NO DIAGNOSIS YET

No diagnosis yet.
Can we still come?

Many families wait because they think they need a diagnosis first. In Japan's system you do not — and waiting for one is the most common way that support starts later than it needed to.

The short answer

You can visit us, talk with us and have your child assessed without any diagnosis. To use the service regularly, your child needs the certificate from your ward — and the certificate does not require a diagnosis either. In our experience, almost every family who applies receives it.

What the certificate needs instead

The ward needs to see that support would help your child. A doctor's opinion letter (意見書), a health-check record with a recommendation, or a referral from the ward's child development support centre usually serves. None of these is a diagnosis. Your ward office tells you at the first consultation exactly which document they want; in Shinjuku the counter is the Disability Welfare Division, Support Section (03-5273-4583). A disability handbook is not required.

What a diagnosis does and does not change

  • It does not change whether your child can attend child development support, or the fees.
  • It does not decide school placement — the ward's school-entry consultation looks at the child as a whole, with you.
  • It can help later for some things (certain handbooks, some school arrangements, understanding your child) — and a diagnosis can be sought at any time from a paediatric or child-psychiatry clinic. Support does not have to wait for it.

Where to get an assessment

Two public routes in Shinjuku: the ward's child development support centre "Aiai" (03-6273-8701) for developmental consultation and assessment, and the four public health centres for the infant health checks and consultations. Other wards have the same. At our classroom, speech-language therapists assess your child's communication, and the Tanaka-Binet intelligence test is available; a diagnosis itself is made only by a doctor.

The grey zone is who this is for

"Grey zone" (グレーゾーン) is the everyday word for children who show some characteristics but do not have — or do not meet the criteria for — a diagnosis. Child development support was designed for exactly this: for support to start when it would help, not when a label is ready. Many of the children at our classroom have no diagnosis. If you are noticing something, that is reason enough to visit.

This page is general information for families, based on the Japanese pages of our classroom and the public sources listed above. It is not medical advice and does not replace an assessment by a doctor or other specialist. Whether your child needs support, and which class your child enters at school, are decided with you by the relevant professionals and your ward — not by this page.

FAQ

Questions families ask

Will the ward ask us to get a diagnosis?
Usually not. A doctor's opinion letter or similar is the typical requirement. Your ward office will tell you exactly what they need.
Can you diagnose our child?
No. Diagnosis is made by a doctor. We assess communication and development and build the support plan; we can tell you where to go for a medical assessment if you want one.
Is it better to wait and see?
Visiting costs nothing and commits you to nothing. Getting a clear picture early gives you options; it does not take any away.
