祝辞 /Congratulatory speech

2026年3月(令和7年度)の社会基盤学専攻学位授与伝達式で、川崎が教員祝辞を述べました。以下にその文面を掲載します。

Kawasaki delivered the Congratulatory Speech at the graduation ceremony for the Department of Civil Engineering in March 2026. The English text of his speech is provided below. Please note that the content is primarily intended for Japanese students.

---------------------------------------------------
修了生の皆さん、本日は大学院修了、誠におめでとうございます。
ご家族をはじめ、皆さんを支えてこられた関係者の皆様にも、心よりお祝いを申し上げます。社会基盤学専攻で積み重ねてきた学びと努力に、教員の一人として深い敬意を表します。

社会基盤学が向き合うのは、道路や河川、都市といったインフラであると同時に、人々の暮らしの安全、そして公正です。

ここで少し、私自身の話をさせてください。

近年、東京大学の入学者の出身校には偏りがあり、首都圏の中高一貫校出身者が多い、と言われています。しかし私は宮崎南部の出身で、家族・親戚で大学に行った人はおらず、裕福な家庭でもありませんでした。塾に通ったことはなく、新聞配達をしていました。

それでも今、東京大学で教授として仕事ができています。
努力はもちろんですが、出自だけで将来が決まりきらない余地を残してきた
日本社会と教育の仕組みに、心から感謝しています。

一方、私の研究対象である発展途上国では、経済格差が大きく、機会が一部の人に限られている国が少なくありません。地方や農村に生まれたというだけで、高等教育は現実的な選択肢になりえないことが多いです。

さらに風水害などが重なると、貧困の悪循環が加速することがあります。
私はこの悪循環を少しでも軽減したいと考え、途上国の治水政策が貧困や社会的不平等の削減にどう結びつくかを研究しています。

日本では、風水害や地震・津波という厳しい自然条件の中で、河川・海岸整備や耐震化などの公共投資により、社会基盤が積み上げられてきました。現代の日本では、その膨大で高度な施設に守られていることは、かえって気づきにくいかもしれません。

しかし、その「当たり前」があるからこそ、皆さんは勉学に集中でき、企業は経済活動を展開し、社会は日々の暮らしを回すことができます。
その「当たり前」を次世代に渡す責任が、私たちの仕事です。

皆さんはこれから、多様な分野に進まれるでしょう。近年は、金融機関や総合コンサルなど、社会基盤学と直接は結びつかない領域へ進む方も増えています。

私はそれを前向きに捉えています。
社会の意思決定が行われる多様な場所に、社会基盤学の修了生が広がっていくことは、社会にとって大きな価値があるからです。

ただし、その“広がり”が本当に意味を持つためには、皆さんがこの専攻で手に入れたものを、手放さないことが大切です。

皆さんが専攻を選んだとき、「社会」「基盤」「公共」という言葉に、強い関心や手応えを感じていたはずです。どんな業界にいても、最終的に社会に残るのは、「それが誰の役に立ち、誰の負担になったのか」という結果です。

ここで一つだけ補足します。

皆さんの努力は本物です。
しかし、教育・治安・医療・インフラといった面で、世界的に見て非常に恵まれた環境の中で育ってきたことも忘れないでください。もし皆さんが、途上国の農村で生まれていたなら、その能力を十分に発揮することなく、人生を終えていたでしょう。努力が大切であることと、機会が偏在していることは、両方が真実です。

だからこそ、皆さんがこれから得る影響力には、使い道があります。そのために、重要な意思決定の前に、心の中で問いを一つ追加してください。「この決定は、弱い立場の人を置き去りにしないか。」
自分と異なる立場の人の状況を考えることは、簡単ではありません。しかし、皆さんの知識と思考力を総動員すれば、想像できるはずです。

最後になりますが、どうか高い志と能力を、自分のためだけでなく、社会のため、そして未来のために使ってください。

皆さんのこれからの活躍が、日本と世界のよりよい公共を形づくることを心より願い、お祝いの言葉といたします。

本日は誠におめでとうございます。

To all our graduates, congratulations on your graduation from the graduate school today. I would also like to extend my heartfelt congratulations to your families and everyone else who has supported you throughout your journey. As a member of the faculty, I express my deepest respect for the knowledge and hard work you have accumulated in the Department of Civil Engineering.

 Civil Engineering deals not only with infrastructure such as roads, rivers, and cities, but also with the safety and fairness of people’s lives.

 Please allow me to share a brief personal story.

 In recent years, it has been said that there is a skew in the high schools of origin for students admitted to the University of Tokyo, with many coming from integrated junior and senior high schools in the Tokyo metropolitan area.

 However, I am from southern Miyazaki; no one in my family or among my relatives attended university, and my family was not wealthy. I never attended a cram school; instead, I delivered newspapers.

 Yet here I am today, working as a professor at the University of Tokyo.
 While hard work certainly played a role, I am deeply grateful to the structure of Japanese society and education, which has preserved the possibility that one’s future is not entirely determined by one’s background.
 I am truly grateful to the Japanese social and educational systems for this.

 On the other hand, in the developing countries that are the subject of my research, there are many nations where economic disparities are vast and opportunities are limited to only a select few. Simply being born in a rural area or the countryside often makes higher education an unrealistic option.

 Furthermore, when natural disasters such as typhoon and flood damage strike, the vicious cycle of poverty can accelerate. I want to help alleviate this vicious cycle, even if only slightly, and am conducting research on how flood protection policies in developing countries can contribute to reducing poverty and social inequality.

 In Japan, despite harsh natural conditions such as typhoons and flood damage, earthquakes, and tsunamis, civil infrastructures has been built up through public investment in river and coastal protection and earthquake-proofing. In modern Japan, it may be difficult to realize just how much we are protected by these vast and sophisticated facilities.

 However, it is precisely because of this “normality” that you are able to concentrate on your studies, companies are able to conduct economic activities, and society is able to function day to day.
 Our job is to fulfill the responsibility of passing this “normality” on to the next generation.

 You will all go on to pursue careers in a variety of fields. In recent years, an increasing number of you have chosen paths not directly linked to Civil Engineering, such as financial institutions and general consulting firms.

 I view this as a positive development.
 This is because having graduates of Civil Engineering spread out to the diverse places where societal decisions are made holds great value for society.

 However, for this “spread” to truly be meaningful, it is important that you do not let go of what you have gained in this Department.

 When you chose this department, you must have felt a strong interest in and connection to the words “civil engineering” “society” and “public.” No matter what industry you enter, what ultimately remains in society is the result: “Who did it benefit, and who did it burden?”

 I’d like to add just one thing.

 Your efforts are genuine.
 However, please do not forget that you have grown up in an environment that is, by global standards, extremely privileged in terms of education, public safety, healthcare, and infrastructure. If you had been born in a rural area of a developing country, you would likely have ended your life without ever fully realizing your potential. It is true that effort is important, and it is also true that opportunities are unevenly distributed.

 That is precisely why the influence you will gain from now on has a purpose. To that end, before making any important decisions, please ask yourself one additional question: “Will this decision leave those in vulnerable positions behind?”
 It is not easy to consider the circumstances of those in a different position from your own. However, if you mobilize all your knowledge and critical thinking, you should be able to imagine it.

 Finally, I ask that you use your high aspirations and abilities not only for your own sake, but for the sake of society and the future.

 It is my sincere hope that your future achievements will help shape a better public sphere for Japan and the world, and I offer these words as my congratulations.

 Congratulations on this special day.

Lost in Uppsala (not in direction, hopefully not in research)


Hej! This is Budz again.

I've spent the last two weeks getting lost at Uppsala University, not literally lost (thanks, Google Maps!) but lost in its incredible history and atmosphere. I want to express my huge thanks to the Musha Shugyo Program of the School of Engineering, UTokyo, for this incredible opportunity, and of course, to Prof. Giuliano Di Baldassarre for his hospitality and guidance.





 

 Two seasons within two weeks? Feb 25 vs. Mar 5


My short stay in Uppsala provided a vital external lens for my PhD research. The feedback from Prof. Di Baldassarre and LUVS has been instrumental in refining my direction. Moving forward, we have identified two key research gaps to tackle: (1) challenging the homogeneity assumption in current socio-hydrologic models by integrating survey data to capture the diverse flood impacts and recovery patterns, (2) conducting sensitivity analysis on various economic loss models within flood risk monetary estimation. I'm still in awe of how most researchers I met here share a genuine curiosity for connecting scientific findings to the community, whether through socio-economic improvement or policy recommendations.



While my primary mission was gaining feedback on my research, I've been using my breaks to get lost with the history of this country. Founded in 1477, Uppsala is the oldest university in Scandinavia, the home of legends like Anders Celsius and Carl Linnaeus. I'm amazed by how they have preserved the past, from the ancient architecture to the vast library collections. I visited the Uppsala Domkyrka, the largest cathedral in Scandinavia, and the Botaniska trädgården , where it was impressive to see tropical plants thriving even in the Swedish climate!





Since Stockholm is only a 40-minute train ride away, I even managed to sneak in on a sunny Sunday exploring Gamla Stan and the Vasa Museum.







Everything here feels brand new to me, and I've tried my best to capture every moment. Since I can't upload everything (as much as I'd like to 😂 HAHA), I've put together a one-minute reel of my Uppsala and Stockholm solo adventures. Please be kind just tried it today✌️LOL





I hope you enjoy it, and I promise to share more in my next blog! Perhaps about the Fika culture and the conference that coincidentally took place in Uppsala during my stay!

HyDEPP-SATREPS Colloquium 2026

Kumusta? This is Budz again!

Last February, I joined Kawasaki Sensei at the SEARCA Headquarters in the Philippines for the HyDEPP-SATREPS Colloquium 2026. The event, a collaboration between the University of Tokyo and the University of the Philippines Los Baños, focused on presenting various research related to its theme: “When Water Strikes: Building Climate-Resilient Communities Through Hybrid Water Disaster Risk Assessment Technologies.”




During the plenary sessions, Kawasaki Sensei shared insights from the lab's localized assessment initiatives to better understand the relationship between flooding and poverty in Southeast Asian countries. I also had the chance to share a chapter of my PhD research on the development of flood resilience curves and was honored (and lucky) to be named one of the best presenters among the student participants.







Supported by JICA and JST, the colloquium emphasized turning scientific data into actionable, sustainable policy. I'm grateful for this opportunity to share our work and contribute to this initiative!

Field survey from my perspective Part 2 ~Accra~

Hi this is Risako, M1 in Kawasaki Lab. This is part 2 of my trip blog!

Day 5

Drive to Accra. It was actually the 1st of January, and the prof. Kawasaki and my friend Eyad went to see the sunrise from Gulf of Guinea!! I missed it bc I was sooo sleepy ;;) Maybe next time :)

At night we had a new year feast at a nice Japanese restaurant. And we got special new year present from the hotel!



Day 6

First survey day in Accra. We had another meeting with enumerators for Accra. There were less questions asked than in Keta so I was a bit worried.


Day 7 

Survey day! The field was more crowded than in Keta and less breeze so I made sure that everyone including myself was hydrated and had some rest in the middle. 
This time, we had a bit more flexible system to support enumerators. We, university staffs, split up and followed different enumerators so that we can support every one of them as soon as possible. That's significant growth, even in such a short period. 




Day 8

Sunday was off! I slept like mud X0 

We had an excellent dinner in an Italian restaurant Tomato.


Day 9

Second survey day! I don't remember much, but we were walking all over the area wandering in houses structured like a maze. 


Day 10

Last survey day!! I felt I was getting a little tired and couldn't be active till the end of the day. I was very thankful that other staff members worked a lot when I couldn't.

For dinner, we celebrated the success of the field survey in a restaurant with live music! We danced to Ghanaian traditional songs:)





Trip finished! I really appreciate everyone who supported this survey, namely, JST and JICA for funding, JICA officer Takano san for the arrangement, Ghanaian profs and students for the arrangement and support, my fellow enumerators for working hard under the harsh weather and being patient with the long questionnaire, prof. Kawasaki for giving all kinds of advice and support, and finally Eyad for being my best teammate. Yet, the research has not finished; we are expecting another survey in May, so let's keep up!!
