The politics of Japan are conducted in a framework of a dominant-party bicameral parliamentary representative democratic constitutional monarchy. A hereditary monarch, currently Emperor Naruhito, serves as head of state while the Prime Minister of Japan, currently Shigeru Ishiba since 2024, serves as the elected head of government.
The National Diet is the national legislature of Japan. It is composed of a lower house, called the House of Representatives, and an upper house, the House of Councillors. Both houses are directly elected under a parallel voting system. In addition to passing laws, the Diet is formally responsible for nominating the prime minister. The Diet was first established 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 in Nagatachō, Chiyoda, Tokyo.
The House of Representatives is the lower house of the National Diet of Japan. The House of Councillors is the upper house. The composition of the House is established by Article 41 and Article 42 of the Constitution of Japan. The House of Representatives has 465 members, elected for a four-year term. Of these, 176 members are elected from 11 multi-member constituencies by a party-list system of proportional representation, and 289 are elected from single-member constituencies.
The House of Councillors 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 the nomination 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 Social Democratic Party is a political party in Japan that was established in 1996. Since its reformation and name change in 1996, it has advocated pacifism and defined itself as a social-democratic party. It was previously known as the Japan Socialist Party.
