    This study focuses on the psychological effect of seawalls on residents’ risk perception and evacuation behavior related to a tsunami disaster. A questionnaire survey was conducted in two adjacent areas, with and without seawalls, in Shizuura, Numazu City, Shizuoka Prefecture. Most of the 311 residents who answered the questionnaire were aware of tsunami risks. However, residents who lived behind a seawall were less likely to read the hazard map carefully (p<0.05) and determine an evacuation place beforehand (p<0.05). In addition, they were less likely to evacuate during tsunami (p<0.01) and would not consider evacuating unless a higher tsunami was expected (p<0.01). These facts indicate that seawalls affect residents’ risk perception, preparedness, and evacuation behavior related to tsunamis.
