OWIS Osaka, located in Ikuno-ku, reportedly combines American, British, and IB curricula through project-based learning, as an IB PYP candidate school. Facilities include a rooftop pool, a black box theatre, a gymnasium, and dedicated spaces for robotics, 3D printing, and digital media.

A School That Ends at Grade 8 — Plan for a Transfer
OWIS Osaka's fee schedule has bands only from Early Childhood through Grade 6-8 — nothing beyond that. Like Yoyogi International School (ends at 15), also researched in this project, this isn't a school that carries a student from early years through high school graduation; a transfer is needed at the middle-school stage.
William Prep’s Analysis
The strong facilities (rooftop pool, black box theatre, etc.) are a real draw for the early-years-through-middle-school stage — but the fact that a separate high school destination is needed afterward should be factored in from the start of school selection, not discovered later.
Fees: A Real First-Year Total of About ¥1.68M (Early Childhood)
OWIS Osaka's own 2026-27 fee schedule (tax included) lists an ¥80,000 application fee as a one-time charge. On top of that, an annual ¥50,000 resource fee applies alongside grade-banded tuition/building fee (¥1,548,000 for Early Childhood), for a genuine first-year total of roughly ¥1,678,000. Siblings receive a 25% tuition discount.
University Entrance Eligibility in Japan
| School-accreditation route | No not publicly confirmedSince this school ends at Grade 8, the university-eligibility question only becomes relevant after a student has transferred elsewhere. |
| Student-qualification route (IB, etc.) | No not publicly confirmed |
Since this school ends at Grade 8 (middle school level), the university-eligibility routes don't directly apply to this school itself. Whichever high school the student transfers to afterward will determine the eligibility route.

William Prep’s Analysis
Researching OWIS Osaka surfaced the same "ends partway through" pattern found at Yoyogi International School. This pattern recurring multiple times across this batch confirms it's a genuinely common school structure, not an isolated one-off.

1.Has IB PYP authorisation been formally granted, or is it still at candidate stage?
