Over the past thirty years, Asian regions have achieved continuous economic growth, which has brought an increase in the volume of cargo handled at ports in Asia. During the process of economic growth, ports require smooth handling for import/export products and materials. Additionally, it was considered that investments to ports be ‘appropriated’, to ensure that ports can handle increasing amounts of cargo efficiently, in the countries sustaining economic growth such as NIEs and so-called New NIEs (Page 10). Regarding the New NIEs’ port developments, financial and technical support from international organizations such as the World Bank and the Asian Development Bank as well as individual nations, played important roles. However the Government of Japan contributed uniquely to these Asian countries’ economic growth through Japan’s ODA, with the point of view that a port is a basic infrastructure for economic and regional development (Page 12). Meanwhile, the results of Asian countries’ economic growth have promoted the horizontal division of work in regional areas. Other countries’ economic growth has been the essential factor for our home country’s growth too. Our country is no exception to this situation. the ‘Asian Gateway Initiative’, pledged by the Abe administration, is also considered to be framed as a factor of these realities which require us to make decisions about Japan’s strategies based on the interdependent relations among regional countries. Regarding the port sector supporting business activities of Japanese companies, efficient international physical distribution is necessary, and significance of the international cooperation which Japan has been undertaking requires serious re-evaluation and adjustment too. These features are lined up on the basis of our assumption mentioned-above. All the writers prepared documents of their own ideas considering the ports supporting Asian economic growth with international cooperation. We would appreciate it if the articles assist your recognition of the Japan’s ODA and international cooperation for the port sector deeper than before and that you may understand its necessity for internal performance.
