For those interested in discovering Aikido.

Why the Aikiso was created.

Why were the Aikiso created, and what are they good for?

I have had a minor obsession with the Japanese spear for about 6 years now. It all started with my interest in tearing apart the Aikijo syllabus and making an attempt to understand the purpose of the kata, suburi, kumijo and awase practices. This investigation took me to many places I did not expect. I ended up not only looking deeply into Aikido Jo, but I also started to study the techniques of Shinto Muso ryu Jodo, Atarashii nagenata, and several Sojutsu systems. In these studies, a much more diverse world of “stick fighting” became apparent to me. The “Aikiso” (Aiki-spear) of the Chushin Tani school is part of my effort to illustrate much of what I missed in my normal Aikijo practice.

The Aikiso should not be considered a stand-alone system of spear. As a method of understanding Japanese spear, it is a far cry from the depths of what would be found in a koryu system focusing on the subject- However, it does offer some beginning insights into spear work for those interested. Further I believe that it offers a great deal to those who are looking to better understand the Jo work used in our Aikido system.

The kind of Yari (spear) used in the Aikiso, is often called a “Tanso” or short spear. This kind of Yari would not be seen on the battle field, but would more likely be found around the house as a means of protecting the family if they were threatened. This is the length of Yari often used by Morihei Ueshiba, O-sensei, when he demonstrated Yari technique. When watching the “Aikijo” of O-sensei it is important to realize that he is often demonstrating Yari technique. When I originally realized that much of what O-sensei was demonstrating when he had a stick in his hand was actually Yari and not just a simple jo, many questions arose for me, not the least of which being- how can I practice that?

There is a clean integration between the techniques found in our Aikiso, and most Aikido jo work, especially that found in the Iwama system. Realizing that much of what is practiced in our “jo” work is also Yari and sometimes Nagenata movement, will help clarify many of the techniques. The Aikiso practices, suburi and forms will give those Aikido students who are interested a starting point to both deepen their understanding of Aikijo, and broaden their understanding of Japanese weapons.
