Aikido techniques are frequently referred to as waza 技 . Aikido
Aikido
is a Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs.

, or shite , (depending on aikido style) also referred to as ( nage (when applying a throwing technique), who neutralises this attack with an aikido technique.

Both halves of the technique, that of uke and that of tori, are considered essential to aikido training. Both are studying aikido principles of blending and adaptation. Tori learns to blend with and control attacking energy, while uke learns to become calm and flexible in the disadvantageous, off-balance positions in which tori places him. This "receiving" of the technique is called ukemi. Uke continuously seeks to regain balance and cover vulnerabilities (e.g., an exposed side), while tori uses position and timing to keep uke off-balance

 and vulnerable. In more advanced training, uke may apply to regain balance and pin or throw tori.

refers to the act of receiving a technique. 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 and return to a standing position in one fluid movement. The person throwing must take into account the ukemi ability of his partner, as well as the physical space: walls, weapons (wooden tantō

Uke must attack with a strength and speed appropriate to the aikido skill level of the tori; in the case of beginner women and children, this means an attack of far less severity than would be encountered in a real-life self-defense situation.

Techniques

When all attacks are considered, aikido has over 10,000 nameable techniques. Many aikido techniques derive from Daitō-ryū Aiki-jūjutsu, but some others were invented by Morihei Ueshiba

Implementations

Aikido makes use of body movement (tai sabaki

) to blend with uke. For example, an "entering" (irimi

) technique consists of movements inward towards uke, while a technique uses a pivoting motion.
Additionally, an technique takes place in front of uke, whereas an technique takes place to his side; a technique is applied with motion to the front of uke, and a version is applied with motion towards the rear of uke, usually by incorporating a turning or pivoting motion. Finally, most techniques can be performed while in a seated posture (seiza
Seiza
Seiza is the Japanese term for the traditional formal way of sitting in Japan.- Form :To sit seiza-style, one first kneels on the floor, folding one's legs underneath one's thighs, while resting the buttocks on the heels...

). Techniques where both uke and nage are sitting are called suwari-waza, and techniques performed with uke standing and nage sitting are called hanmi handachi.

Thus, from fewer than twenty basic techniques, there are thousands of possible implementations. For instance, ikkyō can be applied to an opponent moving forward with a strike (perhaps with an ura type of movement to redirect the incoming force), or to an opponent who has already struck and is now moving back to reestablish distance (perhaps an omote-waza version). Specific aikido kata are typically referred to with the formula "attack-technique(-modifier)". For instance, katate-dori ikkyō refers to any ikkyō technique executed when uke is holding one wrist. This could be further specified as katate-dori ikkyō omote, referring to any forward-moving ikkyō technique from that grab.

A strike, whether or not it is blocked, can startle the target and break his or her concentration. 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.
Many sayings about atemi are attributed to Morihei Ueshiba
