Our Preschool Program
PROGRAM OVERVIEW
Our full-time Forest School offers a one-of-a-kind, nature-based learning experience that aligns with an international school calendar. Throughout the year, children embark on exciting outdoor adventures 2-3 times a week, where they explore, discover, and connect with nature in meaningful ways. The entire school year is thoughtfully designed to follow the rhythm of the changing seasons, allowing children to fully immerse themselves in the wonders of the natural world. From scavenging for insects and foraging for wild fruits to building friendships and socializing in nature’s classroom, every moment is an opportunity for growth, discovery, and joy.

Q: Did you feel involved and well-informed about your child's experiences? What instances can you think of that were informative or needed more work?
Everything fell within my expectations. The only thing that surprised me in a positive way was that three years old started using a knife.

Callie
Q: What were your thoughts on the overall vibe and atmosphere of iForest? Did it align with what you were expecting?
A:“100%. Absolutely the most wonderful experience I could give my children. It was exactly what I had hoped for. I love that they truly go into the wilderness rather than just spending outdoor time at a playground. They have so much time and space to dig into their curiosity, and freedom to find their own path and itinerary throughout the day. What a gift.“

Eito
Q: What values (if any) do you think this kind of education has to offer?
A: There is a lot we can learn from nature which is limited when one learns only in an indoor environment. In order to preserve the delicate ecosystem, it’s crucial to start young to be respectful of nature and its surroundings. A small impact leads to ripples of aftermath, no matter how small or insignificant we think that small action may be.

Our Retreat Program
PROGRAM OVERVIEW
We know how important it is for kids to connect with nature and the busy lifestyle of the concrete jungle. Let the children feel the earth beneath their feet and the wind in their hair. That’s why we’ve created a space where little ones can truly immerse themselves in the wonders of the forest. iForest principals are about fostering a deep, holistic relationship with the natural world. From muddy puddles to bird songs, every moment is an opportunity for discovery and growth. iForest retreat is based on our Preschool program, a place where children can learn, explore, and connect with nature in a meaningful way.

Kai Chang
Founder
At iForest, nature is the classroom—and the greatest teacher. We protect childhood by giving children the freedom to play, explore, take age-appropriate risks, and develop at their own pace. Through early, meaningful relationships with nature, children develop a deep sense of belonging—and grow into adults who care for and protect the world they love.
In today’s world, children are being pushed to become “school ready” before they are developmentally ready. Academics are introduced earlier and earlier, often at the cost of movement, play, and exploration. Yet early childhood is the only time in life when children are meant to simply be children.
Children learn best when they feel safe, have time, and are free to move their bodies. Running, climbing, jumping, and taking manageable risks are not distractions from learning, which are essential to healthy physical, emotional, and social development. Inside traditional classrooms, these experiences are often limited.
Nature offers what classrooms cannot. In natural environments, children move freely, test their abilities, solve real problems, and learn through direct experience. Uneven ground builds balance. Weather builds resilience. Open space invites curiosity, confidence, and creativity. Learning becomes active, meaningful, and deeply engaging.

Hisami Muramatsu
Head Facilitator
I have worked with children for over 20 years, they have always helped me with my interpersonal growth. In my time working in Tokyo international schools, I have always been interested in education in nature, which I could not experience in an urban school life. Born and raised in the countryside of Shizuoka, I have first hand experience that there is so much to learn being surrounded by nature. The ability to notice, feel, and enjoy it is a very important part of early childhood education.
The time spent using all five senses, interacting with the earth, the sun, the sea, rivers, plants, and animals, thinking and acting for oneself, and deepening the experience will become an irreplaceable asset. The ability to act on one’s own interests and thoughts, rather than just following instructions given to them, is essential for development.
My goal is to provide an environment that allows children to develop their sensitivity, adventurous spirit, and sense of interest, which grow dramatically during their early childhood years. Not only children, but adults as well need to be thrilled and excited.
Let’s play with the earth together in our forest playground with unlimited possibilities.

Samantha Leahy
artForest Facilitator
Hi, I'm Samantha. I am an educator and freelance artist with a Bachelor's degree in Early Childhood Education. I have worked as an educator in both Australia and Japan, in preschool settings as well as nature education programs, including outdoor and camp-based experiences.
ArtForest combines nature education and outdoor exploration with open-ended art projects. This course focuses on creating opportunities for children to freely explore materials, respond to their natural surroundings, and approach art in an open and flexible way. Using natural and found materials encourages creativity and experimentation, while also allowing children to learn about nature through the process of making and creating.
Alongside my work as an educator, I studied picture book art at Vantan Design Institute in Japan and continue to work as an illustrator and artist. I create artwork in a variety of mediums, including watercolour, pastel, and digital illustration. I work as a freelance artist in Japan and also sell my work through international companies, such as poster and T-shirt companies.
