1. Open School and campus visits. The Bashamichi Campus invites prospective families to attend Open School sessions to observe activities and meet staff. Weekend sessions run on specific dates with options in Japanese, English, or bilingual formats, and you can bring your child along to see how daily routines and inquiry activities unfold. The Bashamichi Campus location is 2F, 6-75 Otamachi, Naka-ku, Yokohama, and it is a practical first step to evaluate fit before applying.

Be prepared to indicate your preferred campus (Bashamichi for Preschool) and the age group you are applying for.

3. Admission Screening. A brief interview and behavioral observation are conducted with both the parents and the child.

Parents do not need to be proficient in both English and Japanese; the assessment considers the child's readiness and development.

4. Acceptance and Payment. Enrollment is secured after payment of the required fees.
