1.The Constitution of Japan
The Constitution of Japan, successor to the Constitution of the Empire of Japan (1889; also known as the Meiji Constitution), was promulgated on November 3, 1946, and took effect on May 3 the following year. Consisting of eleven chapters with a total of 103 articles, it is based on the following three principles: sovereignty of the people, pacifism, and respect for basic human rights. The first principle is explicitly stated in the preamble: "We, the Japanese people, ...do proclaim that sovereign power resides with the people and do firmly establish this Constitution." The Constitution defines the emperor as the symbol of the state and of the unity of the people, and provides that the emperor shall have no powers related to government, acting only in certain matters of state.(*1)
In January 2000, the Diet established a Research Commission on the Constitution in both the House of Councillors and the House of Representatives for the purpose of discussing the process by which the present Constitution was formulated and its problems. The Commissions were mandated to reach a conclusion within about five years' time. They have no powers, however, to submit bills to the Diet. In November 2002 the House of Representatives' Research Commission submitted an interim report on its deliberations, containing arguments both for constitutional revision and for maintaining the Constitution in its present form.
In September 2003, Prime Minister Junichiro Koizumi pledged that his own Liberal Democratic Party will draw up a reform draft by 2005 when the ruling party celebrates the 50th anniversary of its founding.(*2) Naoto Kan, who leads the Democratic Party of Japan, the nation's largest opposition party, also proposed drafting by 2006 a plan for constitutional amendment at the party's January 2004 convention.(*3)
