The Nikkei share average notched up its biggest daily gain in two weeks on Thursday as investors took a rally in US stocks as a signal to buy, shrugging off the yen's rise to its highest level in nearly five years. The Nikkei jumped 1.75 percent after bargain hunters saw a 200-point tumble in the previous two sessions following weak Japanese industrial output data as an opportunity to snap up battered exporters such as Canon Inc.
Shares in the camera and copier maker rose 2.36 percent to 5,200 yen, snapping back from a 1.6 percent drop on Wednesday.

The Nikkei rose 188.82 points to 10,973.07, its biggest daily gain since November 15. The broader TOPIX index gained 1.66 percent to 1,105.38.
