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: Quote, Profile, Research, Stock Buzz) 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.
