— Japan began imposing energy restrictions on companies, shopping malls and other major electricity users Friday to cope with power shortages caused by the loss of a tsunami-hit nuclear power plant.
Big factories, office buildings, universities and department stores in the Tokyo area must use 15 percent less electricity than a year ago. Electricity is in short supply due to the shutdown of the Fukushima Dai-ichi plant hit by the massive March 11 earthquake and tsunami.
