Nishimachi International School

What Nishimachi International School does

Nishimachi International School is a private, nonprofit K-9 day school (gakko hojin) founded in 1949 by Tané Matsukata, located on a seven-building campus at 2-14-7 Moto Azabu, Minato-ku, Tokyo. It serves approximately 468 students from Kindergarten through Grade 9 with English-language instruction (American Common Core, NGSS, and AERO standards) supplemented by daily Japanese language and culture classes taught using the CEFR proficiency model. The faculty comprises 55 teachers (48% with advanced degrees, 9-year average tenure) plus 20 administrative staff, delivering a 1:7 student-to-teacher ratio and an average of 20 students per class. The student body is drawn primarily from Tokyo's expatriate community (diplomatic and corporate families) and Japanese families seeking international education, with a smaller cohort of Outreach Scholarship recipients supporting socioeconomic and cultural diversity.

The school's product set spans Elementary School (K-5) and Middle School (6-9) programs, the Japanese Language and Culture Program, School Trips anchored by the Kazuno outdoor education center in Gunma Prefecture, Student Services (Learning Services, English Language Services, Counseling, and the Exceptional Potential Program), the Yashiro Media Center library of 17,000+ items, and optional fee-based Summer Programs and After School Care. Technology infrastructure centers on a Connected Learning program with school-wide network access and 1:1 iPad deployment in middle school, Veracross for constituent management and admissions, and Teamie as the middle school learning portal; no proprietary AI/ML systems are deployed.

Revenue is generated almost entirely from tuition and fees: ¥3,129,000 annual tuition (paid quarterly), a non-refundable ¥30,000 application fee, a ¥300,000 registration fee, and additional mandatory fees including ¥825,000 building maintenance, ¥200,000 education enhancement, and ¥200,000 school growth fund contributions. Secondary revenue streams include After School Activities/Care, Summer Programs, and the Kazuno camp. The go-to-market motion is direct-to-consumer via the Veracross admissions portal, in-person campus tours, Head of School Tours, and an annual Open Campus, with a small share of Online Open House Presentations for overseas families.
