Fees

Annual tuition at Musashi International School Tokyo ranges from JPY 1,608,000 to JPY 1,819,000 for 2026/27.

Application and assessment fees
- Application (entrance examination) fee by level: Elementary (Year 1–6) — JPY 34,500; Middle School — JPY 39,500; Upper Secondary (Year 10–11) — JPY 82,500; Advanced (Year 12–13) — JPY 89,500.

One‑time initial (pre‑enrolment) fees
- Registration fee (school registration): JPY 200,000.
- Entrance (admission) fee: JPY 300,000 (amount shown for general entry level).
- Campus / facilities development fee: JPY 210,000.
- Example: for a Grade 1 (six‑year‑old) new enrolment the published one‑time initial fees sum to JPY 200,000 + JPY 300,000 + JPY 210,000 = JPY 710,000; the same published source shows the total first‑year cost for Grade 1 (initial one‑time fees plus the annual tuition) as JPY 2,318,000.

Annual tuition fees by year group (published amounts for the 2025/2026 academic year)
- Kindergarten (Kindg.1 / Kindg.2 / Kindg.3): JPY 1,637,000 per year.
- Grade 1 to Grade 5 (Primary Years): JPY 1,608,000 per year.
- Grade 6 to Grade 8 (Lower Secondary / Middle): JPY 1,765,000 per year.
- Grade 9 to Grade 12 (Upper Secondary / IGCSE / A‑Level years): JPY 1,819,000 per year.

Per‑term (three‑term calendar) — illustrative instalments (inference)
- The school operates on a three‑term calendar (Term 1: Sep–Dec; Term 2: Jan–Mar; Term 3: Apr–Jul). If annual tuition is billed in three equal term instalments, each term instalment can be estimated by dividing the annual tuition by three. For example:
- Kindergarten term instalment (estimated): JPY 1,637,000 / 3 ≈ JPY 545,667 per term.
- Grade 1–5 term instalment (estimated): JPY 1,608,000 / 3 ≈ JPY 536,000 per term.
- Grade 6–8 term instalment (estimated): JPY 1,765,000 / 3 ≈ JPY 588,333 per term.
- Grade 9–12 term instalment (estimated): JPY 1,819,000 / 3 ≈ JPY 606,333 per term.
Note: the per‑term figures above are calculated by dividing the published annual tuition by three; the calculation is an inference based on the published three‑term academic structure and the published annual tuition figures. The school's actual billing instalment amounts and whether fees are split equally by term should be confirmed with admissions.

Billing schedule and payment terms (published guidance)
- Admissions notices indicate the typical timing for fee collection during the admissions cycle: the school requires the registration (school registration) payment within two weeks of the offer/acceptance notice, and remaining initial and annual fees are generally required by the July payment deadline preceding the new school year. These payment‑timing points are stated in the school's published admissions announcements.
- A published lump‑sum (one‑time) payment discount is applied in some cases (a one‑time discount for full annual payment at the start of the year is recorded in school fee summaries).

Boarding / residential provision
- The school does not operate boarding residential facilities; it is a day (commuter) school.

Other mandatory and typical additional costs
- Maintenance / school running fees, event fees and PTA membership fees are published as recurring annual charges in the school's fee breakdown for different levels (examples from published level breakdowns): maintenance/“running” fees in the JPY 120,000 range, event/activity fees ranging from JPY 100,000–150,000 depending on level, and a PTA fee of JPY 5,000. These items appear in the school's level‑by‑level fee breakdowns.
- Preschool / kindergarten initial and annual figures differ from primary/secondary figures; one published preschool summary shows an initial fee set (application fee JPY 19,500; registration JPY 200,000; entrance JPY 150,000; facility fee JPY 210,000) and an annual preschool tuition figure of JPY 1,238,000.
- After‑school care (child care to 17:30), extra‑curricular classes, seasonal school programs and school bus services are offered and are charged in addition to standard tuition; published school summaries note that these services carry additional fees. Bus service routes are published but specific bus fees are itemised separately.
- School development / campus fees and other one‑off charges (listed above) are collected at enrolment in addition to the annual tuition amount.

Sibling discounts and concessions (published variations)
- Published information on sibling discounts varies between sources: one published summary records a second child discount of 5% and a third child discount of 30% on tuition; another published school summary records a second child discount of 10% and a third child discount of 15%. These differing published extracts should be noted when assessing sibling concessions.

Refund / cancellation information (published availability)
- The school's published admissions notices state payment deadlines and the timetable for registration and remaining fee payments, but a comprehensive, itemised refund/cancellation schedule (for example specific refund percentages by withdrawal date) is not clearly published in the accessible admissions notices and fee summaries that accompany the fee tables. Parents should note that the school's admissions material sets firm due dates for registration and remaining fees.

Fee payment options (how invoices are issued and typical payment methods)
- Application fees are invoiced and paid through the OpenApply admissions system used by the school; the OpenApply guidance shows how parents obtain an invoice and complete payment of the application fee via the OpenApply invoicing workflow.
- OpenApply / invoicing systems commonly support payment by bank transfer and by credit card (OpenApply/related invoicing documentation lists credit card and bank transfer among accepted invoice payment methods); schools commonly issue invoices that give specific bank transfer details or a payment link. The school's admissions announcements state invoice/due‑date practices and the need to settle registration and other fees by their stated due dates.

Summary of the most significant published figures
- One‑time initial fees commonly published for new primary entrants: Registration JPY 200,000; Entrance JPY 300,000; Campus development JPY 210,000 (total one‑time initial ≈ JPY 710,000). Annual tuition examples (published for 2025/2026): Kindergarten JPY 1,637,000; Grades 1–5 JPY 1,608,000; Grades 6–8 JPY 1,765,000; Grades 9–12 JPY 1,819,000.

Admissions process (step-by-step, current understanding):
1. Info session or campus tour: Families can request an info session or tour through the school's admissions contact options. Sessions are offered in English and Japanese, and you can choose a date/event that fits your schedule. Completing the Info Session/Tour form or emailing the admissions team initiates this step. The school also publishes online information sessions and tours as part of its outreach.
2. Online application submission: Applications are submitted online through the school's admission process. The school has previously announced that applications for the school year are accepted via online formats. Begin the online application as early as possible to secure a seat.
3. Admissions assessment: Applicants may undergo an assessment interview and subject tests, with content varying by grade level and prior reports/transcripts. Assessments are used to determine readiness for Cambridge Primary/IGCSE/A‑Level tracks where applicable.
4. Result notification: Results are communicated within about one week after the interview, depending on grade level and space availability.
5. Registration and deposit deadlines: For accepted applicants, the registration fee is due within about two weeks after notification of the result, with the remaining initial and annual fees due by a specified date. Exact deadlines may vary by year and program.
6. Enrollment and start date: Grade placement is determined by age as of September 1, and the school year typically aligns with Cambridge program cycles (e.g., starting in September). For example, Year 1 starts when the child is of the appropriate age on the cut‑off date.

Notes on current practice and pathways: In 2023–2024, the school announced that Year 1–Year 6 admissions for a September start would be in two phases to accommodate demand, and that applications for the kindergarten were being managed while floor space and class sizes were adjusted. Applications are processed online, and inquiries can be directed to the admissions team.

Languages and program context: Musashi International School Tokyo uses Cambridge International programming and conducts instruction primarily in English; information about Cambridge tracks and age/grade correlations is published in school communications.

Current contact options and info: The school lists an Info Session/Tour form and a direct admissions inquiry channel on its site.
