What is "sosuishi-ryu"

is a traditional Japanese martial art founded in 1650 that focuses on Kumi Uchi ( jujutsu) and Koshi no Mawari ( iaijutsu and kenjutsu). The title of the school also appears in ancient densho (scrolls documenting the ryuha) as Sōsuishi-ryū Kumi Uchi Koshi No Mawari(双水執流組討腰之廻) and in the book Sekiryūkan No Chōsen, which was approved and published by the Shadanhōjin Sekiryūkan in 2003. In the Bugei Ryūha Daijiten, Sōsuishi-ryū is cross referenced and listed under the entry/title of "Futagami-ryū." It includes a brief categorization, history and description of the school.
