TOKYO, Feb. 14 (Xinhua) -- Tokyo stocks ended essentially flat Thursday as buying supported by the yen's retreat against the U.S. dollar was offset by investors opting to lock in gains following the market's recent rise.

The 225-issue Nikkei Stock Average shed 4.77 points, or 0.02 percent, from Wednesday to close the day at 21,139.71.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile edged down 0.48 points, or 0.03 percent, to finish at 1,589.81.

Oil and coal product, pulp and paper, and construction issues led notable gainers, while mining, rubber product and services issues comprised those that declined the most by the close of play.
