Curriculum and academics

Tokyo West International School opened in 2010 as an elementary school in Tachikawa and grew into an all through bilingual school serving the western suburbs. Its distinguishing feature is the genuine two language model: rather than treating English as a subject, the elementary years are taught through both English and Japanese, built around units of inquiry so that children learn content and language together. The elementary programme follows an IB Primary Years Programme framework, and the middle and high school years move to internationally aligned standards while keeping the inquiry based method.

The school folds in mathematics drawn from the Singapore approach and a strong thread of technology and project work, which is part of how it positions itself against the larger central Tokyo schools. To understand how the inquiry based primary framework connects to later international pathways, see our pillar guide to the IB curriculum, and our Tokyo city guide for the wider landscape of international schools in the city.

Because the school sits in the western suburbs rather than the diplomatic centre, it draws families who live out that way and want a bilingual international option close to home. For households balancing Japanese and English at home, the deliberate two language model is the main reason to look here rather than at an English only school.

Tokyo West International School fees

Tokyo West International School fees sit in the lower-mid band for the city, below the premium schools clustered in central Tokyo. The bilingual model and suburban location keep the headline tuition more accessible than the diplomatic district schools, but the published cost is still built from several components.

• Registration and application: a one off charge at the point of applying.
• Annual tuition: billed per year, often by term.
• Materials and resources: books and classroom consumables.
• Extras: lunch, transport, after school care and trips.

For a citywide comparison, our guide to international school fees in Tokyo breaks the market into low, mid and premium tiers, and our list of the cheapest international schools in Tokyo shows where a suburban bilingual school sits against the central options. We avoid quoting precise figures because schools revise them each year.

Admissions

The intake follows the school year, with applications handled directly by the school rather than a shared portal. Because the model is bilingual, the admissions conversation usually covers the child's language balance in English and Japanese alongside prior school records and an age appropriate assessment. Families should contact the office to confirm the current window, the documents required and the level of each language expected for the section.

A visit is the best way to see the two language classroom in action and to judge whether the suburban setting suits your daily routine. Mid-year places can open outside transition years, so families relocating to western Tokyo partway through the cycle should ask directly.

Location and who goes there

The campus is in Tachikawa, a major hub in western Tokyo well served by rail and surrounded by green space and family housing. The location is convenient for families based across the western suburbs who would otherwise face a long commute to the international schools concentrated in the city centre.

The community mixes Japanese and international families drawn to the bilingual model and the suburban setting. For a fuller picture of districts, commutes and the wider schooling options, our Tokyo city guide maps where expatriate families settle and how the schools are spread across the city.
