Abstract
On March 11, 2011 a great earthquake with a magnitude of 9.0 occurred off the Tohoku Japan, and great tsunami attacked the coasts in Sanriku Region and Sendai Bay, causing large disaster. Although the tsunami height was different from place to place, many shrines built near the coasts were escaped from being destroyed by tsunami except several cases and they were used as an effective area for the evacuation of the people. We investigated the reason in terms of the tsunami height and the ground elevation of the shrines.
