The incidence of heat stroke due to the deterioration of the heat environment increased and has been also observed in the emergency transport data. Risks may change due to changes in indoor and outdoor lifestyles of children and the elderly people, and there is concern that vulnerability may increase. In order to study the improvement measures based on the current situation of these problems, we investigate the trend of the heat stroke incidence rate and analyze the relationship with the geographical conditions in the region between attributes such as age of people and heat stroke. Then, in this study, based on the statistical data on heat stroke that we obtained independently, we used data for each small zone in 7 cities of Kansai region. Furthermore, we clustered each feature and evaluated the relationship with the demographic and geographical features of the small zone using the emergency transport data for heat stroke. We also evaluated what preventive measures should be taken before heat stroke in areas where there is a large number of emergency deliveries due to heat stroke.
