The school was founded in the 1820s, towards the end of the Edo period in Edo (nowadays Tōkyō) by samurai Chiba Shûsaku Narimasa, who was considered the last kensei
(sword saint) of Japanese history.
He founded the school on the principles of Ittô-ryû
and his family style, the Hokushin Musô-Ryû. Due to his good reputation and his fame as Kensei, although still managed by the Kaiso
(founder), the Hokushin Ittô-ryû was one of the three largest and most famous schools of the Bakumatsu period. These so-called San-Dai-Ryû
(three largest schools) were the Hokushin Ittô-Ryû, Shintô Munen-Ryû and the Kyoshin Meichi-Ryû.
In the Edo period, there were two main lines of Hokushin Ittô-ryû Hyôhô. One was the Genbukan, the line of the style founder Chiba Shûsaku Narimasa and the other the Chiba Dôjô of his younger brother Chiba Sadakichi Masamichi. Due to the size of the school and the many awarded teaching licenses, in the Edo period many different lines of the Hokushin Ittô-ryû Hyôhô formed. Those lines acted completely independently of each other and in the the present time are no longer in any connection.
