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).
