About this election
Electoral system
Of the 124 seats contested in 2019, 74 were elected in 45 prefectural districts (by first-past-the-post or single non-transferable vote) and 50 by open-list proportional representation nationwide. The 2018 reform also introduced a partly closed element to the proportional lists, letting parties designate certain candidates for priority election ahead of the open-list ranking — a device used in part to find seats for representatives of the merged Tottori–Shimane and Tokushima–Kōchi districts. The map colours each prefectural district by its leading party; the two merged districts are shown identically.
