Japan has maintained political stability since 1955. The Liberal Democratic Party (LDP) has dominated the Diet, monopolizing the position of a ruling party since its foundation in 1955. Political processes in the Diet and administration were established on the basis of the single party dominance by the LDP, and for more than 30 years they did not suffer from fundamental changes. Japanese politics gave ‘the impression of stultifying immobilism’ (Stockwin 1988: 325). Such stability, however, was shattered after the general election of July 1993.
