The 2014 Ontake eruption and the 2011 Great East Japan Earthquake resulted in some revision of government measures for disaster prevention. The role of residents in disaster prevention is increasing. The effectiveness fusing of tourism with disaster prevention education in the disaster prevention system is confirmed in some volcanic areas. This paper focuses on the background to the rapid evacuation during the 2015 Kuchinoerabujima volcano eruption as a case study focusing on disaster prevention action and daily disaster awareness of volcanic activity. The case of the 2015 Kuchinoerabujima eruption shows that it is important to enhance relationships not only among experts, local government, residents, and the media but also among experts and non-expert residents who have an interest in volcanic activity. In Kuchinoerabujima, based on the proven program of nature study abroad, the effectiveness of fusing tourism with disaster prevention education in the disaster prevention system is confirmed. Cooperation between tourism and disaster prevention is important for the safety of visitors and the safety and livelihoods of residents.
