is one of the two of Kodokan Judo. It is intended as an illustration of the various concepts of that exist in judo, and is used both as a training method and as a demonstration of understanding.
History
The nage-no-kata was developed by Jigoro Kano as a method of illustrating principles of throwing to allow students to more effectively apply them in randori. Initially the kata consisted of ten techniques. These were subsequently appended with the addition of a further five throws, including kata guruma and uki otoshi.
Description
The kata is composed of 3 techniques each from the five classifications of throw in judo:
Te-waza
Koshi-waza
Ashi-waza
Ma-sutemi-waza
Yoko-sutemi-waza
Each of these 15 techniques is performed twice in the specified order, both right and left handed. The kata is generally performed in a strictly formalised manner with clearly defined Reigi sahō.Tori and Uke approach the mat from opposite sides, with Tori on the left hand of the Joseki and Uke on the right. They bow as they step on the mat, then turn to face the Joseki and execute a ritsu rei, then turn to face each other and execute a zarei. Tori and Uke step in, left foot first, to adopt shizen hontai.
Uki otoshi
Tori approaches Uke using ayumi ashi. Tori and Uke grip using a standard right-handed sleeve-lapel grip. Uke initiates by stepping forward using tsugi ashi into migi shizentai. Tori responds by stepping backwards. Uke's balance is compromised and he attempts to regain the advantage by stepping forward again and Tori again responds by stepping backwards, further unbalancing Uke. On Uke's second attempt to regain his balance, Tori breaks rhythm, dropping to his left knee, and throws Uke to his rear, pulling with a steering motion. Tori and Uke return to their feet and repeat the technique in the opposite orientation.
Uke approaches tori, steps forward with the right foot and raises the right hand as a hammer fist to strike directly on the top of tori's head. This works better if uke uses some power and momentum to strike. Tori allows the blow to begin to fall. Tori steps around 180 degrees, grabs uke's right arm to continue to allow uke's momentum to follow forward. The forward momentum of uke's blow makes uke fall onto tori's back. At the same time tori is ready to receive uke on his back and turns his shoulders and body while maintaining grip of the arm, redirecting the forward energy of the fall to the ground. Tori and Uke return to their feet and repeat the technique in the opposite left-handed orientation.
