Prime Minister Taro Aso and other ministers promoted the annual Cool Biz energy-saving campaign Tuesday by donning Okinawan "kariyushi" light wear at their regular Cabinet meeting.
Commenting on Aso, who appeared in a white long-sleeved kariyushi, Seiko Noda, state minister in charge of consumer affairs, told reporters after the meeting, "The prime minister wore it very neatly."
The Cool Biz push started in 2005.
It runs from early June to the end of September with government officials wearing light clothing and no ties or jackets at work so air conditioners can be kept at higher temperatures and thus emit less carbon dioxide.
Aso's kariyushi was a present from Okinawa Gov. Hirokazu Nakaima.
