The Rise of Sun Umbrellas: A Key Strategy Against Heatstroke in Japan

In recent years, with the Japan Meteorological Agency designating days with temperatures exceeding 40℃ as "extreme heat days," the consciousness surrounding heat management has significantly escalated. Therefore, the significance of sun umbrellas as a countermeasure against heatstroke has garnered renewed attention. Waterfront Co., Ltd., a company based in Shibuya, Tokyo, has conducted a comprehensive survey targeting a diverse demographic of 1,000 individuals aged 20 to 60 across the nation to explore the changing perceptions and motives regarding sun umbrellas.
