The Katame Waza Ura no Kata is the method of counter techniques in Ne Waza created by the master Kazuo Ito (9th Dan) in the 1960s thanks to the teachings of his master; the great Kyuzo Mifune (10th Dan). From the point of view of combat on the ground, this method effectively instructs in a multitude of aspects and principles. The kata was designed to counterattack the techniques of Katame no Kata, using its structure, order in the execution of the techniques and protocol. But the Katame Waza ura no Kata has an even greater scope and can be practiced in a more open and flexible way, providing the student with a great variety of ways to defend himself against various attacks of Joint Lock, immobilization and strangulation. Once again, the Kano Ryu International School together with the International Traditional Kodokan Judo (ITKJ) rescue ancient kata that should never have died out. The Kodokan Judo created by Jigoro Kano and protected and preserved by his main students must remain alive and present at any time for the benefit of all humanity.
