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.
Key Point
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.
What Makes This School Distinctive
Strong facilities, but ending at Grade 8
A rooftop pool and black box theatre, but no high school division
The school's own fee schedule only has bands through Grade 8.
A middle-school-stage transfer needs to be planned for.
Who Might Find This School a Good Fit
Might suit — Families near Ikuno-ku, Osaka wanting strong facilities through the middle-school stage
Might not suit — Families wanting one school from kindergarten through high school graduation
