TOKYO (AFP) - In their stuffy grey suits, starched collars and boring ties, Japans famed salarymen could hardly be accused of being at the cutting edge of sartorial innovation. Now these warriors of the Japanese economy are being asked to ditch their sweaty battle attire for cooler T-shirts and trainers from Wednesday in a bid to turn down air conditioning and reduce electricity consumption following the March 11 disasters. Since 2005 the government has encouraged office workers to cast off ties and jackets in the stifling summer months as part of a pledge to cut greenhouse gases by six percent as part of the Kyoto protocol. Environment Minister Ryu Matsumoto has announced a souped-up Super Cool Biz campaign this year to relieve the pressure on the electricity grid after the March 11 quake-tsunami and ensuing nuclear emergency. A fashion show organised by the government in a chilly Tokyo on Wednesday to highlight the campaign caused a stir on the Twitter microblogging site, with mixed reactions to the launch. When the earthquake struck the northeast coast of Japan, the crisis at the crippled Fukushima nuclear plant and other power stations triggered a drop in energy output. Electricity companies have been scheduling power cuts and businesses have been cutting usage by dimming lights and turning off heated toilet seats, as well as installing low-energy bulbs. Super Cool Biz encourages businesses and government departments to set the dial on air conditioners to 28 degrees Celsius (82 degrees Fahrenheit). Employees in the ministry will set an example to corporate Japan by wearing cotton trousers, T-shirts and even loud Aloha shirts.
