Hokushin Ittō-ryū
In the Taishō era, Bushido as the way of the merchant was advocated by industrialist Shibusawa Eiichi (1840–1931), known as the "father of Japanese capitalism". Shibusawa was also a warrior who learned Shindō Munen-ryū and Hokushin Ittō-ryū. He spent some time as a vassal of Tokugawa Yoshinobu, and since the Meiji era, he was a businessman and involved in the establishment of hundreds of corporations.
