My first (initial) Yudansha ranking was achieved in Shito-Ryu. That was 4 years before my introduction to Taika Oyata. After having been introduced to him, I spent the next year and a half studying with him and modifying the (common) techniques that I was familiar with, to meet the manor that he showed they should be performed. My adaptation of kata performance (from how I had originally learned them) required another year. Once I had done so, I was tested under/by Oyata (himself). As I continued to learn his methodology, I abandoned most (if not all) of the things I had learned while studying Shito-Ryu (this was a choice on my part). It was only after having done so, that my technique improved, and soon after I was allowed to “test” for Yudansha (within Oyata's system).
Considering that the majority of assailants (upon a female) will be male, any attempt to equate the performance of those strikes (or what is being shown to them) to be utilized upon a male by a female, is often pointless.
There has also been a number of requests for technique "clarification" to be provided (here). Aside from the impracticality's in doing so, it is more often faster, and (far) more easily (and quickly) understood when done in person. Our classes are open for anyone to attend, or only come by (at no charge, LOL), and ask any questions in regards to our book(s) and/or the techniques and methodology that we utilize and teach to our students.
Oyata's system of Life-Protection is not for everyone. We've had a number of individual's attend (just to ask questions or "experience" what we are teaching). We don't do the standard "Kicky-Punchy" type of classes, we don't teach adolescents (under 16) and we don't require that our students "spar". Our classes focus, is upon unarmed defensive applications. Though we teach weapons kata, and limited instruction in their application, that study is mainly to enhance the associated hand motions utilized in their use.
Our students are exposed to a number of subjects that don't regularly fall into the (typical) "martial arts" class category (i.e. anatomy, kinesiology, Shodo etc.). Though these subjects aren't as commonly associated with "Life-Protection", they all contain relevant aspects to that study.
When we aren't doing a public or private seminar (somewhere, LOL), we are teaching our classes here (Kansas City, Mo.).
