For the last few years, ships' traffic investigations on the narrow channels or straits are being pursued closely in Japan. And the useful informations help us to know the actual conditions of the ships' traffic in those waters. But the actual observations and studies of the ships' traffic in the coastal waters have not been conducted before in Japan. We must leave these for a future studies. In this type of the studies we need many informations and the choice of the method to collect the informations is in itself a problem. Here we introduce some of our recent studies by the photographic recording method of the radar screen. The recordings have been obtained from the voyage along the coast from Tokyo to Kobe, covering the distance of about 370 nautical miles. Further studies will be left over to the future. The summary reports are as following. 1. The photographic recording method of the radar screen will be a great help in collecting informations. 2. The average number of the ships within a radius of ten nautical miles was more than 30 in the above mentioned area. 3. The main or congested area of the coastal route and its width were somewhat observed.
