Pinku from 1975. This is another softcore pinku eiga melodrama dealing with the proverbial “Dutch wife” (a Japanese slang term for love dolls), given an unusually clever treatment by Nikkatsu’s leading director, Chusei Sone. Nobutaka Masutomi stars as a doctor who develops a robot love doll to keep a team of Antarctic researchers company, but is displeased with the result despite the product’s success. His desire to create a more realistic doll leads the doctor to model one after an attractive college student (Maya Hiromi). Naomi Oka co-stars, and the screenplay was by Atsushi Yamatoya, who had directed the subgenre’s most notorious cult film, Koya No Dacchi Waifu, in 1967.
