The objective of this paper is to examine the structure of trust on organizations of the East Asian countries and the possibility of a cross-national comparative study, using data analysis of the East Asia Value Survey. Multiple Group Analysis and Categorical Principal Component Analysis are principally used in this study. This paper first examines the structure of trust in organizations. Two findings were made. Two types of common factors (establishment trust and civil trust) can be assumed. In addition, these factors can only be considered completely the same either in mainland China or in Japan, Korea, Taiwan and Hong Kong. This paper also investigates whether trust in individuals can explain trust in organizations. Results indicate that trust in individuals cannot alone explain trust in organizations. This suggests the need for synergy trust in organizations.
