Dave Lowry's "Jo: Art of the Japanese Short Staff"
I was reading a copy of the title book on jo (great book by the way), and I was curious as to the 31-count jo kata that he presents. In many ways it is identical to the 31-count jo kata as taught by Morihiro Saito Sensei and the Iwama style, but there are slight differences. Does anyone know where this kata came from? I know Lowry practiced Shindo Muso ryu jodo and Yoshinkan aikido in addition to countless other arts including Yagyu Shinkage ryu.
