First technique (一教 (教), ikkyō), a control technique using one hand on the elbow and one hand near the wrist which leverages uke to the ground. This grip applies pressure into the ulnar nerve at the wrist.
Second technique (二教, nikyō) is a pronating wrist lock that torques the arm and applies painful nerve pressure. (There is an adductive wristlock or Z-lock in the ura version.)
Third technique (三教, sankyō) is a rotational wrist lock that directs upward-spiraling tension throughout the arm, elbow and shoulder.
Fourth technique (四教, yonkyō) is a shoulder control technique similar to ikkyō, but with both hands gripping the forearm. The knuckles (from the palm side) are applied to the recipient's radial nerve against the periosteum of the forearm bone.
Fifth technique (五教, gokyō) is a technique that is visually similar to ikkyō, but with an inverted grip of the wrist, medial rotation of the arm and shoulder, and downward pressure on the elbow. Common in knife and other weapon take-aways.
'Four-direction throw' (四方投げ, shihōnage) is a throw during which uke's hand is folded back past the shoulder, locking the shoulder joint.
Forearm return (小手返し, kotegaeshi) is a supinating wrist lock-throw that stretches the extensor digitorum.
Breath throw (呼吸投げ, kokyū nage) is a loosely used umbrella term for various types of mechanically unrelated techniques; kokyūnage generally do not use joint locks like other techniques.
Entering throw (入身投げ, iriminage), throws in which tori moves through the space occupied by uke. The classic form superficially resembles a "clothesline" technique.
Heaven-and-earth throw (天地投げ, tenchinage), a throw in which, beginning with ryōte-dori, moving forward, tori sweeps one hand low ("earth") and the other high ("heaven"), which unbalances uke so that he or she easily topples over.
Hip throw (腰投げ, koshinage), aikido's version of the hip throw; tori drops their hips lower than those of uke, then flips uke over the resultant fulcrum.
Figure-ten throw (十字投げ, jūjinage) or figure-ten entanglement (十字絡み, jūjigarami), a throw that locks the arms against each other (the kanji for "10" is a cross-shape: 十).
Rotary throw (回転投げ, kaiten nage) is a throw in which tori sweeps uke's arm back until it locks the shoulder joint, then uses forward pressure to throw them.
Attacks
Front-of-the-head strike (正面打ち, shōmen'uchi) is a vertical knife hand strike to the head. In training, this is usually directed at the forehead or the crown for safety, but more dangerous versions of this attack target the bridge of the nose and the maxillary sinus.
Side-of-the-head strike (横面打ち, yokomen'uchi) is a diagonal knife hand strike to the side of the head or neck.
Chest thrust (胸突き, mune-tsuki) is a punch to the torso. Specific targets include the chest, abdomen, and solar plexus, sometimes referred to as "middle-level thrust" (中段突き, chūdan-tsuki), or "direct thrust" (直突き, choku-tsuki).
Face thrust (顔面突き, ganmen-tsuki) is a punch to the face, sometimes referred to as "upper-level thrust" (上段突き, jōdan-tsuki).Single-hand grab (片手取り, katate-dori), when one hand grabs one wrist.
Both-hands grab (諸手取り, morote-dori), when both hands grab one wrist; sometimes referred to as "single hand double-handed grab" (片手両手取り, katateryōte-dori)
Both-hands grab (両手取り, ryōte-dori), when both hands grab both wrists; sometimes referred to as "double single-handed grab" (両片手取り, ryōkatate-dori).
Shoulder grab (肩取り, kata-dori) when one shoulder is grabbed.
Both-shoulders-grab (両肩取り, ryōkata-dori), when both shoulders are grabbed. It is sometimes combined with an overhead strike as shoulder grab face strike (肩取り面打ち, kata-dori men-uchi).
Chest grab (胸取り, mune-dori or muna-dori), when the lapel is grabbed; sometimes referred to as "collar grab" (襟取り, eri-dori).
