A message for middle and high school students
Find something that you can say, I'll bet my life on this. It doesn't matter what it is. If you think that if it doesn't work out, you can find another way, you will gain courage. It's more satisfying than regretting not to try.

What was your favorite book as a child or a book that impressed you?
Basically, I was not good at sitting down, and I hated books...
My parents say I used to read Chronological Scientific Tables, and I also played with Nikoli puzzle books.
What do you like about physics?
The part that the results of the experiments are properly trusted without being overly concerned with the beauty of mathematics.
What is the driving force behind your research?
It feels like my expectation of myself and others as hoping it will be a little more like this, but my expectation has been repeatedly betrayed in a good way (and sometimes in a bad way), and it turns out the result is more interesting than I had expected. It may not be limited to the research.
A message for middle and high school students
Most of things are usually manageable, so just enjoy life for now. It is hard to find your own way to enjoy yourself later on.

I think I was curious to see all the different characteristics in a small flag.
What do you like about physics?
I think it's a good culture where everyone can frankly share their opinions and enhance each other's knowledge on the common research subject of nature.
Also, there is nothing like the joy of thinking about a theory and being able to figure it out.
What is the driving force behind your research?
It is how I can encounter ideas, knowledge, and values that I have never experienced before.
A message for middle and high school students

Neutrino Astronomy, Beyond Standard Model Physics
Astrophysical Neutrinos, Detector Development, Particle Physics
The biggest and tiniest objects of physics research are closely connected: Some elementary particles can only be created in extreme environments in the Universe. In order to search for these tiny and rare particles you need the largest particle detector on Earth which is IceCube.
What was your favorite book as a child or a book that impressed you?
I passionately read “The solitaire mystery” by Jostein Gaarder in elementary school, which was my start to think about philosophy and the universe.
What do you like about physics?
I always asked how things work and learned about biology and chemistry. But if you continue asking, you end up with physics, because it describes how the world fundamentally works. I like about physics that you would never stop learning.
What is the driving force behind your research?
Investigating the unknown is my passion. It is my believe that ”impossible" only means that you haven’t found the solution yet.

Physics of extreme environments in space
In the universe, there are extreme environments that can never be reproduced on Earth (e.g., a high-density star as the size of the Earth squeezed into the space of a spoonful). I study phenomena occurring
in such places that are beyond human imagination.
What was your favorite book as a child or a book that impressed you?
Sophie's World by Jostein Gaarder, which I encountered in high school, is an important book that taught me the joy of
thinking things through. Also, Kenji Miyazawa's "Ginga Tetsudo no Yoru" and "Tentai Shikosho" by Taruho Inagaki
sparked my interest in the universe.
What do you like about physics?
There are many things, but I like that I can discuss with researchers from all over the world in the language of
mathematics, and get answers that I would not have been able to get on my own.
What is the driving force behind your research?
The joy of discovery when it is like, “Am I the first person on earth to notice this?” Ninety-nine times out of a hundred,
I am wrong, but I enjoy learning new things when I verify them.
A message for middle and high school students
I think it is a good idea to try everything you are interested in until you are satisfied, no matter what form it takes.
I think the key to making it more enjoyable is to be aware of broad perspectives by discussing with various people
and not being self-centered.

What was your favorite book as a child or a book that impressed you?
The Old Kingdom series by Garth Nix - where the early 20th century meets the mythical, and the young heroine saves the hero. It was fascinating for me the way the heroine used music and art to master life and death, alongside her funny furry companion.
What do you like about physics?
Nature is full of exciting phenomena we have yet to describe, which keeps me curious. Just like a detective, I like how physics enables me to question, investigate (and occasionally discover the truth behind the fundamentals of our universe. To me, this is very fun and most fulfilling.
What is the driving force behind your research?
I think what drives me is perhaps similar across many people in research: to discover the yet-to-be-discovered, to debate ideas and collaborate with great scientists and to explain what we observe in the Universe to the best of our ability.
A message for middle and high school students
For you reading this, did you know nearly all of what makes you was once shining bright in a star or supernova? So remember to cherish and take care of yourself, never be shy to seek advice and support during challenges, and whatever your passion is, pursue your interests - and if it gets difficult, as a message of motivation - all you have to remember is to do your best.
