While some writers account for Japan's postwar economic "miracle" in terms of a distinctively Japanese, traditional model of social organization, the writers of this study consider Japan's technological growth to have been accompanied by convergence toward modernized social organization. The authors test both of these theoretical models. Their data are derived from a nine-month period of observation, analysis of company records, interviews of personnel, and questionnaire responses from production, staff, and managerial employees in three main Japanese firms. Other firms were visited more briefly. The analysis shows that the most distinctively Japanese variables have less causal impact on performance within a firm than do more universal variables such as employee status, sex, and job satisfaction.

Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
