Tokyo stocks closed lower Wednesday as weak U.S. consumer confidence data coupled with the yen's appreciation against the U.S. dollar saw investors in a circumspect mood.

The 225-issue Nikkei Stock Average lost 27.28 points, or 0.14 percent, from Tuesday to end the day at 19,650.57.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, dropped 4.30 points, or 0.27 percent, to finish at 1,568.37.

Oil and coal product, bank and rubber product-related stocks comprised those that declined the most by the end of play, and declining issues outpaced advancing ones by 1,282 to 622, on the First Section.

Trading volume on the main section on Wednesday came to 2,018.98 million shares, jumping from Tuesday's volume of 1,326.03 million shares.

The turnover on the third trading day of the week totaled 3,017.6 billion yen (27.19 billion U.S. dollars).
