Kajukenbo is an American hybrid martial art. The name Kajukenbo is a portmanteau of the various arts from which its style is derived: KA for Karate and Tang Soo Do Korean Karate,
JU for Judo and Jujutsu, KEN for Kenpo and BO for Western and Chinese Boxing.
It was developed in the late 1940s and founded in 1947 in the Palama Settlement of Oahu, Hawaii. The art was created through the cooperative efforts of five martial artists, each with a
different specialty: Peter Choo, Frank Ordonez, Joe Holck, Clarence Chang and Adriano Emperado.
