日本語Nishimachi International School Tokyo: Bilingual Education Guide for Parents (2026)
What parents should know about Nishimachi International School — bilingual Japanese/English education, location, admissions, and who it suits.
Among Tokyo's international schools, Nishimachi International School occupies a unique position: it is not simply an English school with Japanese classes — bilingual Japanese/English development is central to the programme.
What Makes Nishimachi Different
Nishimachi International School emphasizes simultaneous development of Japanese and English — a different goal from pure English immersion schools.
Typical profile:
- Founded in 1949 by Tane Matsukata — one of the oldest bilingual schools in Japan, with roughly 470 students
- English-medium instruction with substantial Japanese language and culture integration
- Popular with internationally minded Japanese families and returnees wanting Japanese literacy
- Located at 2-14-7 Moto-Azabu, Minato-ku (confirm current campus details on official site, as facilities can change)
Not the same as:

- BST (British-influenced)
- Weekly eikaiwa supplement at a Japanese school
