Tenjin Shinyo Ryu was one of the most complete and renowned schools of traditional jujutsu of XIX century in Japan. It is considered as the father of Kodokan Judo, where Jigoro Kano borrowed this atemi waza, katame waza, nage waza and kappo waza among many other techniques. As has happened with other koryu, Tenjin Shinyo Ryu is hardly practiced today. Fortunately, after extensive research, we have recovered information from the past and ancient documents that have been of great help in carrying out this work. We have conducted a study about its history, its lineage, its curriculum with all the kata, vital points of the body, the characteristic kamae of this school, its techniques in idori and tachiai as well as the famous kappo waza. With this work, we put at the service to all lovers of Japanese martial arts the extraordinary beauty and singularity of the Tenjin Shinyo Ryu Jujutsu.
