The National Diet is the legislative body of Japan, consisting of two houses: the House of Representatives and the House of Councillors. It is responsible for making laws, approving the budget, and overseeing the government. Members of the National Diet are elected by the public, and the Diet meets in the National Diet Building located in Tokyo. The House of Representatives has more power than the House of Councillors, including the ability to select the Prime Minister. The National Diet plays a crucial role in Japan's democratic system, ensuring that the government is accountable to the people and that their voices are heard in the legislative process.
