TOKYO, June 1 (Xinhua) -- Tokyo stocks closed mixed Friday as easing concerns about Italy's political situation and a softer yen encouraged buying, but selling was promoted by concerns the United States will impose tariffs on steel and aluminum imports from the European Union, Canada and Mexico.

The 225-issue Nikkei Stock Average lost 30.47 points, or 0.14 percent, from Thursday to close the day at 22,171.35.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, edged up 1.72 points, or 0.1 percent, to finish at 1,749.17.

Electric power and gas, and food issues comprised notable decliners, while transportation equipment, oil and coal product, and mining-oriented issues led those that gained the most by the close of play.?
