Hiroshima and Emigration
 In the 1880s, a great number of people moved from Hiroshima to the Hanshin (Osaka-Kobe) and Kyushu regions to work away from home due to a number of economic factors, including scarce employment in the region. Furthermore, a lot of people immigrated to Hawaii in search of better incomes.
 Since the first immigrant ship City of Tokio departed for Hawaii in 1885 (Meiji 18), so many people have left Hiroshima to countries such as the United States of America, Canada, Peru, and Brazil that Hiroshima became the prefecture with the most emigrants in Japan.
