'Black Hair, Velvet Soul' (1982) aka Dan Oniroku kurokami nawa fujin– Mamoru Watanabe.

 Mamoru Watanabe's engrossingly erotic crime drama concerns a degenerate husband's escalating gambling debt that fatefully drags his beautiful, virtuous wife into the vile clutches of an impotent Yakuza sadist! There's a palpable melancholy to the wholly innocent wife's (Izumi Shima) plight that I found genuinely moving. Engagingly written by Roman Porno icon, Oniroku Dan, his sleazy, tantalizingly lurid S & M tale being infused with moments of dark poetry caught me somewhat unawares. Smartly directed by Watanabe, his fine cast brings an unexpected pathos to the sordidly Rope bound Yakuza shenanigans, with the elegant, Izumi Shima being especially poignant in her demanding role as the genteel, greatly suffering, self-sacrificing wife.
