Considering flood-control measure on underground area is very important matter for the Japan of today. In this paper, we simulated some type of inundation and evacuation activities affected by the depth of water in a underground station. In this study, we clarified the time when each exit become unavailable, and that there is the exit which has a great influence on the time taken to evacuate. According these simulation results, it becomes clear that strategic evacuation guidance based on the flood situation is very important for safer evacuation.
