Looking to crowd source some information here on Wankan, Matsukaze kata. From what I understand it is a very old kata with Tomarite roots and today seems to largely belong to Shito-ryu. The first thing that I noticed is that shotokan does a much different version than everyone else. I know that the two versions must have a branching off point somewhere in time since there is one common sequence near the end of each one. Do we know if this was a Funakoshi edit? If so, why did he make such major changes? First impressions tell me that the Shotokan version is much less complex and almost lends itself to a lower level kata (not a negitive thing in the least). It could be that I'm not looking close enough and there are some themeatic overlays between the two versions that I'm missing. But overall they seem like very different kata.
Shotokan (can't go wrong with shotokankataman)
