What is an International School?

International schools in Japan are educational institutions where the primary language spoken is not Japanese; this, usually being English. The curriculum is based on the country where that school is from, making it different from regular Japanese schools.

International schools are getting increasingly popular internationally, and Japan is not the exception. This is mainly due to the fact that these schools provide an environment where a global mentality is nurtured, which is something that is becoming more and more important.

Since there are many definitions of “International School”, the number of schools varies a lot depending on who you ask. In Tokyo alone, this number can go from 24 to 44. many of these are Pre-schools due to their increasing popularity.

One type is those whose curricula are based on the country these schools are from such as France, Canada, and the US. The other type is those who have more flexible curricula such as  Montessori or Waldorf education.
