Social Background: Rising Heatstroke Cases Make Sports Heat Management Urgent Due to recent extreme heat, the number of emergency transports due to heatstroke is on the rise. According to a report by the Ministry of Internal Affairs and Communications, there were 100,510 emergency transports in 2025, the highest since records began (*1). Furthermore, the Japan Meteorological Agency has announced that the summer of 2026 is 'highly likely to be hotter than average,' suggesting another period of severe heat (*2). In addition, heatstroke incidents among young people in school and club activities have shown a long-term upward trend. Data from the Japan Sport Council's 'Disaster Benefit' shows that medical benefit claims for heatstroke among students rose from approximately 300 per year in the 1980s and 90s to 4,000 per year in the 2010s. Most of these occur during physical activities, and the number remained high at over 3,000 in 2023 (*3). This situation presents a common risk for all sports practitioners, from competitive athletes to casual enthusiasts, making effective heat management during exercise increasingly important.

Given these trends, there is a growing demand in the sports world for 'easy-to-use heat management items.' *1) Ministry of Internal Affairs and Communications, 'Emergency Transport Status Due to Heatstroke (May-September 2025)', p.2, October 29, 2025. *2) Japan Meteorological Agency.
