About St. Mary's International School

St. Mary’s International School was founded in 1954. It moved to its current location in Setagaya ward in 1971. At St. Mary’s, we nurture the intellectual, physical, emotional and social development of each student. Our challenging array of core curricular and extra-curricular programs is designed to enable each student to achieve excellence and success. We provide a positive and safe learning environment, where a spirit of cooperation, friendship and mutual respect helps to maximize individual achievement.

The St. Mary’s experience goes from kindergarten to grade 12. We offer the International Baccalaureate course of studies, a globally recognized and rigorous pre-university program designed to give students the competitive edge they need for both university studies and their later careers. St. Mary’s is fully accredited by two agencies that provide standards and procedures for school improvement: the Western Association of Schools and Colleges (WASC) and the Council of International Schools (CIS).

WASC is one of six regional associations that accredit public and private schools, colleges and universities in the United States and East Asia. CIS is a membership organization of international schools around the world.

I went to St. Mary’s 60 years ago for one year. What a place. Had a field on top of the school. Had to stand in the corner in the stairwell for talking in line. My family lived in Washington Heights. Great memories although I was only 6.

I attended St Mary’s International School in Tokyo, Japan from 1956-1959 from 4th through 6th grades. Living at Grant Heights/Mutsumi Dai, I had a one hour bus ride to school each day. I remember a long rising road to gates and a large stone mansion which served as the school. A modern building was erected while I was there. My appreciation for diverse culture began in Japan and at St Mary’s. The brothers were great teachers and rational disciplinarians. My best and most favorite academic experience.

Middle and high school curriculum is well organized. However, elementary school principle (DiMuzio) is not professional and biased against certain race.
