Randori rules for competition

In judo we grapple the opponent by catching the lapel and sleeve, while trying to throw the opponent down by breaking his balance. We can only use throwing techniques, as dangerous techniques such as striking or kicking are prohibited. In aikido we hold the hand, wrist, arm, limbs or body directly instead of the clothing and throw him down. On the assumption that “dangerous” attacks are delivered, body avoidance becomes necessary, so ideally techniques should be performed the moment one touches the opponent. What is suitable against dangerous attacks are the instant techniques of “atemiwaza’ and “kansetsuwaza”. Judo is mainly composed of “nagewaza” or throwing techniques, and “katamewaza’ or locking techniques. In contrast, aikido is mainly composed of “atemiwaza” or attacking techniques and “kansetsuwaza’ or joint techniques. What is common in both judo and aikido is that one tries to break the opponent’s balance thereby throwing or controlling him.
