Tsubasa Clinic

Tsubasa Clinic is a dermatology practice in Katsushika, one of Tokyo’s quieter eastern wards, sitting right at the entrance of Shin-Koiwa Station. That location is genuinely convenient — you step off the train and you’re basically there. The clinic runs under the medical corporation Tokyo Hakuhoukai, so there’s some institutional structure behind it, not just a solo GP doing skin stuff on the side.

The website has some English-facing content, which is a decent sign, but don’t assume you’ll walk in and have a smooth English conversation at the front desk. That’s unconfirmed. Bring Google Translate or a Japanese-speaking friend if your Japanese is zero. For skin conditions — rashes, acne, eczema, moles, whatever’s going on — this is a dedicated dermatology clinic, so you’re at least in the right place. Katsushika isn’t exactly expat central, so if you’re coming from Shinjuku or Shibuya, factor in the commute. But if you live east, this is a solid neighborhood option worth knowing about.
