Urban Modernities reconsiders Japanese colonialism in Korea and Taiwan through a relational study of modernist literature and urban aesthetics from the late colonial period. By charting intra-Asian and transregional circulations of writers, ideas, and texts, it reevaluates the dominant narrative in current scholarship that presents Korea and Taiwan as having vastly different responses to and experiences of Japanese colonialism. By comparing representations of various colonial spaces ranging from the nation, the streets, department stores, and print spaces to underscore the shared experiences of the quotidian and the poetic, Jina E. Kim shows how the culture of urban modernity enlivened networks of connections between the colonies and destabilized the metropole-colony relationship, thus also contributing to the broader formation of global modernism.
