, or (Shintō-ryū Kenjutsu), is one of the names used to describe the collection of sword-versus-sword training-forms (kata) for the long and short sword found exclusively in the Japanese martial arts system Shintō Musō-ryū (SMR).[1] The system comprises 12 standing forms, 8 of which are for the longsword (Odachi) and 4 with the short sword (kodachi).
The core of the Shinto Muso Ryu system has two elements, the jojutsu training forms and the twelve kenjutsu training forms. The origin of these kenjutsu forms are not clear other than it was a part of SMR from the beginning of the tradition, unlike the assimilated arts of Uchida-ryu, Ikkaku-ryu, Ittatsu-ryu and Isshin-ryu.[1] Before creating the SMR, the founder, Muso Gonnosuke, had extensive training and experience in other martial arts. He received a Menkyo Kaiden, a license of complete transmission, in the Tenshin Shoden Katori Shinto Ryu tradition and he was said to have mastered secret techniques derived from the Kashima lineage of martial arts tradition.[1]
Up until the mid-19th century there seems to have been no known name for the tradition, it simply being referred to as "8 longsword and 4 short sword forms". The tradition came to be known as Shintō-ryū kenjutsu in the mid-19th century[2] by research made into the history of SMR by the SMR-practitioner Umezaki Chukichi.
The discovery of the name "Kasumi" Shintō-ryū was made from recent research by the SMR-practitioner Kaminoda Tsunemori, a direct student of Shimizu Takaji[1] and leader of the Nihon Jodokai-group. This research has not yet been verified by independent sources, but the Kasumi designation has been used within Kaminoda's own organization to label the 12 kenjutsu forms.[3] The name Shintō-ryū and Kasumi Shintō-ryū is used interchangeably among the various SMR-Jodo organizations and no consensus has been made on which name is to be used.
