Hello, In my experience, although slight differences can be found from instructor to instructor (and group to group), generally speaking, the Kata done in the three International Wado groups are very similar (to each other) - and certainly have fundamental Wado principles in common. When I see Shintani Wado-kai versions, they do not appear to share these principles - often they contradict them! Granted the embussen maybe similar, buts that's where it stops. A bit of info for you: Taisabiki - is not unique to Wado . How it is utilsed is, but not Taisabaki per-se – most styles have taisabaki. The name of Pinan Nidan and Pinan Shodan kata were switched by Funakoshi (Shotokan) when he re-named them Heian’s Chitsu
