The Liberal Democratic Party: Its adaptability and predominance in Japanese politics for 60 years

This article discusses the origin and continuity of the predominance of the Liberal Democratic Party (LDP) in Japanese politics since the party's formation in 1955. The LDP experienced two crises in its history, the first owing to the transformation of Japanese society by rapid economic development during the 1960-1970s, and the second due to the electoral reform in 1994 and the challenge from the Democratic Party of Japan thereafter. I argue that the LDP's continuous success is attributable to its adaptability to new environments: the party overcame the first crisis by shifting the policy focus, reorganizing its support base and the party organization to achieve intraparty consensus. It coped with the second crisis by forming a coalition with the Clean Government Party and reforming the party's presidential election and the ministerial post-allocation system. The article concludes with a summary and a brief discussion regarding the future of the LDP.
