The New International School of Japan (NewIS) is a well-established international day school in Ikebukuro, Tokyo, founded in 2001. It is widely recognized for its distinctive dual-language (English and Japanese) developmental approach and its multi-age classroom structure, where students learn in three-year age groupings rather than traditional single-grade levels. Serving students from age 3 through Grade 12, the school follows a Vygotskian philosophy that emphasizes social interaction, collaboration, and knowledge construction. Accredited by MSA-CESS and the Council of International Schools (CIS), NewIS offers an American high school diploma within a highly inclusive, non-competitive environment that values diversity, multilingualism, and individualized growth. With approximately 200+ students representing over 30 nationalities, the school fosters strong teacher-student relationships through its three-year classroom cycles. The urban campus includes open-plan learning centers, an indoor gym, art studios, music rooms, and a science laboratory, while also utilizing local parks and community facilities for physical education. Known for its supportive culture and strong bilingual development, NewIS is an excellent choice for families seeking a progressive, inclusive, and developmentally responsive education in Tokyo.
