Recently relative position of port in Japan has been lower than ports in Asia. Therefore, the number of the fundamental route which calls at a port of Japan are decreasing. Thereby, the problem of the increase in a lead time or the increase in logistics cost occurs.
Then, Japanese government has carried out development policies for some ports in Japan since 2002. But the number of the fundamental route which calls at a port in Japan continues decreasing from 1998.
In this study, we analyze the cause of decreasing of the number of call in the fundamental route of a container service. In addition, we discuss about the case of adding Tokyo port to the existing fundamental route.
As a result, handling time increases by enlargement of a container ship. And in order to maintain weekly service, we found out that it is necessary to increase the number of ships. Thereby, in order to reduce expense, it turned out that a shipping company reduces the number of call and fixes the number of ships.
Moreover, in order to stop a fundamental route at the Tokyo port, it turned out that shortening of handling time etc. is effective.
