Gyokko ryu Kosshijutsu 玉虎流骨指術
Gyokko ryu, the “Jade Tiger Tradition” is a school of kosshijutsu, a method of unarmed combat that includes striking to vital areas, joint locks, and throws. According to legend, this tradition was brought to Japan from China by either a princess, a general, or an imperial bodyguard after the fall of the Tang Dynasty in 1100 AD. According to historical records, refugees from the imperial family did make their way from China to Japan during this time period.
Characteristics of this tradition include using footwork to flank an opponent, rather than face them head on, as well as applying elements of deception in order for a smaller opponent to defeat a larger one. Additionally, methods for using concealed weapons are also a characteristic of this school.
The tradition itself consists of rolling break falls, fundamental defensive locking, throwing, and striking patterns, unarmed defense and offense against an unarmed opponent, unarmed defense against a short, edged weapon, and unarmed defense against a sword. In modern application,
Gyokko ryu Kosshijutsu, along with Koto ryu Koppojutsu, form the basis for Togakure ryu Ninpo Taijutsu, the tradition which Hatsumi Masaaki’s Bujinkan Dojo has become famous for.
