Heatstroke alerts have been issued in some areas of the country for Tuesday. Cases of hospitalisation have risen.

Temperatures in Tokyo hit 35.1 degrees Celsius by 1 pm local time. This has broken nearly 150-year record of 35 C, set in 1875. Japan Meteorological Agency forecast highs of 36 C for Tokyo on Thursday and 35 C on Friday.

Authorities have asked consumers in the Tokyo area to conserve electricity to avoid a looming power cut.

The interior of Ministry of Economy, Trade and Industry (METI) building can be seen dimly lit to save electricity during daytime as Japanese government issues warning over possible power crunch in Tokyo.

Heat wave and looming power cuts also have the potential of having political ramifications. Japanes Prime Minister Fumio Kishida's party is expected to do well. But public anger has a potential to hurt prospects.
