Tokugawa Yoshinobu, October 28, 1837 – November 22, 1913 was the 15th and last shogun of the Tokugawa shogunate of Japan. He was part of a movement which aimed to reform the aging shogunate, but was ultimately unsuccessful. After resigning in late 1867, he went into retirement, and largely avoided the public eye for the rest of his life. In 1902, the Meiji Emperor allowed him to reestablish his own house as a Tokugawa branch (bekke) with the rank of prince (kōshaku).
