Interesting demonstration 2019 of Toyamaru Ryu forms by Kakuseikai, International Batto-Do Federation in the time-honored Butokuden, Kyoto. The preference for oblique cuts as a characteristic of Iai-Jutsu schools becomes clear (note: it does not mean ›Jutsu‹ in the sense of ›Naruto‹. Iaijutsu claims to train effectively for real combat situations. The Toyama Ryu has a special role in that it was developed for military training of officers.). There is a relationship between fighting scenes and Okuden forms of Muso Shinden Ryu.
