More detailed information about the history of Kashima Shinryu can be found in the book "Legacies of the Sword" by Karl Friday. The history below is a summary and may not have the historical accuracy of Karl Friday's research. The sword style known as Kashima Shinryu (lit. divine school of Kashima) developed during Japan's turbulent medieval period. Records of sword study associated with the Kashima Shrines, located in the provinces north of modern Tokyo, go as far back as the 14th Century (legend takes them back to the 8th Century), and it is said that the Kashima teachings are the core of Budo.

There are a number of "sets" of techniques depending on the weapons being used (for example sword against sword, spear against spear, sword against spear, etc.). The five sword against sword sets are listed below. These are kumitachi or paired techniques where person who "receives" the technique (uke) is normally the senior student (or teacher). The names are given here for reference, particularly for students studying the techniques. They mean very little without instruction and demonstration.

Kashima no Tachi is the name given by Inaba sensei to what he teaches. The techniques derive from Kashima Shinryu which is an older traditional Japanese martial art (koryu), of which we concentrate on the kenjutsu (sword) techniques. Kashima Shinryu developed during Japan's turbulent mediaeval period, and its teachings are believed to be the core of Japanese martial arts. Swordsmanship helps develop well aligned and clearly focused movement, with power and subtlety.
