It is essential that transshipment at Naha Port enjoy the benefit of economy in container
logistics. China's economic growth has led to a phenomenal increase in the container traffic of the East
China region, and that growth is expected to continue. The NPA's challenge is to divert just a
small portion of these containers from the direct shipping pattern along China's coast to the
Naha transshipment pattern. Shipping companies can reduce the turnaround time of mother
vessels, which in turn will lead to a reduction in the number of huge, expensive mother vessels
for both U.S. and Europe trunk lines. The NPA estimates that the Naha transshipment pattern is
cost competitive with the direct shipping pattern, even including transshipment costs at Naha.
