• This research identifies the dates that sports days in Japanese public elementary schools were held and evaluates the risk of heat disorders on those days. The dates of the sports days were determined from websites published by the schools, and data of wet-bulb globe temperature (WBGT) on sports days was obtained from the Ministry of the Environment. The risk of heat disorders on the sports days was assessed using the guidelines prescribed by the Japanese Sports Association. In all, 54.3% of elementary schools held their sports days during the spring, and the remaining 45.7% held theirs in autumn. On average, the first and last dates for sports days were May 16 and June 11 in the spring and September 11 and October 17 in the autumn. In Okinawa Prefecture, 99.0% of elementary schools held their sports days in hot weather, in which the risk of heat disorders was “Warning” and higher, but the number of heat disorder cases was as small as 5 cases. This might be explained by a heat acclimatization and appropriate measures for prevention of heat disorders. Determining the periods of higher risk of heat disorders for sports days based on daily maximum WBGTs will contribute to the prevention of heat disorders.
