The maximum magnitude of this earthquake was recorded 6.8 and the maximum JMA seismic intensity scale was recorded 6 upper, and Chuetsu area, especially around Kasiwazaki city, was damaged extensively. The Tsunami was occurred due to the earthquake, however arrived to Akita and Ishikawa shoreline. This wave was not big and there were not the extensive damage this time. However, the big tsunami following the extensive damage sometime occurs in the Sea of Japan. For example, the Tsunami due to Niigata Earthquake in 1964 became over 4 m wave height at Niigata City. Therefore, even if it was a small-scale wave and small damaged in this time, it is necessary to analysis how the people on the beach when the earthquake occurred thought, for example, how they imaged the arrival of tsunami and how to evacuate from the tsunami. Then, this study researched the hearing investigation for the people who was near from the shoreline when the earthquake occurred. The results mainly indicate that the more any evacuation route information should be shown, because the most people who come from another place do not know the information.
