1960’s. Stan Pranin: “This photo was a personal favorite of Morihiro Saito Shihan. In the 1970s and 80s when I was training in the Iwama Dojo he would sometimes bring out this photo to show students the correct position to assume. He attached great importance to this exercise and said that O-Sensei would always teach tai no henko at the beginning of classes. Do you?”
