Introduction

At Shinagawa International School, we strive to nurture inspired, independent lifelong learners who are balanced academically, artistically, socially, and physically. Through personalized instruction and diverse activities, we create a non-discriminatory environment that fosters academic achievement, social development, and personal growth, all aligned with the core elements of the International Baccalaureate curriculum. Our teachers design activities that empower students’ academic achievement and foster a love for continual learning, while promoting social development through mixed-age group interactions in the After School Program. We create an inclusive environment that embraces students’ diverse needs and backgrounds, offering personalized instruction through a high teacher-to-student ratio. Our curriculum follows the five essential elements of the International Baccalaureate—Knowledge, Skills, Attitudes, Conceptual Understanding, and Action. With a focus on community, SIS encourages collaboration and open communication between staff, parents, and students, with active parent participation in various school activities.
