As I go through our Kata thread, I find names of Kata that have influenced the "Modern" kata we know today, such as Passai etc......
I recently heard of a Kata called Channan. Does anyone know of this kata?
I'm led to believe that it was used as the basis for the heian/pinan group of kata - Can anyone enlighten me further?

An insteresting article, the Conclusion of which reads

"While more research, such as in-depth technical analysis of Motobu's Shiragunm no Kata, needs to be done, the evidence at hand seems to point not to a "long lost kata" but rather to the constant and inevitable evolution of a martial art. Although there is opposition, most of the primary written materials point to the fact that Itosu was indeed the originator of the Channan/Pinan tradition, based upon his own research, experience, and analyses. However, in either case, Itosu Anko and his efforts left a lasting mark on the fighting traditions of old Okinawa, and will probably always be remembered as one of the visionaries who were able to lift the veil of secrecy that once enshrouded karatedo."
