IntroIf you are familiar with Japanese martial arts, particularly kendo, you may have heard the term Aiuchi. Sasama Yoshihiko, in Zusetsu Nihon Budo Jiten, defines the term as meaning when two or more people attack a single enemy at once, such as the "swarming" technique used by police to subdue an unruly prisoner. Japanese history documents instances of sannin-ai-uchi (three against one) attacks against a single samurai. The common meaning of Aiuchi is when two opponents both strike and connect at the same time. Aiuchi should be a part of your overall fighting strategy since it happens when fighting.
OutcomesIn combat, there are three possible outcomes:
- You win and the opponent dies.
- Opponent wins and you die.
- Both of you kill each other (Aiuchi).
In free-sparring, Aiuchi commonly occurs when two opponents strike each other at the same time so that their points cancel each other. It also means being willing to give up a point so you may earn more points, such as taking a one-point kick to the abdomen while delivering a two-point kick to the opponent's head.
Mutual strikes also occur when two attacks collide, such as when two punches meet head-on. If both punches were delivered correctly, their collision force will not be at its maximum since the power of both punches is being focused at the targets, not at the point where the fists collide. If one punch has more speed and power than the other, the fist may not be harmed, while the other fist may be injured.
