Naha Airport in Okinawa is striving to become a new logistics hub in Asia and is preparing for an expansion in trade expected if the Trans-Pacific Partnership deal takes force.

One day in late June, the airport in the prefectural capital shifted into business mode at around 1 a.m. with the arrival of an ANA Cargo Inc. cargo jet.

The cargo was transferred to delivery firm Yamato Transport Co.'s sorting station in the freight terminal and then grouped by final destination, such as Singapore and Hong Kong.
