Politics in Japan

The politics of Japan is conducted in a framework of a multi-party bicameral parliamentary representative democratic constitutional monarchy whereby the Emperor acts as the ceremonial head of state, and the Prime Minister is the head of government and the head of the Cabinet, which directs the executive branch.

Legislative power is vested in the National Diet, which consists of the House of Representatives and the House of Councillors. Judicial power is vested in the Supreme Court and lower courts, and sovereignty is vested in the Japanese people by the Constitution. Japan is considered a constitutional monarchy with a system of civil law.

The Constitution of Japan defines the Emperor to be "the symbol of the State and of the unity of the people". He performs ceremonial duties and holds no real power. Political power is held mainly by the Prime Minister and other elected members of the Diet. The Imperial Throne is succeeded by a member of the Imperial House as designated by the Imperial Household Law.
