Parliamentary Cabinet System
The Prime Minister is designated from among the Members of the Diet by a resolution of the Diet. The Cabinet is collectively responsible to the Diet in the exercise of executive power. If the House of Representatives passes a non-confidence resolution, either the House of Representatives must be dissolved or the Cabinet must resign en masse. Such a system where the Cabinet, or executive branch of government, is dependent on the support of the Diet, or legislative branch, to exist is called a parliamentary cabinet system.
