Many judo clubs I have noticed don’t really teach concepts much or break down technique like they do in bjj

@@prandz420 Very true. You have to get lucky and get an athletic need who relishes in the details. Cheers brother!

It's not a cultural thing, it's a semantic thing. People call techniques whatever they want these days - many claiming them with names of players or even countries who's players seem to favour them. Some argue, that like language, it doesn't matter because it's natural for language to evolve, so long as everybody understands each other. But if you want to be better at judo then it's worth understanding the differences. Whoever told you that in Germany didn't know the difference between a sweep/harai (when most of the the body mass is over the other foot) and a reap/gari (when more body mass but not yet all is over the foot being attached). The 2nd, with the prop and push action is an otoshi/drop. The 3rd is as he said: gake/hook. Makikomi, is a winding movement usually with Tori's arm wrapped around and over uke's, not under. Ko uchi gake is commonly mis-named ko uchi makikomi, even by the IJF, which reflects the evolution, but as you can see here, they even name it wrongly in their video: judo.ijf.org/techniques/Ko-uchi-makikomi

Do each of those count as ippon?
