ATC - Rocian Gracie Jr Brazilian Jiu-Jitsu

Judo is made up of many styles of Jiu-jitsu whose masters Kano had studied with. The most notable were Jikishin-ryu, Kito-ryu, and later Fusen-ryu would be incorporated for its groundwork (ne waza) as Kano would ask the style's head master, Mataemon Tanabe for his syllabus. Yokiashi Yamashita (Kano's Chief assistant) would add his knowledge of Yoshin Ryu ju jitsu and Tenshin shinyo Ryu ju jitsu, both of which, he was a master.
