2 – 3 minutesTokyo experienced its hottest July day on record Tuesday, as temperatures soared past 39°C (102°F), prompting government officials to urge residents to stay indoors and limit physical activity. Hospitals across the capital reported a surge in heatstroke-related emergencies, especially among the elderly.
The Meteorological Agency said the extreme heatwave is part of a broader pattern linked to El Niño, which continues to influence global weather systems. Officials have extended a heat alert through the weekend and warned that conditions could worsen unless measures are taken.
“We are advising people to avoid going out during the hottest part of the day, drink plenty of water, and use air conditioning when possible,” said Health Minister Ayaka Nomura during a press briefing. “This is not just uncomfortable — it’s dangerous.”
Local schools cancelled outdoor activities, and some companies shifted to remote work to protect employees. Meanwhile, convenience stores reported spikes in sales of bottled water, sports drinks, and cooling pads.
Experts warn that such heatwaves may become more frequent as climate change accelerates. “Urban areas like Tokyo are especially vulnerable because of the heat island effect,” said Dr. Koji Watanabe, a climate scientist at the University of Tokyo.
As the city braces for more sweltering days ahead, Tokyo residents are adjusting routines, hoping relief comes soon.
