A class for every stage of childhood
Treehouse offers engaging Montessori programmes for children from 12 months to 9 years — from first steps into the classroom to preparing for primary school.


























Ladybug Class
てんとうむしクラスThe Ladybug programme helps young children make the transition from the parents' nest to the outside world. Children are given plenty of one-on-one time with the teaching staff, while being encouraged to become independent and self-sufficient in the classroom.
All activities are conducted with materials scaled to the children's size and ability, developing hand-eye coordination and confidence. The ability to choose their own activity encourages free will and creative thinking from an early age.

Bluebird Class
あおいとりクラスAt the Bluebird level, academic studies and deeper social immersion are introduced. The programme builds on the Montessori foundation to prepare children fully for first grade and beyond.
The classroom is outfitted with child-sized tables and chairs, with materials designed to develop curiosity across a broad spectrum — from practical skills to mathematics, language, music, and culture.
Unlike traditional education, Montessori children choose from well-planned options and follow their own interests — fostering inner motivation, discipline and independence.

Summer Programme
サマープログラムThe Treehouse Summer Programme has been one of our most popular courses since opening in 2001. Children enjoy the giant pool in our backyard, while water play and smaller pools are available out front.
The programme runs on weekly themes that shape the week's activities — including cooking, arts and crafts, and plenty of outdoor play.
