Admissions	Admissions
Admissions	Admissions Step 1 – Gather the documents. Collect the items listed in the admissions guidance: Academic Records for applicants in Grade 1–12; Proof of payment of the application fee of 30,000 JPY; a scan of the student's passport or birth certificate for birth-date verification; photos of the student and guardian(s); a guarantee letter from the employer if the company will pay school fees; and any individualized learning plan (ILP) or other supporting documents. This collection ensures the admissions team has complete material to begin with and supports a smooth review. The documents are used to determine eligibility and placement, and to facilitate the review of the application package. Step 2 – Submit your application. Submit the online application and complete all checklist items in your account. The online submissions are routed through the school's admissions portal, and submitting the form triggers the review process once all required documents are received. This step marks the transition from document gathering to formal review. Step 3 – Submission Review. After online submission, the child may be invited for an interview and a placement assessment. The placement assessment helps determine the appropriate class placement and whether English as an Additional Language (EAL) support or other specialized assistance is required. The outcome of the assessment informs next steps and potential supports. Step 4 – Application Decision. Following the assessment and review of prior school records, the school decides whether the child may register. Families are notified by email as soon as possible of the outcome, and the actual registration occurs at this stage if a place is offered. This decision ties together assessment results, records, and space availability. Step 5 – Enrollment Begins. The admissions office determines the first day of the school, and a family orientation may be organized if applicable. A WIDA test for English as an Additional Language (EAL) learners will be conducted as part of the enrollment process. Enrollment activities culminate in the start of the new school term.	Admissions 1. Eligibility. The school accepts applicants who are foreign nationals or Japanese nationals with prior international education. At least one residing parent must be fluent in speaking, reading, and writing English. Applicants must live with at least one parent within commuting distance while enrolled at YIS. 2.

Our Admissions Team Reviews Your Pre-application. The Admissions Team reviews the pre-application to confirm eligibility and may request additional information by email. If there are issues regarding eligibility, follow-up communication will occur. 4. Complete Application in The Admissions Portal and Pay Application Fee. Return to the Admissions Portal to complete the forms and upload required documents so the school can form a full picture of the child's suitability for the program. Payment of the application fee is part of this step. 5. Document Submission. Submit all requested documents through the Admissions Portal to support the application review. Ensuring all documents are uploaded helps avoid delays in processing. 6. Application Review & Notification Of Admission Decision. The Admissions team reviews the complete application and aims to notify applicants within a few weeks for overseas submissions. There is rolling admission for overseas applicants due to space constraints. For entry at the beginning of the school year (August), apply by early March (early February for high school). 7. Respond To Admissions Decision. If admitted, the family should respond to the admission decision to indicate whether they will enroll. This response typically follows the notification of the decision. 8. Complete Online Enrollment and Pay Registration Fee.

Waitlist	Waitlist Horizon Japan International School uses a rolling admissions policy with a space-available basis. Applications are reviewed and considered as spaces open up, and there is no published waitlist system; families are typically informed by email if a place becomes available or if further steps are required. This approach means that admissions can occur at various times during the year depending on vacancies.	Waitlist When the number of eligible applicants exceeds available spaces, applicants may be placed in a wait pool if deemed acceptable. Priority is given to siblings of current students, children of YIS staff and alumni, returning students, and dependents of organizations participating in our Corporate Contribution Program (CCP). Applicants in the wait pool are requested to submit updated school reports to confirm continued interest.
