Due to the recent imbalance in trade between U. S. A. and Japan, there is a strong political opinion in the U. S. A. to ask the government of Japan to open the domestic construction market to American contractors. The opening of the domestic construction market to American contractors will enormous effects on many fields of Japanese construction. Therefore, it is quite important and indeed necessary to study the principles relating to these differences between the Japanese and overseas construction industries.
Such principles will be clearly explained in “Management Style Theory” which has been developed in the U. S. A., and also the application of “the Theory of Psychological Types” established by the famous Swiss psychologist, C. G. Jung.
