wikipedia article:

Japan is a constitutional monarchy, although the powers the Emperor (天皇 tennō, literally "heavenly sovereign") wields is severely curtailed. He is defined by the Constitution of Japan as "the symbol of the state and of the unity of the people". As a ceremonial figurehead he does not wield even emergency reserve powers. Power is held chiefly by the Prime Minister, and other elected members of the Diet. Sovereignty is vested in the Japanese people by the constitution. Although not stated so, the emperor effectively acts as the head of state on diplomatic occasions. Akihito is the current emperor and the only reigning emperor in the world.

Japan's legislative organ is its bicameral parliament, the National Diet (Kokkai). The Diet consists of a House of Representatives (Lower House or Shūgi-in) containing 480 seats, elected by popular vote every 4 years or when dissolved, and a House of Councillors (Upper House or Sangi'in) of 242 seats, whose popularly-elected members serve six-year terms. There is universal adult (over 20 years old) suffrage, with a secret ballot for all elective offices. The liberal conservative Liberal Democratic Party (LDP) has been in power since 1955, except for a short-lived coalition government formed from its opposition parties in 1993; the largest opposition party is the liberal-socialist Democratic Party of Japan.

The Prime Minister of Japan is the head of government of Japan, although the literal translation of the title is "Prime Minister of the Cabinet". The Prime Minister is appointed by the Emperor of Japan after being designated by the Diet from among its members, and must enjoy the confidence of the House of Representatives to remain in office. The Prime Minister is the head of the Cabinet of Japan and appoints and dismisses the Ministers of State, a majority of whom must be Diet members. The current Prime Minister of Japan, since September 2006, is Shinzo Abe. Although the Prime Minister of Japan is theoretically very powerful, his position is attenuated by the factional nature of Japanese politics and the tendency towards coalition government.
