Organisation: New Combative System and Self Defence Kajukenbo is a hybrid martial art that combines Western Boxing, Judo, Jujutsu, Kenpo Karate, Eskrima, Tang Soo Do, and Kung Fu. It was founded in 1947 in Oahu, Hawaii, at the Palama Settlement. The original purpose of the art was to deal with local criminals. The founders were Sijo ("founder")Adriano Emperado, Peter Young Yil Choo, Joe Holck, Frank Ordonez, and George Chang (sometimes mistakenly referred to as Clarence Chang) who called themselves the Black Belt Society. The founders of Kajukenbo wanted to develop an art that would "make them invincible in the most difficult streets of Hawaii".
