Admissions

Admissions
1. Admissions Process
Step 1 — Inquire and arrange a campus visit. Prospective families should start by making an inquiry or signing up for a campus tour. Applications are welcome at any time, and visiting the campus is encouraged to understand the school's environment. Note that there is no parking available for school tours. The school can be contacted via the Admissions team for questions or to schedule a visit.

Step 2 — Prepare and submit the application with supporting documents and fees. Begin by completing the online application and paying the non-refundable application fee of ¥50,000 for each application. The application requires an Application Form, Confidential Information Form, Record Release Form, a copy of the applicant's birth certificate or passport page, a recent family photo, and the applicant's school records for the past two years plus the current year's progress report. For Readiness Program (kindergarten) and Grade 1, a Kindergarten Teacher's Recommendation is also needed; for older grades there are grade-specific recommendations. The application fee can be paid by credit card or wired to the school's account.

Step 3 — The admissions evaluation includes academic records, testing, and interviews. Students are admitted on the basis of transcripts from previous schools, standardized test results, a screening test, and a personal interview with both the prospective student and the parents. The school reviews documentation and test results to determine fit with the English-based curriculum. Some grades also require teacher recommendations and counselor/principal references as part of the evaluation.

Step 4 — Grade-specific screening steps and timelines. For Readiness Program (RP) and Grade 1, there are on-campus activities such as a group observation (RP) and an on-campus screening (Grade 1) followed by on-campus family interviews. For RP, the process includes a teacher recommendation deadline and a family interview window, with admission decisions communicated after the interview period. For Grade 1, the on-campus screening occurs in early November, followed by observations and a family interview in November–December, with admission decisions typically issued in late January.

Step 5 — Admission decision, offer, and enrollment. Admission decision letters are issued on set dates (e.g., February 28, 2026 for RP and January 31, 2026 for Grade 1 in the 2026–2027 cycle). If offered a seat, enrollment requires payment of the Registration fee within two weeks of the offer. The Re-Enrollment Deposit for returning students is non-refundable but credited toward tuition, and a School Bus or other transportation option may be selected with its own fee.

Step 6 — Post-acceptance steps and forms. After acceptance, families must complete and submit Health Record forms, the Student ID Card Application Form, the School Bus Application Form (if applying for transport), and provide the Final School Report for the current school year. These steps complete enrollment and help the school finalize records.

Notes on fees and payments (embedded in the process): The school lists the following for new entrants: Application Fee ¥50,000; Registration ¥400,000; Development Fund ¥1,000,000; Building Maintenance ¥150,000 per year; Tuition by level: Elementary ¥2,700,000; Middle ¥2,800,000; High ¥2,850,000. Returning students pay a Re-Enrollment Seat Deposit of ¥300,000 and Building Maintenance ¥150,000 plus tuition at the applicable level. Transportation by school bus is available at ¥310,000 one-way or ¥420,000 for both ways. Payments can be made by credit card (for the application fee only) or by bank transfer for the other items; remittances should be made in the student's name with the English spelling of the name and the school ID number. The Re-Enrollment Deposit is credited toward tuition. Cafeteria, accident insurance, and the Corporate Contribution Program are listed as separate items or programs. For full details, view the current Tuition & Fees schedule.

Language of instruction and curriculum: The school operates with an English-based curriculum, and families are expected to support their child's success within that framework. The school does not discriminate in admissions on race, creed, or national origin.

Waitlist/Pool
2. Waitlist Policy and Process
If a grade level is full, students may be placed on a waitlist. Waitlisted students are expected to continue their education while on the waitlist rather than remaining at home; the waitlisted status is valid only until a designated date set by Admissions. Importantly, waitlist placement is not based on a first-come, first-served basis but rather on the individual screening results. Students on the waitlist will be considered for enrollment as soon as a seat opens at their grade level. The waitlist policy applies to each grade-level as appropriate. References: Admissions Policy (turn4search0).

Waitlist/Pool details (additional context): The policy specifies that the waitlist is used when a grade is full and that the process is driven by screening results rather than order of application. The policy indicates the waitlist is grade-specific and has an expiration date determined by Admissions. References: Admissions Policy (turn4search0).
