An English-heavy liberal-arts school known for strong returnee intake — institutionally linked to, but a separate entity from, International Christian University.
Last reviewed by William Prep: 2026-09-24
ICU High School is a private high school in Mitaka-shi, institutionally linked to International Christian University (ICU) but a legally separate school. Known for its English-heavy liberal-arts approach and strong returnee-student intake. No source consulted in currently available public information mentions the IB — this appears to be an Article 1 school running its own curriculum.

04School Features
The Dormitory Option Itself Is Not Widely Known
ICU High School's own fee page itemizes a dormitory entry fee and annual residence fee, separate from day-student costs. That's unusual for a Japanese Article 1 private high school, and it's an option easy for out-of-commute-range returnee families to overlook. The school's own page flags these as 2025 figures "subject to change" — worth confirming current numbers individually.
Key Point
Schools with ICU High School's profile — a Japanese private school strong with returnees — often get discussed as if day attendance were a given. Whether a dormitory exists can be the deciding factor in whether a family outside commuting range even puts the school on their list, which is exactly why confirming it explicitly here matters.
What Makes This School Distinctive
A dormitory option, unusual for a Japanese private high school
An optional boarding arrangement alongside day attendance
The school's own fee page itemizes both the entry fee and annual residence fee.
An easily-overlooked but important option for returnee families outside commuting range.
Who Might Find This School a Good Fit
Might suit — Returnee families wanting an Article 1 Japanese diploma in an English-heavy environment
Might not suit — Families planning specifically around the IB Diploma
