How are leaders selected in Japan?

Answer 1

Japan is Constitutional monarchy (Emperor Akihito), but the real power rests with the Prime Minister (Shinzo Abe), who is elected with other members to the Diet.

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, 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 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.
