With the relentless heat showing no signs of abating, daytime temperatures are expected to soar above 40 degrees C, marking the first time this year that Japan will see over 200 locations experience extreme heat, reported Xinhua news agency.

On Sunday, the mercury in Tokyo is forecasted to reach 36 degrees C, as many regions from Tokai to Kanto could see temperatures exceeding body temperature, according to the JMA.

With temperatures in Maebashi and Chichibu predicted to hit 39 degrees C, those in some inland areas of Kanto would potentially reach 40 degrees C.

The heatwave has led to a record number of heatstroke cases in many parts of the country.

Two elderly residents in the prefectures of Ehime and Tokushima were reported dead over heatstroke, while Tokyo reported 119 heat-related emergency cases on the same day, including three severe cases among the elderly.

Authorities urged residents, especially elderly people and children, to use air conditioners appropriately, stay hydrated even when not thirsty, and avoid unnecessary outings and exercise.
