In Hirosaki City, Aomori Prefecture, due to heavy rain caused by “Typhoon No. 24 in 2018 ”, the “evacuation advisory” was announced for the first time after the designation of the sediment disaster (special) warning area. Therefore, we conducted a questionnaire survey targeting fire volunteers and residents in the sediment disaster (special) warning area. Then, we considered the recognition of evacuation information regarding sediment disasters. As a result, it was clarified that the knowledge of the residents living in the sediment disaster (special) warning area about the sediment disaster leads to the recognition of evacuation information but not to the eviction evacuation. In addition, “disaster prevention education”for fire volunteers is expected to lead to prompt evacuation guidance for residents.

In 2020, Typhoon No.10 (Haishen) moved rapidly northward in Kyushu’s western sea and strong winds occurred on the eastern side of its track. This typhoon was a typical “wind typhoon”, which caused little rain in Northern Kyushu along the Suonada Sea coastal area. Especially along Suonada Sea coastal area in Yamaguchi Prefecture, precipitation was low, at only 10.0 mm in Shimonoseki, 9.5 mm in Ube, and 13.0 mm in Hofu. As a result, damage by the infiltration of seawater occurred, including the browning and defoliation of Ginkgo trees on the windward side and the browning of ears of rice (i.e., Hinohikari) planted late in the paddies on reclaimed land.

Heavy rainfall associated with the 2019 Typhoon Hagibis caused an inundation disaster in the area located on the border of Setagaya and Ota Wards and surrounded by three rivers, Tama, Yazawa, and Maruko Rivers. In order to gain a concrete understanding of the progression of inundation and people 's behavior during the inundation disaster in this area, footage from a security camera recording the situation at a certain crossing in the area was analyzed. With regard to the progression of inundation, the temporal change in the inundation depth and the occurrence of the water flow were identified. With regard to people's behavior, the traffic situation of cars and pedestrians and the walking speed during the inundation were identified. Referring to the findings from past disasters and experimental studies, it is considered that the inundation situation at the crossing reached a condition that made movement hazardous for both cars and pedestrians.

When a subduction-zone earthquake, such as the Nankai Trough Earthquake, occurred and tsunami arrival time is limited in coastal tourism areas, all the people, including residents, tourists, and tourism workers, must immediately evacuate any safety zones. In the emergency state, tourism workers could play vital roles in supporting tourists' evacuations. This study explores the relationships among tourism workers' perceptions of supporting tourists including perceptions of the issues, perceived behavioral control, responsibility perceptions, and behavioral intention during the emergency period following the Nankai Trough Earthquake. Respondents' attributes and risk perceptions of seismic ground motions and tsunami of the Nankai Trough Earthquake are also identified, and differences of perceptions of supporting tourists' evacuations in these items are analyzed. The research site is Shirarahama area in Shirahama Town, Wakayama, Japan which is a famous tourist and tsunami-prone area. A questionnaire survey targeting tourism workers was conducted in the estimated tsunami inundation zone of the Nankai Trough Earthquake. In the analysis results, the perception of issues in information communication with tourists was an essential factor for decreasing perceived behavioral control. Results also indicated that responsibility perceptions for supporting tourists are largely affected by perceived behavioral control for assisting the evacuations of vulnerable people.
