Admissions	Admissions
Admissions	Admissions 1. Registration and initial inquiry. Parents should initiate contact to register their child and to understand the documents that will be requested later in the process. The school provides explicit age criteria to guide placement, with age as of 1 April used to determine suitable grades (e.g., Nursery 2 years 6 months; JR.KG 3 years 6 months; SR.KG 4 years 6 months; Grade 1 5 years 6 months). This step sets the foundation for eligibility and next steps in the admissions timeline. 2. Submission of the application and required documents. After registration, you will receive a call to submit the application form along with the documents listed by the admissions team. Key documents include photocopies of academic records from lower kindergarten and above, four recent passport photos, photocopies of health insurance card and passport/birth certificate, vaccination chart, residence card, and the Family Information Form and Health Research Form. A complete health checkup record must be completed within two weeks of joining. A note states that the admission fee paid is non-refundable. 3. Admission assessment and personal interview. The applicant undergoes an admission assessment and a personal interview as part of the evaluation process. These steps help determine suitability for the program and placement. The admissions team will communicate outcomes and next steps to the family after the assessment and interview. 4. Offer, acceptance, and fee payment. If admission is offered and accepted, the admission fee must be paid to complete the admission process. For Grades 1–12, the one-time Admission Fee is 55,000 yen. The fee is payable by bank transfer, and remittance charges are borne by the parents. The Tuition and other fees are described separately, and the policy notes that fees paid are non-refundable once submitted. 5. Orientation and parent briefings. A date for an orientation of parents will be conveyed by mail as part of the onboarding process. This step provides an opportunity for parents to become familiar with school routines and expectations before the child starts. The age criteria and approved placement will guide the orientation focus. 6. Withdrawal policy and final administrative steps. If you withdraw, the withdrawal should be requested at least two months before the intended date of departure. If the withdrawal request is late, the next two months' tuition may be payable, and a transfer certificate will not be issued until the necessary payments are settled. This policy appears in the age/withdrawal guidance published on the admissions page.	Admissions Step 0 — Fees (context for admission): First-year fees comprise a combination of one-time charges and annual costs. The application fee is 20,000 JPY, the enrolment fee is 60,000 JPY, and a Building Fund of 84,000 JPY is charged in the first year. The total of these first-year charges is 884,000 JPY. Ongoing annual fees vary by grade, typically ranging from 804,000 JPY to 1,084,000 JPY depending on the level, with a 20% discount for the second child and a 30% discount for the third child when applicable. Prices are illustrative for the 2025–2026 cycle and subject to change. Step 1 — Submit Online Application: The admissions process begins with submitting the online application. A non-refundable processing fee is charged for each application and the fee is valid for one academic year. This step starts the review process and indicates the family's intent to pursue admission. Follow-up steps will be communicated after the fee is received. Step 2 — Submit Supporting Documents: After submitting the online application, families are asked to provide the required supporting documents as instructed by the Admissions Team. The documents are requested to support the application and confirm eligibility and fit for the school's cohort. Timelines for document submission are provided by the Admissions Team and alignment with the review schedule is important. Step 3 — Admissions Team Review: Fully completed applications are reviewed by the Admissions Team to assess suitability, space availability, and alignment with the current cohort's language and learning makeup. The review determines whether an offer can be extended and may consider individual circumstances. Decisions at this stage reflect both academic considerations and the school's capacity. Step 4 — Admissions Decision: The school issues an admissions decision to the family once the review is complete. The decision is communicated to the family and may be contingent on space availability and other factors identified during the review. If admission is offered, next steps for enrollment and fee payment are provided. Step 5 — Enrollment, Orientation and Start Date: If admitted, families proceed with enrollment and payment of applicable fees. The school holds an Admission Ceremony in the first week of April for new entrants, and there is historically a strong pattern of admissions occurring in April; mid-year entries may be possible if vacancies exist. Final start dates and orientation details are provided as part of the admissions decision communications.
Scholarships	Scholarships Scholarships: Kohana International School does not publish any scholarship program on its admissions or fee pages. The available information covers admission steps, required fees, and payment policies, but there is no mention of scholarships or financial aid programs on the school's site. Families seeking financial assistance options should contact the admissions office for current offerings, if any.	Scholarships —
Waitlist	Waitlist Waitlist/Pool: There is no published waitlist or pool policy on Kohana International School's admissions pages. The admissions procedure describes enrollment steps but does not include any waitlist or pooling mechanism. Parents should plan for an admissions sequence based on registration, assessment, and payment rather than a waitlist process.	Waitlist Waitlist / Pool: Tokyo Bay International School operates a waitlist (wait pool) system. A waiting list exists as a channel to fill seats when vacancies arise. For the new academic year, a March 5 deadline is noted for registration, and students can join the waitlist after a fully completed application is in place; waitlisted offers are typically valid for one academic year. If a vacancy opens, those on the waitlist may be offered admission.
