Creating a new Kata Part XI: The "Kata of Hip Techniques" (Koshi waza no Kata)

Purpose

Kata (form) is a prearranged set of techniques to teach, learn and practice the techniques and principles of Judo and to blend/harmonize (ri ai) them by practicing.

Koshi waza (Hip Techniques/Hip Throws) have as a principle to use your hip as a fulcrum to execute a throw. Close hip to hip contact (the hip of Tori very close below the Center of Mass of Uke), that your hip as a fulcrum can work most efficiently and not much lifting is involved. It's more like tilting/tipping.

The mechanics of Hip throws are different because of the axis, Uke is thrown:

A) Rotating Uke
- a) around your hip
- b) over your hip

B) Wheeling Uke over your hip

C) Loading Uke on your hip

D) Shifting Uke on your hip

This Kata can be taught starting with green belt. I tried to use common throws - as far as possible - in Competition Judo for demonstrating the principles and mechanics of Koshi waza also to close the gap between Kata and Shiai. Students should have a benefit practicing Kata both in understanding the principles and mechanics of Judo and success in contest.

If you like to, you can also use Koshi Uchi mata as a throw to rotate Uke over the hip of Tori and replace Tsuri goshi.
You can also change right to left handed in set one and left to right handed in set two.
