    Proper action of evacuating from tsunamis is essential to reduce human loss due to tsunami after the eartthuqake. Accodinrg to previous studies, disaster information, recognition and experiences about the past tsunami disaster and preparation for tsunami before the disaster and risk perception for tsunami would be factors influencing evacuation behavior. This paper aims to clarify which factor should affect on evacuation behavior in the 2011 Tohoku earthquake using comprehensive analysis on results from questionnaires at Kesennuma city. It is indicated the risk perception for tsunami as the most effective factor on time starting evacuation. The risk perceptions should consist of internal (personal) and external triggers which are future topics to be clarified.

    Housing in Thailand is expanding to the suburbs, especially for the lower classes, with more people living in collective housing. This study used a questionnaire survey to analyze the relationship between socio-economic disparities in collective housing and disaster risk reduction following the 2011 great flood. The results show that although suburban lower-class collective housing was severely affected by the flood, DRR measures remain insufficient. The findings suggest that in addition to supporting victims irrespective of residential status and aiding apartment managers to implement DRR measures, lowering levels of inundation in the suburbs by “sharing” flood water with the more affluent city centers is an option that needs to be considered.

    In the Mw9.0 2011 Tohoku, Japan, earthquake, high-rise buildings located in Tokyo and Osaka, far from the source zone, were shaken by long-period seismic ground motion. In this study, vibration characteristics of a high-rise building located in Osaka Bay coast were investigated using seismic records obtained in the 2011 Tohoku earthquake and other events. The natural periods, participation functions and damping ratios were identified based on the fitting of theoretical transfer functions by observed Fourier spectral ratios. Through this identification, the change of modal parameters of the building in time due to structural nonlinearity and seismic retrofitting were recognized. Finally, the prediction of seismic response due to the scenario Nankai-Trough earthquake was performed.

    This paper reports relationships among visitor characteristics, awareness of disaster prevention in normal times, and evacuation behavior in a tsunami situation on the beach. We conducted an interview survey on five beaches in Wakayama City. The contents of the survey included awareness of disaster prevention in normal times, knowledge of disaster prevention, and evacuation behavior in the event of a tsunami. We clarified the following points. Elderly visitors are very aware of disaster prevention and have considerably more knowledge of disaster prevention than young visitors. Visitors who had experienced evacuation drills evacuated more quickly than others. Visitors who saw an evacuation guidance signboard tended to evacuate on foot.

    We collected efforts of disaster prevention awareness relating to foods which have been implemented all around the country. And we focused on Hamaguchi Goryo, the main character of “Inamura-no-hi ” as an effort to cultivate public awareness about disaster prevention among youths and women, developed dishes featuring Hamaguchi Goryo. Then, we offered those dishes at a hotel in Choshi City, Chiba Prefecture, and analyzed those effects and issues from impressions of participants of the program. As a result, we were able to confirm the effects relating to cultivation and heightening of consciousness about disaster prevention from “foods” which are familiar to them. Therefore, we have concluded it is available to use disaster prevention awareness dishes as an effort of those activities.

    Usuki City, Oita Prefecture, where huge tsunami damage is expected due to the Nankai Trough Huge Earthquake, has risks such as sediment disasters, floods, typhoons, as well as earthquake tsunami. It is necessary to further improve the disaster prevention awareness toward large-scale disasters that may occur in the future. The contents of questionnaire survey to residence associateion is the Disaster Risk Assessment, Preparation for Disaster, Disaster prevention activities and its cooperation and Requests to schools and administration (Free description). Regarding Disaster Risk, there are many people who high evaluate comprehensively. The extent of efforts concerning Disaster Prevention differed depending on residence associations and question items. In free description, despite consciousness of disaster prevention, it was clear that residence association and the school could not collaborate together. By considering this result together, It will be possible to practice appropriate measures according to the area.

    Most of fragility functions for wooden house have only attributes of structure and built year, though it has been recognized that roof weight is correlated to damage. In this study we tried to improve the prediction accuracy by considering the roofing type and stories. The fragility function was proposed on the basis of the distribution of seismic capacity score, building data and damage data around the observation stations as well as observed records of past earthquakes. As a result, the predicted values of this study can explain the actual damage more accurately than those of Central Disaster Management Council.

    We investigated disaster risk perception and disaster preparedness at early childhood education and care (ECEC) facilities in Japan. Facility directors of 4,200 ECEC facilities were asked to participate in this study after being selected by random sampling (about 11% of all Japanese ECEC facilities). A questionnaire survey was administered from November 25, 2017 through February 15, 2018. Results revealed the following: (1) ECEC facilities assume disaster risks mainly from earthquakes, typhoons, and fires; (2) few facilities provide contents of disaster preparedness of facilities to guardians; and (3) most disaster prevention manuals currently used at ECEC facilities include matters related to physical and mental condition and psychological support after a disaster.

    In the response phase of the disaster management cycle, colleting information of disaster damage to establish shared situation awareness among organisations and make actionable decesions often take time. We have developed a new methodology to immediately make the information of estimated damaged buildings by photointerpreting aerial photos or satellite images and share it as web maps on the cloud based GIS platform and in downloadable csv format. The methodology has been verified in the casestudy of the Northern Kyushu heavy rain disaster in 2017 and applied to the West Japan heavy rain disaster in 2018.

    A council is gradually adopted for consensus building in participants of consultations in many policy issues. Disaster Prevention is no exception. This paper alies the concept of “The Consultation Unit” which is defined in the study of lateral coordination in Japanese bureaucracy to disaster prevention. Then I consider the attribute of a council for disaster prevention. I clarified that installation of the council for disaster prevention act as restriction on competence for regulation of local government. As a result, the council for disaster prevention strengthen the effect of disaster prevention information without spending much cost directly caused by lockout, evacuate and harmful rumor.
