There is a dedicated space allocated for vaccinations. The area for signing-in, waiting, examination and vaccination is completely separated from the general examination rooms. We provide an online-appointment service*, so you can choose the most convenient day and time for your child’s vaccination.


When you need to visit our clinic, you can make an appointment through the auto-answer phone call system or reserve online*, even if it is your first visit.


An immediate blood and/or urine test will be conducted in case of a bacterial infection, Kawasaki disease, or if another serious disease is suspected, or when the patient has been suffering from a fever for more than 24 hours.

We have an isolated room in addition to the general examination rooms. When an infection such as chicken pox or mumps is found, the medication will be conducted in this isolated room.


The clinic doctor is a specialist in not only clinical pediatrics, but in pediatric neurology and pediatric allergy.
The quality of his treatments for atopic dermatitis, asthma, hay fever, nocturnal enuresis, febrile seizure, epilepsy, and ADHD are widely respected. Parents who have a cold, hay fever, or migraine can see the doctor as well. He offers referral to Saitama Kyodo Hospital, Kawaguchi Municipal Medical Center, and other major hospitals when the patient needs advanced medical treatment.
