One World International School Tokyo


Welcome to One World International School


With an emphasis on balance, autonomy and international diversity, our school is designed to provide students with a well-rounded learning experience that ensures their success as adults.


Why choose One World International School?


At OWIS Tokyo, we offer students an individualised approach to the learning process and we introduce them to the rigorous, international curricula that they need to grow and succeed. Families benefit from a high-quality education at a mindful investment, with no compromises when it comes to helping their child become the best version of themselves.

Remarkable Global Student Community

Our extraordinary community is one of the things that makes OWIS such an amazing place for students to learn, grow and develop into future global citizens. Each member of our community not only contributes to the vibrancy of our community, but in doing so supports a remarkably synergistic effect. Together, we are greater than the sum of our parts.

What Our OWIS Singapore Families Are Saying

All our 5 children are now attending OWIS Singapore since January 2018. 

I would recommend the school to other families who are looking for innovative teaching methods and the use of technology, and mindfully integrating learning with the gadget-driven world of today.

Being in Singapore, which is so multi-racial and multi-cultural, we wanted our children to be exposed to an environment with racial diversity with an international outlook. OWIS has lived up to all our expectations!

Our daughters (aged 5 and 7) have been enrolled at OWIS for 10 months, having moved to Singapore from Japan. Both our girls are very fond of their teachers and are always keen to go to school each day. We have seen significant improvements from their time with the school, especially in terms of reading and writing. Further, we have noted that the teachers take time to get to know each student at an individual level; putting significant effort into building the children’s social skills, and encouraging them to solve problems on their own.

Chanya was 6 years old when she enrolled grade 1 during the academic year in October 2016. She was previously in a Thai school and we realized that her English language ability would obstruct her school daily life. As a new student, both to the school and in language communication, I was so worried for her. But after starting at the One World International School, my daughter had settled down very well after the first few weeks. The English as an Additional Language program (EAL) offering one-on-one has helped her to catch up quickly with her social life and normal classes.We have been very delighted being a part of the “One World” community.

Being in One World International School has provided such a positive experience for my son and our family. As an expat child, it is unfortunately easy to feel like you don't belong. This is not the case with OWIS. The OWIS family embraced us with open arms and my son immediately felt included. I remember the first thing my son told me when he started with OWIS. He said, "I feel like I have been going to this school for a long time! I love it here!" He is excited to go to school every day ever since!

The OWIS Learning Model


OWIS is not the only educational institution in the region that offers an inviting and exciting international curriculum, but there aren't many other places where you will find the emphasis to be on the needs of your individual student. Through frequent communication and strategies that allow us to personalise the curriculum for your individual learner, we have created a place where passion and success go hand-in-hand.
