Tokyo shares added 0.92 percent Monday morning thanks to a weakening yen and as traders followed another record finish for the Dow on Wall Street.
The benchmark Nikkei 225 index added 112.93 points to 12,396.55, while the Topix index of all first section shares jumped 2.15 percent, or 21.91 points, to 1,042.41.
The market was tipped to trend higher on continued weakness of the yen against the dollar, particularly after US jobs data came in far better than expected, analysts said.

Nishi estimated the Nikkei would hover between 12,300 and 12,500, but added that the market appeared "technically overbought in the short-term".
