Japan urges heatstroke prevention for outdoor leisure and workplaces as summer heat rises

A 2026 survey by Taisho Pharmaceutical of 484 Japanese adults aged 20‑60 found that 42 % had experienced or witnessed heat‑stroke‑like symptoms during outdoor summer activities. The most common precautions reported were carrying water or tea, wearing hats and using sunscreen, while fewer participants mentioned oral rehydration solutions (87 respondents) or ice‑slurry drinks (80 respondents). The study highlighted that while basic hydration and sun protection are widely adopted, pre‑activity health checks and electrolyte replacement remain under‑utilised.

In parallel, the July issue of *BCP Leaders* examines workplace heat‑stroke prevention following the June 2025 legal mandate in Japan. Companies such as Aeon, Yomiuri Land and Toda Construction are cited for measures including on‑site health‑monitoring systems, expanded cool‑down areas, specialised cooling workwear and clear reporting procedures. Experts stress the importance of organizational systems that encourage early symptom reporting, proper monitoring equipment and integration of heat‑stroke management into business continuity planning.
