Kanō Jigorō believed Jitsu has an important cultural legacy but it must change its purpose. It must be taught for educational, physical and moral improvement. He opens its Ju-Jutsu school, the Kodokan Judô in 1882.
-To improve the reputation of Japanese martial arts, Kodokan creates, Code of Ethics (such as the prohibition of fighting for money) and a teaching curriculum. Kano’s idea is that his method is not just to train to fight, but a form of personal evolution. That is why he uses the word “do”.
-Kano also emphasizes a training method based on randori (sparring).
-Many Ju-Jutsu schools based most of their training on the practice of combined forms (Kata), in which both students cooperated to do the techniques.
Kata were a way of training techniques that were too dangerous to be used in free sparring.
