IB PYP Candidate School with Inquiry-based Curriculum
Providing World Standard Childcare and Global Education

Through "childcare" and "global education" from early childhood, CGK International School nurtures the physical and mental growth of children to provide them with infinite future possibilities. As an IB PYP candidate school, we offer a high-quality inquiry-based learning curriculum and aim to develop future lifelong learners.

What we nurture in these early childhood years are not only "cognitive skills," which are directly manifested as learning outcomes, but also "non-cognitive skills," such as communication and emotional maturity, which are important throughout the future. As an integrated school that continues through high school, we also focus on social-emotional learning, emphasizing appropriate timing and approach rather than short-term results.

We arouse children's interest and curiosity in new worlds and nurture them to have a truly global perspective.

Fulfilling Childcare & Education Program

At CGK, children are cared for full time from 8:30am to 5:00pm (8:00am to 7:00pm if extended care is included). There are no shorter hours or less than 5 day-a-week courses. (Only 2 year olds can choose from 2-5 days per week.)

While providing attentive care as a preschool, we offer a full curriculum along with a variety of programs, which are of the highest standard in both quantity and quality.


IB Education

CGK has introduced the IB program, which is highly acclaimed around the world, and as an IB PYP candidate school, we implement an inquiry-based learning curriculum. One of CGK's founding missions has been to help our children develop a spirit of inquiry, and being an IB PYP candidate school is very important to us.

Through the IB transdisciplinary program, children naturally connect and understand the basic knowledge and concepts of multiple subjects without being aware of the boundaries of the subjects. IB is an ideal form of education in which children actively and vigorously enjoy inquiring and learning, rather than the old image of learning in which students sit in chairs and mechanically work on assigned tasks. Because it is student-centered, children naturally deepen their learning as if they were playing.


Preschool in Japan

All of our Japanese teachers are qualified nursery teachers (hoikushi). Appropriate support by highly professional nursery teachers who are familiar with the growth of children in early childhood is very important not only for childcare but also for the quality of education, and we also collaborate with parents appropriately. As a preschool in Japan, we flexibly incorporate the best aspects of both Japan and other countries to provide childcare and education that emphasizes the development of non-cognitive skills based on a foundation that emphasizes children's wellbeing.

During daily Japanese language classes, children learn what they would learn in a Japanese preschool or kindergarten, such as cooperation, consideration, discipline, manners, etiquette, songs, crafts, musical instruments, and offer seasonal events, in cooperation with non-Japanese classes. With Japanese language time, IB inquiry-based learning is also approached in both English and Japanese to deepen inquiry and understanding.



We have adopted the Singapore Maths curriculum, widely recognized as the best math curriculum in the world. Students who learned Singapore math regularly test the highest in international assessments such as the PISA test.

Our grade aligned math skills take into account the standards of multiple countries, including Japan, and are designed to ensure our students will be well prepared for any academic challenges regardless of where they may continue their learning after CGK.

Food Education

We collaborate with an Italian restaurant and farmers to create food education programs. On a daily basis, we not only teach the importance of food and good manners, but also offer a variety of hands-on experiences.

In the farming experience, we not only enjoy harvesting, but also provide special experiences with an awareness of the aim of each one, such as weed pulling, plowing, planting, cooking with the harvest, and cooking lessons by professional chefs and renting out a restaurant to experience a course meal. Using the example of food distribution from producer to consumer, we are working to deepen understanding of food from diverse perspectives. In a series of activities, we actively incorporate the SDGs into our food education, not only from the perspective of our daily lives, but also from the larger perspective of global issues related to food.


P.E. / Swimming

Our P.E. and swimming classes are taught by professional instructors. The P.E. classes are based on the inquiry-based learning of the IB program, rather than just physical exercise and physical fitness.

We also offer year-round private swimming instruction in a heated indoor facility. Through 42 lessons starting at Age 3 class, students will learn the fundamentals of swimming.


Authentic Experiences

Through a variety of events, both large and small, both inside and outside the school, students learn and experience many things that lead to a diverse spirit of inquiry.

These experiences are made possible with the cooperation of the local community (partners) and CGK student's families. We actively incorporates field trips as part of the children's inquiry-based learning, welcoming guest teachers and visiting various locations by school bus to further enhance the education provided to the children.


Optional Classes

We offer optional classes after 4:30pm on weekdays to further nurture our children's individuality, abilities, and interests.

Programming and dance are offered in English, and Pygmalion and Ronri Engine are offered in Japanese. Pygmalion uses a math approach, while Ronri Engine uses a Japanese (Kokugo) approach to foster logical thinking. The Ronri Engine helps children attending international schools to further strengthen their Japanese language skills.


Study Abroad

We offer a variety of programs to encourage children to become independent, lifelong learners. In addition to educational activities conducted under a student-centered policy on a daily basis, we offer programs such as hiking, international exchange events, Machinaka Ryugaku, overseas tours and short-term study abroad programs for parents and children so that children can gradually step up and become independent according to their level.

We place particular emphasis on our study abroad programs, and while we offer a variety of programs abroad, we strongly recommend going abroad because it gives children the opportunity to experience a new world. Exposure to different values and ways of thinking allows room to think and grow. Many of these programs can be participated in from preschool age.
