Until the Democratic Party of Japan (DPJ)'s win in Sunday's election, the Liberal Democratic Party (LDP) had dominated Japanese politics for more than half a century except for short intervals.

The impact on the U.S.-Japan alliance is still not clear. It is hard to divine it from the abstract words of the DPJ's "manifesto" for the election campaign: "In order to build a close and equal U.S.-Japan alliance, Japan will fulfill her responsibilities by sharing them with the United States, based upon an autonomous Japanese diplomatic strategy."

The manifesto contains two concrete proposals: to promote a U.S.-Japan free trade agreement (FTA) and to revise the U.S.-Japan Status of Forces Agreement (SOFA). An FTA would reflect urban, free-trade thinking in contrast to the LDP's policy influenced by its strong constituency in the farming districts. But faced with criticism from farmers, the DPJ toned down its FTA stance during the election campaign.
