Shintō Musō-ryū
A collection of eight long-sword and four short-sword kata, including one two-sword kata are found in Shintō Musō-ryū. Neither the twelve kata nor the art itself had any known name in the Shintō Musō-ryū until the mid-19th century when "Shintō-ryū kenjutsu" started to be used and specific names were given for each of the twelve kata. In the 20th century, "Kasumi Shintō-ryū" or more recently "Shintō Kasumi-ryū" has surfaced as the original name for the twelve kata as taught in the Shintō Musō-ryū, though it is not yet an official name.
