Tokyo stocks ended mixed Monday, with the benchmark Nikkei stock index extending its losing streak to five straight days as the yen appreciated against the U.S. dollar amid ongoing geopolitical concerns.

The 225-issue Nikkei Stock Average edged down 9.29 points, or 0.05 percent, from Monday to close the day at 19,383.84.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, added 0.93 point, or 0.06 percent, to finish at 1,596.12.

Land transportation, food, and construction-linked issues comprised the day's notable decliners, and rising issues outpaced falling ones by 966 to 919 on the First Section.

Brokers here said the Nikkei lost ground as investors remained in a circumspect mood amid geopolitical tensions on the Korean Peninsula, particularly in light of the recent start of annual joint military exercises in the region between the United States and South Korea.

Traders here also noted, however, that losses were trimmed by investors buying on dips and seeking out bargains following the market's recent run of closing lows.

On the main section on Tuesday, 1,314.91 million shares changed hands, dropping from Monday's volume of 1,406.90 million shares.

The turnover on the second trading day of the week came to 1,714.2 billion yen (15.66 billion U.S. dollars).
