@Red225 I disagree when a kid is reaching for the ring and shooting at point-blank range, this is definitely a disturbance in a such high tension match.
It's just as if the coach grabbed the ropes and shouted their minds out to disturb the opponent, that'd definitely be considered a foul. Here, this is her daughter and she took advantage of it.
Anyone in their right mind would be confused by a kid so near the ring which is a dangerous place for a kid to be. Audience cheers feel "far away", the ropes are the boundary of this "far away", when someone is right next to it, it feels like shouting into your zone instead of far away cheers.
Well, all that to say it would have much more satisfying for her to be beaten fair and square, but I guess the Japanese love getting hit in the balls by frustration.
