See What Parents Have to Say About Our Campus
“I really like the teachers here, they are always smiling and are really kind, and it's great to see that they hold a lot of our family’s values. My kids also seem to really enjoy their teacher’s mentorship style. My children have started the PYP curriculum and are learning lots of things that I wish I had learned as a kid. My child loves the gardening classes, the school pet and anything to do with nature. We love to see that the education is very tangible and hands-on.”
Jeremy Carlson
Parent of Students in Early Childhood and Primary School“OWIS’s legacy and big brand presence were a focal point for us. Our son has really enjoyed the strong exposure to science, and today, I saw his presentation on economics. He knows so much more about economics than even I do, and he is just 10 years old!“
Rahul Kaushik
Parent of Students in Early Childhood and Primary School“Each day we have been greeted by teachers with warm smiles and genuine kindness - this left a deep impression on us. What touched us even more is how many teachers already remembered my son Eric & Ethan's names. Their homeroom teacher, Ms Mariko & Ms Michelle, have offered consistent encouragement and recognition, which has deeply reassured both our children and us as parents. We truly believe th111ey will continue to thrive with this kind of support”
Arrow Xia
Parent of Students in Early Childhood and Primary School“You guys ROCK! Thank you so much for supporting Food Bank Kansai and spreading the word.”

We’re excited to officially unveil the latest update to our brand-new yard and outdoor facilities! 🎉
ついに、新しいフィールドと屋外設備は完成しました！🎉✨

This new environment has also allowed many of our PE classes to move outside, opening up a whole new world of opportunities for active learning, exploration, and play. 🥅
==========
工事が完了し、完成したばかりの空間には、すでに生徒たちの元気な笑い声とエネルギーがあふれています。
休み時間になると、友達と一緒に思いきり走り回り、のびのびと楽しむ姿が見られます。
この新しい環境は、プロコーチ陣の指導や競技チーム「Blue Royals 」の活動を通して、
スポーツに力を入れるインターナショナルスクールとして、さらに大きな一歩を踏み出すものです。
また、屋外スペースの充実により、PEクラスを外で実施できるようになりました。
よりアクティブな学びや探究、そして仲間と協力する経験の幅が広がっています。🥅🌿

This is one of the most important messages we teach our students at OWIS.
As part of this special day, our students have once again shown kindness by taking part in pink-shirt day - an event of compassion and love to others, symbolized by wearing the color pink. 💕
We also had an pink angel wing photo booth set up for them which they made good use of! 📸✨

これは、OWISで私たちが生徒たちに伝えている、とても大切なメッセージのひとつです。

Our youngest students have surprised us with a theatrical and musical performance! 🎭🎶
子どもたちは、プレイや演奏で私たちを驚かせてくれました！🎭🎶
Together with their teachers, they worked hard on creating their own props and costumes for “Little Red Riding Hood”, which they then performed in both the English and Japanese versions! ✨
Meanwhile, some of their classmates prepared a fun, energetic song to sing to their friends - they even played some instruments! A nice and fun time for everyone involved! 😊

Time for science!
科学の時間です！
As part of science class, our students conducted an experiment where they tested various foods, drinks and items for their pH values. A pH value is a number that measures how acidic or basic (alkaline) something is. 🧪
Under supervision of their teachers, the students recorded their findings in groups and then presented them to the rest of the class. A fun and interesting activity that everyone was able to take something away from!
-------------------------------------------------------------------------------
科学の授業の一環として、生徒たちは学校にあるさまざまな物の pH値 を調べる実験に挑戦しました！pHは、水溶液が酸性かアルカリ性かを示す大切な指標です🧪
先生の監督のもと、生徒たちが結果を記録し、クラスの前で発表しました。発見がいっぱいで、学びと楽しさが詰まった活動となりました！

Our Grade 3 students designed and built Future Cities and Space Cities, exploring the IB Unit of Inquiry “How the World Works.”
3年生の児童は 「世界の仕組み」の一環として、未来の街と宇宙の街を設計・制作しました。
Working in teams, they researched how cities function on Earth—and imagined how they might work in space—while exploring energy, sustainability, transportation, gravity, and life-support systems. Using the engineering design process, students planned, created, tested, improved, and proudly presented their models to peers and families.
This project fostered curiosity, creativity, collaboration, and critical thinking, helping students connect science to real-world and future-world challenges 🌍✨
-------------------------------------------------------------------------------
チームで街の仕組みを探究し、それが宇宙ではどのように機能するのかを想像しました。さらに、エネルギー・持続可能性・交通・重力・生命維持システムについても学びました。
模型を作り、試し、改善し、最後に家族や友達に発表しました！
このプロジェクトを通して、未来に向けた好奇心、創造力、協働する力を育みました。🌍✨
