Japanese stocks rose Thursday morning as the yen's fall against the dollar helped lift exporters such as carmakers and electronics, according to dpa. The benchmark Nikkei 225 Stock Average gained 27.69 points, or 0.32 per cent, to trade at 8,669.54 at the end of the morning session at 11:30 am (0230 GMT). The broader-based Topix index was up 5.03 points, or 0.69 per cent, at 734.81. Export-linked stocks such as carmakers and electronic advanced in the morning as the yen declined against the dollar. A weaker yen makes Japanese goods less expensive overseas and improves repatriated earnings. Toyota Motor Corp and Nissan Motor Co were also bolstered by robust sales data in the United States. Shares in Toyota rose 3.33 per cent and Nissan climbed 2.18 per cent after sales in July jumped 26.1 per cent and 16.2 per cent, respectively, according to US industry research firm Autodata Corp. Sony Corp surged 5.21 per cent, Sharp Corp rose 4.15 per cent and Canon Inc gained 1.01 per cent. On currency markets at 11:30 am in Tokyo, the dollar traded at 78.48-52 yen, up from Wednesday's 5 pm quote of 78.17-19 yen. The euro quoted at 96.09-14 yen, down from 96.28-32 yen late Wednesday, and at 1.2240-2244 dollars, down from 1.2317-2319 dollars.
