Niten Ichi-ryū
It is believed that Hōzan, or one of his disciples had transmitted the art of the jitte to Hirata Shokan, Miyamoto Musashi's grandfather. It is for this reason the Miyamoto family taught the art of the jitte for many generations. Musashi himself is said to have learned Jion's Nen ryū through Hōzan's jitte, which would have greatly influenced the single-handed method of Musashi's Hyōhō Niten Ichi-ryū.
