For the analysis of the currents at the near shore area of Toyama, the time domain dates have been observed by the water bottom setting type 1200kHz ADCP, which the observation layer is 0.25m. At the river mouth of Shogawa river, the presence and structure of the salt water wedge was observed. And, at the coasts of Namerikawa, Ebie and Himi, the 2-5days ADCP observations have been done. As the results, the speed was about 0.1-0.2m/s at the whole area and tidal and wind drift currents are observed.
