Since Japan has 111 active volcanoes, we living there need to be prepared for the volcanic disasters that we will likely encounter in our lifetime. The Integrated Program for Next Generation Volcano Research and Human Resource Development (INeVRH), a research project of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), started in 2016 and is now in its 7th year. It is approaching its final stage will be ready to make proposals that will improve our knowledge from both scientific and practical points of view. In theme A, the Japan Volcanic Data Network (JVDN) system started its function as a volcanic research platform, providing the observation and analysis data of many universities, governmental agencies, and institutes. The JVDN system promotes collaborative, multidisciplinary study. In theme B, many strategic observation techniques now deployed have revealed the characteristics of volcanoes in detail. For example, a dense seismic and magnetic survey has clarified the fine structure of the hydrothermal system beneath volcanoes, providing information that can be used to evaluate their phreatic eruption potential. In addition, brand-new volcanic gas observation techniques using drones now obtain in-situ information effectively. Theme C has obtained geologic and petrologic findings at many volcanoes and has come to the stage in which systematic compilation of this database would be useful to comparative studies of many volcanoes. These findings are also used in numerical simulations that combine geologic, petrologic, and geophysical formulations to produce more comprehensive models used to interpret volcanic activity. Theme D focuses on the development of practical technologies for volcanic disaster mitigation, mainly related to volcanic ash. A scheme for the quick detection and evaluation of volcanic ash is proposed through observation and numerical simulation, and an experiment is performed to reveal the thickness threshold of volcanic ash deposits on air-conditioners. This special issue reports on some up-to-date topics that could become the basis of dynamic and effective links between themes A, B, C, and D, which may serve as a base and direction for discussions that summarize and conclude this 10-year project.

Migration is dynamic and varies greatly across the globe due to myriad factors, including demography, economy, geography, and environment. As people move, a number of challenges exist that can leave human rights and human dignity as an afterthought to the migration process. This special issue provides a legal and policy framework for supporting “migration with dignity,” providing examples of how to apply this framework across a number of contexts, including climate change, the migration cycle, and pandemics.

COVID-19 has drastically changed mobility and migration in key spheres, such as transportation, travel, construction, and hospitality. Our research for this special issue was conducted between 2020 and 2021; therefore, we had the opportunity to witness a once-in-a-century global pandemic with direct impacts on migration inflows and outflows. Consequently, we have included pandemics as a key theme for consideration in this issue, believing that the research agenda should be informed by the assessment of impacts in both the atoll countries and in the United States – the most common “destination” of Pacific Islanders. This additional research revealed the vulnerabilities of migrants in the destination countries and in their home countries, vulnerabilities that would not otherwise have been apparent.

Our research was also directly impacted by the pandemic. We intended to conduct field research in countries such as the Republic of the Marshall Islands (RMI), the Federated States of Micronesia (FSM), and the Republic of Maldives, with the RMI and FSM serving as countries of “origin” for migration to the United States. In the Maldives, there is a large domestic migration from the atolls to the newly constructed man-made islands. We experienced research and travel limitations due to COVID-19, where many countries have adopted strict isolation policies to prevent the spread of disease. Therefore, we had to conduct our surveys remotely using the Internet or by asking collaborators living in the area to conduct surveys on our behalf.

Our special issue also touches on the issue of the intergenerationality of immigrants in terms of how migrants adapt or assimilate into the receiving society, and how the mass media plays a role in the perceptions of migrants and the perceived problems associated with immigration by host countries. Many opportunities remain for further exploration and research, including how migration has changed in the post-pandemic world. We intend to pursue these opportunities in 2022 and beyond.

Japan is a country that experiences a considerable number of natural disasters. It sees frequent seismic and volcanic activity because it is located on the boundaries of multiple plates. In addition, the temperate monsoon climate brings heavy rains and therefore floods and landslides. Since ancient times, the Japanese have repeatedly recovered from various natural disasters. That history has much to teach those living alive now.

In Japan, observation systems for earthquakes and volcanic eruptions have been set up, and research based on the records of these instruments is actively being done. However, some earthquakes and eruptions repeat at intervals of hundreds of years, making the investigation of historical and archaeological materials essential if the true circumstances of such natural events and damage they caused are to be learned. A part of the historical disaster research currently being conducted in Japan is presented in this mini special issue.

This mini special issue contains four papers. Ebara’s paper, taking up the ways in which artificial development has transformed the topography in the last 500 years, considers the relationship between the original topography and the damage caused by typhoons. Kaneko’s contribution considers the damage sustained by one village that was hit by the tsunami that resulted from the great earthquake in the early 18th century. Kaneko surveys archaeological sites and tombstones that reveal that many of the victims were women and children. Sugimori et al. elucidate the exact time of the great earthquake in the 19th century by using historical materials written in Japanese, English, and Russian. Along with the importance of comparing and contrasting various literatures, the work teaches us that disasters have no borders. Murata proposes a method of utilizing archaeological excavations in earthquake research. It also presents a case in which the condition of the ground, which cannot be understood by surface observation alone, is estimated from traces of a disaster.

From these papers, readers can learn the potential of historical and archaeological materials in disaster research.

This special issue focuses on “Build Back Better,” which is the key concept of the Sendai Framework for Disaster Risk Reduction (2015–2030). The Sendai Framework for Disaster Risk Reduction provides United Nations member states and economies concrete actions to protect their economic development achievements from disaster risk. However, how “Build Back Better” can be measured and linked to disaster risk reduction remain unclear.

Three papers here analyze the results of the “Life Recovery Survey Five Years After the 2011 Great East Japan Earthquake,” which was conducted in June of 2016. The first Life Recovery Survey was conducted four years after the 1995 Great Hanshin-Awaji Earthquake to document the extent to which the disaster victims had been able to rebuild their lives. Subsequently, the survey was conducted every two years until ten years after the earthquake. The survey was also conducted in the areas affected by the 2004 Niigata Chuetsu Earthquake and the 2007 Niigata Chuetsu-Oki Earthquake. Five years after the Great East Japan Earthquake of 2011, the present authors conducted a survey to document the actual situation of the disaster victims in Iwate, Miyagi, and Fukushima prefectures, which were the hardest hit by the disaster.

In addition, we analyzed the history of Nankai Trough earthquakes with the goal of preparing for the next Nankai Trough earthquake, which is predicted to occur in the near future. These results make it possible to identify issues and make recommendations on the kinds of systems that should be implemented.

It is our hope that this special issue will provide basic data to elucidate these issues.

The main goal of the conceptual framework of this mini special issue, which is based on the International Symposium on Human Survivability 2016 (ISHS2016), is to provide a fresh look at the global challenges facing humanity in the areas of energy, water, food, population, disease, etc. The ISHS2016 focused on enhancing resilience to extreme or large-scale disasters that may threaten the well-being of present and future generations. By considering past, present, and future dimensions, we aimed to develop a holistic approach that integrated various research fields.

The symposium brought together scholars from not only the natural and social sciences but also the humanities. The idea behind this was that we need to go beyond the “silo-based” approach, where handling disasters is something left to experts with specialized knowledge. The integration of the knowledge of scholars from different academic fields and backgrounds could provide novel solutions to the problem of how to enhance our resilience to future disasters.

This mini special issue aims to identify key issues in prioritizing several different types of disasters in terms of their time frames and impact frames, with the knowledge that the disasters are of completely different types and that the capacity of each institution and the consciousness of society in terms of each issue are all unequal. From those, we may identify the main characteristics of “low probability and high impact disasters,” as well as the different approaches that are needed. Disasters vary from infectious diseases to space weather, tsunamis, and earthquakes.

COVID-19, which originated in Wuhan, China, 2 years ago, became a pandemic, that continues to this day.

The Journal of Disaster Research (JDR) edited a special issue, “Special Issue on COVID-19 and Historical Pandemics” at the end of 2020 and an electronic version of the issue was published in January 2021 (JDR Vol.16, No.1, pp. 1-117).

Even though one year has passed, life has not yet returned to normal due to the continued spread of COVID-19. Although the percentage of the general public that has been vaccinated continues to increase and various drugs and treatments have been developed, the number of COVID-19 cases also continues to increase. A huge number of COVID-19 cases have been reported, especially in Europe and the Americas.

Accordingly, we planned to publish Special Issue Part 2 and called for papers.

This Special Issue Part 2 includes 18 manuscripts, which deal with general epidemiology, effects on socioeconomic or educational areas, and clinical medicine, including vaccines and medical treatments.

The virus spike protein plays an important role in its intrusion into human cells and the onset of COVID-19 infection. Although SARS-CoV-2 (the pathogenic virus of COVID-19) originated in Wuhan, China, various variant strains with mutation in gene coding in the spike protein have appeared in multiple countries. The WHO classifies these variants into the categories of VOC (variant of concern), VOI (variant of interest), or VUM (variant under monitoring).

The definitions of VOC and VOI are as follows. VOC: “A SARS-CoV-2 variant that meets the definition of a VOI and, through a comparative assessment, has been demonstrated to be associated with one or more changes in the degree of global public health significance.” VOI: “Increase in transmissibility or detrimental change in COVID-19 epidemiology, increase in virulence or change in clinical disease presentation, or decrease in effectiveness of public health and social measures or available diagnostics, vaccines and therapeutics.”

The WHO uses Greek letters designating the variants. Accordingly as they have appeared, variants have been designated as alpha (α: the UK variant), beta (β: the South Africa variant), and delta (δ: the Indian variant).

After the deadline for the manuscript of this special issue, a new variant, omicron (o) originated in South Africa and Botswana, and it immediately began spreading worldwide. Unfortunately, it was impossible to include the manuscript on the omicron variant in this Special Issue Part 2, as the deadline had already passed.

As COVID-19 continues to spread, the JDR will plan to edit Part 3 of this COVID-19 special issue.

We announce that the Seventh JDR Award was won by Prof. Suminao Murakami, Laboratory of Urban Safety Planning. We congratulate the winner and sincerely wish for future success.

On behalf of the Editorial Board of the Journal of Disaster Research (JDR), it is my great honor and pleasure to present the 2021 JDR Award to Prof. and Dr. Suminao Murakami, or “Murakami Sensei.” Murakami Sensei has served as the founding Editor-in-Chief of the JDR for the past 16 years, since 2006. The JDR has now published more than 100 issues, becoming recognized as the leading Japan-based, international online peer-review journal on disaster risk reduction for all hazards except war, and Murakami Sensei has always been its greatest contributor. The Editorial Board reluctantly respected Murakami Sensei’s decision to resign from the position of Editor-in-Chief, but it has unanimously agreed to rename the JDR Award to the MURAKAMI Suminao Award for Disaster Research from 2022 on. The Journal of Disaster Research will continue its best efforts “to reduce the horrors of disaster through information,” as Murakami Sensei and Takiguchi Sensei wrote in the Message from the Editors-in-Chief in the first issue of the JDR.

In the year 2021, the Journal of Disaster Research (JDR) had two memorable events: Professor MURAKAMI Suminao, one of the founders of the Journal, resigned as the editor-in-chief, and in February the JDR marked its hundredth issue, counting from Vol.1 No.1. These events gave us, the next generation of the editorial board members, the resolve to reinvent the JDR for its leap forward into the next stage.

We have accomplished the following two projects this year.

Establishment of MURAKAMI Suminao Award for Disaster Research and the JDR annual awards

To acknowledge Professor MURAKAMI’s significant contributions to the JDR and disaster research in general, we rename the JDR Award to the MURAKAMI Suminao Award for Disaster Research. While we present this award to the person who has made the most significant contribution to disaster research as a whole, we hereby establish three more specific JDR annual awards: the JDR Award for the Most Cited Paper, the JDR Award for the Most Downloaded Article, and the JDR Award for the Most Contributory Reviewer.

Applying the Creative Commons license

The JDR introduced the Creative Commons license in August 2021, thereby becoming a fully open-access journal conforming to the international standard. This project makes all articles in the JDR easier to reuse and cite in academic activities.

Now the JDR is widely known not only in Japan but also all across Asia, and its readership is spreading through North America and Europe. We will continue to strive for the further development of the JDR as an international journal dedicated to comprehensive disaster research.

Numerical simulation and modeling became an essential technology in tsunami research and disaster management. Various numerical models were proposed and utilized for the development of tsunami risk assessment, inundation maps, and evacuation plans. The model verification and validation standards would be crucial to ensure sufficient reliability of tsunami risk assessment, inundation maps, as well as a consistency among various efforts. Common approach to ensure sufficient accuracy and reliability of numerical modeling is developing benchmark problems of hydraulic experiments and to use them for numerical model’s verification and validation.

To satisfy this requirement, “Tsunami Modeling Hackathon” was held in September 2020 to organize new benchmark problems in numerical modeling of tsunamis and to improve their reliability and accuracy. Hackathon is an intensive-gathering event of computer programmers and others involved in software development to create outcomes by the end of the event. This event was organized by Prof. Tomoyuki Takahashi of Kansai University and his colleagues, who led the tsunami research subcommittee in Japan Society of Civil Engineers (JSCE).

Tsunami modeling hackathon, in which about 23 teams and 162 researchers joined, included experiment and modeling teams in seven benchmark problems: urban tsunami inundation, landslide tsunami, tsunami loading on seawalls and coastal structures, sediment transport, drift of floating objects. The modeling groups performed the blind tests to cross-validate and interpret the results of their simulations in seven benchmark problems given by the experiment groups and discussed the improvement.

This special issue reports the outcomes of the tsunami modeling hackathon, and includes six papers (five in this issue, one in the regular issue). We hope this issue will provide useful insights for tsunami modelers and contribute to establishing a standardized way to ensure that various tsunami numerical models would be validated through the benchmark problems.

We are very pleased to publish this Mini Special Issue, dedicated to NIED Frontier Research on Science and Technology for Disaster Risk Reduction and Resilience 2021. Three papers and one survey report are included.

Miura et al. indicate the scope of disaster prevention covered by the new courses of study in the field of disaster prevention. By visualizing the contents of classification and analysis, they propose how to handle the scope of disaster prevention in disaster prevention learning in consideration of the comprehensiveness to solve the problems. In the second paper, a case study on flood damage in Hitoyoshi, Kumamoto Prefecture, Mizui and Fujiwara analyze a method of immediately determining the amount of waste disposal work and the number of residents and disaster volunteers required in the event of a disaster. Fujiwara et al. study the feasibility of estimating damage to large-spanned building structures by conducting shake table tests on a small gymnasium model with simulated damage and measuring the natural frequencies and mode shapes. Onoue et al., in a work published as a survey report, present a method for analyzing slope displacement by using the distance image data of a depth camera. They indicate the possibility of detecting minute changes that can precede slope failure.

We hope this issue provides information useful to all readers who study natural disasters.

A holistic and comprehensive perspective on society is essential to disaster research. However, at one time, the world did not have any scholarly journals that dealt with disasters from a holistic point of view. This situation gave rise to the Journal of Disaster Research (JDR), the first issue of which was published in August 2006. In principle, six issues are published annually, with special or extra issues also published in some years.

The Great East Japan Earthquake struck in March 2011, five years after the first issue of the JDR. Following this incident, we decided to publish a special issue whenever there was a major disaster. All accepted papers and articles were to be published free of charge, in electronic format. So far, eight special issues have been published.

Since this year 2021 marks the tenth anniversary of that disaster, we at the JDR have decided to publish a special issue of notes on the Great East Japan Earthquake Disaster. The selected theme is “Thoughts About the Great Disaster Now That Ten Years Have Passed.” As an academic journal dealing comprehensively with disasters and disaster risk reduction, we asked people working in all disaster-related fields to submit, from their unique perspectives, their views or proposals in any area or subject regarding what changes have taken place, what has remained the same, or what is needed in the future.

We have the twelve notes presented here in this Special Issue on the Great East Japan Earthquake Disaster: Part VI. We hope that these notes provide seeds for further progress in the field of disaster research.

Lastly, the editors would like to thank all contributors who submitted their manuscripts and the reviewers who provided valuable feedback with their constructive comments.

This special issue summarizes some of the findings of the first half of our international joint research between Japan, Thailand, and Vietnam. This collaborative research is based on the framework of the e-ASIA Joint Research Program (e-ASIA JRP) and lasts for three years. Rainfall-induced landslides are a common disaster in many Asian countries. Our goal is to develop a practical method for landslide susceptibility mapping so that there are fewer landslide disasters in the future.

The e-ASIA JRP is an international joint initiative of public funding organizations in the East Asia Summit member countries. Based on the co-funding mechanism, support for the research teams is received from the funding organizations in their respective countries. Since 2019, the Japanese, Thai, and Vietnamese teams have been supported by the Japan Science and Technology Agency (JST), the National Science and Technology Development Agency of Thailand (NSTDA), and the Ministry of Science and Technology of Vietnam (MOST), respectively.

In the first half of our project, we completed the basic steps for developing the system. In this special issue, we are proud to present some of our achievements, including studies on slope failure analysis, landslide prevention works, meteorological observations, landslide monitoring, statistical or wide-area risk evaluations, mathematical models, and flash flood control. In addition to the above, we also present other valuable research achievements that related members have provided to help ensure the achievement of our goals. In total, 20 papers are published here. We believe that our comprehensive research activities will dramatically increase future landslide disaster mitigation, especially in monsoon Asia, and will strongly augment the roadmap for achieving the global Sustainable Development Goals (SDGs) as a common desire of humanity.

Natural hazards continue to be an increasing challenge to societies around the world, with many societies being impacted by multiple types of hazard events. To reduce the impact of these hazards, we must not only quantify the hazard and risk associated with multi-hazard events but also understand the uncertainty associated with these events. Resilience can only be improved by considering all these factors. Multi-hazard and risk-modeling approaches are receiving increasing attention globally; however, the challenges of assessing uncertainty in both single- and multi-hazard risks are considerable. Without a clear understanding of the risks and their uncertainties, measures to mitigate these risks and to increase resilience face difficult decisions. In the present Special Issue, we have five papers and one report on the Tokyo Metropolitan Resilience Project: Interdisciplinary and Industry-Academia Collaboration Research for Enhancing Social Resilience to Natural Disasters in the Tokyo Metropolitan Area –DEKATSU Activity–, Multi-Data Integration System to Capture Detailed Strong Ground Motion in the Tokyo Metropolitan Area, Development of the Training Tool “KUG” for Temporary Lodging Facilities and Companies for Stranded Commuters, Development of Matching Modeling for Human Resource Allocation of Shelter Management by the Set Theory, Time-Cost Estimation for Early Disaster Damage Assessment Methods, Depending on Affected Area, and A Report of the Questionnaire Survey on Awareness of COVID-19 and Shelters.

As rainfalls exceeding the designed level have increased, so has damage associated with pluvial flooding. Typhoon Hagibis, which swept Japan in 2019, left 140 municipalities in 15 prefectures scarred from flooding. The sewage networks damaged by the typhoon affected civic life by paralyzing urban functions, raising concerns in urban flood risk and management. Increases in heavy rainfall events associated with global climate change are expected to increase damage from pluvial flooding, thereby necessitating reviews of current urban flood risk management for the purpose of making further improvements against future threats. As we enter an era of frequent urban flooding, it is vitally important that we prepare for urban flood risk management by sharing scientific and technological knowledge among academics, private companies, and administrators.

In this context, the current issue is a compilation of contemporary research studies in academia, technological advances in private companies, and practical applications in public administrations in Japan. The works include: the application of urban flood modeling in safe evacuation strategies, the assessment of economic loss, and the impact of climate change; state of the art technologies for urban flood management with the Internet of Things (IoT) and Internet Communication Technology (ICT), Unmanned Aerial Vehicles (UAV), and the next generation of weather radars; and best practices for flood countermeasures, based on knowledge and experience from historical flooding and applied in prefectural governments and local municipalities.

We are grateful to all the authors and reviewers who contributed to this special issue, and we hope that it may internationally enhance knowledge-exchange in preparation for growing urban flood risks.

This special issue of the Journal of Disaster Research focuses on disaster storytelling, an emerging concept in disaster risk reduction. Despite its popularity and importance, its individual practices and activities, as they tend to be spontaneous and local, have received only limited attention from academia and have not been given special attention by the disaster research community.

The papers included in this volume contain multi-dimensional discussions on disaster storytelling, including ones that focus on concepts and theory, the functions of disaster museums, tourism, local communities, UNESCO geoparks, disaster ruins and heritage, art and culture, and disaster education. The readers can understand the variety of disaster storytelling activities that exist around the world and their potential contribution to building resilience in society. We believe this issue is the first academic publication to focus specifically on disaster storytelling, and we hope that this volume contributes to creating scientific value, attracts additional attention, and develops further discussions about the role of disaster storytelling within the disaster research community. We also believe that such discussions will help various individuals and entities reidentify the importance and significance of their activities of disaster storytelling as well as contribute to continuing or strengthening such activities around the world.

All of the contributors to this issue participated in the International Forum on Telling Live Lessons from Disasters (TeLL-Net Forum), held January 24–26, 2020 in Kobe, Japan. The articles included in this issue include ones that were inspired by discussions during and after the forum. Readers interested in this forum can obtain the official report from the TeLL-Net website: https://tell-net.jp/forum2020/pdf/00_Tell_Net2020_Report_print.pdf.

We, the editorial board of this special issue, would like to express our deep appreciation to the Hyogo Earthquake Memorial 21st Century Research Institute for the research grant on disaster storytelling. We also would like to express our gratitude to the Kobe Machizukuri Rokko Island Fund Charitable Trust (Tokyo, Japan) and AIG Institute (Osaka, Japan) for financial contributions that supported the publication of the issue.

COVID-2019 was first identified in Wuhan, China, at the end of 2019, and from there it spread worldwide. Due to this worldwide distribution of COVID-19 cases, the WHO declared a COVID-19 pandemic. The pathogen of COVID-19, a novel corona virus, resembles SARS-CoV, the pathogen of SARS (severe acute respiratory syndrome, a pandemic in 2003), so the International Committee on Taxonomy Virology named it SARS-CoV-2. However, COVID-19 is a different disease from SARS, and should be controlled to the extent possible with the effective vaccines and therapeutic medicines.

Although one year has passed since the first appearance of the disease, the number of COVID-19 cases continues to increase, and the pandemic is now in its third large wave. It is thought that it will be difficult to eradicate the disease completely, because SARS-CoV-2 is possible to invade and live in various host animals in addition to humans.

During this pandemic, the JDR has put together the special issue “COVID-19 and Historical Pandemics.” Because there have been many pandemics that have transformed society in various ways, the special issue includes historical pandemics in addition to COVID-19. The manuscripts in this issue include various subjects related to COVID-19, including methods of analyzing the pandemic, suggestions for countermeasures against it, methods of prevention and epidemiological reviews, among others.

The WHO has released a large volume of pandemic information on an ongoing basis, including its “COVID-19 Weekly Epidemiological Update.” In the weekly edition of December 27, it reported the cumulative number of cases and percentages of the global total from around the world: the Americas 34,403,371 (43%), Europe 25,271 (31%), Africa 1,831,227 (2%), and the Western Pacific 1.059,751 (1%). It is notable that 74% of cumulative global total number of cases have been reported in the Americas and Europe, where most developed countries are included, whereas the numbers in Africa, which includes many developing countries, and the Western Pacific region, which includes Thailand, the Philippines, Vietnam, and Malaysia in addition to Japan and China, are 2% and 1%, respectively. This indicates that the COVID-19 pandemic is a different from previous epidemics caused by other infectious diseases.

As the pandemic spreads, the JDR plans to edit Part 2 of this COVID-19 special issue.

The World Bosai Forum/International Disaster Risk Conference@Sendai 2019 (WBF2019) held in November 2019 in Sendai City, Japan, was successful in bringing together actors from multiple sectors to advance the goals of disaster risk reduction (DRR). We would like to take this opportunity to express our heartfelt gratitude to all those who participated in the sessions, exhibitions, poster sessions, and mini-presentations, as well as to the many local people who came to the event.

According to the World Bosai Forum [1], 871 participants from 38 countries attended the WBF2019 which included 50 oral sessions, 3 keynote speeches, 47 poster sessions, 33 mini-presentations, and 14 exhibition booths, which contributed to deepening the discussion and promotion of the “Sendai Framework for Disaster Risk Reduction, 2015–2030” (SFDRR) and in particular progress towards the achievement of Global Target E, to substantially increase the number of countries with national and local disaster risk reduction strategies by 2020. Including lessons learned from the Great East Japan Earthquake and Tsunami, local knowledge and solutions towards advancing BOSAI were actively shared and discussed among the participants who joined this global forum, from various organizations and sectors. In particular, there were many sessions in which young people and private companies played a key role.

The guest editors are pleased to publish this special issue of the Journal of Disaster Research, which is comprised of 13 articles sharing the research advancements presented at the WBF2019. We hope that this special issue on the WBF2019 will contribute to the literature on disaster science and further advances in disaster risk reduction.

The Global Centre for Disaster Statistics (GCDS) at the International Research Institute of Disaster Science (IRIDeS) at Tohoku University was established in April 2015 to support the monitoring of the global targets of the Sendai Framework for Disaster Risk Reduction 2015–2030 (SFDRR). The GCDS, in partnership with the United Nations Development Programme (UNDP), is to provide support for National Disaster Management Offices (NDMOs) to build capacity in developing national disaster loss and damage statistics, an essential tool used in monitoring and policy making for the reduction of disaster risk. Since its establishment, the GCDS has been contributing to the implementation of the SFDRR.

In 2019, the GCDS participated in the Sendai Framework Voluntary Commitments (SFVCs), launched by the United Nations Office for Disaster Risk Reduction (UNDRR). Although the information regarding the activities of the GCDS is described in detail in the first Synthesis and Analysis Report of the SFVC [1], one of the activities committed to in its SFVC is to publish special issues of the Journal of Disaster Research as a contribution to the development of disaster statistics. The guest editors are pleased to publish the third special issue, which contains valuable academic articles closely related to the activities of the GCDS.

We hope that this special issue on the Development of Disaster Statistics makes a significant contribution to the literature on disaster statistics and accelerates its development.

We are very pleased to publish the Special Issue on NIED Frontier Research on Science and Technology for Disaster Risk Reduction and Resilience 2020. There are nine papers in this issue.

The first two papers concern hazard and risk information systems: Sano et al. constructed a real-time risk information map for flood and landslide disasters, and Hirashima et al. created an alert system for snow removal from rooftops. These systems are already in use on the NIED website. The next three papers are case studies of recent storm disasters in Japan and the United States: Cui et al. analyzed the time variation in the distribution of damage reports in the headquarters for heavy-rainfall disaster control in Fukuoka, Shakti et al. studied flood disasters caused by Typhoon Hagibis (2019), and Iizuka and Sakai conducted a meteorological analysis of Hurricane Harvey (2017). Regarding volcanic disasters, Tanada and Nakamura reported the results of an electromagnetic survey of Mt. Nasudake.

This special issue also includes three papers on large-scale model experimentation: Danjo and Ishizawa studied the rainfall infiltration process using NIED’s Large-Scale Rainfall Simulator, Kawamata and Nakazawa conducted experiments concerning liquefaction, and Nakazawa et al. reported the results of experiments on seismic retrofits for road embankments. The experiments used E-Defense, the world’s largest three-dimensional shaking table.

We hope this issue will provide useful information for all readers studying natural disasters.

This special issue summarizes the main results of the first two years of the Science and Technology Research Partnership for Sustainable Development (SATREPS) project, which is supported by the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). SATREPS has provided excellent opportunities for our joint research team from Thailand and Japan to work in close coordination on challenging multidisciplinary issues.

The Area-BCM for the Enhancement of Resilience of Industrial Complexes in Thailand project was started in 2018. Its scope includes the impacts of urban flooding disasters in Bangkok and its surrounding areas where socio-economic functionalities have been concentrated, as well as chain repercussions of disaster impacts, spread through global supply chains, in important production and logistics facilities in Thailand. Our high-level project targets are based on the Sendai Framework for Disaster Risk Reduction (SFDRR) 2015–2030 as well as Sustainable Development Goals (SDGs), especially #11 (Sustainable Cities and Communities), #8 (Decent Work and Economic Growth), and #13 (Climate Action).

This issue contains interim research results from our project mainly led by members from Thailand with regional aspects of our project site. However, we plan to release another special issue by the end of our project that will include more generalized concepts and frameworks that can be applicable to other regions or countries, including Japan.

As we take a multidisciplinary approach that includes science and technology, life and well-being science, and social science, our main objective in featuring this special issue is to make our interim research results known to other researchers and practitioners in related fields. We do this in order to get opinions and suggestions from different perspectives so that these may be reflected in the directions our research takes during the remainder of our project term.

Finally, I am truly grateful for the authors’ insightful contributions and the referees’ acute professional suggestions, which together make this JDR special issue a valuable contribution to making our society more resilient to future disasters.

This special issue summarizes the main results of the latter half of a five-year project called SATREPS (Science and Technology Research Partnership for Sustainable Development) supported by Japan International Cooperation Agency (JICA) and Japan Science and Technology Agency (JST). The project title is “Development of a Comprehensive Disaster Resilience System and Collaboration Platform in Myanmar” and it is the first SATREPS project adopted in Myanmar. Yangon Technological University (YTU) is a major counterpart organization and both national and local governmental organizations are working together as strategic partners.

In the first half of the project, a database was constructed, composed of important data for assessing urban safety and disaster risk, such as the ground properties, and distribution of buildings, people, and traffic. Using the database, city development model and evaluation models for flood and earthquake risks were developed.

In the latter half of the project, combining these two evaluation models, a system was developed for discussing future damage differences due to different urban plans and countermeasures. Furthermore, regarding flood, near-real-time flood inundation simulation system was developed. Related to earthquake disaster, a support system was developed for implementation of efficient countermeasures for both pre- and post-disaster. For infrastructure maintenance, performance monitoring and maintenance methods were proposed. Finally, in order to continue research activities and promote a continuous utilization of project results, a consortium scheme in which industry, government, and academia can work together has been created.

We hope that our SATREPS project activities can contribute to proper urban development and improvement of disaster management issues not only in Myanmar but also in other Asian countries.
