List of districts of the House of Representatives of Japan

As of 2021^[update],theHouse of Representatives of Japanis elected from a combination of multi-member districts and single-member districts, a method calledParallel voting.Currently, 176 members are elected from 11 multi-member districts (called proportional representation blocks or PR blocks) by a party-list system ofproportional representation(PR), and 289 members are elected from single-member districts, for a total of 465. 233 seats are therefore required for a majority. Each PR block consists of one or moreprefectures,and each prefecture is divided into one or more single-member districts. In general, the block districts correspond loosely to the majorregions of Japan,with some of the larger regions (such asKantō) subdivided.

History

Until the1993 general election,all members of the House of Representatives were elected in multi-member constituencies bysingle non-transferable vote.In 1994, Parliament passed an electoral reform bill that introduced the current system of parallel voting in single-member constituencies and proportional voting blocks.^[1]The original draft bill in 1993 by the anti-LDP coalition of Prime MinisterMorihiro Hosokawaincluded proportional party list voting on a national scale, an equal number of proportional and district seats (250 each) and the possibility of split voting. However, the bill stalled in theHouse of Councillors.^[2]After theLiberal Democratic Party(LDP) had returned to power later that year, it was changed to include proportional voting in regional blocks only, the number of proportional seats was reduced, but the possibility to cast two separate votes was kept in the bill. The electoral reform law was finally passed in 1994. It was first applied in the1996 general election.

Redistricting and reapportionment

Amendments to the electoral law in 2002^[3]and 2013^[4]changed the boundaries of single-member districts and reapportioned seats between prefectures (+5/-5 in 2002; +0/-5 in 2013, resulting in a net change of -5 in district seats in the House of Representatives to 295 and overall seats to 475). The borders of the regional proportional blocks have never changed, but the apportionment of seats to the regional proportional blocks changed in 2000 after the number of proportional seats had been reduced from 200 to 180 (reducing the total number of seats in the lower house from 500 to 480),^[5]and in the 2002 reapportionment.

Another reapportionment was passed by the National Diet in June 2017. In the majoritarian segment, it will change 97 districts in 19 prefectures, six are eliminated without replacement (one each in Aomori, Iwate, Mie, Nara, Kumamoto and Kagoshima). In the proportional segment, four "blocks" lose a seat each (Tōhoku, N. Kantō, Kinki, Kyūshū). Thus, the number of majoritarian seats is reduced to 289, the number of proportional seats to 176, the House of Representatives overall shrinks to 465. The reform takes effect one month after promulgation, i.e. on July 16, 2017.^[6]^[7]
