Aikido techniques

In more advanced training, uke may apply reversal techniques (返し技, kaeshi-waza) to regain balance and pin or throw tori.

Good ukemi involves attention to the technique, the partner and the immediate environment - it is an active rather than a passive "receiving" of Aikido.

The fall itself is part of Aikido, and is a way for the practitioner to receive, safely, what would otherwise be a devastating strike or throw (or joint lock control) and return to a standing position in one fluid movement.

The person throwing (or applying other technique) must take into account the ukemi ability of his partner, as well as the physical space: walls, weapons (wooden tantō, bokken, jō) on the tatami, and the aikido practitioners nearby.

Many of the strikes (打ち, uchi) of aikido are often said to resemble cuts from a sword or other grasped object, which indicates its origins in techniques intended for armed combat.

[citation needed] Many aikido techniques derive from Daitō-ryū Aiki-jūjutsu, but some others were invented by Morihei Ueshiba.

Different types of kokyū-nage may include: Aikido makes use of body movement (tai sabaki) to blend with uke.

[11] Additionally, an "inside" (内, uchi) technique takes place in front of uke, whereas an "outside" (外, soto) technique takes place to his side; a "front" (表, omote) technique is applied with motion to the front of uke, and a "rear" (裏, ura) version is applied with motion towards the rear of uke, usually by incorporating a turning or pivoting motion.

The target may also become unbalanced in attempting to avoid the blow, for example by jerking the head back, which may allow for an easier throw.

Most aikido strikes resemble attacks with a sword
