Osaki Kodomo Heart&Allergy Clinic

Osaki Kodomo Heart & Allergy Clinic sits on the ground floor of a residential building in Kita-Shinagawa, close to Osaki Station — easy to find if you know what you’re looking for, easy to miss if you don’t. The clinic focuses specifically on kids with cardiac conditions and allergies, which is a genuinely rare combination in one practice. That specialization matters if your child has been flagged for a heart murmur or is dealing with food allergies, asthma, or eczema.

The website has some English-language content, which is a good sign, but don’t assume that means smooth English consultation. It likely means the clinic is aware of international patients, not necessarily that reception or the doctor will switch languages mid-appointment. Come prepared with a translation app and written notes about your child’s symptoms and history. For complex cardiac referrals especially, bring documentation from any previous providers.
