A key principle in Wadō-ryū is that of "tai sabaki" (often incorrectly referred to as 'evasion'). The Japanese term can be translated as "body-management," and refers to body manipulation so as to move the defender as well as the attacker out of harm's way. The way to achieve this is to 'move along' rather than to 'move against'—or harmony rather than physical strength. Modern karate competition tends to transform Wadō-ryū away from its roots towards a new generic karate that appeals more to the demands of both spectators and competitors.
