Abstract
A past study by the authors proposed a method to estimate maritime freight flows using metric tons and the twenty-foot equivalent unit (TEU). In order to clarify the accuracy of the estimation method, this paper describes the characteristic of the existing freight flow statistics shown in Japan, Indonesia and Hong Kong, and the characteristic of the estimation results for those three countries/regions. From the relation between the characteristic of statistics and the characteristic of estimation results, the authors show that the accuracy of the estimation results is not different from existing statistics.
