柔道 

Judo

«  Traditional jū-jutsu, like many other disciplines of bu-jutsu, placed its focus strictly and exclusively on attack-defense. It is likely that many masters also gave lessons on the meaning of the Way and on moral conduct, but, fulfilling their duty as teachers, the primary goal remained that of teaching the technique. Different is the case of the Kōdōkan, where importance is given first and foremost to the acquisition of the Way and the technique is conceived solely as the means to achieve this goal. The fact is that research on jū-jutsu led me towards a Great Way that pervades the entire technical system of the art, while the effort and attempts to define the entity of the discovery clearly convinced me of the existence of the Master Way, which I defined as "the best application of mental and physical strength". » (Jigoro Kano)


"This is the difference in concept between jūjutsu and jūdō . From the technique and experiences of combat developed in the medieval period, to arrive all together to grow and progress with the best use of energy, through mutual concessions and reciprocal understanding."
This was the true evolution compared to jūjutsu which was also implemented through the formulation of the fundamental principles that regulated the new discipline:
Seiryoku-zen'y ō (精力善用) : "the best use of energy"

Jita-ky ō' ei (自他共栄): "all together for mutual well-being"
