The central areas of the Kanmon strait which are the object of this study are greatly congested with shipping traffic and fishing operation, and marine accidents have been occured frequently. Therefore, the survey of the shipping traffic condition was carried out from 31 May to 3 June 1978, using shipborne radar, cinecamera and visual observation. It becomes clear from the results of the survey that nearly 90% of the navigating ships are those less than 1, 000 gross tons, considerable number of ships navigate along the illegal route at the winding part of the passage and the approaches, and sometimes, the line fishing boats are carried away to the inside and the vicinity of the passage by wind and current. On the basis of the survey results, the shipping traffic improvement plan is discussed about the preparing of navigational aids for ships passing through the passage and the arrangement of the fishing operation.
