TOKYO (Reuters) - Japan Prime Minister Shinzo Abe dissolved Parliament's Lower House for an election on Friday, seeking a fresh mandate for his struggling Abenomics revival strategy just two years after he returned to power promising that "Japan is Back".
The Speaker of the Lower House read the dissolution proclamation to a plenary session of the chamber.
No election for Parliament's Lower House needed to be held until late 2016. But Mr Abe is hoping to cement his grip on power before his support ratings, now below 40 per cent in some surveys but still sturdy by Japanese standards, slip further.
The date of the election, expected to be on Dec 14, will officially be set at a Cabinet meeting in the afternoon.
Mr Abe had vowed to revive the economy with a mix of hyper-easy monetary policy, government spending and reforms, while moving ahead with plans to rein in Japan's massive public debt.
But doubts have grown about his strategy, especially after data showed this week that the economy had surprisingly slipped into recession in the third quarter after an initial rise in the sales tax to 8 per cent from April.
Mr Abe has said he would delay for 18 months a second tax hike to 10 per cent that had been slated for October 2015. He pledged that the second increase, which advocates say is needed to fund the bulging social security costs of a fast-ageing population, would go ahead in April 2017.
No general election needed to be held until late 2016.
But Mr Abe hopes to cement his grip on power before his support ratings slip too far. Next year, he plans to tackle unpopular policies such as restarting reactors that went off-line after the 2011 Fukushima nuclear crisis.
An Asahi newspaper poll published on Friday showed Mr Abe's support fell to 39 per cent - the lowest since he took office in December 2012 - and just a bit more than the 40 per cent who do not back him.
Still, 37 per cent said they would vote for Abe's Liberal Democratic Party (LDP) in proportional representation districts, compared to 13 per cent who planned to vote for the main opposition Democratic Party of Japan (DPJ).
Thirty per cent were undecided. "Unfortunately, the DPJ has not recovered to a point where we can say to voters, 'Entrust the government to us'," DPJ Secretary General Yukio Edano told a news conference. The Democrats were trounced in 2012 after three years in power.
Mr Edano said the DPJ wanted to give voters a choice between Mr Abe's "trickle down" policies that critics say favour the rich and big firms, and the Democrats' "bottom up" strategy that focuses on the middle class.
Faced with a weak and divided opposition, the LDP and its junior partner, the Komeito party, are not expected to lose their majority in the lower house, where they held two-thirds of the 480 seats. There will be 475 seats up for grabs this time after reforms to rebalance between sparsely populated rural districts and dense urban areas.
Mr Abe said he would resign if his coalition failed to win a majority, an outcome experts dismissed as almost impossible, though he could end up weakened if the LDP loses too many seats.
