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 480 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:

• ASIJ (American, English-primary)
• BST (British-influenced)
• Weekly eikaiwa supplement at a Japanese school
