Tokugawa Iesato
Shibusawa had served in various capacities for the last shogun of Japan, Tokugawa Yoshinobu. After the Tokugawa shogunate ended, Shibusawa continued as a friend and political ally of Yoshinobu's son Prince Iyesato Tokugawa (also known as Tokugawa Iesato). Together, these two impressive statesmen Eiichi Shibusawa and Iyesato Tokugawa strove to maintain democracy in Japan and promote international goodwill with the United States and with Japan's other allies.
