the Cabinet
内閣
The body that holds executive power: the Prime Minister and the other Ministers of State (Articles 65 and 66). It administers the law, conducts foreign affairs, prepares the budget and issues Cabinet Orders (政令); Article 73 is the list. It answers to the Diet as a body (Article 66, paragraph (3)), and must resign if the House of Representatives passes a vote of no confidence and is not dissolved within ten days (Article 69).

the Diet
国会
Japan's parliament, and under Article 41 the only body that can make an Act (法律). It has two chambers, the House of Representatives and the House of Councillors, both made up of elected members (Articles 42 and 43). It designates the Prime Minister, approves the budget and treaties, and can start the process of amending the Constitution. A Cabinet Order (政令) or Ministerial Order (省令) may impose a duty or a penalty only where an Act the Diet passed says it may.

Emperor
天皇
The symbol of the State and of the unity of the people, holding that position by the will of the people (Article 1). The Emperor performs only the acts in matters of state the Constitution lists — appointing the Prime Minister the Diet has designated, promulgating laws, convoking the Diet — and has no powers related to government at all (Article 4, paragraph (1), and Articles 6 and 7). Every one of those acts needs the Cabinet's advice and approval, and the Cabinet, not the Emperor, answers for it (Article 3).

Prime Minister
内閣総理大臣
The head of the Cabinet. Designated by the Diet from among its own members, and appointed by the Emperor on that designation (Articles 67 and 6). The Prime Minister appoints and may dismiss the other Ministers of State at will, and a majority of them must be members of the Diet (Article 68). No Minister of State can be subjected to legal action while in office without the Prime Minister's consent (Article 75).

Supreme Court
最高裁判所
The highest court, and the court of last resort on whether any law, order, regulation or official act conforms to the Constitution (Article 76, paragraph (1), and Article 81). That power is what makes the Constitution enforceable: there is no penalty attached to breaching it, and instead a conflicting rule is held to have no legal force (Article 98, paragraph (1)). Its judges are reviewed by the people at the first general election after appointment, and again after ten further years (Article 79, paragraph (2)).
