Kanō Jigorō founded Kodokan judo in 1882. It was derived from jūjutsu. Kanō believed that the ultimate purpose of judo practice was to perfect the self also for the benefit of others. He devised the concepts of seiryoku zenyō and jita kyōei (maximum efficiency and mutual prosperity), which are the idealistic foundation stones of judo training. (It is a paradoxical distraction unfortunate that in Olympic judo the focus on moral development has received less attention than its role as a competitive sport).
