Havent seen this thread before.
I wonder how many people from the original discussion are still around and if they have changed their opinion
Judo in Japan is trained WITHOUT any weight categories, which forces the practitioners to train extensively in perfecting their timing and positioning, relying heavily on speed.
Only categories used in Japan are dan separated.
The only weight categories japanese use, are in international competitions.
The rest of the world trains with weight categories, so chances are, every player will be facing equally heavy, strong and skillful opponent. There is no dan separation in international judo competitions.
That changes the strategy and the preparation.
As in every sport- every country is trying to develop its own crops of athletes and introduce new techniques within the ruleset, expanding the diversity of the sport.
But when the same principle is applied in Judo, all of a sudden, some people think thats not pure Judo
Here is an example- in wrestling, there would be entire new chapters, known as Russian Tie, Iranian Hook, which are widely studied and used globally, but I have yet to see a Judo place, outside of East Europe, teaching Georgian Grip. It is widely seen as "dirty judo".
Why?
Maybe because in wrestling, nobody is trying to emphasize on cultural aspect, over technical skills. Nobody cares how you enter the mat or ceremonies of bowing, belt tying and etc.The only etiquette required is to be socially mannered.
While in judo, indifferent of which part of the world it is practiced, its expected from the judokas to act like japanese.
Im not saying this as a bad thing- japanese are very well mannered people.
But trying to fit a professional sport in a cultural mold is weird, unnecessary and counterproductive as sport progression, which result is, that today japanese judo got left behind the curve.
