TOKYO, Jan 19 (Reuters) - Japanese shares fell on Wednesday, dragged down by Sony Group, Toyota Motor and other market heavyweights, tracking Wall Street"s weak finish overnight. The Nikkei share average (.N225) fell 1.5% to 27,828.60 by 0135 GMT, after losing as much as 2% earlier, while the broader Topix (.TOPX) lost 1.54% to 1,947.94. Wall Street"s main indexes fell sharply overnight, as weak results from Goldman Sachs weighed on financial stocks and tech shares continued their sell-off as U.S. Treasury yields rose to milestones. "Japanese shares fell across the board today because of the declines on Wall Street. Among several reasons that weighed on the U.S. stocks, oil price hike is the most critical to Japan because it would raise costs for Japanese companies," said Takatoshi Itoshima, strategist at Pictet Asset Management. "Investors will remain cautious about rising U.S. interest rates. For that reason, the market could remain tepid until the FOMC (U.S. Federal Open Market Committee) next week."
