The Hokkaidō proportional representation block (比例[代表]北海道ブロック, Hirei [daihyō] Hokkaidō burokku) or in official usage the "Hokkaidō electoral district" (北海道選挙区, Hokkaidō senkyo-ku) is one of eleven proportional representation (PR) blocks for the House of Representatives in the Diet of Japan. It consists of Hokkaidō and is one of two PR blocks that covers only one prefecture, the other being Tokyo. Following the introduction of proportional voting, it elected nine representatives in the election of 1996. Since 2000, the Hokkaidō PR block has been represented by eight representatives.

Summary of results

With eight seats, Hokkaidō is the second-smallest PR block ( Shikoku has only six seats), and the vote share needed to gain a seat is usually above ten percent. In 2000, when the combined vote of the two major parties reached a low of 56.8%, the Social Democratic Party managed to obtain a seat with only 8.9% of the vote (for a detailed explanation, see D'Hondt method).

In addition to the five national parties that emerged from the party realignments of the 1990s, the regionalist one-man party New Party Daichi has become a contender for PR seats in Hokkaidō. In the first three elections in which it fielded candidates, it managed to obtain the third-largest vote share and one seat. In 2012, the Liberal Democratic Party became first party in the Hokkaidō proportional election for the first time, and has narrowly held onto that position in 2014 and 2017.

"narrow defeat ratio"), the ratio of margin of defeat. It determines the ranking of candidates who are put on the same list rank by their party.
  • (in parentheses): Double candidates who are not eligible for election in the proportional block either because they won their district races or were disqualified for having received less than 10% of the vote in the district race (the same threshold as for losing the deposit in the single-member district election)
