Extensive modeling evidence indicates the relationship between projected temperature changes and the expected increase in heat-related mortality and morbidity. While the link between temperature and climate-sensitive health outcomes may appear straightforward, it is more complex, as fatal and non-fatal impacts differ by disease, age, and sex. In light of global warming and population aging, few studies have reported the integrated impacts of a warmer climate in shrinking and aging societies such as Japan. By simultaneously estimating current temperature-related mortality and morbidity by cause, age, and sex, and projecting future impacts under population change and adaptation scenarios in Japan, important implications emerge for policymakers: protecting vulnerable populations, developing targeted mitigation and adaptation policies, and preparing for additional heat-related morbidity requiring greater medical resources and potential expansion of secondary healthcare infrastructure.
