You can buy ring side and even though my child is of age, I would still not sit ring side with her. Yes, the rules and warnings are posted on the ticket pia site.

And based on my discussions with Jeff, he does get ring side for some guests.
OP the radios are provided at the venue. I recall they don't broadcast the whole time but the last two rounds. There is info on thr sumo Japan site.
