TOKYO: It took 54 years for Japan’s politics to produce a viable opposition party, and 39 months for it to self-destruct after winning power, splintering prospects for an enduring policy-driven two-party system.

The Democratic Party of Japan lost three-fourths of its seats in parliament’s lower house three years after sweeping the Liberal Democratic Party from a half-century of almost unbroken rule. An LDP-led coalition won a two-thirds majority in the 480-seat chamber, according to public broadcaster NHK.

While the DPJ’s leaders came under fire for the response to the March 2011 earthquake and nuclear disaster, the biggest collapse in public support preceded the crisis. Undermined by a faction boss who later split and took about 50 seats with him, the DPJ flubbed its historic chance at the beginning by pledging to move a US military base off Okinawa, then reneging on it.

“It was a missed opportunity for now to build a true two-party system," said Ellis Krauss, a professor of Japanese politics at the University of California, San Diego. “Japan's major challenges, including an aging society and a huge debt problem, would be manageable if only the political system weren’t so dysfunctional. I’m fairly pessimistic the political leadership will confront the problems any time soon.”

The DPJ lost more than 173 of its 230 seats in the lower house, NHK’s vote count showed, the worst showing of any governing party since the end of World War II. The Japan Restoration Party, led by ex-Tokyo Governor Shintaro Ishihara and Osaka Mayor Toru Hashimoto, won almost as many seats as the DPJ, making it the third-largest group.

“They talked big but they couldn’t deliver," said Masatsugu Kitano, a 77-year-old company executive in Tokyo, speaking days before Sunday’s election, referring to the DPJ. “My trust in political parties is basically zero.”

Prime Minister Yoshihiko Noda, the DPJ's third premier in as many years, said he would quit as party leader. LDP leader Shinzo Abe, in line to reclaim the office he left in 2007, said voters “will be looking carefully at the LDP to see if we fulfil their expectations”.

After governing for all but 10 months since 1955, the LDP was ousted in 2009 by the DPJ, which vowed to curb bureaucrats’ power, cut public works spending and boost child support. Instead, the child payments were cut back and Noda this year pushed through a bill doubling the sales tax to cope with record debt, fulfilling a decade-long push by the ministry of finance.

Yukio Hatoyama, the DPJ's initial premier, entered office pressing a pledge to relocate the Marine Corps Air Station Futenma. Designed to reduce the burden of American military operations on the people of Okinawa, the move backfired when it soured relations with Japan's top ally, stirring concern among the nation's business community.

Hatoyama later reversed course, inciting criticism from Okinawans who had anticipated the government following through on its commitments. His approval rating sank below 20 per cent, from 75 per cent, and he stepped down after eight months in office. Naoto Kan, who Sunday fought to hold off an LDP challenge for his own seat in the Diet, took over.

“The biggest reason for the DPJ’s downfall was it went into the election with a manifesto, and said it would carry out those promises,’’ said Kazuhisa Kawakami, a professor of political science at Meiji Gakuin University in Tokyo. “Then of course there was the problem of the Okinawa base, which did in Hatoyama.”

The LDP, the product of a merger of parties in the postwar re-establishment of democracy in Japan, governed for decades with little more than a Socialist opponent that failed to gain traction with the centrist voters.

With Japan’s rapid development through the 1960s and 1970s, and the success of its powerhouse automakers, steel producers, shipyards and electronics companies, the party found its dominance unchallenged. Support for public works and the construction industry helped seal its hold on power.

A burst property and stock-market bubble undermined the model in the early 1990s. Ichiro Ozawa, an LDP lawmaker who was an acolyte of 1970s Prime Minister and power broker Kakuei Tanaka, helped overthrow the party in 1993. Even so, the coalition government that resulted proved unstable and lasted only 10 months.

With Japan’s economy contracting and social welfare costs rising in the world's most-rapidly aging society, Abe will be under pressure to deliver the kind of results he couldn't last time. The DPJ remains the biggest party in the upper house of parliament, and could still rebound in elections for the chamber in July should the LDP prove a disappointment again.

Stocks climbed in the weeks leading up to the election as investors bet that Abe will follow through on speeches calling for the central bank to step up monetary stimulus.

The Nikkei 225 Stock Average advanced 12 per cent in the past month.

Yet Abe will inherit a recessionary economy, with electronics champions from Sharp Corp. to Sony Corp. struggling to cope with the yen’s climb in the past half decade and intensified Korean competition. Public debt has grown by about a fifth since his last term in office, cut short by intestinal illness.

Steven Reed, a political scientist at Chuo University, points out that the Democrats’ 2009 landslide followed a decisive defeat four years before. ‘‘People said in 2005 that the Democrats would never recover and after 2009 that the LDP could never recover,’’ Reed said. ‘‘I think quite the reverse.’’
