Sato Toguchi (佐藤 Satō) is the enemy of Miyagi and the secondary antagonist and anti-hero of the 1987 movie The Karate Kid Part II. He was portrayed by Danny Kamekona. During their childhoods, Miyagi and Sato had a strong brotherly friendship. Their friendship was so strong that Miyagi even asked his father to teach karate to him and Sato both (even though traditionally it had only been taught from father to son).
