Old Waza Names
Oe Masamichi Shikei, 17th Grandmaster of the Tanimura-ha of Muso Jikiden Eishin Ryu, died in 1927. It was about this time when the names of the forms of the Shoden, Oku Iai Tachi Waza, and Oku Iai Suwari Waza were changed. Why the names of the Hasegawa Chuden forms remained unchanged, I don't know.
In 1932, Nakayama Hakudo founded a new style of sword-drawing art, which he called the Muso Shinden Ryu Batto Jutsu at first, then Muso Shinden Ryu Iaido later. He used the new names of Oe Masamichi for Okuden, but the traditional names for Shoden. It is somewhat absurd that more traditional versions of Eishin Ryu have the "new" names, today, and the "modern" Muso Shinden Ryu kata kept the traditional names.
