In shotokan it is always told the Azato Itosu Sensei created the pinan kata series
but in shito ryu it is told that Kenwa Mabuni Sensei created the pinan kata series
which one would you think is more right?
BTW for those that dont know Mabuni sensei contributed a lot of kata to shotokan.
Funakoshi sensei would send his senior instructors to Mabuni sensei to learn additional kata that was latter include in the shotokan syllabus, there kata there were about 8 kata add.
so its not far fetch about the pinan kata comming from Mabuni sensei
My shotokan books say Itosu and the shito ryu says mabuni. ya they dont help much.
piana kata series from my understanding came from several advance kata such as passia and kusanku. the other theory i have see is the the came from the chinese form of chiang nan.
Soken Matsumura? i haven’t heard that theory.
I your theory Sensei Scandal that they both collaborated on it. it makes sense.
OC Bujinkan thansk i have read that one though, its a good article
