We carried out damage investigation around the seismic stations where high JMA seismic intensity scales were recorded in the 2019 off Yamagata Prefecture Earthquake. We found some minor damage such as damage to the outer wall and the roof tile, but heavily damaged buildings were not found around all the seismic stations. We investigated the correspondence of strong ground motions with damage to buildings. Short period below 1.0 s was dominated in most the strong ground motions and the 1-1.5 s response which has close relationship with heavy damage to buildings was small, therefore, heavily damaged buildings were not found in spite of high JMA seismic intensity scale. The buildings damaged to the roof tiles were found around many the seismic stations because the damage to the roof tile was correlated with the short period below 1.0 s.
