Seifuku shojo: Za ejiki

Hisayasu Sato is a Japanese exploitation film director. He has worked prolifically in the pinku eiga genre. He is known for his "sledgehammer" filmmaking style, and using his exploitation career to tackle serious subjects like obsession, alienation, perversion and voyeurism. He is famous for his "guerilla shooting technique" in which his actors appear on location in public and incorporate unknowing bystanders into the film. Hisayasu Sato’s often violent but highly visual works utilised a multitude of multimedia devices to reflect upon issues such as the power of the gaze, the dehumanising effects of technology and the loss of the individual’s sense of “self” that accompanied Japan’s period of economic boom in the late 80s.
