Japanese politics is characterized by a parliamentary system, where the Prime Minister leads the government. The National Diet, Japan's bicameral legislature, consists of the House of Representatives and the House of Councillors. Political parties, such as the Liberal Democratic Party (LDP), play a significant role in shaping policies and governance. Elections in Japan are held regularly, with the Prime Minister typically coming from the majority party in the House of Representatives. The political landscape is influenced by various factors, including public opinion, economic conditions, and international relations, which all contribute to the decision-making process within the government.
