Japan's legislative organ is the National Diet, a bicameral parliament. It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper House of Councillors with 245 seats, whose popularly-elected members serve six-year terms. There is universal suffrage for adults over 18 years of age, with a secret ballot for all elected offices. The prime minister as the head of government has the power to appoint and dismiss Ministers of State, and is appointed by the emperor after being designated from among the members of the Diet. Fumio Kishida is Japan's prime minister; he took office after winning the 2021 Liberal Democratic Party leadership election. The right-wing big tent Liberal Democratic Party has been the dominant party in the country since the 1950s, often called the 1955 System.
