Exit polls by television broadcasters showed the LDP winning nearly 300 seats in parliament's powerful 480-member lower house, while its ally, the small New Komeito party, looked set to win about 30 seats.
That would give the two parties the two-thirds majority needed to over-rule parliament's upper house, where no party has a majority and which can block bills, which should help to break a deadlock that has plagued the world's third biggest economy since 2007.
An LDP win will usher in a government committed to a tough stance in a territorial row with China, a pro-nuclear energy policy despite last year's Fukushima disaster and a potentially risky prescription for hyper-easy monetary policy and big fiscal spending to beat deflation and tame a strong yen.
Senior executives of the LDP and the New Komeito party met earlier to confirm they would form a coalition if they get a combined majority, Kyodo news agency reported.
"There's no doubt the LDP will team up with the New Komeito in the new government," LDP senior executive Yoshihide Suga told public broadcaster NHK.
Voters had expressed disappointment with Prime Minister Yoshihiko Noda's Democratic Party of Japan (DPJ), which swept to power in 2009 promising to pay more heed to consumers than companies and reduce bureaucrats' control of policymaking
Exit polls showed the DPJ, which was hit by defections ahead of the vote, winning only 65 seats, just over a fifth of their tally in 2009. Party executive Kohei Otsuka told NHK Noda would likely have to quit over the defeat, in which several party heavyweights lost their seats.

Voter distaste for both major parties has spawned a clutch of new parties including the right-leaning Japan Restoration Party founded by popular Osaka Mayor Toru Hashimoto. A dozen parties fielded candidates, confusing many voters.
Exit polls showed Hashimoto's party picking up about 46 seats. That could make it a potential LDP partner if the New Komeito, which is more moderate on security issues than the LDP, decides later to change allies, some analysts said.
LDP leader Abe, 58, who quit as premier in 2007 citing ill health after a troubled year in office, has been talking tough in a row with China over uninhabited isles in the East China Sea, although some experts say he may temper his hard line with pragmatism once in office.
The soft-spoken grandson of a prime minister, who would become Japan's seventh premier in six years, Abe also wants to loosen the limits of a 1947 pacifist constitution on the military, so Japan can play a bigger global security role.
Many economists say that prescription for "Abenomics" could create temporary growth and enable the government to go ahead with a planned initial sales tax rise in 2014 to help curb a public debt now twice the size of gross domestic product.
But it looks unlikely to cure deeper ills or bring sustainable growth, and risks triggering a market backlash if investors decide Japan has lost control of its finances.
Japan's economy has been stuck in the doldrums for decades, its population ageing fast and big corporate brands faltering, making "Japan Inc" a synonym for decline.
Consumer electronics firms such as Sony Corp are struggling with competition from foreign rivals and burdened by a strong yen, which makes their products cost more overseas.

"Japan's conservative Liberal Democratic Party (LDP) "
The conservative LIBERAL party? Is up now down? Is black now white? Where the meanings of thousand year old words changed over night and no one told me? And this...
"An LDP win will usher in a government committed to a tough stance in a territorial row with China, a pro-nuclear energy policy despite last year's Fukushima disaster and a potentially risky prescription for hyper-easy monetary policy and big fiscal spending to beat deflation and tame a strong yen."
So because their conservatives they will beat the war drums louder, favor big energy, print more money and INCREASE govt spending? Obama and his "liberals" has done everyone of these things and then some. And before you say obama doesn't favor big energy just take a look at how BP got off dirt cheap after the oil spill and how they are now immune from individual lawsuits.
