Japan is asking Tokyo residents to conserve power, with unusually hot weather stretching the city’s grid as fears increase that the heat could last for longer.

Electricity supply in the capital will continue to be tight Tuesday after households, businesses and utilities took steps Monday to help avoid any blackouts.  The country’s government extended a power supply advisory for Tokyo which calls for curbs on consumption.
