The Tōkyō proportional representation block (Hirei [daihyō] Tōkyō burokku (比例[代表]東京ブロック)), or more formally the proportional representation tier "Tokyo Metropolis electoral district" (東京都選挙区, Tōkyō-to senkyo-ku), is one of eleven proportional representation (PR) "blocks", multi-member constituencies for the House of Representatives in the Diet of Japan. It consists solely of the prefecture of Tokyo making it one of two blocks covering only one prefecture, the other being Hokkaido. Following the introduction of proportional voting Tokyo elected 19 representatives by PR in the 1996 general election, and 17 since the election of 2000 when the total number of PR seats was reduced from 200 to 180.

## Summary of results

[edit]

Beyond remote parts of Western Tokyo on the mainland and the Izu and Ogasawara islands, Tokyo's population is concentrated in urban and suburban areas. Reformist and left-of-center parties have usually won a majority of votes and seats. In the landslide "postal privatization" election of 2005 though, the LDP won a record 2.6 million votes in Tokyo; it would have received eight seats but hadn't nominated enough candidates: Of its 30 PR list candidates, 24 concurrently ran in single-member districts as dual candidates; 23 won their district races, leaving only a total of seven list candidates to be elected by PR. One seat went to the SDP as it would have been assigned a hypothetical, 18th seat under the d'Hondt method.
