The Nage No kata is a formal demonstration of judo techniques both left and right handed. Designed to showcase the principles of judo, generally each of the 5 sets includes three throws 1) Uke gives Tori their balance 2) Tori gets under Uki's centre of gravity 3) Tori takes the Uki's balance.
This Kata is required for the 2nd Dan grading. The video below is an excellent demonstration of the Nage No Kata.
