In March 1994, a new electoral system was introduced for the House of Representatives following the passage of the long-debated political reform laws in the Diet. It consists of a combination of single-seat constituencies and proportional representation and was intended to rectify problems arising under the old system of multi-seat constituencies.
Under the new system, the number of seats in the lower house was reduced from 511 to 500. It also introduced both single-seat constituencies and proportional representation constituencies for the lower house elections (300 seats from single-seat constituencies, 200 seats from proportional representation constituencies). After that, the number of seats in the lower house was reduced again to 480, with 300 seats allotted to the single-seat constituencies and 180 to the proportional representation constituencies, which are demarcated by dividing the country into 11 blocs. In single-seat constituencies, voters select the individual candidate, while in the proportional representation blocs they vote for a party.
In the single-seat districts, the candidate with the largest number of votes wins. Winners of the proportional representation contest are selected from ranked lists of candidates for each bloc that are submitted ahead of time by each party; votes are tallied by bloc, and winners are apportioned among the parties on the basis of the percentage of the vote each party has obtained.
Following revision of the law in October 2000, the number of upper house seats was reduced from 252 to 242. (Since regular upper house elections take place for half of the seats every three years, the number of seats contested in the July 2001 election was reduced by 5—that is, half of the total decrease. Therefore, the upper house has 247 seats for the three years until the next election in 2004.) Of the total number of seats, 96 are allotted to a single nationwide proportional representation constituency, in which voters can vote for either a party or an individual candidate, and 146 allotted to electoral districts, in which voters opt for specific candidates.
Citizens over 25 years of age are eligible for election to the House of Representatives, and those 30 and over may be elected to the House of Councillors. Japan has universal adult suffrage, with all men and women of 20 years and over being eligible to vote in all elections. Universal male suffrage was achieved in 1925. Women were first granted the right to vote in late 1945 after World War II.
