TOKYO, Dec. 4 (Xinhua) -- Tokyo stocks ended higher on Thursday, boosted by shares related to artificial intelligence (AI) amid optimism for further growth.
The 225-issue Nikkei Stock Average ended up 1,163.74 points, or 2.33 percent, from Wednesday at 51,028.42. The broader Topix index finished 63.89 points, or 1.92 percent, higher at 3,398.21.
Stocks of companies related to AI-powered robotics technology rallied, with machinery maker Fanuc soaring 13.0 percent to 5,953 yen and robotics firm Yaskawa Electric climbing 11.4 percent to 4,769 yen.
On the top-tier Prime Market, the main gainers were wholesale trade, information and communication, and securities house issues.
The yield on the benchmark 10-year Japanese government bond briefly rose to 1.935 percent, its highest level since July 2007, amid speculation that the Bank of Japan may raise interest rates at its policy meeting later this month.
Rising yields are likely to fuel worries that higher housing loans for households and borrowing costs for companies could adversely impact the economy. ■
