The video is

「Koshinomawari Iaijutsu」 Muko Nito (Henka) of 『Bokuden-ryu Jujutsu Koshinomawari Iai Heiho』.

   The video shows the training scene at a dojo in Okinawa (Dento Budo Tendokan).

   One of the features of the training is that the students perform [Jujutsu] and [Koshinomawari iaijutsu] (Iai) with large and small swords (Uchikatana and Wakizashi), and both large and small swords were used an actual sword for the training.

   I am very grateful to be able to train at the Dento Budo Tendokan Dojo of Okinawa.

   I am grateful to the people around me, my family, and  Kai Kuniyuki Master , and I will place importance on both 「continuity」 and 「improvement」 of 「mind, technique, and body」.
