This can apply whatever the relative values of power, thus making it possible for weaker opponents to beat significantly stronger ones. Kano realised that seiryoku zen'yō, initially conceived as a jujutsu concept, had a wider philosophical application.
Coupled with the Confucianist-influenced jita kyōei, the wider application shaped the development of judo from a bujutsu .was created as a physical, mental and moral pedagogy in Japan, in 1882, by Jigoro Kano (嘉納治五郎).
