On November 25, 2017, another seminar of Kashima Shin Ryu kenjutsu, led by Andrzej Bazylko (chuden) sensei, was held for instructors and future instructors. Repetition of kihon dachi was the introduction to in-depth work on ura-dachi – the second series of kenjutsu kata, which is composed of 10 kata and teaches how to reverse the situation of a loss, which gives the impression that the opponent will win.
