Field survey and GIS analyses were made to clarify the present status and problems of 50 tsunami shelter buildings, which have been specified by the Shizuoka city office. We examined the situation, appearance, age of construction, and facilities of the shelter buildings using a checklist, which is based on the guideline of tsunami shelter buildings (Cabinet Office of Japan, 2005). We also made DEM from elevation data on base maps for city planning. All these data, as well as the data of estimated flood areas by tsunami of the Tokai Earthquake and the data of population density, were input to GIS and their spatial distributions and properties were compared with each other. Main results are as follows. Number of the shelter buildings is insufficient and their distribution is not effective in several areas. About 30% of the shelter buildings are locked and keys are necessary even in urgent situations. About 55% of the shelter buildings were constructed before 1981 and have problems of seismic capacity.
