When Shimizu Sensei opted into the idea of incorporating Shindo Muso Ryu Jodo (SMRJ) into the All Japan Kendo Federation (AJKF) (ZNKR then) he knew about the controversies this action would create.
Besides his desire to see Jodo grow worldwide after seeing and teaching such deserving students as Donn F. Draeger et al. he was truly concerned that such a small membership of practitioners within Japan might dwindle to obscurity. Many of his contemporaries, even close associates opposed his decision to “popularize” Jodo under the much larger Kendo umbrella. There were two main concerns voiced; first that many kendoka (kendo practitioners) performed waza (technique) at odds with Koryu (older) traditions, (ie. A higher stance floating the hips and having a raised rear ankle) and second that over time Jodo would lose its identity within the larger political framework.
