Ikebukuro Tounyoubyo Koujosen Kurinikku

This clinic in Ikebukuro sits on the 3rd floor of the FLC Building, a short walk from one of Tokyo’s busiest stations. The focus is tight and deliberate: diabetes and thyroid conditions. That specialization matters — if you’ve been managing a chronic endocrine condition back home and need continuity of care in Japan, this is the kind of place worth knowing about.

The website has some English content, which suggests at least some awareness of international patients, but don’t assume you’ll walk in and have a full English consultation. Bring your medical history translated into Japanese if you can, or use a translation app as backup. The clinic appears to run a standard Japanese outpatient model — appointment-based, relatively efficient, with a focus on ongoing management rather than one-off visits.

Good fit for: expats with existing diabetes or thyroid diagnoses who need regular monitoring and aren’t starting from scratch medically. Not ideal if you need extensive English hand-holding through every step.
