Excerpt: Part I investigates the trans-imperial linkages between Japan and the United States during Japan’s colonization of Hokkaidō around the 1870s. Chapters 1 – 3 consider the role of three American professors, William Smith Clark, William Wheeler and David Pearce Penhallow, who were hired to establish an agricultural college as part of the colonial development of Hokkaidō. I argue that these American professors contributed to Japan’s colonial expansionism in at least three ways: by helping the Kaitakushi physically transform Hokkaidō into a Japanese settler colony, by spreading a colonial worldview according to which the Ainu were portrayed as a primitive, dying race similar to Native Americans, and finally by acting as propagandists for Japanese expansionism after their return. Chapter 4 considers continuing links to American technologies of settler colonialism in the next generation through the writings of Satō Shōsuke on Hokkaidō’s colonial status. Satō graduated in Sapporo Agricultural College’s first class and later studied land policy in America before returning and becoming president of his alma mater.
