General elections were held in Japan on 7 October 1979 to elect the 511 members of the House of Representatives. Prime Minister Ōhira Masayoshi's announcement that a consumption (sales) tax would be imposed was a hot-button issue in the run-up to the election. Facing widespread public disapproval, the prime minister abandoned the tax proposal. The prime minister's party, the Liberal Democratic Party (LDP), ended up losing one seat, while the Japan Communist Party experienced a surge in voter support and its best ever electoral result, which mostly came at the expense of the Japan Socialist Party and the LDP-breakaway New Liberal Club.
House of Councillors elections were held in Japan on 22 June 1980. On 16 May the Japan Socialist Party (JSP) brought no-confidence motion before the Diet relating to corruption issues, proposing more defense spending and rises in public utility charges as reasons for the House of Representatives to withdraw its backing from the government. Unexpectedly, 69 Liberal Democratic Party (LDP) members of the Diet from the Fukuda Takeo, Miki Takeo and Hidenao Nakagawa factions abstained from voting on the motion. The government was defeated by 56 votes in total of 243 and resigned. For the first time elections for both the House of Councillors and the House of Representatives were elected at the same time. In the elections of both the houses the LDP gained a majority.
A leadership election was held in the Liberal Democratic Party of Japan on 23 September 2007 after the incumbent party leader and Prime Minister of Japan Shinzō Abe announced that he would resign on 12 September 2007. Abe had only been elected to the post slightly less than a year earlier; his resignation came only three days after a new parliamentary session had begun. Abe said his unpopularity was hindering the passage of an anti-terrorism law, involving among other things Japan's continued military presence in Afghanistan. Party officials also said the embattled Prime Minister was suffering from poor health.
Factions are an accepted part of the Liberal Democratic Party (LDP), the ruling party of Japan, which began with eight formal factions when it was first formed by merger in 1955. A political faction may be defined as a sub-group within a larger organization. While factions characterize other political parties in Pacific Asia, Japanese factionalism is distinguished by its stability and institutionalization. Although factions reconstitute themselves from time to time, the habatsu active today can be traced back to their 1955 roots, a testament to the stability and institutionalized nature of Liberal Democratic Party factions.
