The possibility of a huge earthquake striking Tokyo in the future is high. In the event of such an earthquake, many people will face problems such as the inability to return to their homes, which will cause complete disorder and confusion in the city as it will be impossible for everyone to access emergency shelters. If buildings remain safe, it will be desirable for residents to take refuge at home. In this study, we investigated the disaster awareness of 461 residents in central Tokyo using an internet survey. Our results reveal that approximately 60% of residents expect to take refuge at their own homes. However, almost none of the respondents have emergency supplies such as water, food, and other daily necessities. This lack of preparedness could result in many people having to move to emergency shelters when disaster strikes. By analyzing these results, we aim to develop a method for avoiding confusion in the aftermath of a disaster and educate building residents on their needs and the preparatory actions they must take in such situations.
