The book uses an original language-based bilayer theory to throw light on the secretive structure of power in the Japanese Diet, its national parliament, and relates its findings to Japanese parliamentary democracy in historical perspective. In so doing, the book answers questions about the latent policymaking process of Japanese politics that resulted in a reduction of social alienation and disorganization while Japan industrialized. Industrialization significantly reduced poverty and increased the size of the middle class, enabling the nation to move towards democracy. The reader will see why socialists were so quixotically dogmatic toward conservatives to the point of absurdity during the Cold War period. Yet, they were able to form a coalition government following the end of Cold War era.
