 The Naifanchi (Daipochin) kata comes from the famous Okinawan karate-ka, Choki Motobu, who is famous for his actual active testing of bunkai in real fighting situations.This sometimes happened by suspicious means, and many a teacher would watch this kind of conduct with disapproving eyes.It was said that Choki Motobu knew only three kata, the Naifanchi series, Wansu, and Passai Guwa.
