Abstract
The Japanese maritime industry has been transformed to a smaller size; fewer Japanese seafarers and more non-Japanese flag carriers since 1985. This transformation has led to today a lack of Japanese pilots, and the lack of them is the first to appear in Japan. At the same time, Japan's Ministry of Land, Infrastructure and Transport started a new pilot education and training courses from beginning April, 2007. On the other hand, a few researchers had published their papers about pilots and pilot systems in Japan. It is obvious that the pilot system has been sustaining Japanese economy. The Japanese pilot system is changing within one decade, so it is necessary for us to study about pilots and their systems. The purpose of this paper is to study about occurrence tendency of pilots' collision incidents in Japan, especially for the Kanmon Pilot District. At first step, we focus the district and divide it nine zones and four lanes for plotting the position of those incidents. We count plotted points for each zone and lane. Of special focus are current directions and ships situations between two collided ships. We propose how to divide the Kanmon Pilot District and how to study occurrence tendency of pilots' collision incidents in the district.
