The New Nagasaki Fishing Port has been completed up to the stage when it can work as a fishing port. We studied the projected ship traffic after 8 years from the opening of the port. We made the following conclusions conceming traffic congestion : 1. The number of fishing boats using the New Nagasaki fishing port will decrease. Futhermore, the largesized ships will make less than 10 % of the traffic. 2. Construction of new offshore breakwater allows to increase number of small-sized fishing boats passing inroute C. 3. The breakwater affects the visibility for ships arriving from the west entrance. So, more careful navigation is requested.
