It was already popular to do this way even before the rule change (fun fact: Chuck Norris out of all people did it to Randy Savage in a Walker Texas Ranger episode, lol), so it wasn't really an adaption of the technique especially for the rule change. I usually did kata guruma like that in randori before the change, because i like the strong pull you can create with the grip.
Uta Abe is usually more of a Newaza player, but i guess she tried to be extra fancy, since i believe this was her return after a 1 year long injury break. She hit a lot of insane stuff in the tournament. I think she won another match via Uchi Mata from a georgian grip, threw another girl with an one handed Morote Seoi Nage and won the finals after a half-nelson hammerlock turnover into Osaekomi.
It might be based on the idea of different Karate styles making their bones tougher by hitting hard surfaces. Interestingly though, olympic Judo medalist Allen Coage (aka "Bad News Allen") had a pro-wrestling feud with Yoshiaki Fujiwara in Japan about who has the most robust skull, where they would do things like that. The feud was cancelled after Fujiwara developed a (permanent) stutter from the brain damage. The stutter is the reason Karl Gotch said Fujiwara wouldn't make a good catch wrestling coach even though he has great skills.
They are the opposite of rare. The do, in fact, happen all the time. The grip limit doesn't really do anything because even with a conventional grip, you'd get a penalty for "stalling" if you hold it significantly longer than 3 seconds. The only thing those petty limits do is lead to every competitor collecting a bunch of Shidos in almost every match, which in turn doesn't really do anything except lead to the odd annoying disqualification or decision after the time limit expires. It's in essence an unnecessary rule that doesn't have any influence on how the actual match looks but just makes it that judoka keep getting Shidos even when they were clearly not trying to play dirty.
The difficulty in creating an opening even after establishing a grip as opposed to waiting for one is my bigggest problem in Tachiwaza as well, which is why i was always better at counter throws or combinations from failed attempts. For some reason though, approximately 5 years ago i started liking offensively using Tai Otoshi after like 15 years or so of not being good at it.
Something about using sumo wrestlers specifically for the example makes me chuckle. It seems so arbitrary.
Only that one specific korean Seoi Nage got banned because of the arm break risk if uke can't release his grip. Korean Seoi Nage usually goes straight backwards for Uke as well and he isn't really flipped. What Abe is doing here looks more like some insane one handed Sode Tsurikomi Goshi. But either way, there is no arm bend risk and it's not illegal.
Your instructor is correct. The do start again. My point was just that it doesn't really matter if your grip is uncoventional or conventional, as shidos, and therefore restarts, happen from conventional grips as well when the ref decides you're stalling, which often times happens after similarly short times. Therefore, there is no significant strategic disadvantage to unconventional grips and from a spectator perspective the techniques end up identical, the only difference being a bunch of resets (which, realistically, happen fairly often anyway if you consider grip breaks and resets from moving off the mat). The most interesting thing that might happen is if both competitors are one Shido away from hansoku-make and it becomes a contest of trying to not get disqualified (which is difficult, because you have to still be offensive to not get another Shido).
Knee injuries suck and i'd rather take off too long than too short after one. Fortunately, the only injuries i ever got from training Judo was a broken pinkie toe from a poorly aimed Deashi Barai and a freak accident where i completely snapped my heel vertically after getting thrown with a Kouchi Makikomi where tori somehow stepped so deep that he trapped my foot so it got twisted like a heel hook on my way down.
My girlfriends mom (from China) always told her similar stories about people from Inner Mongolia, lol
If someone made a tutorial for this throw on YouTube it would probably be widely considered a bullshit Aikido move, lol
Yeah, i can't really blame Nagasawa too much here, with the unresponsive Ref and also the ridiculously tough Brasnjovic as an opponent. I didn't expect him to be able to roll out of that Osaekomi in the first place. I see how Nagasawa won't take any risk.
This is the guy who made judo so boring, they got rid of leg attacks?
This makes me sad....Goodbye reverse seoi.
