Welcome to Tokyo West International School. It is with great honor that I welcome you to one of the most dynamic, exciting international schools in Japan.

We, Tokyo West International School, are a boutique school located in Hachioji, Tokyo. We believe our students grow locally within the vast and sumptuous surroundings of nature and soar globally with a balanced education they will have obtained at Tokyo West International School. Our teachers and staff at Tokyo West International School hold our core values front and center all times. We are deeply committed to creating a physically and psychologically safe environment where each student can challenge themselves to succeed, fail, learn, and grow.

In this century, the education that will serve our students well in their lives is quite different from that of their parent’s generation. Our students will live and work symbiotically with AI, as just one example. The issues and challenges the next generation faces are, in some respects, more complicated than what we have seen before at the same time in other respects resemble challenges previous generations have faced in times of significant change.

For these reasons, we strive to provide education that includes both new ways of thinking and learning and as well as the core fundamental experiences and skills that will guide our students to succeed in their future. Our hands-on education inspires students to learn by doing.

Specifically, we offer these five unique programs to our students:

  • The Young Americans Musical Theater Program
  • Bilingual Education Program
  • Singapore Math Program
  • Travel and Learn Program
  • Organic Garden Program

Through these programs and the daily general education we offer, students experience multi-faceted learning that engages their intellectual, emotional, and physical aspects of themselves.

Our talented and dedicated faculty brings these experiences to life for our students. I could not be prouder of our diverse and dedicated faculty and staff member on board. They practice what student-centered means every day and motivate our students to learn by caring. Our teachers are students’ mentors, students’ guides, and sometimes facilitators. They empower students to appreciate the sharing of different cultures and values.

Tokyo West International School is ever-evolving, symbolized by our revised motto and vision. There is still much room to grow, and such growth should be built on a solid foundation of trust among all members of our community, including students, parents, teachers, and staff. We welcome you to join our community and become a part of the educational journey of your child at Tokyo West International School.

To this end, I wish to invite you to visit our campus and facilities to discover our philosophy in action, how we are fostering our students to grow locally and soar globally. I am looking forward to meeting you in person on campus grounds to begin our successful partnership in your child’s future education, growth, and development.
