American Kenpo
American Kenpo (/ˈkɛnpoʊ/), also known as American Kenpo Karate or Ed Parker’s Kenpo Karate, is a hybrid martial art system developed and codified by Ed Parker in the United States during the mid-20th century. Parker organized a structured curriculum of striking techniques, forms, and self-defense methods that became widely taught through schools in the United States and internationally. The system is characterized by its emphasis on rapid striking combinations, self-defense techniques, and an evolving instructional framework.

Judo
Judo (Japanese: 柔道, Hepburn: Jūdō; lit. 'gentle way') is an unarmed modern Japanese martial art, combat sport, Olympic sport (since 1964), Paralympic sport (since 1988) and Commonwealth Games sport (since 1990). Judo is the most prominent form of Samurai throws and self-defense competed internationally. Judo was created in 1882 by Kanō Jigorō (嘉納 治五郎) as an eclectic martial art, distinguishing itself from its predecessors (primarily Tenjin Shinyo-ryu jujutsu and Kitō-ryū jujutsu) due to an emphasis on "randori" (乱取り, lit. 'free sparring') instead of kata (形, kata; pre-arranged forms) alongside its removal of striking and weapon training elements. Judo rose to prominence for its dominance over established jujutsu schools in tournaments hosted by the Tokyo Metropolitan Police Department (警視庁武術大会, Keishicho Bujutsu Taikai), resulting in its adoption as the department's primary martial art. A judo practitioner is called a "judoka" (柔道家, jūdōka), and the judo uniform is called "judogi" (柔道着, jūdōgi; "judo attire").
