Well for those who remember me from posts along time ago, (college, National Guard, teaching, Judo, Aikido, and work kept me away from here), know that I like the self defense aspect of Judo more than the shiai aspect. Funny how injuries make you see that.lol. I recently tried a form of Uki-Tori in which more self defense techniques were utilized. this was done by asking the uki to throw slow but honest attacks at tori and it was tori's job to defend his or herself from the attack. The results it produced were amazing. while they knew various self defense techniques, (they are required for advancement in their Dojo) their timing was totally off and they couldn't get out of kata learning mode. (knowing what technique was coming when it was coming and where it was coming from.). So afterwards i sat down with them and discussed this and they came to the same conclusion. Kata is important very important especially in teaching the techniques to judoka, but like shiai you can become trapped in its framework and actually start hurting your Judo progression. So now when we have a self defense night or day.lol We end the class by doing an hour or so of self defense randori.
Don't know if this helps or not but seemed like a good place to explain this.
