Japan, 1955–1972
Democracy · Monarchy · East Asia · Détente Era era
Postwar constitutional democracy under the "1955 system" of Liberal Democratic dominance, delivering the high-growth economic miracle while renouncing war under a pacifist constitution.
Under the 1947 pacifist constitution, postwar Japan built a stable parliamentary democracy dominated after 1955 by the Liberal Democratic Party. Competitive elections, an independent judiciary and a free press coexisted with close bureaucratic–business coordination that drove the high-growth "economic miracle". The US alliance anchored security while Japan renounced war and kept military spending low.
