Prime International School offers "Prime Junior," an international preschool and kindergarten, as well as academic afternoon school for returnees, "Prime Academia".

If you are considering raising bilingual children, Prime Junior is an excellent solution. Through our time-tested phonics and reading program, your child will attain native-level English ability before entering elementary school.
Our philosophy is to offer the kind of educational experience normally only afforded to children living in English-speaking countries. We are confident that our curriculum, a combination of education and entertaining activities, will promote your child's growth in and out of the classroom.
For those parents who want a well-rounded education for their children, please come and check out Prime Junior!
In addition to our standard preschool and kindergarten curriculum, we offer courses to help students prepare for rigorous entrance examinations to exclusive Tokyo-area international schools.


Prime Academia is Prime International School’s total culmination of our time-tested educational program targeted specifically toward returnee children. Prime Academia, an afternoon international school, aims to prepare children for the global arena as we provide various academic classes, such as reading, writing, science, and more.

We value and encourage children to hypothesize, make inferences, experiment and analyze while fostering their abilities to think for themselves.

We also offer classes for those with no overseas or international school experiences called Pre-Academia where students will be studying Phonics and other basic skills.
