Message from Executive Director

Inherited and unchanging values

受け継がれる不変の価値

Noh is the oldest existing classical theater performancein the world. It was born in Japan about 650 years ago
and has since kept the old scripts, direction, composition,
choreography, and the vocalization and pronunciation oflines. Noh masks, costumes, and instruments from a longtime ago are still used today. In 2001, UNESCO declared
Nohgaku, meaning Noh and Kyogen, another classical theater performance, as a “Masterpiece of Oral andIntangible Heritage of Humanity.”
According to Mr. NAKAMORI Kanta, who is a Noh mainrole of the Kanze school, a member of the Nohgaku with Mr. NAKAMORI Kanta, Noh
Performers’ Association and the Association for Japanese Main Role of the Kanze school at
the Kamakura Noh Theatre, Japan
Noh Plays, and the Managing Director of the Kamakura
能観世流シテ方の中森貫太氏とNoh Theatre, Noh became a “theatrical performance that
ご一緒に
鎌倉能舞台にてwas forbidden to evolve” in the Edo period from 1603 to1868. The Edo government practiced a strict governance system called “Sankinkotai,”requiring each feudal lord to spend every other year in Edo, or current Tokyo, while alsoordered to keep their wives and children all the time in the capital, as sort of “hostages.”
However, when staying in Edo, those lords from different parts of Japan could not communicate with each other as they wished because there was no “standard Japanese” atthat time. The Edo government decided to introduce Noh as the solution to this problem.
It was used as a “ruler’s art” in which the lords had to learn Noh chanting, which became
their common language after they mastered the vocalization, pronunciation, and meaning of the words. They also acquired a resonant voice and refined movements throughthe process. Thus, arbitrary changes to texts, directions, and such were forbidden.
Noh underwent challenging times after the Edo era in terms of preserving its original
style. The samurai society, which happened to be Noh’s long-term guardian, collapsed
due to the Meiji Restoration. The control policies enforced in occupied Japan after theSecond World War aimed to eliminate traditional cultures in the country. I am very
impressed thinking about the extraordinary efforts they had to make to carry on theoldest classical theater performance in its original form in those hostile circumstances.
I was also very surprised to learn from Mr. Nakamori about the length of the Noh timescale. For example, a Noh flute, characterized by a wide musical range of unique sounds,
takes about 20 years to make. Moreover, it needs to be played for another 200 years toreach its optimal tuning. The same applies to Noh masks. The paint on the masks may
not always be in the desired condition when one receives them, but they continue using
them in the hope that they will look much better after 100 years as they are passed downfrom generation to generation.
Today, we are striving to create a sustainable and resilient society by integrating cuttingedge scientific knowledge and locally rooted wisdom in the midst of dynamic climaticand social changes and diversifying values. I find Noh’s wisdom insightful in this context.
It makes us revisit the importance of pausing to think about unchanging values andhanding them down to the next generation.

Contribution to the government-led SIP program in its 3rd period
戦略的イノベーション創造プログラム（SIP）第 3 期への貢献
ICHARM has joined the Cross-ministerial Strategic Innovation Promotion Program(SIP) the 3rd period, “Development of a Resilient Smart Network System against
Natural Disasters,” which is a 5-year project starting in September 2023 and fundedby the Cabinet Office of Japan.
ICHARM takes part in a sub-theme titled “Promotion of disaster prevention actions
based on risk information,” led by Professor YAMADA Tomohito of Hokkaido
University, which aims to find effective ways of utilizing risk information to induce
residents and private companies to take voluntary actions for disaster risk reduction
and prevention. This sub-theme is composed of the following three research topics:
1) the development of weather-related damage prediction technology at a basin
scale; 2) the development of water-related disaster damage visualization technology; and 3) the development of technology for evaluation and generation of real-time
disaster risk information that promotes self-directed disaster prevention actions.
ICHARM will mainly contribute to the second topic and develop and implement technologies capable of performing quantitative assessments of water-related disasterrisks to which the companies may be exposed and risks that may be reduced owing
to disaster prevention activities. It will also continue studying practical approaches
to guiding people in taking voluntary risk reduction actions, such as early evacuation, by providing an opportunity to experience a simulated flood situation using
virtual reality technology.
Public expectations are high in these projects since it has been pointed out thatchanges in individual and corporate behavior comprise core part of the project
outcome and directly contribute to the increase of local and national resilience todisasters. ICHARM is determined to do its best to accomplish the project goals in
corporate with other partner organizations.

During heavy rainfall, if a series of landslides and debris flows occurs in mountainous
areas, a large amount of sediment and driftwood can flow into river channels (Photo1). If such sediment and driftwood are transported downstream by flood flows, they
can cause significant damage there, as exemplified by the 2017 torrential rain disaster in northern Kyushu (Photo 2). ICHARM has developed a rainfall-sediment-runoff(RSR) model to predict such flood disasters involving large amounts of sediment anddriftwood. The RSR model analyzes three types of processes simultaneously: ① therainfall-runoff process using the RRI model developed in ICHARM; ② the sedimentand driftwood runoff entering the river channel due to landslides, debris flows, andslope erosion; and ③ the sediment and driftwood runoff process using a unit river
channel model, in which a river channel is modeled from a confluence to a confluence. Through integrated analyses of these processes, the amount of sediment, itsparticle size distribution, and the discharge of driftwood at any point in a watershed
can be estimated in a time series (Figure 1). This is the model that analyzes the

and driftwood runoff from awatershed based on dynamics
and can be widely used not
only for disaster prediction but
also for issues related to sediment transport in a watershed,such as dam sedimentation andcoastal erosion. The RSR model
has been incorporated into
the RRI model developed by
ICHARM, and the interface will
be developed and made available for public use in the future.

Research / Training & Education

Figure 1 The concept of the RSR model
図 1 RSR モデルの概要

To ensure the reliability of this model, it is necessary to investigate the validity of thecalculation results using data on sediment and driftwood discharge during disasters.
Although such observation data are seldom available in general, in the case of theTerauchi Dam, whose upstream area was damaged by the 2017 torrential rains innorthern Kyushu, the amount of sediment deposited in the dam was measured to beabout 1.1 million m3 and the amount of driftwood about 10,000 m3. Therefore, weapplied the RSR model to the Terauchi Dam basin and investigated the characteristics of the model by varying the parameters. The results indicated three importantcharacteristics. First, the boundary between the area analyzed as debris flow and thearea analyzed as sediment transport in the river channel should be set as a slope ofabout 10 degrees. Second, since there is an upper limit to the sediment transportcapacity of a river channel, the amount of sediment discharge increases only up
to a certain point according to the limit, even when the amount of debris flow issignificantly huge. Third, the amount of driftwood runoff through the channel isalmost proportional to the amount of debris flow. As a next step, we will test thismodel with other cases to make it more applicable to practical river management
and evacuation planning.

ターフェースを整備し、公開する予定です。
このモデルの信頼性を担保するためには、災害時の土砂・流木流出に関するデータを用いて計算結果の妥当性を示す必要があります。そのような観測データは滅多にありません
が、2017 年の九州北部豪雨で上流域が被災した寺内ダムでは、ダムに堆積した土砂量が約 110 万 m3、流木量が約 1 万 m3 であることが計測されています。そこで、寺内ダム流域に RSR モデルを適用し、様々なパラメータを変化させながらモデルの特徴について検討しました。その結果、(1) 崩壊・土石流として解析する領域と河道の土砂輸送として解析する領域の境界を勾配 10°程度に設定するのが良いこと、(2) 河道の土砂輸送能力には上限があり、土石流の流出量が一定程度を超えると、それ以上土砂流出量は多くならない、(3) 流木の流出量は土石流の流出量にほぼ比例して増加すること、などが分かりました 1)。今後、モデルの適用事例を増やし、河道計画や避難計画の実務に活用できるよう、検討を続ける予定です。

<Field Trip>

During the three-day field trip, the students visited the Watarase and Kinugawa river
basins, accompanied by Chief Researcher USHIYAMA Tomoki, Research Specialist
HARADA Daisuke, and officials from the Kanto Regional Development Bureau of the
Ministry of Land, Infrastructure, Transport and Tourism.
In the Watarase River basin, the students
were briefed about the basin’s history, which
included copper mining in the Ashio area,
which contributed to Japan’s rapid economic
development after the second world war, its
resulting environmental destruction, erosion
control and other reconstruction projects, andthe development of the Watarase Retarding
basin.

In the Ashio Environment Study Center
足尾環境学習センターにて

In the Kinugawa River basin, they learned about dam projects in its uppermost reach,
including dam construction and the Kinugawa Dam Network, which aims to coordinate multiple dams to control water storage for effective water use. They were also
given an overview of river improvement projects installing open levees in the upper
reach and continuous levees in the lower reach. In addition, they received explanations
about the 2015 levee breach and flood inundation and the subsequent restoration
project, as well as about non-structural flood control measures.
The trip was also a good opportunity to learn about Japanese culture. The students【学生からの声】

visited the Nikko Toshogu Shrine, which enshrines Tokugawa Ieyasu, the founderand first shogun of the Tokugawa Shogunate of Japan, who started the Tone River
Improvement project.
After the trip, the students submitted a report on what they learned during the visits,
including how they may be able to use it to solve problems in their countries. The
flowing comments are taken from their reports.

Comments from students

Student from Timor-Leste:
The site visit to the Watarase and Kinugawa Rivers provided us with valuable insights
into advanced techniques and infrastructure for river management, including theconstruction of dams, levees, dikes, and parks for evacuation emergencies. Japan’s
proactive approach to disaster response and infrastructure development, considering the various natural disasters it faces, serves as a model for other countries.
Student from Pakistan:
The dam monitoring mechanism wasexcellent. Especially when there is anearthquake, drone technology is usedby the dam staff to monitor landslides in
the reservoir periphery. Real-time monitoring of the dam and reservoirs withobservation cameras also amazed me. I
accessed their monitoring website using
the QR code that the dam staff gave us.
Pakistan also needs such steps to makethe monitoring mechanism effective.

Student from Malawi:
The Joso 2015 levee breach was due
to a flood overflow. The same scenario happened in Malawi during Cyclone
Freddy. The breaching of dikes wascaused by torrential rains and mudslides and affected 15 districts in theSouthern region. We also learned fromthe Joso case that the government has
been improving flood prevention measures, such as raising and reinforcing thelevees and installing gates and pumps.

JICA: a one-year master’s program, “Water-related Risk Management Courseof Disaster Management Policy Program,” and a three-year doctoral program,“Disaster Management Program.”

Since their launches, over 180 practitioners and researchers have completed
either of the programs. They have been practicing knowledge and experienceacquired through the training in various fields of work after returning to theirhome countries. This section is devoted to such graduates sharing information
about their current assignments and projects with the readers around the globe.
Jamyang Zangpo (Bhutan), who graduated from the master's program in 2021,
has kindly contributed the following article to this issue.

Jamyang Zangpo
Sr. Hydrology/Meteorology Officer
National Centre for Hydrology and Meteorology, Bhutan
The global disruption caused by the COVID-19 pandemic affected people worldwide. Amidst the widespread
despair and the challenging period, I seized a unique opportunity to pursue a master’s degree and enhance myqualifications. This was made possible through the Knowledge Co-Creation Program (KCCP) funded by the Japan
International Cooperation Agency (JICA) in 2020. The program, a collaboration between the International Centre
for Water-Hazard and Risk Management (ICHARM) and the National Graduate Institute for Policy Studies (GRIPS),
offers an intensive one-year master’s course. In September 2021, I successfully completed the course, earning amaster’s degree in disaster management with a focus on flood disaster risk reduction.
During my study at ICHARM, my master’s thesis was research
entitled “Impact assessment on extreme floods due to climate
and social changes in the Amochu basin, Bhutan,” conductedwith the guidance of Dr. MIYAMOTO Mamoru, a senior researcher of ICHARM and an associate professor of GRIPS. The study
area is located in the westernmost part of the country, and theriver basin is transboundary, partially shared by China in thenorth. The Phuntsholing Township Development Project (PTDP)
is underway in the downstream part of the basin, which necessitates such studies. The findings of my research suggest that
extreme floods would increase in both magnitude and frequency. Thus, improving the flood resiliency of the upcoming
town requires constructing adequate embankments (structural
measure) and installing an early warning system (non-structural
measure) with a well-designed drainage system.
After earning my master’s degree in Japan, I rejoined the National
Centre for Hydrology and Meteorology (NCHM), an autonomous
agency addressing hydro-meteorological service needs. Over the
past two years at NCHM, I’ve focused on various flood-related
activities to mitigate flood risk in the country. Notably, I participated in conducting flood risk assessment across the country,
which is a component of the Strengthening Risk Information for
Disaster Resilience in Bhutan project, funded by the World Bank
from 2021 to 2025. Presently, I’m actively engaged in developing
flood hazard maps using drone-surveyed high-resolution digitalterrain models at NCHM.

Training & Education / Information Networking

Another major activity in which I was involved extensively was developing a flood forecasting system called the
Flood Forecasting and Early Warning System (FFEWS), which was piloted in the Amochu basin and would soon bescaled up for the other remaining river basins of the country. The system integrates the existing hydrologic andearly warning stations, both manual and automatic, and produces hourly discharge forecasts at various predetermined forecasting locations.
Currently, I am working in close collaboration with JICA experts on the development of an early flood warning
system in the Wangchu basin funded under the JICA TCP-II project. The project is in full swing, and by the end of it,
Thimphu and Paro, two of the biggest towns in Bhutan, will be well prepared to deal with flood risk.
I would like to conclude this with a renewed sense of gratitude to ICHARM and the amazing faculty for extending
this wonderful opportunity to share a few things through which I, as an alumnus of this renowned institution, am
contributing to reducing flood risk in my country. Moreover, to both ICHARM and GRIPS, I extend my deepest
appreciation for conferring me with a master’s degree. Finally, I wish both institutes the best in whatever steps you
take forward in the future.

On November 15, 2023, a group of about 40 young professionals from the Netherlands
visited the Public Works Research Institute (PWRI) and discussed views and ideas on
various issues with their Japanese counterparts. They are currently working at fivegovernment organizations: the Ministry of Infrastructure and Water Management,
the Department of Waterways and Public Works, the PBL Netherland Environmental
Assessment Agency, the Human Environment and Transport Inspectorate, and the
Authority for Nuclear Safety and Radiation Protection.
The meeting with ICHARM, taking place at its auditorium and moderated by Chief
Researcher KURIBAYASHI Daisuke, began with Mr. Jeroen Deurloo, the leader of the
Dutch delegation, introducing the visiting group to ICHARM researchers. Deputy
Director MORI Noriyuki followed, outlining the organization and activities of ICHARM.
After that, four ICHARM researchers took turns presenting their research: SeniorResearcher Mohamed Rasmy Abdul Wahid on the long-term runoff analysis system;
Research Specialist Shrestha Badri Bhakta on agricultural risk assessment under climatechange in Indonesia; Researcher KAKINUMA Daiki on flood forecasting for Japan’s
small- and medium-sized rivers; Senior Researcher MIYAMOTO Mamoru on the Online
Synthesis System for Sustainability and Resilience implemented in the Philippines.
Representing the Dutch delegation, Ms. Louise-Ann Zaat of the Ministry of
Infrastructure and Water Management spoke about water management in Dutch
rivers and future challenges. Taking the Meuse River, for which she is in charge, as an
example, she explained that a further increase in river flow is predicted due to climatechange during the winter when the flow is usually high, while a further decrease is
projected during the summer when it is usually low. To reduce such impacts, they plan
to expand the cross-sectional area of flow by river excavation and heighten the levees
to increase the river’s flow volume for the dry season.
The participants on both sides asked each speaker many questions, and the meeting
lasted far longer than scheduled. Director for Special Research MITSUHASHI Hisashi
ended the event by thanking them for their active participation.
The Dutch visitors also spent the afternoon having meetings with the researchers of
two other research centers of PWRI: the Center for Advanced Engineering Structural
Assessment and Research (CAESAR) and the Innovative Materials and Resources
Research Center (iMaRRC). It was the first time in a long time that PWRI had received
such a large group of Dutch professionals. The exchange of views and ideas with them
was an excellent opportunity for Japanese researchers to realize that both sides sharecommon issues.

Visit by World Bank officials
世界銀行グローバル水本部長と意見交換を実施
On November 20, 2023, with support by the Japan Water Forum, three World Bank
officials visited PWRI and discussed views and ideas with PWRI President, ICHARM
Executive Director, MLIT HQs Director, Japanese experts for disaster risk management,
and ICHARM students. The group included Mr. Saroj Kumar Jha, the global directorof Water Global Practice, Ms. Sarah Nedolast, the program manager of Global Water
Security and Sanitation Partnership, and Ms. Eileen Burke, the global lead of Water
Resources Management. Mr. Jha is an experienced expert in water and disaster management and participated in establishing the Global Facility for Disaster Reduction
and Recovery (GFDRR), which the Japanese government supports as a partner.
The meeting was held in two parts. In the first part, the visitors had discussions withJapanese experts including FUJITA Koichi, the president of the Public Works ResearchInstitute (PWRI), KOIKE Toshio, the executive director of ICHARM, and KONAMI
Takahiro, the head of the International Affairs Office of the River Planning Division,
the Water and Disaster Management Bureau, the Ministry of Land, Infrastructure,
Transport and Tourism. The ICHARM executive director began the meeting by outlining the research, project, and other activities of ICHARM, followed by the World Bank
staff asking questions and speaking about related issues. The following are some ofthe points Mr. Jha mentioned in the meeting:• The world has recognized Japan as a global leader because it
recovered from the devastation after World War II by utilizing
support from the World Bank and other nations and because thecountry has shared such experiences with other governments.
In this sense, the World Bank has tremendous respect for Japan.

• In Africa, many people have no access to drinking or clean water.
Projections have suggested that the number of such people willreach 100 million in Eastern South Africa alone.

Mr. Saroj Kumar Jha
サ ロ ー ジ・ ク マ ー ル・ジャー本部長• The World Bank has set a new vision, “World Free of Poverty on
a Livable Planet.” It defines a “livable planet” as a place where
everyone has access to clean water and that is equipped withirrigation to prevent extreme flooding or drought.
• The new vision of the World Bank includes a reference to water,which never happened in its history. The World Bank has listed
water security among its six global issues. The organization is
profoundly aware of climate change, which worsens the worldwide crises in water security and access.

Ms. Eileen Burke
アイリーン・ブルケ
グローバル・リード• Even though the World Bank prioritizes water in its mission, theeffort will only be worthwhile if political leaders in developed
countries see water as a priority issue.
• Every national government needs to enhance water-related
efforts, such as more investment. However, more importantly,
they need to encourage the private sector to invest more inwater issues. It is only possible to solve the water security problem with the investment from the private sector.

In response to Mr. Jha’s
comments, agreeing thatwater is a crucial issue
to most countries, Mr.
Konami mentioned thatclose cooperation with
the World Bank in thisarea can be an excellent
opportunity for Japan. He
said that it would demonstrate to the world that

The Public Works Research Institute(PWRI) offers an outreach program inwhich staff members visit schools andcommunity groups to deliver talks ontheir respective fields of expertise. As partof this program, MITSUHASHI Hisashi, thedirector for special research of ICHARM,
spoke about global efforts and challenges
in mitigating water-related disaster risks
on November 8, 2023, at the Zoshigaya
Community Cultural Creation Center inToshima City, Tokyo, for the Chitosebashi
Community School consisting of people
who live, work, or go to school in the ward.

Mr. MITSUHASHI opened his talk by pointing out various water issues currently faced
around the world, including floods, droughts, water pollution, and coastal erosion,
while showing photos of the Bagmati River in Nepal, the Syr Darya River in Uzbekistan,and the Volta River in Ghana.
Following the introduction, the speaker moved on to the first topic of his presentation,“Relationship between People and Rivers in Japan.” He explained that Japanese rivers
have a much higher flood peak flow rate than those in Europe and America and thatJapan’s population and industries are concentrated in alluvial plains, which are often
exposed to high flood risk. Taking the Ara River as an example, he then introduced
various flood control measures used for Japanese rivers and major projects under the
new policy, River Basin Disaster Resilience and Sustainability by All.

In the second topic, titled “Kanda River: Now and Future,” he talked about the most
locally well-known river in Toshima City, the Kanda River. He discussed the Kanda River
Improvement Plan, including how river improvement projects would reduce the floodrisk. He also suggested what the residents should do in time of flooding by showing
them a video created by the Tokyo Metropolitan Government.

The speaker concluded his talk with the third topic, “Global Initiatives and Challenges
for Water-related Disaster Reduction.” He first addressed three key concepts in
disaster risk management: “mainstreaming of disaster risk reduction,” “pre-disaster
investment,” and “build back better in reconstruction.” He then explained that Japan
has been practicing disaster management policies based on these concepts andemphasizing their importance in various international settings, which has been internationally recognized today. He also presented an ongoing project conducted in thePhilippines based on the three concepts.
The audience attentively participated in the two-hour-long session. Some seemed tolearn new information by taking a fresh look at the Toshima City Flood Hazard Map,
while others asked questions about the definition of the first class river and whether any flood prevention measures had been in place for the underground shopping
center in Ikebukuro. All these indicated that the participants were highly interested infloods, as well as other water-related disasters.

While informative for the audience, the program was also a great opportunity for
ICHARM and PWRI to help people understand the contribution their work makes
to society. It was grateful for the occasion and thanked the Zoshigaya Community
Cultural Creation Center for giving us this opportunity.

PWRI is ready to deliver this outreach program on an as-needed basis for a wide variety of audience from elementary students to the general public. For details on how to

講座の様子
response to the request
made by the elementary school. The fifth graders had been studying how flowing
water affects the surrounding environment, and the school set up the event toprovide an opportunity for them to learn more about water-related disasters aroundthe world and various efforts to reduce the damage caused by them.

The lecture was about 40 minutes, consisting of four themes, including some fun
quizzes: 1. Flowing water affects the environment; 2. Too much rain causes flooding;
3. The world works together to reduce flood damage; and 4. Everyone can help
reduce flood damage.

In the first theme, the speaker reviewed what the students had learned about
flowing water: eroding land and transporting and accumulating soil. In the second
theme, he let the children watch movie clips about two past flood cases: the 2015
flood that caused significant damage near Tsukuba City and the 2021 flood thatinundated the Zhengzhou subway in Hebei Province, China. They were amazedto see how violent water can be. In the third theme, the students learned about
worldwide cooperation in flood damage reduction. They learned that internationalorganizations, such as the United Nations, UNESCO, and the World MeteorologicalOrganization, and domestic organizations, such as Japan’s government agencies,
including ICHARM, have been working together in this effort. In the fourth theme,
the speaker talked about what children can do to protect themselves from flooding.
He advised them to check a flood hazard map and informed them of some othertools they can use for the purpose, such as “My Timeline (a tool to plan one’s action
in time of flooding),” “River Disaster Prevention Information (a portal site about riverdisaster information),” and the “‘Run for life’ alert system (a push-type alert system
to encourage early evacuation).”
After the lecture, the students answered a simple questionnaire. Of them, 68%
found the lecture “Very interesting,” and 26% “Fairly interesting.” When asked about
why they chose these answers (they were allowed to select multiple answers), 80%
selected “The lecture was very informative,” and 67% “The lecture included video
clips and quizzes.” Overall, their positive responses suggested that the lecture successfully provided the young students with a meaningful learning experience.

This event also provided ICHARM with an excellent outreach opportunity. It was
grateful for the occasion and thanked the teachers of the Takezono-nishi Elementary
School and the Tsukuba City Lifelong Learning Promotion Section for their cooperation in making it happen.

編集後記
Happy New Year!
I am writing this editorial note in mid-December. Although it is still relatively
warm during the daytime, the temperature in Tsukuba City is gradually dropping,and I see beautifully colored gingko trees here and there around the city.
The world has steadily returned to pre-Corona daily life after the long pandemic.
What kind of year was 2023 for you?
On a personal note, I was transferred from Hokkaido to Tsukuba City last April.
Staying busy, while sometimes bewildered by various changes in the new environment and sometimes refreshed by them, I felt like the year had ended in the blinkof an eye.
Speaking of changes in the environment, ICHARM welcomed new doctoral andmaster’s students last October, as mentioned in the educational program updates reported in a newsletter section in every issue. I assume that they might begoing through a lot of confusion and worries as they study in a new environment
in Japan, far away from their home countries. All staff at ICHARM hope that their
daily endeavors will blossom in the future. We will continue to update the readerson their efforts through our newsletter.
We hope that 2024 will be a wonderful year for all of you.
