Tenkan (literally: “convert/divert”) is the simple yet devastating trick behind most aikidō techniques. Essentially a step-pivot, tenkan efficiently and gracefully converts the opponent’s linear motion into circular motion, disrupting their balance to drive takedowns, like kote-gaeshi and irimi-nage. Tenkan can also be used to quickly get behind an opponent, to set up shihō-nage, the irimi hold, and other techniques. While tenkan is not a normal part of Goshin-Jutsu, aikijutsu techniques work best within their original framework. To tenkan:

  1. Step out into a sanchin dachi, “pre-loading” your lead leg to prevent twisting it at the end. This can be a small step.
  2. Using your lead leg as a fixed pivot, rotate your rear leg behind you, and enter a front stance. The amount you should rotate is a point of contention within the martial arts community:
    • Yoshinkan stylists believe that a tenkan should turn 95°. Since this is the minimum rotation needed to produce the desired effect, anything more is wasted motion.
    • Aikikai stylists believe that a tenkan should turn 180°. Since this is the maximum you can stably rotate, it optimizes the technique’s power.
    • Goshin-Jutsu stylists are more concerned with getting takedowns to work, since we see them as just a means to an end.

Practice tenkan back and forth, until it becomes elegant, and almost hypnotic.
