Start with the curriculum, age range, language of instruction and support your child needs, then look for a place in the intended grade and start date. Places are allocated grade by grade, so a citywide school count or waiting-time range is only background.
The Tokyo Metropolitan Government’s international-school portal lets families search by location, school level, curriculum and accreditation. Use it to identify schools and then confirm details directly. Inclusion in a directory is not a guarantee that a school will suit your child.
A school’s legal classification, the authority responsible for its approval and the scope of any external review are each worth knowing. Terms such as kakushu gakko, a school’s operating entity and international accreditation describe different things. Avoid treating any one of them as a complete description of oversight or quality.
