“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.”

“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!“

“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 they will continue to thrive with this kind of support.”

“You guys ROCK! Thank you so much for supporting Food Bank Kansai and spreading the word.”

Rather than following a rigid framework, our approach emphasises concept development across subject areas to make learning relevant and meaningful beyond the classroom.
By exploring global perspectives and real-world challenges, we empower students to become responsible global citizens who contribute positively to an interconnected world.
Through inquiry-based and student-centred learning, we inspire curiosity, critical thinking, and a lifelong love of learning.
By working together on weekly collaborative projects across cultures and perspectives, students develop empathy, communication skills, and the ability to contribute meaningfully to shared goals.
Through meaningful contributions to charitable initiatives, the school community, and the local neighbourhood, we encourage students to become aware of the needs around them and to respond with empathy and action.
Through strong relationships built on respect, trust, and empathy, we create a supportive community where every student feels valued and empowered to thrive.
Resilience, open-mindedness, humility, and self-belief form the foundation of our character development, empowering students to thrive and make a positive impact on the world around them.
