Of All Time

10. Tetsuo The Iron Man (1989)

The Plot: After a man appears to accidentally kill a "metal fetishist" (obsessed with sticking metal into his body), he finds himself slowly turning into a metal-flesh hybrid with seemingly no way to stop it. Why It's Disturbing: Despite its evidently low budget, Tetsuo has endured for over 25 years because it's so ridiculously imaginative. Much of the movie's most disturbing content comes from its frequent links between sex and violence, what with a shocking dream sequence in which the protagonist's girlfriend rapes him with a metal probe protruding from her body, and then a scene in which the man's penis transforms into a giant drill, which he then impales his girlfriend with. This is without even mentioning the return of the fetishist from the start of the film and the utterly mind-boggling ending, which only cements the movie's vividly grotesque ideas. Whether or not you subscribe to the evident homoerotic subtext, Tetsuo is an extremely discomfiting if undeniably entertaining body horror flick.
