About this election
Electoral system
Of the 125 seats contested — 124 on the regular three-year cycle plus one by-election seat in Kanagawa to fill a vacancy — 75 were filled in 45 prefectural districts and 50 by nationwide open-list proportional representation. The single-member prefectural districts are decided by first-past-the-post and the multi-member ones by single non-transferable vote. The map shades each prefectural district by its leading party; the merged Tottori–Shimane and Tokushima–Kōchi districts share a colour. The LDP led 42 of the 45 prefectural districts.
