As with other Itosu kata this version introduces specific new movements (and through them, new concepts) that build on the existing catalog of techniques. Many of the movements are in fact 'basic' but they are presented in combination with other unique waza that is not seen elsewhere. In this case, one of the most notable introductions is an empty-hand defense against a bo (staff). In keeping with Shotokan fundamentals, the defense requires the practitioner to seize the initiative when threatened directly and to use economy of motion.
