| Outline of Final Research Achievements |
The relationship between heat and cold mortalities and meteorological factors in Japan was studied using vital statistics data for eighteen years (1999 to 2016). Statistical analyses were made for spatial variability according to prefectures and local municipalities, and temporal variations on annual, seasonal, and daily scales. It was found that heat and cold mortalities tend to be higher under higher and lower temperatures, respectively, and depend on ages, seasons, and regions. There are some features implying the effect of acclimatization to heat mortality. Additionally, heat and cold mortalities are found to be high in local municipalities with low mean income, implying the influence of social factors.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により，日本の熱中症・低温による死亡と気象要素との関係について一連の統計事実が得られ，また，熱中症・低温死亡に対する社会的要因の寄与が検証された．これらの知見は，これまで経験的あるいは定性的な理解にとどまっていた熱中症被害の気候学的特性を統計的に裏づけ，併せて低温死亡の実態を明るみにするものであり，熱中症や低温の被害を抑止していく上での基礎資料になることが期待できる．
