Horizon Japan International School is an IB (International Baccalaureate) World School, authorized to offer the PYP, MYP, and DP Programmes. IB World Schools share a common philosophy – a commitment to a high quality, challenging, international education that HJIS believes is important for our students. 

Growing Through Meaningful Choices

At HJIS, we teach students to become more independent as they explore the world on their own and discover how to express themselves. They also begin to understand how their choices and actions influence outcomes. It is obvious that making meaningful choices is an essential part of children’s cognitive development and personal confidence, which grows as they think through choices that are presented to them.
