Takeshi Hamashita, arguably Asia’s premier historian of the longue durée, has been instrumental in opening a new field of inquiry in Chinese, East Asian, and world historical research. The stones that he has cast in the pond of historical interpretation have sent ripples throughout Japanese, Chinese, and international scholarship. Central to his approach has been the attempt to redefine the evolving relationships between the East Asia regional system and the world economy from the sixteenth century to the present. His research has led him to reconceptualize the position of China first in the context of an East Asian regional order and subsequently within the framework of a wider Euro-American-Asian trade and financial order that was long gestating within, and indeed contributing to the shape of, the world market.
