The People's New Party was a Japanese political party formed on August 17, 2005, in the aftermath of the defeat of Prime Minister Junichiro Koizumi's Japan Post privatisation bills which led to a snap election.

Prefectural elections for the Tokyo Metropolitan Assembly were held on 12 July 2009. In the runup to the Japanese general election due by October they were seen as an important test for Taro Aso's ruling coalition of the Liberal Democratic Party (LDP) and the New Komeito. New Komeito considers Tokyo as an important stronghold and had repeatedly asked Prime Minister Aso to avoid holding the two elections within a month of each other.
The Shikoku proportional representation block is one of eleven proportional representation (PR) "blocks", multi-member constituencies for the House of Representatives in the Diet of Japan. It consists of Shikoku region covering Tokushima, Kagawa, Ehime and Kōchi Prefectures. Following the introduction of proportional voting it elected seven representatives in the 1996 general election. When the total number of PR seats was reduced from 200 to 180, the Shikoku PR block shrank to six seats.

It is located in Western Yamaguchi and consists of the cities of Shimonoseki and Nagato. The seat was held by former Prime Minister of Japan Shinzo Abe until his assassination in July 2022. As of September 2011, 266,456 voters were registered in the district, giving its voters well above average vote weight. Unlike many prefectures where the capital is also the most populous city, Yamaguchi's major city is Shimonoseki, located at the western tip of Honshū and adjacent to Kyushu island's Fukuoka-Kitakyūshū metropolitan area which lies just south across the Kanmon Straits.
General elections were held in Japan on 14 December 2014. Voting took place in all Representatives constituencies of Japan including proportional blocks to elect the members of the House of Representatives, the lower house of the National Diet of Japan. As the cabinet resigns in the first post-election Diet session after a general House of Representatives election, the lower house election also led to a new election of the prime minister in the Diet, won by incumbent Shinzō Abe, and the appointment of a new cabinet. The voter turnout in this election remains the lowest in Japanese history.
The 2014 Tokyo gubernatorial election took place on February 9, 2014 to replace outgoing Governor Naoki Inose, who resigned effective December 24, 2013.

His final tally was 2,112,979 votes (42.86%), with his two closest competitors Morihiro Hosokawa and Kenji Utsunomiya failing to break the 20% mark.

Voting took place in all Representatives constituencies of Japan – 289 single-member districts and eleven proportional blocks – in order to appoint all 465 members of the House of Representatives, the lower house of the then 707-member bicameral National Diet of Japan. Incumbent Prime Minister Shinzō Abe's governing coalition of the Liberal Democratic Party (LDP) and the Komeito party retained their seats in signs of what was perceived as weak opposition. The PM won his fourth term in office and held on to the two-thirds supermajority in order to implement policies on revising the war-renouncing Article 9 of the Japanese Constitution.
The Second Koizumi Cabinet was the cabinet of Japanese Prime Minister Junichiro Koizumi during his second term from November 2003 to September 2005. The cabinet was formed after the coalition of the Liberal Democratic Party and the Komeito was re-elected with a slightly reduced majority at the November 2003 general elections. The LDP lost 10 of its pre-election seats to become a minority in the National Diet, but immediately regained a majority by absorbing its coalition partner, the New Conservative Party. Koizumi had reshuffled the cabinet less than two months before the election, and so made no changes when he was re-elected by the Diet on November 19.
