Accoring to Togakure ryu Ninjutsu Hidensho (a Japanese manuscript of indeterminate authorship, age and provenance currently in the possession of sōke Masaaki Hatsumi, a Budo teacher from Noda-shi, Chiba, Japan), Togakure-ryū (戸隠流, Togakure-ryū?) ("School of the Hidden Door") was founded about eight hundred years ago by Daisuke Nishina (Togakure), who learned shugendo practices as well as Hakuun ryu ninjutsu from Kagakure Doshi. Although the existence of Daisuke Nishina is possible, as a person by that name was found by Koyama Ryutaro in a period work, the history of the system has not been independently verified.
