TOKYO, Nov 4 (Reuters) - The Nikkei average advanced 3.7 percent on Tuesday as exporters gained on a softer yen, while electronics maker Panasonic <6752.T> jumped after sources said it was planning to take over Sanyo Electric <6764.T>.
Japanese markets were closed for a national holiday on Monday, while U.S. stocks ended little changed as investors were unwilling to place big bets before the presidential election. [
]"The Japanese market gained after it was oversold on Friday and after overseas markets were calm during the long weekend," said Masaru Hamasaki, a senior strategist at Toyota Asset Management.
"But after an initial rebound, investors may stay on the sidelines ahead of the U.S. presidential election because the result is also very important to Japan."
Market analysts said they were focused on economic plans that will likely be unveiled by the new U.S. president.
Trends in Tuesday's U.S. presidential election race between Democrat Barack Obama and Republican John McCain could become clear soon after the first polls begin to close at 6 p.m. EST (2300 GMT) in Indiana. [

PANASONIC GAINS, EXPORTERS UP
Shares of Panasonic gained 4.6 percent to 1,582 yen, after rising as much as 9.3 percent at one stage.
Sanyo was untraded due to a glut of buy orders at 195 yen, up 34.5 percent from Friday's close.
Three people familiar with the matter said on Sunday the heads of the two firms have agreed to a deal that would see Panasonic take over Sanyo to create Japan's largest electronics maker. [
]"The reports about Panasonic are also positive for the overall market as they indicate industry realignment could happen across the board and across borders because stocks are so cheap now," said Fumiyuki Nakanishi, manager at SMBC Friend Securities.
The dollar slipped 0.2 percent to 98.97 yen <JPY=> after rising as high as 99.36 yen in early Asian trade on trading platform EBS. Investors welcome a softer yen as it boosts exporters' overseas profits when they are brought back home.
Electronic components maker TDK Corp <6762.T> shot up 8.1 percent to 3,490 yen and Toyota Motor Corp <7203.T> climbed 4.6 percent to 3,900 yen.
Among stocks that fell, Toto Ltd <5332.T> lost 4.5 percent to 642 yen after the toilet and bathroom equipment maker slashed its full-year profit and dividend outlook, hurt by weak housing starts and high raw materials costs.
