A century-old IB school in Yokohama that moved into a new Kengo Kuma-designed campus in 2022.
Last reviewed by William Prep: 2026-09-24
YIS opened on 27 October 1924 with six students and one teacher in a rented YMCA classroom. It closed during WWII and reopened at its original Yamate site on 15 September 1955. The school introduced the IB Diploma in 1986, replacing British "A" Levels, and moved to a new Kengo Kuma-designed campus in Honmoku in January 2022 — marking its centenary on 27 October 2024.

01Tuition & Fees
Fees: A Real First-Year Total of About ¥5. 27M (Grade 6–11)
YIS's own 2026-27 fee schedule lists two one-time charges: a ¥50,000 application fee and a ¥1,480,000 registration fee. On top of that, an annual ¥399,000 campus development fee applies alongside grade-banded tuition (¥3,345,000 for Grade 6–11). Added together, a genuine first-year total comes to roughly ¥5,274,000. The bus, uniforms and cafeteria are billed separately, though the school's fee page doesn't publish those amounts.
Key Point
Either way, it's a one-time charge worth budgeting for explicitly rather than assuming it's in the same range as elsewhere.

A Century of History: From Wartime Closure to a New Campus
According to the school's own history page, YIS had grown to over 100 students from 21 nationalities by 1939, before closing in 1941 under wartime government restrictions; the original campus was destroyed in the 1945 air raids. It reopened on 15 September 1955 at its Yamate site, graduated its first class in 1973, and moved from British "A" Levels to the IB Diploma Programme in 1986.
