NTT DoCoMo to close its offices in Tokyo on Mondays and Tuesdays to save electricity

The Japanese mobile phone firm NTT DoCoMo plans to close its offices in Tokyo and its vicinity on Mondays and Tuesdays from July to September as part of its energy saving efforts. NTT DoCoMo will instead open the offices in the region on weekends, as the electricity supply-demand balance is expected to tighten after power generation capacity was damaged due to the March 11 earthquake-tsunami disaster. In a similar bid to cut weekday electricity consumption, the Japan Automobile Manufacturers Association has decided to close the member firms’ plants on Thursdays and Fridays and open them on Saturdays and Sundays.

NTT Docomo’s parent, Nippon Telegraph and Telephone, is considering cutting summer electricity consumption of the entire NTT group by more than 30%. The NTT Docomo holiday system change is designed for 3,000 to 4,000 workers, excluding cell phone shop and call center workers who usually work on the weekend.
