Suwari Waza 座り技 is the generic name for techniques performed in the seated stance in traditional Japanese martial arts. The word "Waza" means technique. In aikido and judo, suwari waza techniques are performed by practitioners seated opposite to each other in the seiza position, the formalstyle of sitting in Japanese culture. In iaido, a single practitioner starts in many cases from suwari waza, and executes sword techniques from the seated stance, though not necessarily from a static and immobile position.
History
Suwari waza originated in the martial culture of the samurai who were expected to respond to various attackers from the seated position, with the implication that these codified techniques helped in the improvement of body stability, the maintenance of the Ki, balance, and strengthening kokyu-ho. The practice of techniques in suwari waza deprives the practitioners of the use of their legs while performing the same basic techniques they use while standing. It forces them to learn how to throw and take down an attacker using leverage, proper breathing, and hip action leading to sliding movements that compensate for the lack of leg support and strength. As the practitioner executing the move has to stay upright, suwari waza techniques differ from grappling moves in judo and forms of wrestling. Suwari waza contrasts with hanmi handachi waza over the tachi waza. These three postural forms historically bear reference to the transitional boundaries between kenjutsu and jujitsu in Japanese sword-fighting arts, depending on the initial distance between the combatants. For example, the tachi waza encounter took place when the swordsmen began standing only a pace or two apart; to advance forward from the "tachiai", the swordsmen held their weapons before them and slide or step forward, bringing their blades directly together just above the hand guards. The fluid transition from tachi waza to hanmi handachi and suwari waza emphasized the preparedness of the samurai for all occasions of combat. When perfected, suwari waza can be performed while standing, for they focus on the moving the entire body of the practitioner, and not individual limbs, through shikkō. In aikido, these techniques are preserved and practiced in the belief that the movement of hips and the body they occasion, especially the movement of the body as an entire unit, is valuable to the training of balance of the body and mind of the practitioner who learns to focus on skill than brute force. Some styles of aikido, like Kobayashi aikido, attach more emphasis to the perfecting of suwari waza techniques; others pay equal emphasis on all the three. Suwari waza techniques are also common in iaido kata forms practiced by the Musō Shinden-ryū and other koryū.
