Abstract
This study examines the implementation of tsunami countermeasures in local governments after the Great East Japan Earthquake, with focus on Hamamatsu City, Shizuoka Prefecture, as a study area. Hamamatsu City in Japan implemented the regional development promotion plan for tsunami disaster prevention and tsunami evacuation plan against the megathrust earthquake of the Nankai Trough. In addition, Hamamatsu city developed hard countermeasures, such as the construction of tsunami seawalls in coastal areas and the construction and expansion of tsunami evacuation facilities, as well as soft countermeasures, such as action plans for community evacuation based on regional characteristics. The trends of the tsunami countermeasures in Hamamatsu City linking public help with self-help and mutual help can be useful for other local governments.
