About this election
Electoral system
Of the 125 seats contested, 75 were elected in the 45 prefectural districts and 50 by nationwide open-list proportional representation. The single-member districts use first-past-the-post and the multi-member districts single non-transferable vote, while voters cast a separate party or candidate vote for the national proportional tier. The map shades each prefectural district by its leading party. The LDP led 26 districts — far fewer than in previous cycles — as the Constitutional Democrats, the Democratic Party for the People and independents carried many of the rest; the merged Tottori–Shimane and Tokushima–Kōchi districts are shown identically in both prefectures.
