ABSTRACT

This article contributes to the literature on the mechanisms, rhetoric, and limits of mid-Victorian expansion by asking how far late Tokugawa Japan was subject to forms of British imperialism. In September 1862 a British merchant was murdered on the high road between Edo and Kyoto; a year later, a British fleet bombarded Kagoshima in retaliation. By engaging with John Darwin’s concept of the ‘bridgehead’, this article examines the circumstances in which a lonely death on the frontiers of British commerce could be transformed into a Victorian ‘outrage’. It considers what we stand to gain by bringing an imperial history perspective to bear on what remains, for most imperial historians, a largely forgotten conflict. In positing Yokohama as a bridgehead that could gain only fitful purchase in London, it asks new questions about the conduct of ‘gunboat diplomacy’ and the fault lines of mid-Victorian expansion; the place of Japan in British political imaginaries; the nature of informal empire; and the discourses buffeting British expansion in the turbulent 1860s.
