You look away for one second, and when you look back the referee has an arm in the air and both children are bowing. The match is over. You missed it.
What you missed was an ippon. Ippon is the full score in judo. It wins the match outright. In a kids’ competition it comes from a clean throw, where one player lands the other on their back with speed and force or a hold down. The referee will shout « ippon » and signal, the arm goes up, and the match is over.
There are three ways to score ippon:
- A perfect throw.
- Holding an opponent down for twenty seconds.
- A submission, where one player taps out (but this is only for senior judoka)
