Tai sabaki(体捌き?) is a term from Japanesemartial arts and which relates to 'whole body movement', or repositioning. It can be translated as body-management. It is a term used widely in and very important in kendo, jujutsu, aikido, judo, karate and ninjutsu. Tai sabaki is usually used to avoid an attack, such that the receiver of the attack ends up in an advantageous position and it is often wrongly referred to as evasion.
Tai sabaki is related to ashi sabaki (footwork) and te sabaki (handwork).
The origins of Tai-sabaki can be transliterated from the sumo wrestler way of honoring the top ranks of grand champions "津名学士気"; which translates into "Bachelor Flow of Grand Champions" when taking into account the yokozuna ranking system for sumo wrestlers.
All three katas were created on the basis of the Tai sabaki movements and the circular motions of aikido. Although they do not contain complex movements, the whole kata is to be performed as a chain of movements without a specific pause.
