TOKYO, Feb. 19 (Xinhua) -- Tokyo stocks ended higher on Thursday, led by some heavyweight technology shares, while a weaker yen helped lift some exporters.
The benchmark Nikkei stock index, the 225-issue Nikkei Stock Average, ended up 323.99 points, or 0.57 percent, from Wednesday at 57,467.83.
The broader Topix index, meanwhile, finished 44.84 points, or 1.18 percent, higher at 3,852.09.
The U.S. dollar strengthened to the lower 155 yen level in Tokyo. The yen's weakness lifted some export-oriented issues, including Toyota Motor.
On the stock market, Tokyo Electron and Shin-Etsu Chemical were notable gainers as their U.S. counterparts moved higher overnight on Wall Street due to hopes for an expansion of the artificial intelligence market, analysts said. ■
