This article reviews recent scholarship on Asian mobility, focusing on the influence of the prewar Japanese empire on the mobility (and immobility) of people, goods, and ideas in Asia today. Prewar Japanese technicians, engineers, and politicians built highways, aviation systems, electricity grids, and communication networks seeking to create new levels of transnational mobility and human integration. Nonetheless, unlike Europe, this infrastructure failed to stimulate movements toward Asian integration. Mobility scholars, east and west, should be interested in the divergences between Asia and Europe in dealing with the construction and use of emerging transnational infrastructures since World War II.
