Tosa Domain
The ninth generation sōke was Hayashi Rokudayū Morimasa. Hayashi introduced a set of techniques executed from the formal seated position seiza. These techniques are thought to have been developed by Hayashi's kenjutsu teacher, the Shinkage-ryū swordsman Ōmori Rokurōzaemon, and are said to be influenced by Ogasawara-ryū etiquette, hence starting from seiza. They were taught alongside Eishin-ryū as Ōmori-ryū. Hayashi was responsible for introducing the school to the Tosa Domain at the behest of the ruling Yamauchi family.
