Hi all, Greetings from Australia. Unfortunately we cannot attend the dojo atm which gives too much time to think. Anyway interesting reading. One way of looking at the Goju kata groupings could be: Style 1 Suparempi, seisan, sanseru, shi sho chin, with Sanchin as the base. Style 2 Kururunfa, Seipei, Seiunchin, Saifa with Tensho as the base. It seems clear from the intent that Gekisai Ich and Ni Were to be Seperate non style specific (still well worth practicing) kata. In The Meibukan we also train a third “group” again of 4 plus a central base 5th kata. I would be interested feedback And if anyone sees merit in these groupings.
