This article examines the multifaceted role of urban markets in post-War Okinawan society, arguing that these commercial spaces have been functioning as critical nodes of community cohesion, cultural transmission and collective resilience that extend far beyond their economic purpose. Through an interdisciplinary lens incorporating ethnographic methodology, oral history, archival research and visual and sound mapping of the communicative ecology of machigwā (small markets) in the Okinawan capital, Naha, this study demonstrates how Okinawan markets exemplify the concept of ‘social infrastructure’—physical spaces that facilitate social interaction and community building. The research draws on these methods to trace the evolution of the machigwā from its establishment as black market in the post-war era through contemporary challenges posed by tourism commodification, the COVID-19 pandemic, generational shifts and urban development. The findings reveal that machigwā has historically operated and continues to do so as embedded social ecosystems where economic transactions have been mediated by gender, kinship networks, reciprocal relationships and shared historical trauma. However, these communal functions are facing significant threats from tourism-driven spatial reorganisation and disrupted intergenerational knowledge transfer that risk bypassing community needs. Despite these challenges, the machigwā’s evolution shows that it has the capacity to maintain aspects of its social infrastructure while adapting to contemporary pressures, at least for now.
