The chief motivation of this study is to put forward a transdisciplinary, customized, and broadly applicable blueprint for understanding future climate change impacts at regional to national scales and further advancing adaptation planning in Japan. Effective adaptation planning and decision-making call for reliable, comprehensive, and cross-cutting climate-related information. In light of this, we present a reproducible methodological framework that scales and delineates diverse climate change impacts based on spatial analytical technology. Using the K-means multivariate clustering algorithm, seven spatial indicators that reflect national and local interests across different sectors were synthesized to recognize the homogeneous impact zones (HIZs) and produce the analogous impact maps in 2100 under different future scenarios. Results show that each analogous impact map comprises nine HIZs, albeit to varying degrees of diverse impacts. The changes in climatic parameters prominently drove the spatial stratification and configuration of analogous impact maps. Findings from this study can offer a reference for the potential climate-related interventions and options towards a comprehensive, cross-sectoral adaptation pathway.
