Tenshin shinyo ryu is a school of jujutsu founded by Iso Mataemon (also known as Masatari Yanagi). It is particularly famous for its vital-point attacks (atemiwaza), immobilization methods (torae), and strangleholds (shimewaza). It is generally considered to have been the result of a fusion of two ancient schools, the Yoshin ryu and the Shin-no-Shindo.
