About Gyokko-ryu Kosshijutsu

Gyokko-ryu koshijutsu is one of the nine schools that make up the content of the modern ninjutsu taught in the organisations descending from Takamatsu Toshitsugu and Masaaki Hatsumi. Koshijutsu means literally the art of bones and fingers and denotes a way of fighting that does not try to overpower the opponent but to strike him where the body is most vulnerable: at the muscle attachments, at nerve points and at the joints. Strikes are delivered with the fingertips, the edge of the palm and the thumb, and have a small range; pain and the slackening of a muscle take the place of strength. To this belongs work with the opponent's balance and the passage into locks and takedowns. Characteristic is the teaching on stances, of which the school has several clearly distinguished, and on distance, which the student is to keep such that an attack ends just short. Tradition places the school's origin in the twelfth century and links it to Tozawa Hakuunsai. The same must be said openly here as with the other schools of this circle: the documentability of the medieval lineage is disputed among historians, and written sources that would confirm it independently of the school's own account are not available. What is securely documented is the line of transmission in the twentieth century.
