Togakure ryu (戸隠流) [Bugei Ryuha Daijiten (武芸流派大事典); 1978]
Takamatsu Toshitsugu organized this genealogy into a densho according to the oral teachings (kuden) of Toda Shinryuken. Toda Shinryuken Isshinsai passed away in 1908 at the age of 90. According to the genealogy, a person named Ikai was the founder and split from the Hakuun ryu of Hakuun Doshi (c. 1181) and became Iga ryu and Koga ryu ninjutsu. The lineage passed to Momochi Sandayu and joined with Kishuhan Natori ryu. From Toda Nobutsuna it was transmitted through the Toda family. As it is referenced from various transmissions such as kuden, the genealogy has been embellished; it is thought the genealogy is older than the actual information presented in the sources.
