Ario Kitasuna Hifuka Arerugi-ka

Ario Kitasuna Hifuka Arerugi-ka is a dermatology and allergy clinic sitting on the third floor of the Ario Kitasuna shopping mall in Koto-ku — which means you can pair your appointment with a grocery run, at least. The mall setting makes it easy to find and accessible by local bus from Nishi-ojima or Ojima stations on the Toei Shinjuku line.

The clinic covers standard dermatology — rashes, eczema, acne, skin allergies — and explicitly handles allergy consultations, which is genuinely useful for expats dealing with Japan’s brutal cedar pollen season or mystery food reactions.

Their website has some English-language content, which suggests they’re aware foreign patients exist. That said, don’t assume you’ll walk in and have a fully English conversation with reception or the doctor. Come prepared with your symptoms written out, a translation app ready, and your insurance card. It’s a neighborhood clinic, not an international one — but for skin and allergy issues in eastern Tokyo, it’s a solid, accessible option.
