Koreyoshi Kurahara - Kaitei kara kita onna AKA The Woman from the Sea (1959)

Quote:
“A curious hybrid of taiyôzoku-eiga (“Sun Tribe”) and “girl-diver” genres, Koreyoshi Kurahara’s mermaid tale plays out like no other midnight movie in history – sinister, sensual and ethereal, it unfurls almost in slow motion. Hisako Tsukuba plays a voluptuous, gloomy beauty who likes to feast on fish guts.”
