Katherine BiekThe Japanese government classified an "unprecedented" heatwave that's sweeping the country as a natural disaster Tuesday.
The country's Fire and Disaster Management Agency said that since the beginning of the month, the extreme heat has killed at least 80 people and sent more than 35,000 to the hospital.
On Monday, temperatures in the city of Kumagaya — which is outside of Tokyo — hit 106 degrees Fahrenheit. That's reportedly the highest temperature ever recorded in Japan since officials started keeping track.
The Japan Meteorological Agency warned high temperatures will continue into early August. Its advising people to stay out of direct sunlight and drink plenty of water.
As the heat continues, a government spokesman said officials might extend the summer holiday for students since the majority of public schools do not have air conditioning.
