About Treehouse
A small, warm Montessori school in the heart of Honmoku — founded on the belief that every child has the capacity to learn, grow, and flourish in their own way.
"Every child deserves to feel seen, safe, and free to grow at their own pace."
Jenny Vyvial — Founder & Head of SchoolJenny has been working with and caring for children for more than 20 years. She was drawn to the Montessori method because it works from the core of each child — allowing them to explore, learn and grow as a unique individual rather than following a one-size-fits-all curriculum.
Certified as a Montessori teacher in 2000, Jenny opened Treehouse the following year — bringing the first intimate, hands-on Montessori experience to the Yokohama area. More than two decades on, she remains as passionate as ever about creating an environment where every child feels truly seen.

Learning that follows the child
Montessori education is built on a simple but powerful idea — that children have a natural desire to learn, and that the best thing we can do is create the right environment for that learning to happen.
Rather than filling children with facts from a fixed curriculum, Montessori encourages them to follow their own curiosity. Children choose their own activities, work at their own pace, and learn through doing — using hands-on materials that make abstract ideas tangible and real.
The result is children who are not just knowledgeable, but genuinely motivated — children who love to learn because learning has always felt like their own idea.
モンテッソーリ教育の根本は、子どもたちが本来持つ「学びたい」という意欲を大切にすることです。子ども自身の好奇心に従いながら、自分のペースで学んでいきます。
Five areas of learning
Every Treehouse classroom is thoughtfully prepared across five core areas — each designed to nurture a different dimension of your child's development.
Everyday tasks like pouring, buttoning and sweeping — building coordination, concentration and independence through real-world activities.
Materials that engage sight, touch, sound, taste and smell — refining the senses and laying the groundwork for reading and writing.
Sandpaper letters and movable alphabets guide children naturally toward reading, writing and rich communication.
Concrete materials that make numbers feel real — children count and compare long before abstract maths makes sense on paper.
Geography, science, botany and the arts — helping children feel connected to the world around them.
