Eihachi Ota demonstrates a powerful Bo Kata.

Sensei Ota’s use of core strength to generate velocity is perhaps his greatest trait.  You can see how his stances (which are generally low and wide), help him to control his balance, etc., while he delivers effective strikes – and it’s safe to say that he leverages “winding up”.  Here is another video of a ‘Shiru Taro No Kon’ Bo Kata that he performed for a small audience at Phillip’s Karate Dojo in Whitby Ontario Canada several years ago.  Capturing the entire Kata in one frame – from a greater distance helps to better visualize Ota’s use of core strength to deliver effective strikes.  Make no mistake about it – Ota’s delivery of powerful technique is unique among many of his Okinawan colleagues.
