In Japan they seem a little more concerned with fighter safety and to prevent any further damage with cuts, no elbow strikes to a downed opponent (which can very very rarely knock an opponent out and is primarily used for cutting the opposing fighter)
One thing they don't do well (and that Bas Rutten and Frank Trigg criticize) is they just dab the cut and try to soak up as much blood as they can, but they don't try and close the cut with super glue or anything.
I noticed recently in K1, they seem to let Japanese fighters get cut a little more if they are in a winning position. I think it was Hiroya, who got a pretty nasty cut on his head with like 1 round to go, but he was winning....cut right over the eye, announcers were saying it was probably going to be stopped, but no, they let it go to decision so that Hiroya could beat the unknown american fighter.
Some old Pride fights they let it go, they could get pretty bloody.
Another thing I noticed is they towel off fighters a lot better in Japan, if you have been bleeding all over your opponent for half a round and you need to be repositioned, you will both get toweled off before repositioning, this would make for submissions that might actually work as opposed to slipping out of everything.
