Hokushin Ittō-ryū
After the Meiji-restoration and the abolishment of the traditional clan system the Kodokan was closed, so in order to continue teaching, Kozawa Torakichi opened his own Dōjō, the Tobukan. There he taught Hokushin Ittō-ryū together with Shin Tamiya-ryū (新田宮流抜刀術) and Suifu-ryū (水府流剣術) (Torakichi's second son Kozawa Jiro Atsunobu (小澤二郎篤信) inherited Suifu-ryū kenjutsu from his own other Dōjō). This Hokushin Ittō-ryū line is also the line of the school which is a member of the Nihon Kobudo Kyokai. Up until today, the Kozawa family is still preserving the teachings of its first headmaster at the Tobukan in Mito.
