Kase Clinic

Kase Clinic is a dermatology practice sitting on the ground floor of a small residential building in Tamagawa, Setagaya — a quiet, leafy part of southwest Tokyo that’s home to a lot of long-term expat families. They handle the standard skin stuff: acne, eczema, rashes, moles, allergies, and general skin checks.

The clinic has some English content on their website, which is a decent sign, but don’t assume you’ll walk in and have a fluent English consultation waiting for you. Reality is probably somewhere in the middle — a translation app will help, and pointing at your skin problem goes a long way in dermatology anyway. If your Japanese is zero, call ahead or email first to set expectations.

It’s a neighborhood clinic, not a big hospital department, so the vibe is local and low-key. That can be a good thing — shorter waits, one consistent doctor, and a practice that knows its regulars. Setagaya isn’t the most expat-dense ward in Tokyo, but the area around Tamagawa has enough international residents that some English exposure is plausible.
