In case of tsunami evacuation, on foot is principle in Japan based on several lessons from the past. However, there is a tremendous need for tsunami evacuation by a car in coastal area where no high ground including high building is found. This paper aims to design a new tsunami evacuation plan with combination of walking and cars in Watari town. The major reasons of car evacuation need is no high safe zone and far out of inundation area in coast. As a result of primary simulation, it is found that 46.0 % people in tsunami inundation area of the 2011 Great East Japan Earthquake disaster cannot escape from tsunami on foot. We propose a flowchart which select tsunami evacuation transportations (walk or car) and suggest directions (horizontal or vertical) for each district, and suggest an evacuation plan combination of walking and cars.
