The Yagyu Shingan ryu was handed down from the founder Takenaga Hayato for posterity secretly in the Sendai clan and proliferated in the Tohoku district of Japan.
Yagyu Shingan ryu 'Chikuosha' is lead by Soke Shimazu Kenji who was born during Showa 13 (1938). At a young age (15) he became a student of Aizawa Tomio. 教傳所竹翁舎竹永隼人兼次（直入・金次・勝廣）. A classical martial arts historian, and high profile bone setter (Honetsugi) by occupation, Shimazu Kenji has studied and researched with great concern several styles (Kano den, Yorifuji den and Hoshi den) of the tradition in an endeavour to discover new or collate old facts. He received mastery of the Yagyu Shingan ryu from both Headmaster Aizawa Tomio and Headmaster Hoshi Kunio. As a result Shimazu Shihan is a descendant to and custodian of the Yagyu Shingan ryu. Aizawa Tomio Sensei studied the Yagyu Shingan ryu Sendai line from Kano Yasuyoshi Kuniharu and the Yagyu Shingan ryu Edo line from Yorifuji Daizaburo. Hoshi Kunio Sensei studied the Yagyu Shingan ryu Sendai line from Hoshi Hikojuro Kuniyuki. Five generations following Koyama Samon, Hoshi Shinkichi (Masayoshi) became the headmaster in Sendai and he became known as the Restorer.
Shimazu Kenji's dojo is located in Tokyo where he continues to head the Yagyu Shingan ryu Heihojutsu Kyodensho Chikuosha in Japan, Australia (Philip Hinshelwood) and Northern Europe (Per Eriksson).
Entrance into the tradition is by invitation only.
