01Tuition & Fees
The Only Fee Schedule We Found Is a 2025-26 Document
The fee PDF retrieved from the school's own site in currently available public information is explicitly titled and dated 2025-26 — one year behind most of the other fee schedules cited across William Prep's other school profiles (mostly 2026-27). No 2026-27 version could be located in currently available public information, and we're saying so plainly rather than presenting a year-old number as current. Fee amounts typically get revised annually — confirm the latest figures directly with the school before applying.
Key Point
This kind of one-year gap is exactly why William Prep's fact-by-fact update structure exists. A fee figure changes every year in a way a school's character or distinguishing features usually don't — so updating that single fact shouldn't require rewriting the surrounding article.
Fees: A Real First-Year Total of About ¥2. 64M (K–Grade 5, 2025-26)
CAJ's own 2025-26 fee schedule lists a ¥30,000 application fee and a ¥430,000 entrance fee as one-time charges. On top of that, an annual ¥55,000 registration fee and ¥170,000 facilities fee apply alongside grade-banded tuition (¥1,950,000 for K–Grade 5). Added together, a genuine first-year total comes to roughly ¥2,635,000. Tuition is reduced 25% for a 3rd or 4th child. New Grade 6–12 students requiring English-as-additional-language support pay a separate ¥107,000 EAL fee.
