Disaster information collecting dissemination using SNS in the event of a disaster has become active in practical and academic discussions since occurring the 2011 Great East Japan Earthquake in Japan. In this paper, we investigated the recent situation regarding SNS usage trends of disaster survivors and clarified the features and issues. The main results are as follows. 1) Even 10 years after the 2011 Japan disaster, about 70-80% of TVs and about 40-60% of radios were the main means of collecting information in the disasters. LINE and Twitter as SNS tools have become the main collecting media following TV and radio, accounting for about 20-40%. 2) Only about 20% of the survivors send information using SNS in the disasters. The transmission is mainly done by LINE. 3) About 30% of the survivors had the experience of receiving troublesome information from SNS during disasters. The information that was particularly troublesome was not factual information, but incorrect information (including hoaxes), received information that caused anxiety, and too much information, making it difficult to determine the necessary information. That was, the information was updated remarkably, and they saw information that had nothing to do with the disaster.
