This mid-19th-century map of Japan by A. J. Johnson and Benjamin P. Ward provides a comprehensive overview of the Japanese archipelago during the late Tokugawa shogunate (Bakumatsu period), created shortly after the opening of Japan to Western trade following Commodore Perry's naval expedition. The primary map illustrates the main islands of Honshu ('Nippon'), Kyushu ('Kiusiu'), and Shikoku ('Sikok'), with historical provinces highlighted in pastel hand coloring. Mountain ranges, coastal bathymetry, towns, and sea routes are intricately depicted using geographical compilations by Philipp Franz von Siebold alongside survey data from the U.S. Japan Expedition. Two detailed insets complement the main map: the upper-left inset features Hokkaido ('Yesso'), Sakhalin, and the Kuril Islands, while the lower-right inset provides a detailed harbor chart of the Bay of Nagasaki, one of Japan's key historical treaty ports open to foreign trade. The sheet is enclosed within Johnson's signature decorative fretwork border.
