The ascendance of the Democratic Party of Japan (DPJ) on August 2009 was praised as the first genuine power transition in Japan’s postwar history. However, there were just as many—or more—who were anxious about the new DPJ-led Japanese government’s capacity to govern. After all, the Liberal Democratic Party (LDP) had dominated most of the five decades of Japan’s postwar history as the ruling party. The sole role of the opposition parties, including the DPJ, was to criticize the policies presented by LDP-led governments. It was obvious, therefore, that the DPJ would be inexperienced at ruling. The question was how long it would take before the DPJ grew to become sufficiently able to play the role of a ruling party.
