Aikido
Tenkan is a very common technique in aikido. Strategically, tenkan is most often used to place nage back-to-back with uke. A few techniques that commonly begin by executing tenkan include: shōmen'uchi - kaitennage; katate-dori - shihōnage; and morote-dori - kokyūnage.
Some styles of aikido practice six basic ashi sabaki (stepping/footwork) techniques, of which tenkan is one.
Those six basic stepping techniques are:
- Tsugi-ashi (shuffle step)
- Ayumi-ashi (crossing step)
- Kaiten (hip shift to avoid attack)
- Tenshin (step and pivot to avoid attack)
- Tenkan (180 degree pivot to avoid attack)
- Ude-furi (spin step)
