 OBJECTIVE: To determine escape delay from a tsunami of mentally disabled people registered in a tsunami inundation prediction area using GIS in an employment support room for individuals with disabilities.

 METHODS: With this survey using the K-DiPS sheet, I investigated 24 mentally disabled people living in a tsunami inundation prediction area for a Nankai Trough earthquake.

 RESULTS: Four of the five local welfare evacuation centers were located in a tsunami inundation prediction area. Following simulation of evacuation behavior, I concluded that one of the 24 subjects would be blocked while trying to escape. I believe the cause was a poor choice of evacuation route. Trying to move to welfare evacuation centers may increase the risk of hindered escape.

 CONCLUSION: Owing to the negative feedback effect, if the location of a welfare evacuation center is specified and an announcement about the need to evacuate is made, it is possible that evacuees will head toward the influx of the tsunami. Therefore, to prevent accidents at such times, it is necessary to consider geographic factors, such as the position of the designated welfare evacuation shelters, flood depth, tsunami flow direction, and the distance to the welfare evacuation shelters.
