Leveraging the benefits of being a non-article 1 school, we base our curriculum on the International Baccalaureate (IB) while also incorporating elements from Japan’s course of study and other international curriculum flexibly.
With an April enrollment and the requirement that parents speak either English or Japanese, CGK is an accessible international school for many families.
Building on the foundation established in our preschool, the IB Primary Years Programme (PYP) continues into our elementary school. We further deepen inquiry at a higher level using a transdisciplinary approach that transcends traditional subject boundaries.
This type of learning is highly practical and well-suited for young learners as they engage with society and the world around them.
To enhance their inquiry and understanding, we also actively incorporate field trips and other experiential learning opportunities.
In our daily 45-minute Japanese classes, we focus on developing students’ self-expression, critical thinking skills, and a spirit of inquiry in a balanced manner, reflecting our commitment to nurturing lifelong learners who thrive in multiple languages. We believe that supporting a child’s native language and the language of their country of residence is crucial for deepening their cultural identity and promoting cognitive, social, and emotional development.
Accordingly, we place a strong emphasis on Japanese language education (JLL/Japanese Language and Literature) based on the curriculum standards from the MEXT while also dedicating significant resources to Japanese language classes for students learning it as a foreign language (JAL/Japanese as an Acquisition Language).
*All subjects except Japanese are taught in English.
We offer overseas study programs to encourage children to become self-reliant, self-directed and lifelong learners. Our staff will help you make the arrangements after finding out the needs of your child and your family. There are many different options to study abroad, for example, parent-child study abroad, home-stay, and boarding schools. These are very valuable opportunities to put learning to practical use in a new environment, apart from the daily life at CGK, and parents will be touched to see how much their children grow.
CGK strongly recommends studying abroad at a young age, as it provides an opportunity to experience an unknown world and gain exposure to diverse values and ways of thinking, which in turn, leads to growth.
Also, CGK is a welcoming place for international students from abroad with a view to encouraging multicultural cooperation.
We offer After Care (until 4pm), Club Activities (until 4:30pm), and Afterschool (until 7pm).
Students can participate in a wide range of activities, from cultural and athletic pursuits to relaxation time and in-depth exploration of various subjects.

“It feels like autumn.” What colours, sounds or sensations are held in that small observation? Finding words for a season is not only about using vocabulary we already know. It is also a way of discovering what we have noticed.
In Japanese language learning at CGK Elementary School (Grades 1-5), students explore seasonal words and changes in nature through haiku and free verse. The aim is not simply to produce a polished poem straight away. The process of searching for words that fit an observation or feeling, and choosing how to express it, matters too.
Imagine looking at a leaf and calling it beautiful. Rather than stopping there, look a little longer. Which colours overlap? What changes when light passes through it? What sound do leaves make underfoot? More specific observations give us more possibilities for expression.
Two children may notice different things in the same scene. One might focus on colour; another on sound or texture. Instead of offering the “right” description first, an adult can ask, “What did you notice that made you feel that way?” and listen to the child`s perspective.
At home, this could be as simple as choosing one interesting thing during a walk and looking for words to describe it. There is no need to turn it into a formal haiku. A short sentence is enough.
Expression becomes interesting where a growing vocabulary meets a child`s own way of seeing. Both deserve room to develop.
At CGK Elementary School, mathematics and Japanese language are taught through Units of Inquiry (UOI) wherever possible. When lessons focused on particular skills are more appropriate, subject content is also taught separately.
To explore a question in depth, children need to read for meaning, work with numbers and quantities, and put their thinking into words. Using those skills to investigate a question also helps them see why the skills matter. Foundations support inquiry; inquiry gives those foundations a purpose.
At CGK Elementary School (Grades 1-5), we connect subjects where meaningful while making time to develop individual skills carefully.
Consider a comparison. A child might initially feel that one quantity is greater than another. Using numbers or measurements to check that impression, then explaining the evidence, makes the comparison more precise. This is one example of mathematics and language becoming tools for thinking.
Leaving room for children to think does not mean withholding the knowledge or methods they need. There is a place for demonstrating a method, a place for practising it, and a place for children to decide how to apply it. Each has a role in supporting inquiry.
We do not have to choose between independent thinking and strong foundations. What matters is helping children move between the two.

A little water on a hand. A small step into something new. 💧
Ocean Class (2-year-olds) tried its first water play at the end of July, as featured in August`s CGK Times.
Some children began cautiously, pouring small amounts from cups onto hands and feet. As they grew more comfortable, they explored spray bottles, water guns and toys that floated or sank.
Popular water guns also brought a social challenge: there were not enough for everyone at once. Children asked to use them, waited and passed them on. Sometimes waiting was frustrating too.
The story holds both enjoyment and difficulty. Exploring something new includes learning about our own feelings and those of our friends.

手に少し、水をかけてみる。新しい遊びへの、小さな一歩。💧
CGK Times 8月号では、Oceanクラス(2歳児)が7月末に初めて楽しんだ水遊びを紹介しています。
The machine was finished. The explanation mattered too.
At the end of CGK Afterschool`s two-day hydraulic and pneumatic machine project, teams demonstrated their creations and explained their choices and difficulties.
One team`s challenge was improving how well its machine could lift. In its presentation, the team described overcoming that obstacle through communication, teamwork and repeated testing—and by not giving up.
A working model shows one outcome. Explaining the changes and challenges reveals more of the learning behind it.
The project was part of Summer School, featured in August`s CGK Times. CGK Afterschool programme: Grades 1–9.

Show & Tell does not end when the speaker finishes.
In Mountain B Class (4-year-olds), children regularly share something meaningful to them: a favourite object, an interest or a personal experience.
Then it is their friends` turn—not simply to wait, but to listen, decide what they want to know and put a question into words.
Teachers have noticed children becoming more comfortable sharing their ideas with the group. The repeated opportunities matter: speaking, listening and asking are all part of participating in a classroom community.
One object can open many conversations.

In a two-day Summer School project at CGK Afterschool, teams built hydraulic and pneumatic machines.
Teachers provided instructions for the base. From there, students made their own adjustments through a cycle of design → build → test → improve, keeping one function in mind: lifting different materials.
There was something concrete to test—not just whether a model looked finished, but what it could do. Each round gave teams another opportunity to consider a change.
The finished machine is only part of the story. The decisions made along the way matter too.

A campsite indoors. Real opportunities to share. ⛺
When summer heat limited time outside, our teachers brought Jungle A and B Classes (3-year-olds) together for an indoor camping adventure.
Children caught pretend fish, cooked on a DIY barbecue and roasted cotton-ball marshmallows over a pretend fire. Tents and sand slime added opportunities to imagine, touch and explore.
The teachers planned the stations with a purpose: sharing with children from both classes. “Share, please” and “Wait, please” were part of the play as children took turns.
The campsite was make-believe. The practice in patience, communication and kindness was real.

For children aged 2–5, what does inquiry look like in the early years?
At CGK International School in Yokohama, children learn through questions, play, relationships, and hands-on experiences. Our Open School introduces families to the IB PYP approach, daily life at our international preschool, and the care and learning environment children experience at CGK.

Art, light, movement—and learning beyond the classroom.
At teamLab Borderless, CGK Middle School students explored how technology can become creative expression. Sharing the experience also meant practising communication, collaboration and self-management.
Sky Class (5-year-olds) explored world flags, cultures and the history of places, then created airplanes and boats of their own. Curiosity about the world became thinking and making.
CGK Afterschool students explored six types of simple machines around the school, then used their discoveries to begin building hydraulic and pneumatic machines in teams.

Learning does not only happen inside the classroom.
CGK Middle School students observed the structure, height, shapes, patterns, and design of Tokyo Tower. The visit gave them a chance to see how mathematical ideas from class are used in the design and construction of a landmark they could experience for themselves.
Looking at a familiar city from a new perspective can make mathematics feel much more tangible.
