Japanese voters swept the opposition to a historic victory in an election Sunday, ousting the long-ruling conservative party and handing the novice Democrats the job of reviving a struggling economy. The win by the Democratic Party of Japan (DPJ) ends a half-century of almost unbroken rule by the Liberal Democratic Party (LDP) and breaks a deadlock in parliament, ushering in a government that has promised to focus spending on consumers, cut wasteful budget outlays and reduce the power of bureaucrats. But the untested party will have to move quickly to keep support among voters worried about a record jobless rate and a rapidly ageing society that is inflating social security costs. “The people are angry with politics now and the ruling coalition. We felt a great sense of people wanting change for their livelihoods and we fought this election for a change in government,” said Democratic Party leader Yukio Hatoyama. Hatoyama said he wanted to form a coalition with smaller parties whose cooperation is needed in the upper house, but said he wouldn't decide personnel in his new government right away. The Democrats want to forge a diplomatic stance more independent of the United States, raising concerns about possible friction in the alliance. The party has vowed to build better ties with the rest of Asia, often strained by bitter wartime memories. “The LDP is probably going to be missed more in Washington than in Japan,” said Michael Auslin at the American Enterprise Institute in Washington. Media projections showed the Democrats set for a landslide win, possibly taking two-thirds of the seats in parliament's powerful 480-member lower house. That matched earlier forecasts of a drubbing for Prime Minister Taro Aso's LDP. Aso said he took responsibility for the defeat, adding an LDP leadership race to pick a successor should be held soon. The ruling party loss ended a three-way partnership between the LDP, big business and bureaucrats that turned Japan into an economic juggernaut after the country's defeat in World War Two. That strategy foundered when Japan's “bubble” economy burst in the late 1980s and growth has stagnated since. “This is about the end of the post-war political system in Japan,” said Gerry Curtis, a Japanese expert at Columbia University. “It marks the end of one long era, and the beginning of another one about which there is a lot of uncertainty.” Support for the LDP, which swept to a huge election win in 2005 on charismatic leader Junichiro Koizumi's pledges of reform, has crumbled due to scandals, policy flip-flops and a perceived inability to address the problems of a fast-ageing population. But voter backing for the Democrats is less than exuberant. “It's going to be challenging for the DPJ to allocate money properly, but I think we should give them a shot,” said 38-year-old restaurant owner Yasuhiro Kumazawa. “If it doesn't work out, we can re-elect the LDP again in four years.” Hatoyama, 62, the wealthy grandson of a former prime minister, often invoked change during the campaign, a theme that resonated with voters, even if they were unsure his party would pull Japan out of its worst recession in 60 years. The Democrats have pledged to refocus spending on households with child allowances and aid for farmers while taking control of policy from bureaucrats, often blamed for Japan's failure to tackle problems such as a creaking pension system. Analysts worry spending plans by the Democrats, a mix of former LDP members, ex-Socialists and younger conservatives founded in 1998, will inflate Japan's massive public debt and push up government bond yields.
