Kanō Jigorō, the founder of judo, studied Tenjin Shinyo jujutsu for several years under two leading exponents of the day, Fukuda Hachinosuke and 3rd generation headmaster Iso Mataemon Masatomo. The Tenshin Shin'yō-ryū, along with the Kitō-ryū, played a role of seminal importance to the development of Kanō's judo system. Although modified for safe sport use, the influence of the Tenjin Shin'yō-ryū can be seen today in many of judo's core throwing techniques such as "seoi nage" (shoulder throw), "harai goshi" (sweeping hip throw) and "osoto gari" (outer reap) to name but a few. The Itsutsu no kata, or the five forms, of Kodokan judo preserve techniques of an esoteric nature found in the Tenshin Shin'yō-ryū's "five teachings of the kuden" kata and techniques from the Kime no kata are said to show the influence of Tenjin Shin'yō tactics. In this way while creating a modern sport Kano was able to preserve some aspects of the Tenjin Shinyo Ryu in his art and it is for this reason that contemporary judo participants tend to show such an interest in this particular ko-ryū jujutsu form.
