The name "kosen judo" always pops up in jujitsu vs judo discussions, as in "the omoplata wasn't invented by brazilians, kosen judo guys were already doing it in 1890". This style of judo puts the emphasis on groundwork, and has no time limit for newaza in competition. Reminds you of something ? Actually it is very similar to BJJ (or maybe I should say BJJ is similar to Kosen Judo) since they share the same roots. I had the occasion to try it for myself in Kyoto University, where the style was born and evolved, and I wasn't disapointed. The people there were much better on the ground than the average judoka, and played very active open guard games. They also had all of judo's strong points: agressive armbar atempts from all positions, good pressure and great pins, and good stand up/ground transitions (one guy was flying armbarring everybody !). Another thing that was different from traditional judo class is the large amount of sparring. After maybe 20 minutes of warm up and uchikomi, we spent about 1h30 doing randori. Overall it felt like doing BJJ with guys that are good on their feet, too (although this didn't keep them from pulling guard on me a few times...) ! I found this great because usually if you train standing up with BJJ guys they'll pull guard to drag you into their game, and if you train groundwork with judo guys they'll turtle up to stall. It's not often that you find people who blend both games seamlessly, although I think the trend in both sports is evolving in this way. So a big thank you to the Kyodai judo club for welcoming me for one class !
