Ishii Surgery

Ishii Surgery is a small dermatology clinic tucked into Shinjuku’s Sumiyoshi-cho area — residential enough that it’s not the kind of place you stumble across, but easy to reach from central Shinjuku. Despite the “surgery” in the name, the focus here is skin: rashes, acne, eczema, mole checks, and the usual dermatology bread and butter.

The website has some English content, which is a decent sign, but don’t book expecting a fully bilingual experience. Reception is likely Japanese-only in practice. Bring a translation app, have your symptoms written out in Japanese if you can, and you’ll probably be fine — this is a standard neighborhood clinic, not an international medical center. The doctor appears to handle consultations directly without much fanfare. Good for routine dermatology needs if you’re living or working in the Shinjuku area and want something close without trekking to a hospital.
