Authors asked 1159 captains and pilots for subjective assessment on risk of navigation in 33 Japanese sea areas including main harbors, straits and coastal zones by a questionnaire. They also asked the reasons why they felt it at the same time. Based on the results authors ranked these sea areas in the risky order from view point of safe navigation and made a statistical analysis of them using cluster analysis technique and factor analysis one. The results indicated the navigation in the congested sea areas were more risky for mariners comparing with those in the harbors and the coasts. They succeed in clustering the sea areas based on the risky factors for navigation and extracted the main four groups of risky factors. They finally proposed that we should individually provide measures for safe navigation in each waters based on the results of such risk analysis there.
