House of Representatives (Japan)

The National Diet Building (国会議事堂, Kokkai-gijidō) is the building where both houses of the National Diet of Japan meet. It is located at Nagatachō 1-chome 7–1, Chiyoda, Tokyo. Sessions of the House of Representatives take place in the left wing and sessions of the House of Councillors in the right wing. The Diet Building was completed in 1936 and is constructed out of purely Japanese materials, with the exception of the stained glass, door locks, and pneumatic tube system.

The National Diet (Japanese: 国会, Hepburn: Kokkai) is Japan's bicameral legislature. It is composed of a lower house, called the House of Representatives (衆議院, Shūgiin), and an upper house, the House of Councillors (参議院, Sangiin). Both houses are directly elected under a parallel voting system. In addition to passing laws, the Diet is formally responsible for selecting the Prime Minister. The Diet was first convened as the Imperial Diet in 1890 under the Meiji Constitution, and took its current form in 1947 upon the adoption of the post-war constitution. Both houses meet in the National Diet Building (国会議事堂, Kokkai-gijidō) in Nagatachō, Chiyoda, Tokyo.

Kokkai-gijidomae Station (国会議事堂前駅, Kokkai-gijidō-mae-eki) is a subway station in Chiyoda, Tokyo, Japan, operated by the Tokyo subway operator Tokyo Metro. It is located adjacent to the National Diet Building. The station name literally means "in front of the National Diet Building".

The House of Councillors (参議院, Sangiin) is the upper house of the National Diet of Japan. The House of Representatives is the lower house. The House of Councillors is the successor to the pre-war House of Peers. If the two houses disagree on matters of the budget, treaties, or designation of the prime minister, the House of Representatives can insist on its decision. In other decisions, the House of Representatives can override a vote of the House of Councillors only by a two-thirds majority of members present. The House of Councillors has 245 members who each serve six-year terms, two years longer than those of the House of Representatives. Councillors must be at least 30 years old, compared with 25 years old in the House of Representatives. The House of Councillors cannot be dissolved, and terms are staggered so that only half of its membership is up for election every three years. Of the 121 members subject to election each time, 73 are elected from 45 districts by single non-transferable vote (SNTV) and 48 are elected from a nationwide list by proportional representation (PR) with open lists.
