Those events are massive. Usually police force is involved to steer the crowds. Streets are closed. Disruption everywhere. But, oh boy, it is so worth to sacrifice convenience to see the show. I've had occasion to see three and that was fantastic experience. Show in Nagaoka, in Niigata prefecture was the biggest and the most colorful I've seen in my life (not that I've seen many, still) and the execution, sync with the music, was flawless. I must thank my Japanese friends who booked the trip for us all. Otherwise I would miss it for sure. The two others not worse a bit. One next to Sumida river - the biggest one in Tokyo - and the other in Tokyo too, next to Futakotamagawa station. Both spectacular.
One other aspect of any bigger events that always amazes me is how safe and organized they are. Everyone is drinking hard during many of those and still no one argues, no one is aggressive and no one steals. That's a digression, though.
Sounds a bit like a lost art, but I guess parade floats are similar.
