Nikkei wrote that it obtained on Monday a proposal drafted by the Democratic Party for the People concerning a review of the U.S.-Japan Status of Forces Agreement. The opposition party proposes that Japanese authorities should be allowed to exercise their right to investigate off-base accidents and incidents involving U.S. military personnel in view of the current situation, under which their right to investigate is restricted when the U.S. military takes custody of suspects. The paper wrote that the party plans to call on other opposition parties to adopt its proposal as a common campaign platform for the Upper House election next summer.
