Kōji Wakamatsu
Another major "pink film" studio, Wakamatsu Studios, was formed by director Kōji Wakamatsu in 1965, after quitting Nikkatsu. Known as "The Pink Godfather", and called "the most important director to emerge in the pink film genre", Wakamatsu's independent productions are critically respected works usually concerned with sex and extreme violence mixed with political messages. His most controversial early films dealing with misogyny and sadism are "The Embryo Hunts In Secret" (1966), "Violated Angels" (1967), and "Go, Go Second Time Virgin" (1969).
