This class focuses on Naihanchi kata as a study of space rather than a study of bodies. Hanshi Juchnik works through the trailer movement seen in slow film exposures (the sparkler effect), the one-dimensional way humans prefer to see things, and breaks down the first motion of Naihanchi using the strings concept to show how one hand naturally moves the other. The discussion covers the elbow and oi-zuki applications, half right angles that produce the seven-five Octagon shift, finding number one on the Octagon, working three motions from Juni Ippo against a partner, the marriage between tori and uke, the Peruvian Paso analogy for gliding movement, and subtle evasive movement that comes from body rotation mechanics rather than visible footwork.
