House of Representatives (Japan)

House of Representatives (Japan). The House of Representatives is the powerful lower chamber of the National Diet, Japan's bicameral legislature, established under the post-war Constitution of Japan. It holds preeminent authority over legislation, the national budget, and the confirmation of the Prime Minister, and can override decisions by the upper House of Councillors under specific conditions. Members are directly elected through a parallel voting system, and the chamber is dissolved for a general election at least once every four years, though more frequent elections are common.

History

The chamber originated as the elected lower house of the Imperial Diet under the Meiji Constitution, first convening in 1890 after the Meiji Restoration. Its powers were limited, but it became a significant forum for political movements like the Freedom and People's Rights Movement. The modern House was established by the Constitution of Japan, which came into effect in 1947, granting it supreme legislative power. Key historical moments include the political turmoil following the Recruit scandal and the 1993 election which ended the long dominance of the Liberal Democratic Party (LDP). The Koizumi administration and the subsequent Lost Decades saw significant political realignments, including the rise and fall of the Democratic Party of Japan.

Powers and functions

The House of Representatives holds several critical powers that establish its dominance within the National Diet. It has primacy in passing the national budget and ratifying treaties like the Treaty of Mutual Cooperation and Security between the United States and Japan. A vote of no confidence against the Cabinet, passed by the House, forces the cabinet to resign or dissolve the chamber. Most importantly, it can override rejections by the House of Councillors on bills with a two-thirds majority, a power exercised during debates on legislation such as the 2015 security bills. The House also designates the Prime Minister, a decision that takes precedence over the upper house's choice.

Electoral system

Members are elected through a parallel voting system, which combines single-member districts and proportional representation. Voters cast two ballots: one for a candidate in one of 289 first-past-the-post constituencies, and one for a party list in one of 11 proportional representation blocks, which elect 176 members. This system, introduced as part of the 1994 political reforms, replaced the previous multi-member district system and was designed to foster a two-party system. The Ministry of Internal Affairs and Communications administers elections, and the system has been scrutinized for issues like malapportionment and the influence of parties such as Kōmeitō.

Membership and composition

The House is composed of 465 members, known as Diet members. The current composition is dominated by the ruling coalition of the Liberal Democratic Party (LDP) and its partner Kōmeitō. Major opposition parties include the Constitutional Democratic Party of Japan (CDP), Nippon Ishin no Kai, and the Japanese Communist Party. Members must be Japanese citizens aged 18 or over, and the term of office is four years, though it is almost always cut short by a dissolution, as seen in the 2017 and 2021 snap elections. The chamber has seen significant shifts, such as the landslide victory of the Democratic Party of Japan in the 2009 Japanese general election.

Leadership and organization

Presiding officers include the Speaker, elected from among members, who maintains order, and the Vice Speaker. The Speaker, currently Fukushiro Nukaga, is expected to act impartially and traditionally resigns from their party. Day-to-day management is handled by the Secretariat and the Legislative Bureau. Substantive work occurs in standing committees, such as the powerful Committee on Budget and the Committee on Audit. Political negotiation is managed by the Committee on Rules and Administration, and party discipline is enforced by each party's Diet Affairs Committee.

Relationship with the House of Councillors

While the House of Councillors is the upper house, the Constitution grants the House of Representatives superior authority. The lower house's decisions on the Prime Minister, the budget, and treaties prevail in cases of disagreement. For ordinary legislation, the House of Representatives can enact a bill rejected by the House of Councillors by passing it a second time with a two-thirds majority of members present, a mechanism used during the Koizumi administration's postal privatization bills. The requirement for a special session to be convened if the upper house is in recess when the lower house is dissolved ensures continuity. This relationship, often called the "twisted Diet" when different parties control each chamber, was seen during the administration of Naoto Kan following the 2009 Japanese general election.
