Results of the 2003 Japanese general election

This article presents detail of the results in the 2003 Japan general election, breaking down results by block district. The 11 block districts elected 180 members by proportional representation (allocated to party lists in each block by the D'Hondt method), and 300 members were elected from single-member districts distributed among the 47 prefectures.

Five parties qualified to submit lists in each of the block districts. These were New Kōmeitō, the Democratic Party of Japan, the Japan Communist Party, the Liberal Democratic Party, and the Social Democratic Party. In addition, a number of candidates were elected in single-member districts who were independent or belonged to smaller parties. Some of these joined the major parties after the election—notably, the New Conservative Party was subsumed into the LDP.

In each table, the second column shows the number of the seats the party won in a single-member district, the third does that in proportional representation along with the number of votes and the percentage, and the fourth does the total numbers of the seats for the party.

Party names are abbreviated as follows:
 * LDP - Liberal Democratic Party
 * DPJ - Democratic Party of Japan
 * NK - New Kōmeitō
 * JCP - Japan Communist Party
 * SDP - Social Democratic Party
 * Conservative - New Conservative Party
