In Nikkatsu roman porno the question, as always, is exactly how the script will place the female lead under the control of men determined to use her. In Dan Oniroku kurokami nawa fujin, aka Black Hair Velvet Soul, it’s alcoholism and debt. A gambling and philandering husband owes a pile to a slimy financier, so he puts up as collateral the restaurant he owns with his wife. Izumi Shima plays the wife. Because the place was founded by her father and succeeded because of his sweat and struggle, as she notes in a monologue, she sees no other choice but to agree to work off the debt in an S&M club run by the financier. She goes through the usual range of indignities, but in what has to be considered a bit of a twist, she at no point likes it, nor has some inner freak unleashed, nor somehow dies by ironic means. She does her bit, the restaurant is saved, and she leaves her shitty husband. Why watch the movie? Well, because Shima is a shimmering goddess and she’s always worth watching. Sixty-six minutes including credits and you’re done. Dan Oniroku kurokami nawa fujin premiered today in 1982.
