The purpose of this study is to investigate the feasibility of survey that clarify the number and location of shipbuilders in Nagasaki Prefecture. We use survival analysis with data obtained from published statistics and shown on yellow pages. For that, we made surveys from August 2006 to January 2007 continuously. We use statistical environment R (Version 2.6.1) for analysis and drawing some figures such as. The results demonstrate three characteristics of the shipbuilders. First, most of shipbuilders in the prefecture build fishing vessels mainly. Second, the number of them has decreased for these 30 years. Third, they are located intensively around Nagasaki city and Tsushima city. In addition, it is useful to use contents in yellow page as a data source, especially for GIS. Our data indicates that the location and the number of shipbuilders seem to be dependent on spatial factor, such as the way of fishing. And as a result of their decline, we worried about the capability for creating new ship form would be lost. Anyway, we conclude that we have to approach the industry from the viewpoint of ship itself, which is main product of shipbuilders.
