What Constitutes a Location as Being Considered a Kyusho Point?

 There is a common misconception (IMO) about what a kyusho point actually is. Over the past 30+ years, I've had the opportunity to investigate, explore and experiment with most all of the popular theories. Most all, I've been able to debunk, dismiss and/or ignore as being irrelevant (as far as applicability for a defensive situation).

 Most every instructor (or hack) that I had encountered (prior to my studying with Taika) attempted to apply some irrelevant aspect to the application and/or location of the kyusho points. Looking back in hindsight, it's now obvious that those individuals hadn't a clue as to the how, why or even where the points were located where they were.

 The most popular (theory), has always been the meridians (utilized in acupuncture). It was also the easiest to dismiss (especially after having studied and learned about it). It's become the biggest money maker for charlatan's looking to make a quick buck off of part-time (if not wanna-be) martial artists. This was one of the first things that Taika informed us about after we began studying with him (it isn't the problem in Okinawa, that it is here evidently).

 From studying with Taika, I learned to observe how we (as humans) move, walk and react. Kyusho, or Pressure points (“PP”as they're more commonly referred to) are located throughout the whole body. They don't follow any meridian lines, nor do they only work during certain times of the day or season. The fact that some are located near to those lines or points is (simply) coincidental. The vast majority are not, and those locations hold no relevance (to what we do).

 There are many different routes that can be explored when attempting to discern what does, and what doesn't constitute a relevancy to what we do. And I've been down most all of them. Fortunately, I was lucky enough to begin studying under Taika (before becoming too cynical about all the frauds that are out there).

 The fact that there was an obvious, honest-to-god expert on the subject, that was saying that all the BS, was just that, BS! Was refreshing (to say the least).

 Taika's manner of instruction, though oftentimes frustrating, there was never any kind of implied mysticism, or . When Taika exampled striking (or whatever) a location, he simply stated “here”.

 Over the years, he has offered various guidelines to us (in relation to performing certain actions/techniques). My associate and myself correlated 6 of the most common ones, for use when learning Tuite (which are our 6 Basic Tuite Principles). He has dropped similar hints in regards to PP use and locations.

 Of late, my associate and myself have begun correlating those hints, in conjunction with known PP's and have begun cataloging them into an instructional manual (for our student's). Our research into locating both known and unknown locations, has enlightened much of our other research (kata, tuite, combinations, even striking) and vice-verse.

 Of the numerous factors involved with what constitutes a PP (and there are many), it isn't one factor that stands out. It is a collection of multiple factors that need to be present for a PP to exist. The ingredients, though varied, are not all, always present nor even relevant. Many are situational, and only applicable for/in certain circumstances.

 There are individual commonalities that can be used as a base guideline for the simpler locations, but the majority have certain prerequisites that need to be met before they would be considered usable.

 In our schools requirements, we've listed that our students have to learn/understand the body's ROM and basic anatomy (bones, muscles, nerves and organ locations). It isn't any one of these subject's that guides the student's understanding of PP's. It's a combination of all of them. The majority of proposed methodologies out there today, push any one, or (maybe) two of them. When listening to Taika, it becomes clear that there is no one or two factor's that PP's are derived by. It's dependent upon the point's location, and the relevance of the associated limb's action and/or position. Those points located upon the torso, are often associated to the actions of the various limbs and their actions/positions.

 It's for this reason, that many of the “charts” previously composed were dismissed as incorrect and/or irrelevant themselves. Of course without understanding the associated positions (necessary to utilize the referred to PP's) those charts would be useless.

 It is our goal at present, to collect and list the PP's that we presently know at this time, and to list their application and any relevant factors required to their application. Having seen other attempts at doing similar projects, we are familiar with the shortcomings associated with them. We are hopeful that these can be avoided when assembling our listings.

 The more difficult task, will be organizing the instructional methodology for presenting the information to students. In the past, various locations where identified, then the relevant situations and applications were demonstrated (which were then practiced by the attending students). This worked well for the student's in attendance, but anyone who wasn't present (at that time) was at a loss to receive equivalent instruction. 
 If (when, LOL) we have completed our project,  that will hopefully be alleviated.
