Based on the field investigation of the 1946 Nankai Earthquake Tsunami in Asakawa, Tokushima Prefecture, the characteristics of inundation heights and the water current on land were investigated. Furthermore, the life risks and the degree of damage to houses by tsunami in Asakawa were discussed in detail. As the result, the following conclusions were drawn : (1) The inundation heights above the Mean Sea Level were in the rage of 5.5-6 m at Ohta, Miura and Ina-higashi districts. (2) The distribution of the water current vectors of the inundation area could be fairly well reproduced by the present analysis. (3) The life risk level by tsunami in Asakawa was almost equal to that of death by traffic accidents in Japan. (4) The condition of damage to houses might be estimated by knowledge of inundation heights and the water velocities on land.
