"Use only that which works and take it from any place you can find it."
Kudo is a Budo mixed martial art sport comprising of full contact punches, kicks, throws/takedowns, and submission techniques.
Kudo has its origins in Kakuto Karate (Combat Karate) and Judo, but It is not just a mixed fighting system with an emphasis on the competition side. It is a life-long pursuit, for youth education, self-defense and health maintenance for adults.
Along with these elements, it stresses the "Reigi" or respect and etiquette in its tradition. In this sense it is a "Modern Budo" that has already spread to more then 80 countries around the world.
