The concept of pressure points spread through the Tamil martial art called Varma kalai, which is a martial art that concentrates on the body's pressure points. The concept of pressure points is also present in the old school Japanese martial arts; in a 1942 article in the Shin Budo magazine, Takuma Hisa asserted the existence of a tradition attributing the first development of pressure-point attacks to Shinra Saburō Minamoto no Yoshimitsu (1045–1127).
Hancock and Higashi (1905) published a book which pointed out a number of vital points in Japanese martial arts.
Accounts of pressure-point fighting appeared in Chinese Wuxia fiction novels and became known by the name of Dim Mak, or "Death Touch", in western popular culture in the 1960s.
While it is undisputed that there are sensitive points on the human body where even comparatively weak pressure may induce significant pain or serious injury, the association of kyūsho with notions of death have been disproven.[failed verification]

Yoshimitsu then mastered a technique for killing with a single blow. Through such great efforts, he mastered the essence of aiki and discovered the secret techniques of Aiki Budo. Therefore, Yoshimitsu is the person who is credited with being the founder of the original school of Daito-ryu."
