Shinagawa International School

  • Age: Ages 3-15
  • Area: Shinagawa (Tokyo)


Shinagawa International School (SIS) is an IB PYP-accredited school situated within a walking distance to Shinagawa Seaside station. The school offers preschool classes (ages 3 and 4), primary school (K-G6), and middle school class G7 (2020-2021 Academic Year). SIS was originally established in 2007 in Shibuya, but it was relocated to its current premises in Shinagawa at the end of June 2018.

Nourishing and celebrating diversity 

SIS is considered to be a community of learners. The school is fortunate to have teachers and students from over 30 different nationalities which form a great mixture of different experiences and cultures and results in the formation of a multicultural and diverse learning community. SIS celebrates its diversity not only in regular class activities but also by hosting an International Children’s Festival every year.

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 its mixed age group After-School Program activities promote interaction among children of different ages. All lessons, activities, and school events are designed based on students’ cultures, beliefs, and backgrounds. SIS’s 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 which is responsive to the needs of its learners.

Respect for individuality and unity

Teachers plan lessons and learning activities based on students’ needs. A high teacher-to-student ratio allows the school to know its students well and differentiate instruction to best help each child achieve his or her learning, personal, and social goals. 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. Parents cooperate in many aspects of school life, such as participating in class activities, volunteering to enhance the library and media center, accompanying classes on field trips and holding fundraisers like a bake sale for International Children’s Day.
