A new location, with a new name.
The school has relocated from Tokyo Tower and has been renamed CASA ATLAS Montessori School. In our new environment, we will continue to provide a Montessori education that supports each child’s growth with the same care and commitment as before.

Casa Atlas Montessori School

We are pleased to share that our school will be renamed CASA ATLAS Montessori School as we prepare to transition to our new location. This name reflects our identity and the vibrant, diverse community we have built together. It represents a warm, childcentered Montessori environment where children explore the world, cultivate independence, and grow as confident global citizens. The spirit of the name is international, welcoming, and purposedriven—perfectly aligned with our multicultural Montessori community.

We chose this name to honor the diversity of our families, to express our Montessori philosophy clearly, and to highlight our international perspective.

Although our name is changing, our mission remains the same. We will continue to provide a nurturing Montessori environment where independence, kindness, and joyful learning thrive.

Renewal of Class Structure

As part of our fresh start, we will also be updating our class names.

  •  The Bumblebee Class will become the Mini Atlas Class.
  •  The Ladybug Class will become the Sunny Atlas Class.
  • The Butterfly G1 will transition to the Star Atlas Class.
  • The Butterfly G2 will be renamed the Sky Atlas Class.

Thank you for your continued trust and partnership. We look forward to beginning this exciting new chapter together as CASA ATLAS Montessori School.

Details regarding class structure are currently being reviewed. Updates will be shared with parents and announced on our website as they become available. Thank you for your patience.

Why Montessori Education?

Internationally recognized

Montessori has been flourishing around the globe and has countless graduates who have become internationally recognized. From Jeff Bezos, Larry Page & Sergei Brin (founders of Google), Prince William, Prince Harry, Thomas Edison, George Clooney, Yo Yo Ma, U.S. President Woodrow Wilson, Taylor Swift, Fuji Sota, and many more!

“Montessori helped me become the person I am today”.
STEPHEN CURRY, NBA MVP AND A MONTESSORI ALUM (PRESCHOOL – GRADE 6)

All parents recognize the importance and lasting impact early childhood education has on a child’s development, future, and way of thinking. Ages 0-6 are a critical time which sets a strong foundation for a child. In Montessori we guide children to have a strong sense of self, learn to connect with others, and discover the environment which surrounds them.

“We both went to Montessori school, and I think it was part of that training … of being self-motivated, questioning what’s going on in the world, doing things a little bit different. – Larry Page – CEO, Co-Founder of Google

Classroom Environment

A Montessori classroom is thoughtfully designed to offer children opportunities to grow to their greatest potential, whether it is learning how to dress themselves independently, multiply and divide a multi-digit equation, communicate their thoughts and feelings effectively, or problem solve with others. Each classroom is filled with developmentally appropriate activities that sparks a child’s interest through its beauty and complexity.

In a Montessori classroom, teachers assess each individual student daily, using these observations teachers will guide and teach students new lessons and materials. Teachers recognize these moments of interest and moments a child is absorbing knowledge and ensure that they are exposed to the full sequence of lessons in each area while providing support and new challenges as needed.

“I really like Montessori and all my children have (or will, in the case of the baby) gone to Montessori preschools”
⁃ Jimmy Wales (Founder of Wikipedia)

“I do not believe there is a method better than Montessori for making children sensitive to the beauties of the world and awakening their curiosity regarding the secrets of life.”
Gabriel Garcia Marquez – Nobel Prize Winner for Literature.

An authentic Montessori curriculum in harmony with Dr. Maria Montessori's philosophies.

“I discovered that children learn naturally through activity, and that their characters develop through freedom. But these are general principles, which require practical application, and the Montessori materials have been evolved to meet this need.” – Maria Montessori

All classes are taught in English and are guided by teachers who hold Montessori diplomas.

The greatest strength of a Montessori education is its respect towards each child and its support to help every child grow to their greatest potential.

Montessori education backed by over thirty years of experience.
