The LDP under Ryūtarō Hashimoto had restored single-party government in 1996 and was now aiming to also regain clear control of the House of Councillors where it was several seats short of a majority. Instead, it lost 13 seats in the election giving the opposition clear control. Prime minister Hashimoto resigned. Keizō Obuchi was elected LDP president on July 24, defeating Seiroku Kajiyama and Junichirō Koizumi.

On July 30, 1998, Obuchi was designated as prime minister by the Diet against the vote of the House of Councillors where DPJ president Naoto Kan beat Obuchi by 142 to 103 votes. Obuchi entered coalition negotiations in late 1998. In January 1999, the LDP entered a ruling coalition with Ichirō Ozawa's Liberal Party, bringing the government within few seats of a majority; in October 1999, New Komeito also entered the coalition, ending the divided Diet.

Results

Note that because of the dissolution of the Socialist Party in 1996 (→Social Democratic Party, New Socialist Party, Democratic Party), the Democratic Socialist Party and the Kōmeitō in 1994, the creation and subsequent dissolution of the New Frontier Party, the (re-)establishment of the two "New" Kōmeitō predecessors and several other party mergers, creations and dissolutions in the 1990s, many of the incumbent Councilors in 1998 belonged to a different party than the ones they were elected for in 1992.

Elected candidates in bold

Compiled from JANJAN's "The Senkyo"[1] and Ministry of Internal Affairs and Communications 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 (1992). (due to the many party realignments in the 1990s only where changed from LDP to opposition or vice versa)
• In the results column, independents are counted towards the party they joined in the first Diet sessions after the election.
