 Of key important to Okabayashi's approach was a traditional concept of movement common to most "koryū" styles but not present in the teachings of most contemporary Daitō-ryū teachers.This concept was called 'hitoemi', and describes an idiosyncratic movement, readily seen in any Japanese period drama or "koryū" art, where the warrior class walk and perform techniques while lining their bodies up 'on one line' as they move forward.Okabayashi during his lengthy morning sessions acting "uke", or receiver of techniques for Takeda noticed that his movements always seem to conform to this principle while other teachers, even those who had been taught by Tokimune did not always move so.
