This paper attempts to clarify and analyze the major factors behind the ruling Liberal Democratic Party's (LDP) huge loss and the Democratic Party of Japan's (DPJ) overwhelming win in the single-seat constituencies (there are a total of 29 throughout the country), the results that decided the final outcome of the 21st House of Councilors Election held on 29 July 2007. Analysis of the election results reveals that, first, there was a shift in support from the LDP to the DPJ among primary-industry and construction workers, who were hard hit by the structural reform drive under the Koizumi and Abe administrations, and second, that since unified local elections had taken place a few months earlier, many LDP supporters, tired out by their efforts in local-level elections, lost interest in the Upper House election and did not go to the polls (a situation known as the Year of the Boar phenomenon).
