Seiryoku zenyo (Maximum efficiency)

Seiryoku zenyo (Maximum efficiency)

The term "Seiryoku zenyo" (Maximum efficiency) is used together with "Jita kyoei" (Mutual benefit) to express the philosophy of Kodokan Judo which was founded by Jigoro Kano.
Judo is based on the principle of a combatant using the motion and momentum of the opponent in order to apply his own power in an optimal manner, thereby generating even more power. Moreover, through the practice of attack and defense, a Judo practitioner can polish his/her own capabilities in both the dojo and in everyday life.
The concept of "Seiryoku zenyo" (Maximum efficiency) teaches that enhanced capability which Judo bestows is to be used not so much to topple and overpower an opponent, as to serve society at large.
