Coping with Heatstroke and Extreme Heat in Japan
July 29, 2026
Japanese summers can be incredibly hot, posing risks for heatstroke. This article explains what heatstroke is, its origin, its impact, how foreigners can respond, and important manners and precautions.
■ What is Heatstroke
Heatstroke occurs when prolonged exposure to high temperatures and humidity disrupts the body's ability to regulate temperature, leading to health issues. It is a common problem in Japan's humid summer, with symptoms ranging from mild to severe.
■ When and Where
Heatstroke is prevalent throughout Japan from June to September, particularly in July and August, though the specifics may vary by region.
■ Impact on Daily Life
During extremely hot weather, public transport and tourist spots may become crowded. To prevent heatstroke, people often carry cold drinks and umbrellas. Air-conditioned commercial facilities are also likely to see more visitors.
■ How Foreigners Can Cope
Foreign tourists are advised to take rest breaks in air-conditioned areas and stay well-hydrated. Avoid going out during peak sunlight hours or use sunglasses and hats to protect against direct sunlight.
■ Manners and Precautions
Avoid setting air conditioners too low in public spaces. Plan purchases of drinks and daily items to avoid peak times and crowds, and try to travel outside of rush hours to ensure a more comfortable experience.
