Start Your Child’s English Success Story With OWIS
“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.”
“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.”
Thanks to the teachers, we truly feel that enrolling in this school was the right decision. The UOI and presentation-based learning, which cannot be experienced in Japanese schools, are especially valuable. In addition, interacting with children from different countries every day provides positive stimulation and helps broaden his perspective, allowing him to absorb a wide range of ways of thinking.
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!
After attending OWIS Osaka for a year, he has become more self-motivated in both soccer and academics. The teachers are highly qualified, and it's great that he can receive overseas-style education while living in Japan.
As parents, we truly value OWIS’s holistic education approach built around the IB philosophy. Through inquiry-based learning, the school connects knowledge with the real world, helping children develop critical thinking, problem-solving skills, and social-emotional growth. The teachers are both professional and caring, with a strong focus on personalised support. The diverse international environment also helps children strengthen their language skills and learn to understand different cultures with an open and inclusive mindset, building a strong foundation for the future.
I chose this school not only because it offers an educational environment where students can thoroughly develop their English skills, but also because I sensed a school culture that values freedom and respects students’ independence.
Although it’s a newly established school, the teachers are very responsible and place great emphasis on academics. With homework and monthly tests, we’ve seen clear progress in our child. In addition, the extracurricular activities are rich and diverse. At our school’s Spring Carnival in March, there were all kinds of delicious food, games, small animals, and industry experts celebrating together with teachers, students, and parents. It was absolutely delightful! Even a month later, our child still can’t stop talking about it.
We chose OWIS to teach our daughter both English and Japanese. Your school came highly recommended for our education journey. We wanted and encouraged a hybrid education as our daughter will also go to school in the US. Thank you so much for including us!
My child has been studying in an English-language environment at other international schools since kindergarten. Although my child briefly attended a public elementary school, he or she was determined to continue learning in an English-language environment. After doing a lot of research, we discovered OWIS. We chose OWIS because of its curriculum, which stimulates children’s curiosity, and its comprehensive support system. We also felt that the newly built outdoor facilities would provide plenty of opportunities for physical activity.
We came across OWIS while searching online and decided to choose it because we felt that the curriculum was strong and the teachers friendly and reliable. Our child is also looking forward to starting in a new enviroment while attending this school.
You guys ROCK! Thank you so much for supporting Food Bank Kansai and spreading the word.

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.
