International Journal of Climatology, Volume 45, Issue 8, 30 June 2025.From 1980 to 2020, it was found that not only summer heat stress, in terms of the Universal Thermal Climate Index (UTCI), but also winter cold stress has been worsening throughout Japan. Daily maximum UTCI values above which heat stroke cases rapidly increased tend to be relatively low in northern cities.
