In the revision of the Flood Control Act in 2015, it is obliged to set the flood danger water level for storm surge. However, it is unknown that how often actual tide level reaches the flood danger water level since the flood danger water level vary according to lead time. In this paper, numerical simulation of possible maximum storm surge is performed and flood danger water level is set on the coast in Aichi Prefecture using simulation results. Comparing flood danger water level with observed tidal data in Port of Nagoya., it is confirmed that flood danger information of storm surge is not often issued and that the flood danger water level can be reached about once in four years assuming that storm surge coinsides with normal high tide.
