Shintō Musō-ryū
The main students of Gonnosuke's art were the men charged with policing the Kuroda clan's domain ("Kuroda-han"). During this period other schools ("ryū") were created and taught in the Kuroda-han and in the various branches of the Shintō Musō-ryū system. During this period, two newly created schools which included the art of the police baton ("jūtte"), (among other weapons) and the art of restraining a man with rope ("hojōjutsu"), were taught within the branches of the Shintō Musō-ryū as a complement to the arresting ("torite")-arts.
