Japan is facing record-breaking heat, with temperatures hitting 41.8°C, sparking health emergencies and threatening the country’s rice harvest.

The government has urged residents to stay indoors and announced emergency support to combat rising health risks and agricultural damage.

More than 53,000 people have already been hospitalised due to heat stroke this summer, according to authorities.

The extreme heat comes as average temperatures in Japan continue to rise for the third consecutive summer, coupled with severe drought in the northeast.

Authorities are particularly concerned about the rice harvest, as a surge in stink bugs threatens crops in key growing areas.

In response, the Japanese government has unveiled a new rice production policy aimed at avoiding future shortages.

"We need to act with speed and a sense of crisis," said Farm Minister Shinjiro Koizumi, promising measures to support pest control and drought management.

Last year’s heatwave damaged rice quality and, combined with poor supply planning, caused sharp price increases and a national food scare.

Officials hope prompt action this year will prevent a repeat of that crisis.
