Admission to GiS involves five steps: initial contact with the school, a campus visit/tour, submission of the application form, a family (parent and child) interview, and registration upon acceptance. The Japanese admissions materials also indicate that an academic achievement test and a classroom trial visit for the child are part of the process. Fees are communicated privately via invoice after acceptance; no public fee schedule is available. Rolling enrollment appears to be the norm; families should contact the school directly for available start dates.
