Naihanchin kata is the solo representation of a pro-active collective of crossed arm grappling and restraining techniques meticulously designed and engineered to arrest and subdue a single opponent with whom contact is never lost.

When applied, Naihanchin facilitates the non-brutal process of effectively negating the opponent's attempts to extricate himself. When he tries to stand-up or pull away, he is put back down, tumbled and brought back to 'rest' (arrest). There isn't a single punch, block, strike, or kick, in the whole kata!
