Tokyo stocks closed higher Monday as investors took heart from Wall Street's rally at the end of last week in early trade, while the yen dipping against the U.S. dollar added broad support and gave exporters a boost later on.

The 225-issue Nikkei Stock Average gained 124.49 points, or 0.62 percent, from Friday to close the day at 20,067.75.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, added 10.03 points, or 0.63 percent, to finish at 1,606.07.

Metal product, service and pharmaceutical-linked issues comprised those that gained the most by the close of play, and advancing issues outpaced declining ones by 1,414 to 508 on the First Section.

Trading volume on the main section on Monday came to 1,484.69 million shares, dropping from Friday's volume of 2,285.56 million shares.

The turnover on the first trading day of the week totaled 1,986.7 billion yen (17.89 billion U.S. dollars).
