The Nage-no-kata were established to help understanding of the theoretical basis of judo and learn the processes involved in "Kuzushi", "Tsukuri", "Kake" in other words, how to assume the correct position for applying a throwing technique once you've broken your opponents balance and how to apply and complete a technique. The kata consist of 15 representative throwing techniques, three from each of the following five categories: Te-waza, Koshi-waza, Ashi-waza, Masutemi-waza and Yokosutemi-waza.

Each technique is executed from both sides.

The video explains the main points of the 15 techniques together with some of the common mistakes. It also includees historic footage dating back to c1930 of a demonstration of the Nage-no-kata by Shuichi Nagaoka, 10th dan, a judo master known especially for his Uki-waza. There's also a demonstration taken from the 1996 All Japan Judo Championship.

The "Katame-no-kata" were established during 1884 and 1885 in succession to the "Nage-no-kata". They consist of five representative techniques each from the Osaekomi-waza, Shime-waza and Kansetsu-waza, the aim being the mastery of the theoretical basis for executing and evading each technique.

In 1882, Master Jigoro Kano founded Kodokan Judo, establishing the Randori method based on Nage waza and Katame waza. Since then, theoretical research has lead to the establishment of numerous new techniques. Together, the Nage-no-kata and the Katame-no-kata from the Randori-no-kata, their practice helps in the understanding and mastery of the theory behind Randori techniques.

Kime-no-kata consist of twenty techniques for attack and defence. Eight are Idori techniques that are employed while seated, and twelve are Tachiai that are used when both people are standing.

Kime-no-kata were established in 1888 to help master the most effective techniques for serious competition. By studying the kata it is possible to understand and master the theoretical basis for attack and defence, thereby allowing one to move quickly and apply the most appropriate techniques to control the opponent.

Kime-no-kata include Atemi-waza, which are not used in Randori.

Regular practice is essential in order to understand the key locations and apply the atemi sharply.

Koshiki-no-kata refer to the kata of the Kito-Ryu of Jujutsu which Jigoro Kano Shihan studied before founding Kodokan Judo.

Koshiki-no-kata are based on the throwing techniques executed by armour-clad warriers on the battle field. There are fourteen Omote and seven Ura forms.

The "Itsutsu-no-kata" were established in 1887 by the founder of Kodokan Judo, Master Jigoro Kano. They form the basis of Kodokan Judo. Inspired by the forms found in nature, he strived to come up with a way of expressing those forces through judo. The result is the "Itsutsu-no-kata".

There are no names for the specific techniques, but the "Itsutsu-no-kata" comprise all the fundamental principles of Judo, applying the theoretical basis of attack and defence to natural phenomena. In that sense they can also be appreciated from an artistic point of view.

The Ju-no-kata was formulated as one of Kata of Kodokan Judo in 1887. The gentle movements are designed to teach the fundamentals of attack and defence and will make it much easier for you to learn the principals and movements of Judo. They are also an effective form of physical education. Since the forms incorporate various movements such as bending, stretching and twisting, they are very effective in conditioning the body and developing it all-round.

Another advantage of the Ju-no-kata is that they can be practiced by men and women, young and old without having to wear special dress.

This video takes you through the fifteen techniques that comprise the Ju-no-kata, pointing out some of the common mistakes that are often made. It also includes a model demonstration of each technique which will help you acquire the correct movements.
