Shintō Musō-ryū
is a traditional school ("koryū") of the Japanese martial art of "hojōjutsu". Today, Ittatsu-ryū has been assimilated into the traditional school of Shintō Musō-ryū. This particular school of "hojōjutsu" was created in the late 17th century by Matsuzaki Kinueimon Shigekatsu, the third Shintō Musō-ryū headmaster. The modern Ittatsu-ryū system comprises 24 training-forms ("kata"), grouped into 3 different series.
