The Courteous Power seeks to provide a nuanced view of the current relationship between Japan and Southeast Asia. Much of the current scholarship on East–Southeast Asian engagement has focused on the multidimensional chess game playing out between China and Japan, as the dominant post-imperialist powers. Alternatively, there has been renewed attention on ASEAN and other Southeast Asian–centered initiatives, explicitly minimizing the influence of East Asia in the region. Given the urgency of understanding the careful balance in the Indo-Pacific region, this volume brings together scholars to examine the history and current engagement from a variety of perspectives, ranging from economic and political to cultural and technological, while also focusing more clearly on the specific relationship between the region and Japan.
