This work makes a profound and unprecedented study of 6 ancient kata that are practically in disuse, some of these katas were created directly by Jigoro Kano and others by first generation students or by the direction of the Kodokan. They are therefore part of the more traditional judo and deserve to occupy a place in the regular practice of judo and jujutsu. These 6 katas have a unique beauty, worthy of being preserved and spread so that they can reach new generations of Instructors and teachers, and thus return to Judo all that has been lost along the way and honorably honor the memory of the master Jigoro Kano.
