A huge disaster due to tsunami occurred on 11th March 2011 in Japan. The tsunami's height reached 14m, and the lower areas of coastal cities and towns were completely wiped out and buildings function were lost. Many drowned people have not yet been found. Other great tsunamis are expected in the near future in coastal areas of Japan. The tsunami load on these building could be estimated as a hydro pressure against surface of drift direction. It is pointed out that the collapse load factor according to the design criteria for the building other than the rim of the coastal area may be given a good estimation of building safety.
