The tsunami which run-up in river over the embankment affected serious damage in coastal area at the 2011 Tohoku earthquake and tsunami. Therefore the measures to river run-up of the tsunami were important in thinking about the tsunami disaster prevention in the coastal area. On the other hand, there were few records of the tsunami data, though active faults were near the land on the Sea of Japan side and time to tsunami arrival from an earthquake occurrence tends to be short. Therefore it was simulated based on 1983 Japan Sea Earthquake to perform the comparison with the measured value with Sea of Japan side particularly.
