Dates of elections / renewal (from/to):

  18 February 1990

Purpose of elections:

  Elections were held for all the seats in the House of Representatives following premature dissolution of this body on 24 January 1990. General Representatives elections had previously taken place in July 1986.

Background and outcome of elections:

  Subsequent to the previous (July 1986) general Representatives elections, and especially since mid-1988, the ruling Liberal-Democratic Party (LDP) had suffered a loss of prestige as the result of internal turmoil, various scandals involving top party officials and the imposition of a highly unpopular national sales tax. Public opinion polls published in January 1990 gave the Government of Prime Minister Toshiki Kaifu an approval rating under 40%. The premature 1990 election was thus widely expected to be a showdown between the LDP and the Japan Socialist Party (JSP), which had scored big gains in polling for the Diet’s Upper House (Councillors) in July 1989, thereby winning control for the opposition there.

Altogether 953 candidates contested 512 Representatives’ seats. The 15-day campaign commenced with a televised debate among the main party leaders. Debate focused on economic issues – especially the consumption tax, external trade and protection for farmers – and the worth of socialism or communism in the contemporary world, but also to a significant degree on local questions. The opposition parties were hurt by a lack of cohesion and a common platform.

On polling day, LDP made a surprisingly strong showing, retaining a comfortable House majority, especially with allied right-wing independents. JSP, led by Mrs. Takako Doi, recorded major gains to arrive at 136 seats, but a number of its triumphs came at the expense of other, smaller opposition parties rather than the LDP. Observers attributed this outcome to the electorate’s overriding wish for continued political stability. On the basis of the voting results, a new 21-member Cabinet headed by Prime Minister Kaifu was sworn in on 28 February 1990. The LDP has been in power since 1955.
