The authors have analyzed various features that characterize Prime Minister J. Koizumi’s rule. Particular attention is given to the measures taken by his government to overcome economic stagnation, first of all radical reforms in the sphere of finance and in the corporate system. A major part of the book deals with the political struggle waged by J. Koizumi against the opposition within his own party and beyond. The authors have also estimated the results of Koizumi reforms and have made an attempt to forecast Japan’s future under the rule of his successors.
