Accurately evaluating pedestrian congestion is crucial for evidence-based improvements in various walking environments. Tracking pedestrian movements in real-world settings often leads to incomplete data collection. Despite this challenge, pedestrian congestion with missing data has not been extensively addressed in existing research. This study examined the impact of missing data on density, speed, and congestion number in the course of evaluating pedestrian congestion. While density is the most commonly used index, speed and congestion number proved more robust.

In tourist facilities, managing ticket sales can reduce congestion imbalances. This study reports on the results of a pilot experiment conducted at Kaiyukan in Osaka, one of the largest aquariums in Japan. The experiment utilized pre-sale ticket data for controlling admission time intervals, smoothing the number of admissions through dynamic pricing, and predicting visitor numbers. The study reviewed the effectiveness of each of these approaches to alleviate congestion inside Kaiyukan. We then report on a method to predict the number of visitors from the pre-sale conditions of Kaiyukan admission tickets. It was found that setting entry times to 15-minute intervals was most operationally advantageous for the Kaiyukan. Moreover, the behavioral effects induced by variable pricing were more effective when prices were changed based on time slots rather than on a daily basis. Compared to the Holt–Winters’ method, we were able to maintain stable prediction accuracy even during consecutive holidays and long school vacation seasons.

When designing crowd control through simulations, the appropriate crowd-control medium (objects used to convey control information, e.g., signages or security guards) and information should be selected, considering the crowd’s compliance with control instructions. However, there is still scope for further research on the influence of control medium and information on compliance behavior. Therefore, in this study, we measured the effectiveness of medium and information in guiding participants’ route choices by conducting a crowd experiment using virtual reality. The experimental findings confirmed that in terms of control medium, the guidance proffered by security guards was more effective than signage, with the odds of compliance rate approximately 1.54 times greater. Regarding control information, Guide control (direct guidance instruction) was more effective and received approximately 1.22 times greater odds of compliance rate than Advise control (indirect guidance through information presentation). Crowd-control designers can use the results obtained in this study to evaluate the effectiveness of control measures in crowd simulations.

Tsunamis resulting from earthquakes can cause extensive damage, including infrastructure destruction, injuries, and fatalities. To address these risks, numerous tsunami evacuation simulations have been conducted to assess evacuation strategies and identify issues, particularly in Japan, where the Nankai Trough earthquake is anticipated, affecting underground malls in urban areas. Our previous research primarily focused on evacuating from underground to the surface, neglecting surface evacuation. Therefore, this study extended the previous study to include horizontal evacuation following the exit from the underground mall to ground level. It also considered the impact of pedestrian road crossings as interactions with vehicular traffic within the simulation to enhance realism and verify the evacuation risk. The study also explores scenarios where evacuation guide stairs are unavailable, comparing the effectiveness of alternative staircases in the evacuation plan. Results indicate that while using alternative staircases temporarily increases the number of evacuees reaching the surface, road crossings on evacuation routes become significant bottlenecks, leading to surface congestion and delayed evacuations. This raises doubts about the effectiveness of alternative staircases and highlights the need to consider alternative evacuation routes as a secondary plan. Additionally, the study reveals that reduced pedestrian flow at road crossings can significantly impact on evacuation times. Ultimately, this study demonstrated that achieving a short evacuation time from underground malls to the ground level might not always yield the best evacuation plan. It underscored the importance of considering aboveground factors in evacuation planning to ensure safety in the event of a tsunami caused by an earthquake.

The national earthquake and national volcanic eruption prediction programs of Japan started in 1965 and 1974, respectively, based on the recommendation of the Geodesy Council. As a result, observations of seismic and volcanic activity have been enhanced and our understanding of the mechanisms of earthquakes and volcanic eruptions has made significant advances. However, these research results did not fully contribute to mitigating the damage caused by the 1995 Kobe earthquake or the 2011 Tohoku earthquake. In order to make further contributions to disaster mitigation, we recognize the importance of research to apply the scientific understanding of earthquakes and volcanic eruptions in collaboration with researchers in related research fields. The Earthquake and Volcano Hazards Observation and Research Program (2014–2018) was thus started on the basis of a recommendation of the Council for Science and Technology. In this Program, research in the area of forecasting the hazards of earthquakes and volcanic eruptions has become one of the main pillars of research. Disaster information and knowledge of the disaster process, which involve the interaction of hazards and natural and social vulnerability, have been investigated in cooperation with earth scientists, engineers, and social scientists. On the basis of our results, research on literacy for disaster resilience was selected as one of the main pillars of research in the Second Observation and Research Program of Earthquake and Volcano Hazards (2019–2023), because a better understanding of and immediate information about disasters are important for disaster mitigation. This special issue, which aims to disseminate the results of almost five years of research activities on literacy for disaster resilience in that Program, includes 15 papers and survey reports from multidisciplinary fields of study. The collection begins with Kimura and Ikeda’s important paper discussing the conceptual structure of the knowledge and abilities necessary to build disaster resilience capacities by analyzing school and community-based efforts, followed by a variety of empirical studies that are loosely categorized into two groups. The first group of papers concerns the understanding of disaster processes and mechanisms themselves as a factor inducing disaster prevention and mitigation. First, Ebina and Sugawara, and Sugimori attempt to learn lessons from the pre-modern earthquake disasters based on past picture maps and scrolled records, respectively, followed by Ohkura’s interesting paper that points to problems in the Aso Volcano disaster mitigation system by analyzing the 2021 phreatic eruption process. Next, utilizing information and communication technology to support effective evacuation, Inoguchi, and Shiozaki and Hashimoto develop a disaster management toolkit and the tsunami drill program, respectively. The following two papers of Takubo et al. discuss behavioral mechanisms in a disaster period based on their

This study aims to consider the effects and problems of a tsunami evacuation drill support system that visualizes dynamic tsunami data and evacuees’ locations. The system was developed and operated during a tsunami evacuation drill experiment. The location information application transmits evacuees’ locations in real time using the GPS and network functions of a multi-function terminal. The web application visualizes tsunami data and evacuees’ locations with animation on a web map using WebGIS. By operating the system in the tsunami evacuation experiment, the study could immediately evaluate the evacuation drills through real-time visualization of the evacuees’ actions. Feedback, including the results and evaluations of the evacuation drills, was provided to the participants. Before receiving feedback, 50% of the participants positively evaluated the drill results. However, 42.1% of the participants changed their evaluation to negative after receiving feedback. Additionally, by emphasizing the speed of action during evacuation as one of the important factors for quick evacuation, the system helped to alter participants’ disaster prevention awareness.

The Nankai Trough Earthquake, which is estimated to have a 70%–80% probability of occurring within the next 30 years, necessitates considering various scenarios due to the extensive seismic source region and call for advancing disaster preparedness measures. Assessing direct damage caused by earthquakes is considered particularly challenging compared to assessing human and physical damage due to its intricate composition. However, the existing research in model analysis aimed at real-time estimation has yielded results, namely, the ability to promptly calculate direct damage from earthquakes using seismic motion and stock quantities as inputs. This study aimed to leverage the research outcomes of real-time estimation to approximate the direct damage costs that would be caused by the Nankai Trough Earthquake. Three hazard assessment cases were selected, based on damage estimations to be attempted. The results indicated that a damage estimation approach based on a common foundation dataset and model analysis considering different occurrence scenarios is more suitable for evaluating results and assessing the importance of mitigation measures than conventional scenario-based damage estimations.

The great earthquake in 1855 caused extensive damage to Edo, where the shogunate was located and more than one million people lived. The picture scroll on the subject of this earthquake, Edo Ohjishin no Zu, has been conventionally understood as depicting the general situation in Edo before and after the earthquake. However, an examination of related historical documents reveals that the scroll depicts the specific situation in the area between the Saiwaibashi-mon Gate and the Shiba Residence of the Satsuma Domain up to three months after the earthquake. The depiction of the damage and people’s behavior corresponds well with the descriptions in the historical documents. Edo Ohjishin no Zu shows the damage caused by the earthquake and fire, and the restoration process based on the facts, indicating that restoration progressed to some extent in the town areas during the three months after the earthquake. The premise that made this possible was the experience in dealing with fires that had accumulated in Edo, where fires were common. Although it was the first time for the machi-kaisho offices to provide relief in the wake of an earthquake, they quickly responded to the complex disaster involving fire by drawing on their past experience. Edo Ohjishin no Zu is a historical material that describes the sequence of events from the occurrence of the earthquake to the restoration process and can be used as a reference for disaster response even today.
