I. The Japanese Diet under The New Constitution**

From the standpoint of the national legislature, the constitution of Japan which became effective on May 3, 1947, contains the following significant reforms: (1) popular sovereignty replaces the sovereignty of the emperor; (2) the Diet is the chief branch of government; (3) an elected House of Councillors supersedes the House of Peers; (4) the cabinet is responsible to the Diet; (5) the “invisible government” of crown agencies is abolished.The preamble to the new constitution begins: “We, the Japanese people, acting through our duly elected representatives in the National Diet…, do proclaim that sovereign power resides with the people.” As for the once sacred and inviolable emperor, he does “not have powers related to government,” but functions merely as “the symbol of the state and of the unity of the people, deriving his position from the will of the people with whom resides sovereign power,” performing, “with the advice and approval of the cabinet,” only such acts as promulgating laws, convoking the Diet and dissolving the House of Representatives, proclaiming general elections, attesting the appointment of officials, and awarding honors.
