Tokugawa Iemochi
After the death of Tokugawa Iemochi in 1866, Yoshinobu was chosen to succeed him, and became the 15th "shōgun". He was the only Tokugawa "shōgun" to spend his entire tenure outside of Edo: he never set foot in Edo Castle as "shōgun". Immediately upon Yoshinobu's ascension as "shōgun", major changes were initiated. A massive government overhaul was undertaken to initiate reforms that would strengthen the Tokugawa government. In particular, assistance from the Second French Empire was organized, with the construction of the Yokosuka arsenal under Léonce Verny, and the dispatch of a French military mission to modernize the armies of the "bakufu".
