15-18 Adolescent Program
Beyond Preparation, Into Life Itself
Rooted in Tokyo's international community, adolescents engage in meaningful work through internships, entrepreneurial ventures, and community partnerships. They discover their purpose by testing themselves against genuine challenges, developing the clarity of vision needed to shape the future of human society.
This is Montessori's vision for adolescence, fully realized: an education where students become confident communicators, culturally responsive global citizens, resilient problem-solvers, and passionate change agents ready to bridge differences with compassion and pursue work that serves the greater world.
What is a Montessori High School?
We believe that to shape the future, adolescents must actively participate in the present. Our 15-18 Adolescent Program responds to the two needs of adolescents: Protection during their transition from childhood to adulthood and a rich understanding of the society they are about to enter. Students spend their days engaging in interdisciplinary projects, running small businesses, and engaging in internships across Tokyo; all while honing their passions and purpose.
What’s most important is that all learning is designed to impact the world in a positive way. Our focus isn’t on memorization of knowledge, but meaningful application of it.
