A questionnaire survey was conducted at three sea bathing places having different attributes on recreational users to investigate the user's consciousness for Tsunami disaster mitigation. It was cleared that the attributes of both recreational user's age and distance from user's dwelling place to the beach strongly affect the structure of consciousness for Tsunami disaster mitigation. The consciousness for Tsunami disaster mitigation tends to become lower in younger age groups. Also, recreational users visiting from distant places show lower consciousness for Tsunami disaster mitigation than the users near the beach. Through this investigation, it is implied that the education about Tsunami disaster mitigation is important especially for younger age groups. Furthermore, this study suggests the importance of giving effective information about Tsunami disaster mitigation to the recreational users from distant places in order to notice the dangerousness of Tsunami disaster at the beach.
