Gyokko-ryū Kosshijutsu "Jewel Tiger School"

Gyokko Ryu Kosshijutsu: Jeweled Tiger School

Established in the 1100s, Gyokko Ryu Kosshijutsu specializes in techniques centered around Kosshijutsu (attacks against muscles) and Shitojutsu (use of the thumbs and fingers). Renowned for its powerful blocks and balance-breaking methods, Gyokko Ryu distinguishes itself by advocating the use of knuckles to target muscle attachment points. The Kihon Happo, originating from the first two levels of this school, is considered foundational for all martial arts, emphasizing the backbone role of Kosshijutsu.
