We report the investigation of the indoor damage and the questionnaire intensity for the high-rise university building in Tokyo during The Great East Japan Earthquake (Mw 9.0). The strong ground motions were observed around East Japan by this earthquake, the high-rise buildings experienced the unprecedented strong motions. However, this ground motions are smaller than the estimated scenario ground motions which are caused by Tokyo Metropolitan Earthquake and Tokai and Tonankai Earthquake, this earthquake caused the indoor damage to the high-rise buildings. Therefore, to get ready for the next great earthquake such as Tokyo Metropolitan Earthquake and Tokai and Tonankai Earthquake, we investigate our university high-rise building and correct the indoor damage and questionnaire survey.
