This article presents detailed results of the 2017 Japanese general election. The results are separated into each of the eleven proportional representation blocks and their corresponding prefectures. In the following tables, candidates elected via single-member district are highlighted in green, while candidates elected via proportional representation are highlighted in red.

Electoral system

The House of Representatives is elected via parallel voting. In the 2017 election, 289 members were elected in single-member districts and 176 via party-list proportional representation in eleven multi-member constituencies, referred to as "PR blocks". Single-member districts are apportioned between prefectures and numbered (1st, 2nd, etc). Candidates may run solely in a single-member district, solely in PR, or both (dual listing). Dual listed candidates must win at least 10% of the vote in their single-member district in order to be eligible for election via PR. Dual listed candidates who win their single-member district race are not eligible for election via PR.

Candidates on PR lists may be ranked sequentially or, if they are dual listed, ranked equally with one another. If ranked equally, the best-loser ratio (sekihairitsu) of each candidate determines the order of election. This number is determined by dividing their single-member district votes by those of the winning candidate in that district. In this way, the losing candidates who performed best will be elected first.

If a party wins more seats than they have eligible candidates in a PR block, their seats will be distributed to other parties in accordance with the PR formula.
