The government will launch its Cool Biz campaign again this year on May 1, the same as last year. Prior to 2011, the campaign began on June 1, but it was brought forward by a month last year in a bid to conserve electricity after worries that there would be a power shortage following the March 11 disaster.
The campaign will last until Oct 31, according to the Environment Ministry. During this time, employees are encouraged to ditch their suits and ties for open-necked, short-sleeved shirts.
