About Us

It is our pleasure to introduce to you Shinagawa International School in Tokyo. SIS was founded in 2007. In the beginning, it was situated inside the Jingumae Public Elementary School Campus in Shibuya-ku. At the end of June 2018, SIS moved to its new campus location near to Shinagawa Seaside Station in Shinagawa, Tokyo.

Shinagawa International School (SIS) in Tokyo now is an IB DP Candidate School and authorized MYP school implementing the MYP/DP curriculum framework. MYP is a continuum of the IB Primary Years Programme and enables students to further develop the skills, knowledge, and attributes they start to acquire in primary school. SIS Main Campus offers classes of Grades 6 to 10 in the 2023 – 2024 Academic Year and Grades 11 – 12 from August 2024.

SIS offers a comprehensive education that incorporates the five essential elements of the IB program (Knowledge, Skills, Attitudes, Conceptual Understanding, and Action). The SIS mission and education philosophy promote a balance of acquiring knowledge, developing skills, and promoting positive attitudes and attributes that will contribute to every student’s capability to be an inspired, lifelong learner.

International Children Day Celebration in Shinagawa International School

Teachers design learning activities that empower students’ academic achievement and personal passion for life-long learning. Social development is a high priority at SIS, and our mixed-age group After School Program activities promote interaction among children of different ages. All lessons, activities, and school events are designed based on our students’ culture, beliefs, and background. Our unique cultural features are respected and celebrated in order to encourage understanding and appreciation of diversity. The result is a challenging, non-discriminatory learning environment that is responsive to the needs of its learners. Teachers plan lessons and learning activities based on students’ needs. A high teacher-to-student ratio allows us to know our students well and differentiate instruction to best help each child achieve his or her learning, personal, and social goals.

The students’ action is represented in SIS vision statement that will guide them to be global learners who contribute towards world peace. On top of this, classes are timetabled with Japanese lessons, depending on the ability of the individual, we follow the books Kokugo (Japanese as a Native Language) or JAL (Japanese as an Additional Language).

SIS is considered to be a community of learners. We are fortunate to have teachers and students from all over the world, resulting in a multicultural and diverse learning community. We celebrate our diversity not only in our regular class activities but also by hosting an International Children’s Festival every year.

ELC students are in Field Trip

Each student is respected as an individual with different strengths and interests. The SIS learning community includes representatives from a wide variety of backgrounds. Events like Japanese Culture Day and Exchange Activities with local schools encourage respect and appreciation for other cultures and our local community in Tokyo.

The SIS learning community is based on mutual respect and open communication between staff, parents, and students. Our parents cooperate in many aspects of school life, such as participating in-class activities, volunteering to enhance our library and media center, accompanying classes on Field Trips, and holding fundraisers like a bake sale for International Children’s Day.

This homepage aims to give you a better insight into the fantastic work we do at Shinagawa International School, and we hope to welcome you to our school in the near future.
