Why did you repost the video that I posted and what do you mean, weird? There are different variations of this kata. In this video it was done a "few years" back. I'm not sure what the current JKA way of doing this Kata is, since you're shotokan you should know. I know the Shito Ryu way of doing this kata but it is near identical minus a few differences. The strike goes to the inner thigh in the way I do this Kata and how I've seen other JKA shotokan practitioners do this kata in the last decade. Kanazawa is doing this kata more then a decade ago. I can't answer you why but that maybe shotokan tried to break away from the Shito Ryu way of doing it? Shotokan did get this from Mabuni, not Funakoshi, so that would make sense. Cause I thought it was part of your signature.
