Gichin Funakoshi's Kyusho
Yes even a style as "Taditional" as Shotokan was originally built on an understanding of Kyusho by it's founder.
In fact he was so entrenched that he published his notes on Kyusho in his legendary text "Karate-Do Kyohan".
Now in the older "modern Publication" there was only a brief account of the Kyusho, however in the Original Version and in this full restoration,there are now the original 35 pages included.
These pages are eerily close to those of Hohan Soken (Fuse Kise - see film), in their anatomical locations, structures and implications, devoid of TCM terminology or use.
Section 6, Chapter 2, Funakoshi begins:
"As for the names of the Kyu-Sho or Vital Points, I used the ones that are generally and most widely used, as much as I could. However, for Vital Points that have not been named since ancient times, I gave them names for the sake of convenience. Alternative names and commonly known names are shown in parenthesis."
His number 10 Target is called
10) "Matsu-Kaze" or Pine Wind (Fu-getsu - wind-moon)
"This is located on both sides of the neck, where the Platisma Muscle, Trapezius Muscle and Sternocleidomastoid Muscle come across. In other words, you strike the Caroid Artery. The cause of death is due to an overwhelming stimulation of the general Carotid Artery and Vagus Nerves, leading to a sudden, violent change in the blood circulation and loss of Motor Sensory functions."
Well not quite called Large Intestine 18... but this anatomical depiction and implication is in the Hohan Soken Notes, The Fujita Scrolls and over 20 other schools... yes even in Shotokan.
