The martial arts colored belt ranking system was originated by Dr. Jigoro Kano, who was Japanese and known as the "Founder of Modern Judo", who first devised many of the concepts that are the foundation of Modern martial arts. Dr. Kano devised the colored belt system as a visible sign of a student’s progress, awarding the first “black belts” in the 1880's. Gichin Funakoshi, who was Okinawan and the founder of Shotokan Karate and often referred to as the "Founder of Modern Karate" adopted the belt ranking system and other organizational and philosophical concepts from Dr. Kano, who was both his contemporary and friend.
