is a iaijutsu koryū founded by Hasegawa Chikaranosuke Eishin (or Hidenobu)(長谷川主税助英信) as a continuation of the teachings he received in Shinmei Musō-ryū. After the death of the eleventh headmaster, Ōguro Motoemon Kiyokatsu, the school split into two branches or ha. One branch, the Shimomura-ha (下村派), was renamed by its fourteenth headmaster Hosokawa Yoshimasa to Musō Shinden Eishin-ryū (無雙神傳英信流). After studying under Hosokawa, Nakayama Hakudō created his own school which he called Musō Shinden-ryū (夢想神伝流) in 1932.Yamatsuta, p. 16.. The other branch, the Tanimura-ha (谷村派), was renamed Musō Jikiden Eishin-ryū during the Taishō era (1912-1926),. by its seventeenth headmaster, Ōe Masaji, who incorporated the Shimomura-ha techniques and rationalized the curriculum.Iwata, p. 97.
