Director and screenwriter, Shunya Itō is a Japanese film director known for starting the Sasori / Female Prisoner Scorpion series of 1970s exploitation films starring Meiko Kaji.

He won Picture of the Year at the Japanese Academy Awards in 1985 with his film Gray Sunset,[2] a story of a man suffering from Alzheimer’s disease. This thus became Japan’s entry for the Academy Award for Best Foreign Language Film instead of Akira Kurosawa’s Ran, which caused a slight uproar in Western media as many critics thought Ran had a real chance of winning whereas Gray Sunset was not even shortlisted.
