(Adds details, trade volume)

TOKYO, May 2 (Reuters) - Japan's Nikkei stock average rose more than 2 percent on Friday to its highest close in nearly four months, buoyed by exporters such as Advantest Corp (6857.T: Quote, Profile, Research, Stock Buzz) on a softer yen and a rally on Wall Street amid growing optimism about the U.S. economy.

The benchmark Nikkei has now gained 20 percent since hitting a low for the year on March 17, handily outperforming a roughly 12 percent rise in the U.S. Standard & Poor's 500 Index .SPX and the pan-European FTSEEurofirst 300 index during the same period.

Property firm Sumitomo Realty & Development Co (8830.T: Quote, Profile, Research, Stock Buzz) shot up more than 7 percent after a newspaper reported its profits were likely to beat forecasts. Other real estate stocks also rose on the back of strong earnings, helped by demand for office space in Tokyo.

Bank shares tracked gains in their U.S. peers due to improved investor confidence a day after the Federal Reserve trimmed rates again and hinted at a pause in its recent campaign to lower borrowing costs.

On the negative side, Japan Tobacco Inc (2914.T: Quote, Profile, Research, Stock Buzz) slid 4.1 percent to 490,000 yen after the world's third-largest cigarette maker forecast a 28 percent fall in profit this year due to an accounting change, its first drop in eight years. This prompted Goldman Sachs to remove the stock from its "conviction buy list" and lowered the target price. [ID:nT2944]

"Today's market is buoyed by a rally in the United States and a softer yen. But investors seem to have become too optimistic about the U.S. economy recently as jobs data later today is still expected to be poor," said Soichiro Monji, a chief strategist of the equity management department at Daiwa SB Investments.

"The Nikkei's 14,000 looks to be the ceiling for now. If it goes above that level, stocks are overbought under the current conditions."
