The idea of combining the best aspects of different martial arts, boxing and wrestling together is not a new one. Kempo masters were already doing this in Japan in the early years of the Twentieth Century.
Kempo masters collaborated to create a great variety of highly effective martial arts methods that are still used today by the Japanese military, special forces and police, as well as parts of the Japanese underworld.
Kempo also influenced the development of modern martial arts movements and sports such as Nippon Kempo, Krav Maga, Hawaiian Kempo, Shin Kakutojutsu, Shooto, K-1 and MMA.
Kempo is unusual among modern martial arts in that it places a heavy emphasis on weapons training. The idea is that a practitioner must be highly skilled in the use of a weapon in order to be able to defend himself against it.
