Dear Students, Parents, Guardians, and Friends.

My warmest greetings to you all as I welcome you to Tokyo West International School – one of the most diverse, vigorous, and flourishing international schools in Japan.

We are a close-knit school community with very supportive parents, dedicated teachers, and wonderful students. We celebrate our diversity and create a culture of belonging where everyone feels welcome, valued, and respected.

What makes TWIS unique?
Aside from being the first Cognia-accredited school in Japan, we pride ourselves on the following achievements and programs for our students:

  • Organic Garden
  • Bilingual Education
  • Singapore Math
  • Travel and Learn
  • The Heart Global Musical Theater

What is our aim for our learners?
At Tokyo West International School, we believe that each and every individual has unique talents, interests, dreams, and aspirations waiting to be discovered and nurtured. As an authorized IB PYP school, we “aim to develop inquiring, knowledgeable, and caring young people who help to create a better and more peaceful world through intercultural understanding and respect” (IBO, 2024). We are committed to providing a safe, supportive, and inclusive environment where students learn and grow.

Our motto is Grow Local, Soar Global. Through the quality of education that we provide, we “nurture our students’ growth and passions with locally relevant hands-on education that crosses cultural, digital, and analog boundaries. We help our students develop a strong sense of self and curiosity to soar to greater heights and possibilities as global citizens.”

This year, we are getting ready for our upcoming Cognia re-accreditation. We also have started our preparations for the PYP evaluation. With the help of all our stakeholders and their continuous support, we would be able to take our school to the highest level of excellence.

I would like to invite you to explore our website and visit our school to learn more about our programs, activities, and events. Feel free to reach out if you have any questions or need assistance. We would be very happy to help you!

Warmest regards,

Monina Mendez
Deputy Principal

Tokyo West is a great place to study. Our fully equipped Hachioji campus was completed in 2015. It has been built according to the most advanced safety standards. From the windows of our bright classrooms, the students can enjoy the changing of the seasons and the view of the surrounding greenery.

We operate a school bus in the Tama area. There is also a school nurse, so you can feel safe.
