This article examines how the Japanese electorates' voting behavior changed between the 2001 and the 2004 Upper House elections under the Koizumi Cabinet, by looking at the role of retrospective evaluations of the cabinet, based on the JES III data.
The results of the analysis revealed that the effects of retrospective evaluations on the voting behavior increased from 2001 to 2004. We also found that the impacts of the evaluation of the Cabinet's foreign policy were clear and consistent through the elections; however the evaluation of the Cabinet's economic performance exerted much weaker influences. The disbanding of the “Koizumi Coalition” is also discussed.
