In this study, we carried out future projections of the thermal environment in the summer of the 2050s in the Nagoya metropolitan area by introducing scenarios of urban planning/structure in addition to the effect of future global warming, and we investigated the impacts of future urban planning/structure on the thermal environment. Here, three urban planning/structure models (centralized and decentralized models, and a plan to avoid tsunami damage) were introduced. Furthermore, for the future urban planning/structure models, we considered the reduction of urban areas due to the predicted decrease in population, and investigated the change of the thermal environment with the reduction of urban areas.
