Where Little Learners Grow to be Themselves
We're a small, independent Montessori school tucked into a warm, cozy house in Honmoku, Yokohama — welcoming children from 12 months to 6 years old. Our tight-knit team creates a home-like environment where every child feels safe, seen, and free to grow.

A place where every child feels at home
Small by design, warm by nature. We've been nurturing children in Honmoku since 2001 — because we believe the best learning happens when children feel safe, seen, and free to be themselves.
2001年の開校以来、横浜・本牧で子どもたちの成長を見守ってきました。安心して自分らしくいられる環境こそが、最高の学びの場だと信じています。
Learn more about us →Every child gets the individual attention they deserve. Our small classes mean teachers truly know each child — their strengths, their pace, their personality.
Our curriculum follows the Montessori Method of Education — encouraging independence, curiosity, and self-directed learning from the very first day.
English is our language of instruction, but we celebrate every language and culture — reflecting the rich international community of Yokohama.
We're not a big institution — we're a cozy house in a quiet neighbourhood. Children arrive to familiar faces, warm spaces, and a community that feels like family.
