Tokyo's benchmark stock index rose Friday morning though investors remained cautious ahead of U.S. job data due out later in the day. The dollar was down against the Japanese yen and the euro. The Nikkei Stock Average of 225 issues rose 5.32 points, or 0.05 percent, at 11,285.36 points in the morning session. The index fell 49.62 points, or 0.44 percent, on Thursday. The dollar was trading at 107.88 yen at 11 a.m. Friday, down 0.40 yen from late Thursday in Tokyo and below the 108.27 yen it bought in New York later that day. Investors picked up technology stocks, including Canon Inc., Advantest Corp. and Kyocera Corp., following gains by the tech-heavy Nasdaq composite index in New York. But buying was cautious as the market awaited the release later Friday of data on U.S. nonfarm payrolls and the May unemployment rate for indications on the health of the American economy. The broader TOPIX, which includes all issues on the Tokyo Stock Exchange's first section, lost 1.22 points, or 0.11 percent, at 1,147.63 points. The TOPIX lost 0.64 points, or 0.06 percent, the day before.
