Japanese author Shimao Toshio (1917–1986) exemplifies the postwar tensions between cultural production and debates on national identity in Japan. His Southern Island essays explore the relationship between Japanese and Ryūkyū cultures, presenting peripheral regions as vital to Japan’s cultural landscape. While his works attracted the attention of intellectuals such as Okamoto Keitoku and Arakawa Akira and became part of broader discussions on Okinawan culture and the anti-reversion movement of the 1960s and 1970s, they were also criticized for essentialist depictions that appeared to affirm Japan’s claims over the Ryūkyū Islands. This presentation examines Shimao’s conception of culture and identity within the discourse of postwar cultural homogeneity, employing a combination of quantitative text analysis using KH Coder and qualitative interpretation to reveal how his writings simultaneously reflect and question dominant narratives of Japanese identity.
