Scoring ippon

When ippon is scored, the fight is over. The referee annouces ippon when in his opinion an applied technique corresponds to the following criteria :

(d) when a contestant is incapacitated by a shime waza or kansetsu waza

Should one contestant gain a second waza ari in the contest the referee annouces waza ari awasete ippon

The referee annouces sogo gachi (compound win) when one contestant has gained a waza ari and his opponent subsequently receives a penalty of keikoku

Penalties

There are four levels of penalties in judo :

- shido or note

- chui or caution

- keikoku or warning

- hansoku make or disqualification

Penalties are not cumulative. Each penalty must be awarded at its own value. Whenever a contestant has already been penalised, any succeeding penalties for that contestant must always be awarded, at least, in the next higher value than his existing penalty.
