the most popular school of jujutsu of the time (1848–1864). Iso taught 5000 students in that time. After the Meiji Restoration of 1868 the study of jujutsu fell into decline generally and this affected the Tenjin Shinyo-ryu as well. Training methodology The training methodology, as with most koryu systems, is kata based or a form of pre-arranged fighting. Students learn the specific subtleties, or the more hidden meaning of the form, through the continuous repetitions of the katas. There are over 130 kata of this classical jujutsu, unarmed combat teaching from seated positions, standing positions, weapons defence, and also includes special healing methods and resuscitation (kappo). Certain katas are subject to secrecy, due to the nature of lethal effects and subject of martial traditions. The kappo or resuscitation techniques, were a secret, however Kubota now teaches at Kōdōkan to the leading teachers at the seminars. The higher level of kata, not only relates to the aspect of physical movements, but the deeper inner meanings, or link between the philosophy, and mindset of the practitioner. Such kata are taught only to students with many years of commitment and experience. Tenjin Shinyo-ryu Today With the 5th headmaster, Iso Mataemon dying without designating a successor, the 4th headmaster passed the entire body of knowledge required for full mastery to three Shihans (menkyo kaiden's with impeccable moral character) that were identified and designated as such by the 3rd headmaster (the grandfather of the 5th headmaster), and a fourth as selected by the 4th headmaster to fulfill the "divine scheme" of transferring the school outside of the family lineage. One of these Shihans, Torijiro Yagi, was able to complete and learn the additional teachings provided to them by the 4th headmaster, and as such is the one and only true and complete lineage of Tenjin Shinyo ryu today. Although there exist a number of individuals who received Menkyo Kaiden awards in the art from legitimate headmasters of the past, none of them have the final "keys" to be considered as having received the full transmission. Torajiro Yagi passed the full transmission of the body of knowledge to Fusataro Sakamoto, who in turn passed the full transmission of the body of knowledge to the one and only master of the ryu today, Kubota Toshihiro. As the leading active teacher is Toshihiro Kubota whose legitimacy in preserving the teachings of his teacher Sakamoto Fusataro is supported by
