Kajukenbo
Hawaiian hybrid martial art created 1947 by 5 masters from Karate (KA) + Judo (JU) + Kenpo (KEN) + Boxing (BO) — one of world's first documented modern eclectic martial arts. Practical street self-defense orientation; taught internationally across all major martial arts organizations.
What is Kajukenbo?
Kajukenbo is a Hawaiian hybrid martial art founded 1947 in Honolulu by five masters from different martial arts backgrounds — the name is an acronym for KA (Karate) + JU (Judo) + KEN (Kenpo/Kempo) + BO (Boxing). The founders (Peter Choo, Frank Ordonez, Joe Holck, Adriano Emperado, and Clarence Chang) trained together in the Palama Settlement gym of Honolulu for years, deliberately synthesizing a practical hybrid system for street self-defense in rough post-WWII Honolulu neighborhoods. Kajukenbo is one of the world's first documented MODERN ECLECTIC MARTIAL ARTS — predating Bruce Lee's Jeet Kune Do philosophy of style-blending. Now taught internationally with major branches: Emperado method (traditional), Wun Hop Kuen Do (Chinese-influenced), Ch'uan Fa method, Tum Pai. Practical self-defense orientation, hard-contact training, and pragmatic (not sport-oriented) focus distinguishes Kajukenbo from purer style traditions.

Frequently asked
How is Kajukenbo different from MMA?+
Both blend styles, but MMA is competition-focused sport (UFC etc.) with rulesets; Kajukenbo is self-defense martial art tradition without primary competition orientation. Kajukenbo predates MMA by 40+ years as documented style-blending. Modern MMA fighters may cross-train Kajukenbo elements.
Is Kajukenbo effective for real self-defense?+
Yes — founded specifically for practical Honolulu street self-defense post-WWII. Hard-contact training tradition + eclectic technique base makes Kajukenbo more practical than many pure-style traditions. Modern effectiveness depends on training quality + practitioner.
