A Day of Challenge, Encouragement, and Growth — Mt. Ogusu Hiking Event

Last weekend, we held a special hiking event together with families from “LaLaLand nursery school,” operated by our group company. More than 30 YBS families joined us as we set out to reach the summit of Mt. Ogusu, the highest mountain in Yokosuka!!

For children, the hike from the starting point to the summit takes about an hour. Along the trail, the children enjoyed collecting stamps at checkpoints while making their way up the mountain step by step.

Participants from YBS ranged from tiny one-year-olds to energetic middle school students, along with many parents and family members. Some families even took on the challenge while carrying newborn babies!

Although these different age groups do not often interact during regular school life, the experience of facing nature together naturally brought everyone together as “One Team”.

“You can do it!”

“We’re almost there!”

“Be careful, it’s slippery!”

Warm encouragement filled the mountain trail from both children and adults, helping one another during difficult moments.

It sounds simple, but through real challenges in nature, the children were learning what it truly means to care for and support one another.

For many of the younger preschool children, climbing uneven mountain stairs and steep slopes was a huge adventure and an incredible challenge in itself.

The path was long and difficult. At times, some children looked ready to give up. Yet beside them were parents gently encouraging them with words like:

“You’re doing great.”

“It’s okay, you can do it.”

It was deeply moving to see children giving their absolute best in the middle of nature, supported every step of the way by the love and encouragement of their families.

Meanwhile, the middle school students quickly reached the summit with impressive energy. But their challenge did not stop there…

“We’re going to do another round!”

After reaching the top, they immediately set a new goal for themselves and ran back down the mountain to continue.

Inspired by the older students pushing beyond their limits, the elementary students also decided to challenge themselves together.

When we asked them,

“Why do you want to go up so many times?”

they confidently answered,

“We just want to challenge it! I think we could even do it three times!”

The confidence in their eyes was powerful. They had created their own goals and truly believed they could achieve them.

In today’s world, technology continues to make life easier and more convenient. Without realizing it, both children and adults are slowly becoming more distant from “difficult” experiences in daily life.

That is why seeing children excitedly take on the challenge of climbing a mountain felt incredibly powerful and inspiring.

“Giving it our all”

“Supporting one another”

“Challenging themselves beyond the limits they thought they had”

“Experiencing the incredible feeling of saying, “We did it!””

We believe that these kinds of real-life experiences help children grow stronger, kinder, and more confident as they continue taking on new challenges in life.

What a beautiful day and unforgettable experience we all shared together!

YBS Sports Day – Growth, Courage, and Community

YBS Preschool and Elementary had an exciting and memorable Sports Day last Friday.

In Japan, Undokai (Sports Day) is one of the biggest school events of the year. It is not only a day of physical activity, but also an important opportunity for children to develop teamwork, perseverance, responsibility, and a sense of community.

Through the universal language of movement and sports, children experienced growth, joy, and a wide range of emotions throughout the day.

Our Preschool children embraced the theme “Living in Color,” expressing their individuality and unique strengths in their own special ways. With courage and enthusiasm, they stepped into the large gym at the Dental University, many for the very first time performing in front of a big audience.

Some of our younger children felt nervous and even shed a few tears when separating from their parents, but they showed incredible bravery by staying, participating, and doing their very best.

As the leaders of the preschool, the Pythagoras class showed truly remarkable growth. Not long ago, many of them were the youngest ones, looking up to the older students — and now, they stood proudly at the front, guiding the entire preschool with confidence.

From delivering the opening speech with clear, strong voices, to their powerful taiko drum performance that echoed across the gym, to the spirited Soran Bushi dance filled with energy and pride, and finally the thrilling relay that brought everyone together — every moment reflected how much they have grown.

There was a sense of responsibility in their actions, a quiet confidence in their presence, and a deep care for their friends. They weren’t just performing — they were leading, supporting, and inspiring others.

Meanwhile, our Elementary students brought the field to life with their theme, “The Battle of the Four Houses,” inspired by Harry Potter. Divided into houses, students worked together across age groups, demonstrating unity, determination, and pride. It was especially inspiring to see them come together beyond age differences, supporting one another and striving toward a shared goal as one team.

As part of the Elementary Sports Day, parents also joined in for a tug-of-war, adding a fun and lively moment to the day.

What stood out most, however, was the children — cheering with all their hearts, calling out to their parents, and supporting them with genuine excitement and pride. Even in moments where they were not the ones competing, they remained fully engaged, showing encouragement, empathy, and strong team spirit.

Through these experiences, children learn that growth is not only about their own performance, but also about supporting others and being part of something bigger than themselves.

As they grow older, the ability to believe in themselves, take on challenges, and stay passionate remains just as important. By continuing to challenge themselves, they discover new possibilities and build lasting confidence.

It was a meaningful reminder that while children are at the center of Sports Day, the spirit of growth, connection, and courage is shared across the entire community.

Throughout the day, children experienced the excitement of winning, the frustration of losing, and the courage to continue trying. Just as importantly, they learned to cheer for their friends, celebrate each other’s efforts, and embrace every moment with resilience and sportsmanship.

Sports Day was more than just a day of competition — it was a meaningful opportunity for every child to grow, connect, and discover something new about themselves.

We are incredibly proud of all our students for their courage, teamwork, and spirit. It was truly a beautiful reflection of the YBS community.

A story of YBS staff : Yuka Sensei~Believing in Infinite Potential and Leading with Authenticity~

Meet Yuka sensei,  a new YBS preschool principal. With 21 years of experience in early childhood education, she has seen it all. But she describes her last 1.5 years at YBS as “life-changing.” As she steps into her new role  on April 1st, we sat down to talk about her journey, the fear of change, and the beauty of “letting go.”

— What inspired you to become a preschool teacher? 

It started with my own kindergarten teacher. As a child, I felt out of place and struggled to understand why I had to go to Yochien ( Japanese Kindergarten ).  But my teacher opened her heart to me and accepted me exactly as I was. That changed everything. In my graduation picture book, I wrote, “I want to be a preschool teacher.” For 21 years, I’ve never looked back.

 

— With your 21years journey,  is there a specific moment that shaped your philosophy?

 Two moments stand out. One was during a relay race at a school I was teaching as a class teacher. I was obsessed with winning and pushed the kids hard. We were the fastest in practice, but on the big day, we lost at the very end. I was devastated and felt a heavy sense of responsibility as their teacher.

But when we got back to the classroom, the kids weren’t blaming anyone. They were saying, “I wish I ran faster!” and “Let’s try harder next time!” I was the only one stuck on being ‘Number One.’ The children had already moved on to something better: teamwork. It was a humbling lesson in my own immaturity.

The second was a student with autism. I had assumed there were things he simply “couldn’t do.” But during the graduation ceremony, he caught my eye, waited for my signal, and performed perfectly. It was my ego that had placed limits on him. Children have infinite potential if we just believe in them.

 

Facing the Unknown at YBS

— How did you feel when you first joined YBS?

Honestly, I was terrified. I had spent my entire life in traditional Japanese environments. Suddenly, I was in a world of English, diverse cultures, and international staff. I thought, “There’s no way I can survive here.” After years of being a principal at previous schools, I suddenly felt like I didn’t know anything. It was the biggest crisis of my career.

 

Letting Go of “The Rules”

— How did you change during your time as manager? 

It’s not an exaggeration to say my life changed. The biggest shift was letting go of being bound by “the right way” or rigid rules. At first, I tried to force Japanese rules on the international staff. It didn’t work. One day, I asked myself, “Is this rule actually necessary?” When I realized it wasn’t, I became flexible. My heart felt lighter. 

The same went for the language barrier. I used “not speaking English” as an excuse, but I learned that if you communicate with your whole heart, you don’t need a translator. Those raw, honest moments built the deep trust I have with my colleagues today.

 

The Future at YBS

— What is your vision?

 I want YBS preschool to be a place where everyone can truly be themselves. In the past, I felt I had to suppress my personality to “be professional.” But YBS is a place that says, “Be yourself!!” . I want our children to grow up proud of who they are and unafraid to live authentically. To achieve that, our teachers must first lead by example and shine as individuals.

And I would like to provide many opportunities for international children to learn Japanese, feel and experience Japanese culture. I already have seen many YBS children becoming bilingual, and I would like to make memories and skills together that they can carry with them wherever they live in the future.

 

— A final message for our parents and staff?

To Parents: Childhood happens in the blink of an eye. I want to share those fleeting moments of growth with you and involve you as vital members of our team. I am so looking forward to sharing our children’s moments with you. And don’t hesitate to communicate with me if you have any questions even if it’s a little thing.

 To Staff: Education is a never-ending “challenge.” There are no easy answers, and sometimes we have to face our own flaws. But let’s overcome them together and build something new! We can do it!!

 

What is “Early Education” to you?

“It is a Challenge.” You cannot do it alone. It takes colleagues, children, and parents working as one. It requires us to involve others, show our true selves, and constantly outgrow who we were yesterday.

At YBS, I feel I have finally started running as my true self. I am so excited for the moments ahead and grateful to everyone taking this journey with me.

YBS will continue to challenge the status quo, believing in the infinite potential of every child as they prepare to take on the world.

YBS Students Shine at the American Math Olympiad

Later in 2025, we had the opportunity to participate in the American Math Olympiad (AMO), a globally recognized mathematics competition that challenges students with advanced, non-routine problem solving and critical thinking beyond standard grade-level expectations.

And we are so proud to announce that two of our students received awards! — one of our 3rd graders earned a Bronze Award, and another 3rd grader received an Honorable Mention.

When we received the results, we couldn’t have been more proud!! We celebrate not only their achievement, but also their courage to take on this challenge and their achievements. 

This was the very first time for YBS to take on the Math Olympiad.
Before the competition, as we looked through the sample questions, we honestly felt uncertain about how far our students could go….even our math teachers were scared….the first wall  begins with thinking flexibly and truly understanding each question.

But our students were so brave!!  When the students faced the challenge, their expressions were filled with focus and determination. Even when the problems were difficult, they never gave up. They kept thinking, pushing forward, and trying until the very end.

In that moment, all of our doubts disappeared.

And this is not just the story of the award winners.

For those who received awards, those who didn’t, and the teachers who stood beside them — this experience holds deep meaning for all of us. It was about having the courage to step beyond uncertainty and take on something new.

And through this journey, something even more important was born.

A new goal.
A stronger belief.
A shared determination to take on the next challenge — and aim even higher!

We will continue to grow, to challenge ourselves, and to move forward together.

Congratulations to our award winners, and to every student who took on this challenge!

Our proud students taught us the true meaning of never giving up, having courage, and not limiting our potentials.  

YBS Featured in International School Times!

We’re excited to share that YBS has been featured in International School Times, a media platform spotlighting the latest in international education in Japan!

In the article, YBS founder Ms. Fumi talks about our new partnership with a dental university, our growing collaboration with higher education, and our vision for connecting Asia and the world—along with what’s next for YBS.

Our goal is simple: to create meaningful, high-quality bilingual learning experiences that open up new possibilities for every student, wherever they go in the world.

Beyond that, we hope to make a lasting impact by empowering students to carry their educational experiences in Japan forward as they take their next steps on the global stage!

Growing Proudly Beyond Borders: Katie’s Story After YBS

We recently reconnected with our YBS graduate, Katie — the very first American student at YBS. She played a meaningful role in shaping our journey toward becoming a truly bilingual school. She became fluent in Japanese (yes, she even debated with teachers in Japanese!).

Now she is 16, and still carries the same bright smile and thoughtful heart — only now paired with a quiet confidence and a clear sense of direction.

Today, Katie was selected and enrolled at the highly selective The Gatton Academy of Mathematics and Science, an early college program housed at Western Kentucky University.

Each year, students from across Kentucky’s Commonwealth apply through a rigorous selection process. From applicants representing schools in 47 counties, only 98 students are chosen.

Katie is one of those 98!!!

At just sixteen, she lives on campus and takes a college course load. By graduation, she will earn both her high school diploma and an associate’s degree — a remarkable achievement that reflects not only academic excellence, but courage and vision.


What Did YBS Mean to Her?

When I asked Katie what she remembered about YBS, her face softened. She didn’t answer right away — she smiled first.

“I remember just walking around and talking with people,” she said.

“Having fun. Every day.”

She laughed as she mentioned the small outdoor balcony playground — that little space that somehow felt so big when they were young.

At first, the memories sounded simple. Ordinary, even.

But then her voice shifted.

Living in Japan, she explained, changed her in ways she didn’t fully understand at the time.

“Being in a different country when you’re young changes you. It made me more open-minded — more receptive to new experiences and different kinds of people.”

YBS was never just a school building. It was a meeting point of worlds.

American military families. Japanese local families. Different languages, different customs, different ways of thinking — all sharing the same classrooms, the same playground, the same everyday moments.

For a child, that kind of environment becomes normal.

Difference becomes familiar.

Diversity becomes comfortable.

Katie reflected that if she had only attended a school on base, surrounded mostly by students similar to herself, she might have grown up more cautious — maybe even hesitant — about stepping outside her comfort zone.

Instead, she learned early that “different” is not something to fear.

It is something to engage with.

And that quiet confidence — built in small daily interactions years ago — is something she still carries with her today.

That experience matters in her life.


Challenges After Moving Back to the U.S.

Katie moved back to the United States in early 2020 — just as the world was beginning to shut down.

The timing made everything feel even more uncertain.

But even before COVID changed daily life, the cultural shift itself was powerful.

She remembers how different everything felt.

Public spaces felt different.

The atmosphere at school felt different.

Even something as simple as walking somewhere alone — something she had done naturally in Japan — suddenly wasn’t the same.

“In Japan, I could just walk places,” she said. “It felt easier to navigate.”

Back in the U.S., she felt that difference immediately. The rhythm of life. The energy in schools. The way people interacted. It was familiar, yet not.

It would have been easy to shrink back.

But she didn’t.

Instead, she did what she had learned to do years earlier — she kept going.

“School is slow,” she laughed. “You just go every day, and eventually you get used to it.”

There was something simple in that answer. But beneath it was resilience.

At YBS, she had already learned how to move between cultures.

She had learned how to speak up, how to adapt, how to connect with people who were different from her.

She had learned that unfamiliar does not mean impossible.

So when life shifted again, she didn’t panic.

She adjusted.

Day by day. Step by step.

The confidence built in a small international classroom in Japan quietly became the strength that carried her through a global transition.

That is the kind of “living power” education hopes to give —

not just knowledge, but the ability to adapt, to grow, and to keep moving forward when the world changes.

And in Katie’s case, that foundation was already there.


Her Message to Current YBS Students

When asked what she would say to current YBS students, Katie didn’t hesitate.

“YBS is a special opportunity. Make the most of it. Talk to people who are different from you. Engage. Learn from them.”

Simple words — but they carry weight.

Because she has lived the difference.

YBS is not just a school. It is a crossroads of cultures.

Languages overlap. Perspectives collide. Friendships form across backgrounds that might never meet anywhere else.

And when you grow up in that kind of environment, something powerful happens.

You stop being afraid of “different.”

You become curious instead.

Katie believes that daily exposure to multiple cultures doesn’t just make you tolerant — it makes you confident. It gives you perspective. It teaches you how to step into new spaces without shrinking.

That confidence travels with you — into new schools, new countries, new challenges.

Her message isn’t just advice.

It’s proof.

Lean in.

Start conversations.

Be brave enough to connect.

You never know how far those small interactions might carry you.

And that confidence did not stay in the classroom.

It became the quiet engine behind her decisions — the courage to apply to a highly selective academy, the strength to move away from home at sixteen, the resilience to adapt to college-level academics, and the clarity to pursue a future in science.

The confidence she built in a multicultural classroom became the power that now moves her forward.

It allows her to step into new environments without shrinking. To sit in rooms filled with high-achieving peers and still be herself. To choose an accelerated path not out of pressure — but out of purpose.

Most importantly, it gives her the freedom to imagine bigger possibilities.

Confidence does not just help you succeed. It helps you expand.

And in Katie’s case, it has become the foundation for her achievements — and the quiet strength that allows her to thrive, fully and unapologetically, as herself.


A full circle moment

During the conversation between our founder Fumi and Katie, they shared a memory from years ago — riding a Ferris wheel together in Japan. At the time, Fumi was struggling with her business, and little Katie told her:

“When you look at your problems up close, they feel huge. But if you go higher, they look small.”

Katie doesn’t fully remember saying it — but it meant so much.

People of different ages, different nationalities, different roles and perspectives.

When we engage with someone who is “different” from us, our viewpoint shifts.
A view we could not see before suddenly opens up.

That is exactly what happened on that Ferris wheel.

The value of an international school is not just about learning different languages.

It is about sharing space with people of different ages, cultures, and backgrounds, and learning and growing up together beyond the differences.

Time spent in such an environment gently removes invisible limits, expands perspectives, and opens doors to new possibilities.

What Katie taught on that Ferris wheel remains, even today, one of the foundational beliefs of YBS.

 

Now she’s the one going higher.

Academically. Personally. Courageously.

And we couldn’t be more proud.

Katie, YBS will always be your home.

We can’t wait to see how far your curiosity takes you — maybe all the way to the stars.

300 Daikon, Big Courage, One Community!

We were warmly invited by a local farmer, and recently our YBS Preschool children set out for a daikon harvesting adventure.

This time, the children were harvesting Miura Daikon—so big they were nearly the same size as the children themselves!!
As soon as they arrived at the field, energetic voices filled the air:

“うんとこしょUn-tokosho! どっこいしょDokkoisho!”

With their cheerful chants, they took on the giant daikon buried deep in the soil.

Some children tried to pull them out with all their strength on their own.
Others called out, “Let’s do it together!” and worked in pairs.

With hands and faces covered in dirt, they pushed, pulled, and tried again and again.
They looked so determined—like they were standing in front of a giant challenge and declaring, “We’re going to do this!”

At first, the daikon wouldn’t budge.
But little by little… it started to move.

“It’s moving! It’s moving!”

With one final push—pop!—out it came.
Cheers, laughter, and wide-eyed smiles spread across the field.

The sense of accomplishment they felt was far greater than simply pulling out a big vegetable.
They learned the courage to face something difficult, the perseverance to keep trying, and the power of teamwork.

As they pulled the daikon from the earth, they were also pulling out something from within themselves—
their own strength to take on a challenge.

This time, many parents also joined us as volunteers.
We traveled by train and bus—a small journey that became part of the learning.

For our international families especially, the view from the train window was unforgettable.
Soft pink Kawazu cherry blossoms blooming along the tracks, and neatly cultivated fields filled with a variety of vegetables—Japan’s seasonal beauty unfolding before their eyes.

Children gently reminded each other, “We need to be quiet on the train.”

Even the travel time became learning time.
Public manners, seasonal changes, and the rhythm of local life all connected naturally.

By the end of the day, we had harvested more than 300 daikon!!!

Back at school, the harvest was shared with everyone—from the Baby Room to Middle School students, along with parents and staff.

At the entrance, daikon were stacked high.

“I pulled this one out!”
“I got a really heavy one!”

The pride on their faces was impossible to hide.
The feeling of the soil, the moment of struggle, the joy of success—those memories were already part of them.

Those 300 giant daikon did more than fill our school entrance.
They brought together local farmers, families, children, and staff as one community.

It was not just a harvesting trip.
It was a day created together—through support, cooperation, and shared experience.

And within that day, children discovered courage, teamwork, and gratitude toward the community that supports them.

We truly believe that the confidence and thankful hearts nurtured through this experience will continue to support their learning and growth in the years ahead.

A Warm Gift, A Great Inspiration — Growing Together with Our Community

With the heartfelt vision of supporting children’s development in the community and encouraging diverse learning opportunities, Sumitomo Mitsui Trust Bank, Limited generously donated a basketball hoop and basketballs to YBS.

Sumitomo Mitsui Trust Bank values sustainable growth, community partnership, and investing in future generations.
This donation reflects those values in action — a meaningful support in our children and their future.

Children were invited to take part in the donation ceremony held the other day.
Standing in front of the brand-new hoop and the cool new basketballs, their smiles said it all!

As representatives handed each child a ball and stickers, excited voices filled the space:
“Can we use it now?” “Do we get to play basketball today?”
Seeing the children hold their new basketballs so carefully and proudly created a heartwarming atmosphere for everyone present.

At YBS, we value learning and growth in a bilingual environment immersed in both the Japanese way and the global way.
Within that journey, sports serve as a universal language that connects hearts beyond words and cultures.

It is not only about winning or losing.
It is about taking on challenges with passion, supporting teammates, and building confidence through achievement. These experiences become powerful tools that support children’s continued learning and personal growth.

This donation reminded us of something very important:

Our children are not growing up alone within school walls.
They are surrounded by adults, companies, and community members who genuinely believe in them and want to see them thrive.

YBS is a school supported by many caring hands and hopeful hearts.

When children know they are valued by their community, they grow with confidence.
They learn to take on challenges, support one another, and believe in their own potential.

We are truly grateful to be part of a community where businesses and individuals stand behind our learners.

With deep gratitude for the support of our community, we will continue expanding opportunities and possibilities for our young learners.
