Judo was started by a Japanese educationalist, Jigoro Kano, in 1882.   Although only 22 years old, Kano saw how the skills of ju-jitsu (a Japanese martial art) could be adapted to become a safe system of physical education, with a philosophy designed to bring people together as healthy individuals both physically and psychologically.

 “Judo is the way of the highest or most efficient use of both physical and mental energy.   Through training in the attack and defence techniques of judo, the practitioner nurtures their physical and mental strength, and gradually embodies the essence of the Way of Judo.   Thus, the ultimate objective of Judo discipline is to be utilized as a means to self-perfection, and thenceforth to make a positive contribution to society.”
