 Masamitsu disagreed in particular on the use of "tate-hiza" and "tachi-ai" as practical sword drawing postures.He thus based his "kata" on the "seiza" posture as he had learned it in the Ogasawara-ryū, a school of etiquette or "reishiki".Though the form of the "kata" themselves were taken from what he had learned with Hasegawa, they were modified to conform to the five forms of sword-drawing as taught in the Yagyū Shinkage-ryū.
