About us


IntroductionOur mission at Tokyo West International School (TWIS) is to equip children with the skills they need to become successful leaders in our constantly evolving, globalized society. We strongly believe in the importance for young people to be able to think independently, solve problems, be proactive, and be mentally flexible. We promote the values of sensiti3ity, international mindedness, being appreciative of cultural differences, as well as the importance of a healthy and active lifestyle. We are convinced that the balanced development of a child’s academic, social and physical skills is the key for them to be able to actively shape their future.

Our school provides a wide variety of academic lessons, activities and events stimulating our students’ intellect and nurturing their communication and social skills. In our encouraging and supportive environment, children are given room to grow and cultivate their talents, respecting each student’s strengths and personality. Experiencing challenges and the joy of succeeding will stimulate the children’s young minds and prepare them to become confident, contributing members of society.

We welcome you to browse through our website, and we look forward to meeting you and your child soon at TWIS.

Our Slogan: LEAD

Making dreams come true

Dreams motivate people to give their best. Turning dreams into reality requires effort and commitment, there might be many obstacles lying ahead, but it is facing these challenges that make us grow stronger. Some dreams will change, while others will last for a lifetime. Having dreams to follow is the first step towards a life of fulfillment.

At TWIS, we are convinced that the role of the school is to give children the tools to make their dreams come true. Experiencing the joy of achievement as well as the frustration of failure, the determination to challenge themselves over and over again and the satisfaction of succeeding are integral to the educational experience. These experiences will become the critical foundation that our students will build upon.

Our school’s philosophy is encompassed by the slogan: LEAD.
