Judo: Randori-no-kata

Randori-no-kata is a comprehensive work on the basic judo kata, nage-no-kata and katame-no-kata. Jigoro Kano designed these kata, collectively known as randori-no-kata, to develop judokas' competitive skills and deepen their understanding of judo. Nage-no-kata teaches the fundamental principles of throwing techniques, while katame-no-kata focuses on control techniques.
This book presents detailed execution guidelines based on the latest models from Kodokan and the IJF. Photographs and illustrations help readers grasp the correct execution of each technique. In addition, the book explores the principles behind the techniques and provides practical tips for training and teaching.
Randori-no-kata serves as both a guide and a valuable resource for beginners learning judo kata for the first time, as well as for experienced judo instructors and kata competitors.

I taught the principles (of judo), not the application of the principles... If something goes wrong with the application (technique), be it technical or mental, then return to the basic principles and test how closely they are reflected in the application.

- Jigoro Kano, 1934, as quoted in Judo Kata: Practice, Competition, Purpose
