Oh, I'll happiliy criticise them... not for the sparring (although their methods do encourage bad habits, and takes them from the reality they think it brings them closer to...), as that's not where the real issues are.
It's the "swordsmanship" in the rest of the clip. The cuts are stilted and pulled, the grips are too tight, there is little in the way of tenouchi that I saw, movements are done for effect without the reason, they appear to be unable to move outside of their own heads, and they would not have much chance against an actual swordsman. That's just the beginning, though.
As for the "Toyama" clip, one thing to realise is that the people there are not actually Toyama Ryu practitioners, but people who came to a Toyama event to put on a demonstration. So it's still not Kenjutsu, gendai or koryu. They have been discussed here before, but the main things I noted last time are a prevalence of kendo-style hitting, rather than committed cuts, a lot of little "tapping" actions, and a few other things that made most of what they did rather ineffective, and again removed from the reality it was meant to get closer to. Unfortunately, that is the effect of "sparring" in sword arts.
If you are sparring in a sword art then you are actually removing it from reality. The reason is simple: If you are acting and moving realistically, then you are aiming for disabling or killing cuts every time. And if you do that, the way to ensure that that happens is to ensure that the reciever is stopped by the blows you strike, which means actually hitting in a way that achieves that result (which, if items like bokken are used means that a disabling cut, such as a cut to the inside of the wrists, won't be present, so a blade would be needed... I think we can see where that is going). If strikes are used that don't finish the encounter, or if finishing strikes don't actually finish the encounter (ie they are well struck, on target etc, but the opponent is not physically stopped, the way that a solid strike to the top of the head would, as control is being used) then the encounter will continue. That will lead to the employment of faster strikes as both try to get in first, not worrying about the fact that a mistake means death or dismemberment, which means less effective cuts, strikes instead of cuts, and so on.
So either it's fairly realistic, and people go to hospital, or it's not realistic, and that defeats the purpose of most people in engaging in such practices.
