Shinagawa International School (SIS), founded in 2007, offers the full International Baccalaureate continuum: the Primary Years Programme (PYP), Middle Years Programme (MYP), and Diploma Programme (DP). The Seaside Campus serves Grades 1–3 and forms part of the school’s PYP pathway across SIS campuses in Tokyo. Located in the Shinagawa Seaside area, the campus is supported by practical student services, including an organised school bus system with multiple routes and on-site daycare for younger children. Student life includes a structured afterschool programme with activities spanning arts, sports, academic clubs and service initiatives, as well as residential trips and swimming classes that are part of the school programme. SIS also operates a four-week Summer School, which features hands-on projects across science, technology, engineering, arts and mathematics, along with weekly field trips. These programmes reflect the school’s emphasis on inquiry-based learning and real-world experiences within the IB framework.
