KOYAMA E.N.T and Allergology

KOYAMA E.N.T and Allergology sits in Takenotsuka, a residential pocket of Adachi Ward in northeastern Tokyo — not the most expat-dense neighborhood, but a solid local clinic if you’re living in that part of the city. As the name suggests, they focus on ear, nose, and throat issues plus allergology, which makes them genuinely useful for Tokyo’s brutal cedar pollen seasons and the ear infections that seem to find every kid in Japan eventually.

The clinic operates under a medical corporation and has been serving the local community for years. For English speakers, they have conversational English capability and some English-language resources — enough to get through a standard appointment without full panic. You’re not walking into a bilingual clinic, but you’re also not entirely on your own. Bring your insurance card, a rough idea of your symptoms in Japanese if you can manage it, and expect a fairly typical Japanese clinic experience: efficient, organized, and not especially chatty.

Pediatric ENT and allergy cases are the sweet spot here.
