As a member of the Philadelphia Judo Club, one of the things we are required to do to get through the ranks of brown and black belts is kata. For first degree black belt, we have to do Nage no kata both as uke and tori, each of the fifteen throws down on both left and right sides.
While my goals in judo at this time are strictly competition oriented, I find that learning kata has been useful in becoming a better uke (understanding the dynamics of being thrown). Also, in my limited experience with it, I have learned in just a few classes how to be more patient and break down each throw carefully to achieve proper form.
Here’s a video of two of our judoka performing Nage no kata:
