Choho

Togakure-ryū (戸隠流) is a historical tradition of ninjutsu known as the "School of the Hidden Door", allegedly founded during the Oho period (1161–1162) by Daisuke Nishina (仁科大助), who learned his original fighting techniques from a Chinese monk named Kain Dōshi. However, the history and early lineage of Togakure-ryū may be impossible to verify due to the antiquity of the time period and its claimed historicity has been disputed by Watatani Kiyoshi, writer for the Bugei Ryūha Daijiten. After Togakure, the title of Sōke was recorded by Toda Shinryuken Masamitsu to have been passed down through other practitioners that kept the style secret from the outside world.
