Yokohama Kokusai High School is a Kanagawa Prefectural public high school that established an IB course — a Dual Language Diploma Programme (DLDP) — within its International Studies Department in FY2019. Like Tokyo Metropolitan Kokusai High School (already profiled by William Prep), it's one of the few public schools in Japan offering the IB Diploma.

01Tuition & Fees
Fees: Standard Public-School Rate Plus Unconfirmed IB Costs
As a Kanagawa Prefectural school, base tuition follows the standard public-school rate set by the prefecture. On top of that, third-party sources report additional IB-related materials and training costs in the range of ¥100,000-200,000+/yr, but the school's own itemized fee page wasn't accessible directly in currently available public information (a 404 on direct fetch).

| Cycle | 一般入試（約20名）・特別入試（帰国生対象、約5名） |
University Entrance Eligibility in Japan
| School-accreditation route | Yes (estimated) |
| Student-qualification route (IB, etc.) | Yes |
On top of the Article 1 graduation route, a student completing the IB Diploma via the DLDP track also qualifies via the individual-credential route — the same dual-route structure as Tokyo Metropolitan Kokusai High School (already profiled by William Prep).

What "Dual Language DP" Actually Means
This school's IB course teaches only English and Maths in English — Japanese language, history, sciences, and music are taught in Japanese. Worth understanding that this is a genuinely different model from a full-English DP, not a lighter version of the same thing.
Key Point
This isn't a lesser version of the IB — it's a deliberately different design, letting students earn an internationally recognised credential while keeping most learning grounded in Japanese. For a family without full confidence in English, or wanting to preserve Japanese-language thinking skills, that's arguably the better fit. But a family expecting an English-immersion environment specifically would find the reality doesn't match that expectation.

Who Might Find This School a Good Fit
