This volume presents an analysis of Japan's powerful upper bureaucracy in the post-war period. The author’s aim is to provide an empirical foundation for the many impressionistic accounts of Japanese bureaucracy and a systematic basis for comparative studies of bureaucracies in other countries. The study ranges from the family and geographic backgrounds of higher civil servants through their educational training and career patterns to their retirement and post-retirement activities. Throughout, the emphasis is on assembling and analyzing the kind of systematic data that provide a solid basis for understanding how the Japanese bureaucracy actually works.
