Mission & Values

CGK's Educational Mission and Code of Conduct


Mission / Raison D'etre

Maximize Your Opportunities for Happiness in an Increasingly Global World

At CGK, we do not decide the specific educational direction children will follow. Children's happiness can take many forms and here at CGK, we'll be close by to support them on their pathway, up until graduation.

After graduation, what kind of future will the children be able to create for themselves? In pursuit of a happy future, there are areas of life where simply cramming information or language education won't really help. Teachers are in a position to support children as individuals, not to impose their own values on them, but to help them think, observe, learn, and grow into independent, life-long learners. By cultivating these abilities and mindsets, we believe they will keep challenging the future, bright-eyed and full of life, even after graduation.

Study-abroad provides a chance to experience a new world. Exposure to different values and ways of thinking allows room to think and grow. CGK gives all students these opportunities. >Study Abroad for 1 Year

Exposure to overseas countries is, of course, just one way to explore the unknown. We want children to acquire knowledge, experience and imagination as early as possible, and to feel that the unknown can quickly become friendly and familiar.

Universally sought, happiness also comes in countless forms. So, it goes without saying that we should provide them with as many options as possible to attain their own happiness.

At CGK, our mission is to "Maximize your opportunities for happiness in an increasingly global world" and to continue our commitment to "Provide quality education to global kids."

We continue to work towards this ideal because we believe that education has great power to bring about peace and happiness. In this increasingly globalized age, we aim to contribute to creating a better and more peaceful world by developing young talent into internationally-minded individuals.

We'll keep nurturing vibrant and resilient children who have hands-on experience with the world, without limiting their possibilities.


Code of Conduct

Providing Quality Education to Global Kids by Nurturing Self-expression, Critical Thinking Skills and a Spirit of Inquiry

When interacting with other people, children need “critical thinking skills,” or the ability to think for themselves, before "self-expression," that is, learning to use language skills, either in English or Japanese. Language is the tool to finally communicate the opinions created this way, but without the interest and motivation that stems from a "spirit of inquiry," which precedes deep thinking, deep thinking will not happen.

Here at CGK, we value the strength and spirit of these three qualities. We understand that teachers themselves must be aware of the flow from "spirit of inquiry" to "critical thinking skills" and, finally, "self-expression." By reflecting this understanding in our daily teaching activities and using our curriculum as a foundation, we will cultivate truly global kids.

A willingness to think and challenge oneself by having a broad perspective and a deep interest in things, which makes one "want to know" and "want to learn" more actively. It is an important mindset to not wait for something to be given to you but to take action on your own and have the opportunity to grow.

The ability to think outside the box, to see and understand things from multiple perspectives, and to create one's own ideas. Critical thinking skills are important, not only in terms of cognitive skills such as problem-solving, but also in terms of non-cognitive skills, such as communication and emotional maturity.

This is not about superficial language skills, but about the ability to understand other people's ideas, to communicate one's own ideas, and to express oneself in order to interact with others. We nurture the desire and joy of interaction in our students, and help them develop the ability to act and speak with confidence.
