保守新党
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.
