Avoid heatstroke while traveling in Japan

As summer is starting in Japan, both the temperature and humidity are on the rise. Though they might not yet be at their peak, it is important to know that heatstrokes can occur at any time, especially when the body is struggling to adjust to the rapidly raising temperature. Extra caution is advisable if you are traveling from areas where heatstrokes are less common. Please make sure to follow the tips written down below and keep yourself safe. 

1. Avoid high temperatures and humidity. 

  • When inside a building, lower the room temperature with air conditioning or other devices.
  • Don’t overexert yourself when the temperature is high.
  • Wear breathable clothing.
  • Be especially careful on days when the temperature suddenly rises.

2. Drink plenty of water

  • Drink water even before you start to feel thirsty.
  • If you are sweating a lot, be sure to take in plenty of sodium. 

3. Rest

  • Take frequent breaks and avoid intense exercise.

4. Take care of your health.

  • Check the weather forecast and heat index (WBGT) before heading out.
  • Try to eat a balanced diet in order to replenish nutrients, get enough sleep and exercise moderately.

Heatstroke alert

"Heatstroke alerts" are issued by the Ministry of Environment and the Japan Meteorological Agency when the predicted risk of heatstroke is extremely high. By warning people of the dangerous temperature and encouraging them to take preventive measures, it is possible to lower their chances of heatstroke.

If the heat index (WBGT) is forecast to be 33 or higher anywhere in the prefecture’s area, a heatstroke alert is issued at 5:00 p.m. on the day before and at 5:00 a.m. on the day with the dangerously high temperature.

You can access the heatstroke alert from the link below:

Special heatstroke alert

Starting in 2024, a “special heatstroke alert” will be issued when unprecedented, widespread and dangerously high temperatures are expected to occur.

If the heat index (WBGT) is forecast to reach 35 or higher, the alert will be issued at 2 p.m. on the day before in each prefecture.

You can access the special heatstroke alert from the link below:
