A Comparative Study of the Formation and Transformation of Korean and Japanese Estuarine Port Cities: The Cases of Gunsan and Niigata This study comparatively analyzes the formation and development of estuary port cities, focusing on Gunsan, Korea, and Niigata, Japan.
By examining regional cities sharing unique estuarine conditions, this research identifies the structural mechanisms of urban development
across four dimensions: geography, history, economy, and the contemporary environment. Geographically, Gunsan and Niigata leveraged their locations at the estuaries of the Geum and Shinano Rivers and their productive hinterlands—the Honam and Echigo Plains—to grow into logistical nodes. Economically, both cities evolved from pre-modern distribution hubs (the Gunsan-chang system and the Kitamaebune route) into modern national logistics gateways by integrating river, rail, and maritime networks. Historically, while Gunsan underwent rapid reorganization into a port-centered city upon its modern opening, Niigata experienced gradual development rooted in pre-modern commercial traditions.
Despite these differences in historical continuity, both share the structural similarity of expanding urban functions based on estuarine geography. Currently, however, both cities face shared crises of population decline and industrial restructuring as traditional port-centered logistics are marginalized by modern land-based transportation. In conclusion, the evolution of Gunsan and Niigata demonstrates that estuary port cities are shaped by a synthesis of geographical location, logistical structures, and historical conditions. By confirming the multi-layered similarities between these cities across various sectors, this study provides a new comparative model for understanding the structural transformation of regional port cities.
