The Japanese political landscape is characterized by a parliamentary system, where the Prime Minister serves as the head of government. The National Diet is Japan's bicameral legislature, consisting of the House of Representatives and the House of Councillors. The ruling party, typically the Liberal Democratic Party (LDP), has dominated politics for decades, influencing policy and governance. Political parties in Japan range from conservative to progressive, with the LDP being the most prominent. Other parties, such as the Constitutional Democratic Party and the Japanese Communist Party, also play significant roles. Voter participation and public opinion can impact elections, shaping the future of Japan's governance.
