Science, technology, and medicine all contributed to the emerging modern Japanese empire and conditioned key elements of post-war development. As the only emerging non-Western country that was a colonial power in its own right, Japan utilized these fields not only to define itself as racially different from other Asian countries and thus justify its imperialist activities, but also to position itself within the civilized and enlightened world with the advantages of modern science, technologies, and medicine. This book explores the ways in which scientists, engineers and physicians worked directly and indirectly to support the creation of a new Japanese empire, focussing on the eve of World War I and linking their efforts to later post-war developments. By claiming status as a modern, internationally-engaged country, the Japanese government was faced with having to control pathogens that might otherwise not have threatened the nation. Through the use of traditional and innovative techniques, this volume shows how the government was able to fulfil the state’s responsibility to protect society to varying degrees.
