IISJ is based in Sengoku, Koto-ku, centred on the CBSE (India's Central Board of Secondary Education) curriculum. Students sit CBSE Board Examinations at Grade 10 and 12, with the IB Diploma reportedly also offered at senior secondary level.

Not the Same School as GIIS Tokyo

Tokyo has several Indian-community-oriented schools. This batch covers IISJ; an earlier batch researched GIIS Tokyo (Global Indian International School). Both serve the same community, but they're run by different operators and are unrelated institutions — worth distinguishing clearly given the name similarity.

William Prep’s Analysis

IISJ's fees stand out as notably lower than most schools researched in this project (¥600,000/yr for Kindergarten-Grade 9). That doesn't signal lower educational quality — it more likely reflects a different cost structure tied to CBSE, India's public curriculum. Fee level alone shouldn't be read as a quality signal; it makes more sense evaluated against the intended destination (Indian universities vs. Japan or an IB-recognising system).

Fees: A Real First-Year Total of About ¥0.63M (Kindergarten-Grade 9)

IISJ's own 2026-27 fee page lists a ¥20,000 registration fee and ¥5,000 emergency/insurance fee as one-time charges. Tuition is ¥600,000/yr for Kindergarten-Grade 9, rising to ¥1,200,000/yr for Grade 10-12. Using Kindergarten-Grade 9 as the base, the first-year total is roughly ¥625,000. School bus fees run ¥150,000-¥360,000/yr (round trip) by area; materials and uniforms are separate.

University Entrance Eligibility in Japan

School-accreditation route	No not publicly confirmedWhether IISJ holds any of the six MEXT-recognised accreditations was not confirmed this session.
Student-qualification route (IB, etc.)	Yes (not independently confirmed)

CBSE alone is not among the qualifications explicitly listed for Japan's individual-credential eligibility route. The IB Diploma offering itself wasn't confirmed directly against the school's own curriculum page this session. Families with specific Japanese-university plans should confirm the actual eligibility route directly with the school.

Might not suit — Families wanting the IB Diploma offering confirmed with certainty before applying (not confirmed against the school's own curriculum page this session)

William Prep’s Analysis

What mattered in researching IISJ was two things at once: avoiding conflation with GIIS Tokyo, and not misreading the lower fee level as lower quality. Evaluating a school by fee level alone misses the point — it needs to be read against the university destination the school is actually built around.

Questions to Ask the School

1.Does the school formally offer the IB Diploma? What is the authorisation status?
Why this matters: Not confirmed directly against the school's own curriculum page this session.
2.Is there truly no capital or operational connection to GIIS Tokyo?
Why this matters: Worth confirming explicitly given the name similarity, to avoid any confusion.
