Roughly 60 percent of the 107 municipal assemblies nationwide that have approved or adopted nonbinding statements regarding the revised Japan-U.S. defense cooperation guidelines and related bills have called for amendments or abolition, according to results of a survey released Thursday.

The 107 assemblies span 21 of the nation's 47 prefectures, and those expressing opposition said in their statements that it is unconstitutional to make it obligatory for local governments to cooperate with the central government when implementing the guidelines and related bills, which have already been submitted to the current Diet session.

These assemblies also noted that such local-level cooperation would greatly affect citizens' daily lives, according to the survey conducted by Kyodo News.
