Recently, in Japan, we promote the measures for tsunami as we keep local tsunami with strong shock in mind. But the measures for distant tsunami with weak or no shock are not enough. In such situation, the earthquake of the Chishima Islands occurred on November, 2006, and tsunami warning was issued. In this earthquake, there are many issues like distant tsunami. In correspondence of administrations, 1) the prior measures for tsunami are not enough in the areas that have't experienced a tsunami till now, 2) whether the prior measures for tsunami are carried out or not influence correspondence of inhabitants. In correspondence of inhabitants, 1) the evacuation rate of inhabitants was low in the areas that have experienced tsunami and was high in the areas that have't experienced tsunami till now, 2) these causes ware the size of shock of earthquake and the experience that tsunami didn't hit in spite of the issue of tsunami warning, 3) the evacuation rate of inhabitants fell remarkably by only once experience of false alarm of tsunami.
In this paper, we pointed out that promotion of disaster preventions for tsunami of the areas that they are not enough till now and promotion of the prior measures for disaster preventions for tsunami ware necessary, and improvement of inhabitant's tsunami information literacy that was higher than the literacy of local tsunami was necessary.
