Results

The opposition Democratic Party won a plurality of the popular vote and seats contested in the election, sweeping the liberal urban areas. The ruling Liberal Democratic Party failed to win in its strongholds but once more received most of its support from the agrarian areas. New Komeito did well, reaching its goals, as did the Social Democratic Party. The Japanese Communist Party did not reach its goals, while independents won the rest of the seats. The Liberal League and Midori no kaigi failed to win any seats.

Complete list of prefectural races

Elected candidates in bold

Compiled from JANJAN's "The Senkyo"[1] and MIC official results.[2]

Notes:

  • All incumbents not running for re-election in their prefectural electoral district are counted as retirements even if they ran in the nationwide proportional representation.
  • In a multi-member district, there is no difference between Councillors elected with the highest and lower vote shares. Yet, "top tōsen", i.e. being elected with the highest vote, is considered a special achievement and thus noted where changed from the previous election for the same class of Councillors (1998).
  • Niigata is counted as an SDP hold because the elected Councillor joined the SDP parliamentary group.
