Katase-Nishihama and Kugenuma District is known as one of the most congested bathing beach in Japan for summer busy season, which confronts tsunami evacuation problems not only for residents but also large number of visitors. Based on multi-agent simulation method, this paper aims to quantitatively clarify refugees' evacuation behavior and average evacuation time in different scenarios and to suggest some solutions, such as construction of elevated railway for the Odakyu-Enoshima line, to reduce tsunami evacuation risk, especially for the visitors. As a result, the elevatedd railway construction will enable more than double number of evacuees to escape from a future tsunami estimated by the 1605 Keicho Earthquake.
