Hisayasu Satō

Hisayasu Satō (佐藤 寿保, Satō Hisayasu, born 15 August 1959 in Shizuoka City, Japan) is a Japanese exploitation film director. He has worked prolifically in the genre of pinku eiga films, which refers to Japanese films that prominently feature nudity or sexual content. His best-known works are the 1992 pink film The Bedroom and the 1996 V-Cinema splatter film Splatter: Naked Blood. He is known for his "sledgehammer" filmmaking style, and using his exploitation career to tackle serious subjects like obsession, alienation, perversion and voyeurism.

He has been likened to Canadian director David Cronenberg due to his penchant for body horror as well as dark eroticism. Along with fellow directors Kazuhiro Sano, Toshiki Satō and Takahisa Zeze, he is known as one of the "Four Heavenly Kings of Pink" (ピンク四天王, pinku shitenno).
