Roy Kenneth Kamen, known professionally as Roy Kamen, began studying Isshinryu Karate in 1965 under his brother, Robert Mark Kamen, creator and writer of The Karate Kid. He later studied Shotokan under Toyotaro Miyazaki and, in 1980, earned his second-degree black belt in traditional Okinawan Goju-ryu karate from Master Seikichi Toguchi, a first-generation student of Goju-Ryu founder Chojun Miyagi and Master Seiko Higa.
Kow Loon (Kayo) Ong awarded Roy his eighth degree in 2017. In 2024, Roy was awarded ninth-degree black belt certification by Tetsuhiro Hokama, a tenth-degree Goju-ryu karate master and curator of the Karate Museum in Naha, Okinawa.
Roy is chief instructor of One World Dojo and teaches karate at Active Studios NYC and in New York City public-school after-school programs. He is the author of Karate: Beneath the Surface: Emotional and Spiritual Content of Goju-ryu Kata. Drawing on more than six decades of practice, he explores the questions that arise as a martial artist’s experience, circumstances and reasons for training change. His book approaches familiar kata as connected stepping stones into deeper inquiry.
Outside the dojo, Roy owned and operated Kamen Entertainment Group, Inc., producing more than 40,000 radio, television, film, fitness, music and live-theater projects that earned over 140 industry awards.
