Shochugeiko, day 4

We're four days into Shochugeiko, with today's technique being sankajo.

In the early morning class, we looked at shomen uchi sankajo osae II in depth, focusing on the strike, pivot and entry into the sankajo lock. Sensei emphasized the importance of the circle that uke's wrist makes, starting with the strike, moving down a little as shite pivots, bring the arm back, and then the wrist moves back up as the sankajo lock is applied. Easy, right?
