The ‘shido’ is called when a rule violation occurs during a judo contest. A shido is issued for minor violations such as excessive passivity, using a manoeuvre that hinders the development of a technique, using a technique that poses a risk injury to the opponent.
Shido on the score board will be displayed with a yellow card. A judoka can only be penalised a maximum of three times during a contest. The third shido will be announced as ‘hansoku-make’ which is direct disqualification.
