Well, that was insanely disgusting and horrible. Here's a German one-liner that describes it: "Japanischer 69er Torture Episodenfilm".
It's a depravity-fest, set in the Edo era (1603-1868). Teruo Ishii has three stories for us, all vying hard for the title of "most appalling thing you've ever seen". (The previous year, he'd made Shogun's Joy of Torture.) There's lots of nudity, but it's the opposite of "sexy".
STORY #1: NICE GIRL GETS SOLD INTO PROSTITUTION
Oito and her sister Kinu owe money to local criminals, who suggest that they repay the debt with their bodies. Naturally the girls are horrified, but the scene turns violent and things are looking bad until a handsome swordsman, Hanji, saves them. Later, unfortunately, Hanji claims to be in debt himself. What can Oito do to help? Well, Hanji has a friend who might be able to find Oiro a well-paid job...
Reasons why this story is shocking include:
(a) Oito's so nice and she keeps believing in Hanji long after the audience have decided that he's scum who needs hanging from the nearest tree. She's also stupid, mind you. Even when she's sobbing and in despair after her first day of prostitution, Hanji can talk her round with lines like this: "I didn't fall in love with your body. I fell in love with your beautiful heart." However she's so, so stupid and pure that it's like watching slow-motion child abuse.
"I'm carrying your baby." (How does she know it's his?) "A woman can tell." (No, I think you're in happy fairy land there.)
(b) After the worst has happened (involving beatings, torture, death, betrayal and a do-it-yourself abortion with a big rock), for the first time Hanji feels remorse. "What can I do to earn your forgiveness?!?" Words fail me.
(c) The following may or may not have been intentionally offensive from the filmmakers. This is another "women enjoy being raped" Japanese film. Hanji has sex with Oito against her will, as she's crying and saying "no". Next scene: she's in love with him.
Jesus wept. It's stylish, mind you. The film's capable of becoming abstract art. Also, in fairness, it's not particularly gory, while it might be a sign of sickness to find this film's nudity sexy. It's still an extremely rough watch, though.
STORY #2: STOCKHOLM SYNDROME BUT SO MUCH WORSE
Two dwarves attack, gag and rape a woman who then starts laughing and beating them. Her servant hired them to attack her, on his mistress's orders. As he explains to a doctor who guest-stars in all three of these stories...
"Being raped by men with abnormal bodies greatly arouses her."
It ends in grand guignol and scary insanity. It even manages to be offensive accidentally when a character says "kichigai", which today has become explosively unsayable and will get bleeped on television.
STORY #3: THE SADISTIC LORD
After all that, I'd been assuming that the third story would be an anticlimax. You couldn't trump the film so far. Little did I know. Welcome to the court of a lord whose idea of fun includes:
(a) lassoing a woman in the countryside and dragging her to death behind his horse
(b) unleashing a herd of bulls with burning horns upon a group of dancers in red clothes. "You'll live if you strip!" he tells them, then starts firing arrows into the melee.
(c) stripping a woman called Mitsu with sword blows, then binding her with rope, hanging her upside-down and sticking arrows in her. It's gross. The victim's enjoying it. "More, my lord. Please torture me more cruelly."
It then goes batshit crazy. Yes, more so. It's loonier than Story #2, which had already been out of its gourd. A woman uses a dog for sexual pleasure and it spirals down from there. It also has the attempted execution of a woman with gold paint, suggesting that someone's been watching Goldfinger. (Note: this wouldn't work.)
I don't think there's really anything I can say here. Observing that this film is offensive would be like hammering nails into my knees and then saying "ouch". I chose to watch the film. Nobody made me. Women get killed a lot, usually after gratuitous suffering, blood and/or torture, but then again you wouldn't want to be a man in this movie either. Watch this film if you're into sadism and sexual deviancy so weird that you'd probably have to google the words for them.
