This book examines how the internationalization of corporate activities has affected the commercial policy preferences of Japanese corporations. Using case studies of three industrial sectors and of Keidanren (Japan's most influential business federation), the author argues that growth of international operations is one of the major reasons why internationally oriented firms and their main business federation have committed themselves to promoting the opening of keiretsu groups, and to promoting market access for foreign firms and products. The book includes much new and valuable information about business-government relations, political conflict and policy making and implementation processes in Japan.
