SIS reportedly opened in 2007 in Shibuya-ku, relocating to its current Higashi-Shinagawa (Shinagawa-ku) site in 2018 — and the school's name reflects that post-move location. It's an authorised IB continuum school (PYP/MYP/DP).

What Japanese Families Should Know
Questions to Ask the School
1.Does SIS itself hold a WASC or other MEXT-recognised accreditation?
Why this matters: Public information does not establish this clearly; confirm it directly with the school.

04School Features
The Name Reflects Its Current Location, Not Where It Started
The name "Shinagawa International School" might suggest it was founded in Shinagawa-ku, but it reportedly started in Shibuya-ku in 2007 and moved to Shinagawa in 2018. Worth keeping this relocation in mind when tracing alumni networks or older institutional history.
Key Point
A relocation history like this usually isn't a deciding factor in school choice, but understanding accurately why a school carries the name it does is still worth doing when evaluating a school's history and institutional stability. Relocating itself is unremarkable — many schools go through it as part of growing.
What Makes This School Distinctive
A school that relocated from Shibuya to Shinagawa
Founded 2007 in Shibuya-ku, relocated to Shinagawa-ku in 2018
Multiple third-party sources consistently report the founding location and relocation year.
A good example of why a school's name alone shouldn't be assumed to reflect its full history.
Who Might Find This School a Good Fit
Might suit — Families for whom commuting to Higashi-Shinagawa is realistic
Might not suit — Families prioritizing a long, unbroken institutional history at one site (this school has relocated)
