Nikkei tracking Wall Street gain

TOKYO (Reuters) - Japan's Nikkei share average jumped 2.8 percent on Wednesday, tracking steep gains on Wall Street after deep interest-rate cut and solid results from two top investment banks soothed investors spooked by Bear Stearns' sudden downfall.

Bank shares such as Mitsubishi UFJ Financial Group (8306.T) were bid up.

At 0005 GMT the benchmark Nikkei .N225 was at 12,296.32 and the broader TOPIX was up 2.6 percent at 1,193.78.
