Some Judo Newaza Footage

Here is some really great footage of Kosen Judo Newaza footage. It looks pretty identical to Brazilian Jiu Jitsu although these guys are going much faster. I don't know the rules, but it would seem that they are speeding things up because there must be a time limit on how long they can be on the ground or there may be rules against limited movement on the ground. Then again, I am only speculating on this because I am not 100% familiar with the rules associated with this type of judo. It is cool to see judo folks getting back interested in groundwork though.
