This was sensei when he was young. When I need a dose of humility, I watch my Naihanchin, Seisan, and Seiunchin kata performances. Yes… it is a little different than the way we teach it now in the AOKK.

Note: Do not add the side kick to your kata. This was how I learned it under my first Isshin-ryu instructor. Later, I learned this was a hidden kick according to Motobu sensei.  I have also been told that it is a block utilizing the knee.  Harold Mitchum said not to include it in the kata. 🙂
