Your Guide to Surviving Summer in Japan

Avoid getting heatstroke this summer season!

Summer in Japan is known as very humid, that’s why you may feel hotter although the temperature is lower than the summer in the Philippines. 

The ministries and Japan Weather Association call on people to be careful of heatstroke from June to September. It is caused by certain climate (high temperature, high humidity, no wind, strong sunlight), health condition (diabetes, mental disorder,
malnutrition, hangover, lack of sleep, dehydration), and physical condition (hard exercise, outside work, not drinking water for long hours). As a result, the body can’t release the heat inside effectively.

If you see these symptoms, better to take a rest in the shade. If it is the last two, it is recommended you go to hospital.
