This paper deals with literary representations of memories of world war II in three novels, including Taiwanese writer Song Ze-Lai's “The Last War”(1976), Chen Ying-Zhen's “The Zhong-Xiao Park”(2001), and Okinawa writer Medoruma Shun's “Droplet”(1997), exploring how Taiwanese and Okinawa writers intervene in the heated debates on war and postwar responsibility in East Asia. Through divergent writings of East Asian war memories and memory wars, how do these novels demonstrate the historical predicaments of Taiwan and Okinawa? How do the issues of war memories intersect and entangle with postwar national identities? Locating three literary texts in historical contexts, this paper analyzes the condition in which war memories of Taiwanese Japanese-soldiers and Okinawa inhabitants are in danger of being incorporated into Japan’s national war narrative, as a consequence of emphasizing their contributions “fighting as Japanese” in the debates of war and postwar responsibility. This paper argues that as ambivalent and confused historical subjects, the very existence of Taiwanese Japanese-soldiers and Okinawa inhabitants have disturbed the singular alignment of body, nationality, and war, and therefore problematize their bodies “fighting as Japanese,” challenging national war narratives and politics of war memories in East Asia. Furthermore, the historical dynamics of these “non-state” bodies also connect to the possibility for Taiwanese Japanese-soldiers and Okinawa inhabitants to cross national demarcations and share historical experiences and traumatic memories of war with other minority people, and work together to resist wartime and postwar violence in the name of nationalism.
