Japanese retailers are vying to cash in on the country's drive for energy-savings this winter season by offering a new selection of thermal underwear. Major clothing retailer Uniqlo is expanding its lineup of popular winter underwear to include products for toddlers. Retail chain Seiyu has developed a new line of thermal underwear at a 20 percent discount to last year. Stores are expecting higher demand for winter underwear as consumers prepare to turn down the heat in the face of power rate hikes.
