Tokyo stocks closed higher Monday as investors cheered data showing that business sentiment had improved while the yen remaining comparatively weak added support, but the ruling Liberal Democratic Party's historic defeat in the the Tokyo assembly election saw gains capped.

The 225-issue Nikkei Stock Average added 22.37 points, or 0.11 percent, from Friday to close the day at 20,055.80.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, gained 2.51 points, or 0.16 percent, to close at 1,614.41.

Iron and steel, oil and coal product, and nonferrous metal-linked stocks comprised those that gained the most by the close of play, and advancing issues outpaced declining ones by 1,117 to 767 on the First Section.

Trading volume on the main section on Monday came to 1,601.09 million shares, dropping from Friday's volume of 1,968.97 million shares.

The turnover on the first trading day of the week totaled 2,050.9 billion yen (18.22 billion U.S. dollars).
