As Japan’s east heats up, citizens are encouraged to save power

JAPAN: Temperatures in eastern Japan have been at their hottest since records began, forcing the government to advise residents to conserve electricity as much as possible, while keeping air conditioners on in order to remain safe.

There will be a scorching weekend for those who live in and around Tokyo, as temperatures rose above 35 degrees Celsius for the seventh straight day on Friday (Jul 1). On Monday, milder temperatures and perhaps rain are in the forecast, which could provide welcome reprieve.

However, although energy supplies are tight and prices are high, authorities did not issue a warning about a possible power shortage on Friday for the first time this week; this fuels government demands for restarting more nuclear reactors that have been shut down since the Fukushima disaster in March 2011.

Isesaki, Japan’s hottest city so far this year, had a temperature of 40.3 degrees Celsius, while numerous other towns north of Tokyo recorded temperatures of 40.1 and 40 degrees Celsius. The temperature in Tokyo’s central business district rose to 37 degrees Celsius.

Similar temperatures are common in Japan, but rarely so early in the year. The June heat wave was the most extreme on record, dating back to 1871.
