judo standing fight

In the standing phase, which has primacy according to the contest rules, the opponents attempt to throw each other. Although standing joint-lock and choke/strangulation submission techniques are legal in the standing phase, they are quite rare due to the fact that they are much harder to apply standing than throws are. Some jūdōka, however, are very skilled in combining takedowns with submissions, where a submission technique is begun standing and finished on the ground.

Strikes (i.e. punches, kicks, etc...) are not allowed due to their certainty of injury, but an athlete is supposed to "take them into consideration" while training by, for example, not fighting in a bent-over position for long, since this position is vulnerable to knee-strikes and other striking attacks.

The main purpose of the throwing techniques (nage waza) is to take an opponent who is standing on his feet, mobile and dangerous, down onto his back where he cannot move as effectively. Thus, the main reason for throwing the opponent is to control the opponent and to put oneself in a dominant position. In this way the practitioner has more potential to render a decisive outcome. Another reason to throw the opponent is to shock his body through smashing him forcefully onto the ground. If an opponent executes a powerful yet fully controlled throw, he can win a match outright (by ippon) on the basis that he has displayed sufficient superiority. A lower score is given for lesser throws. A score for a throw is only given when executed starting from a standing position.

In keeping with Kano's emphasis on scientific analysis and reasoning, the standard Kodokan judo pedagogy dictates that any throwing technique is theoretically a four phased event: off-balancing (kuzushi); body positioning (作り, tsukuri); execution (掛け, kake); and finally the finish or coup de grâce (極め, kime). Each phase follows the previous one with great rapidity - ideally they happen almost simultaneously.
