About this election

Electoral system

Members are elected through parallel voting: 289 by first-past-the-post in single-member districts and 176 by proportional representation in 11 regional blocs, with separate constituency and party-list ballots. Because the tiers are not linked, a strong, geographically even showing in the urban PR blocs can offset constituency weakness — exactly what Ishin achieved, winning many list seats nationwide on top of its Osaka district sweep. Each prefecture on the map is shaded by the party winning the most of its single-member districts.
