Yoyogi International School

What Yoyogi International School does

Yoyogi International School is a private, Tokyo-based international day school founded in 1999 by Yuko Muir, operating as an IB World School fully authorized by the International Baccalaureate Organization to deliver the Primary Years Programme (PYP), with curriculum cultivated from the US Common Core and the UK National Curriculum. The school is also accredited by the Council of International Schools (CIS). It currently serves students from Kindergarten through Grade 8 across two central-Tokyo campuses in Shibuya-ku — the original Yoyogi Campus (5-67-5 Yoyogi) and the newly opened Jinnan Campus (9F-10F, 7-1 Udagawacho, opened Spring 2025) — with a maximum class size of 16 students in Kindergarten and small cohorts schoolwide. The target customer segment is families seeking English-medium international education in Tokyo, including Japanese families pursuing globally oriented schooling and foreign-nationals residing in the city.

The school's product surface is structured as a core IB curriculum extended by supporting modules: the Primary Years Programme is the academic anchor, with Kindergarten, EAL (English as Additional Language) support, an extensive cross-Tokyo bus service, and after-school activities as bundled services. Beginning in the 2026-2027 academic year the school will add a PreKindergarten program (ages 4-5) at the Yoyogi Campus and a High School Program starting at Grade 9 (MYP), while pursuing IB Middle Years Programme authorization for Grades 6-10 and Diploma Programme authorization for Grades 11-12, converting the institution into a full PreK-12 IB continuum school. A 7-week Summer School 2026 (June 15 – July 31) extends monetization outside the standard academic year.

Yoyogi is privately held with no disclosed external investment, has roughly 22 employees per firmographic data, and does not publish revenue or tuition figures (industry references for Tokyo international schools cite 2.5-3.8M JPY annually). Distribution is direct via the school's own website, on-campus school tours, an inquiry system, and Facebook/Instagram channels; no channel partners, M&A, or institutional investor involvement is indicated. The school added a new Head of School for the 2026-27 academic year in connection with its expansion.
