The Tenpō-Era (1830–1844) Map of Matsumae-no-shima and the Institutionalization of Tokugawa Cartography

Japan’s early modern Tokugawa government (1603−1868) sponsored a series of projects of national mapping. The Matsumae family, ruling what is now Hokkaido, were loosely incorporated into these projects. It was only during the last of these, in the Tenpō era (1830−1848), that their lands were represented in the same manner as the rest of Japan because the central government made the final Matsumae-no-shima map. This article examines the production of this final official map of Japan’s north to argue that the Tokugawa’s institutional mapping made this region part of the nation through its own mapping framework, distinct from the cartographic forms with which national or imperial states are usually associated.
