The Democratic Party of Japan said Tuesday it will issue constitutional amendment proposals by 2006.
Naoto Kan, president of the nation's largest opposition force, made no specific references to changing Article 9 of the Constitution, which prohibits Japan from using military force as a means of solving international disputes.
He did suggest, however, that the DPJ may advocate the establishment of a special reserve force to fulfill overseas police missions at the behest of the U.N. or similar international bodies.
