Summary:The transport network in eastern Japan was severely damaged by the Tohoku Earthquake in 2011. The coast of Iwate Prefecture was severely affected by the tsunami. Because of the different topography, we think that the road recovery situation of Iwate Prefecture should be very different from the two prefectures studied previously. In this study, we analyzed the data of vehicles driving in Iwate Prefecture to classify the road recovery condition among municipalities in the first six months after the disaster. The results of the cluster analysis show that the road recovery condition is similar according to damage, recovery policy, importance of the road and population density.
