The newly established Meiji government sent a large delegation on a tour of Western countries to report on how Japan might modernize its political, economic, and social infrastructure. This embassy of some fifty top officials was headed by Iwakura Tomomi and included such luminaries as Ito Hirobumi and Kido Takayoshi. These emissaries journeyed to the United States and eleven European countries, making thorough investigations into each country's politics, military affairs, trade and industry, education, and culture. Their reports, which helped Japan emerge as a modern industrial nation, constitute an indispensable documentary resource. Volume I covers the departure of the Embassy from Yokohama, the Pacific crossing, the arrival in San Francisco, the wintry rail journey across the United States, the unexpectedly long stay in Washington, D.C., and the departure from Boston.
