Tokyo stocks rise 0.77% by break

Tokyo shares rose 0.77 percent on Tuesday morning in largely directionless trade with few solid cues and a weaker dollar capping the market's gains.

The benchmark Nikkei 225 index added 112.23 points to 14,770.27 by the break, reversing a 0.70 percent decline at the open, while the Topix index of all first-section shares was 0.40 percent, or 4.87 points, higher to 1,221.40.
