Iwai Fess Clinic

Iwai FESS Clinic is a specialist orthopedic clinic in Minami-Koiwa, Edogawa — not the most central location for most expats, but reachable via the Sobu Line. The name gives it away: FESS stands for Functional Endoscopic Sinus Surgery, but don’t let that throw you — this is an orthopedics practice focused on minimally invasive spine and joint procedures. The clinic has some English content on its website, which suggests at least some awareness of international patients, but full English-language service on the ground is not confirmed. Bring a translation app or a Japanese-speaking friend if your Japanese is limited. It’s a small clinic setup inside a commercial building, so expect a quieter, more focused environment than a large hospital. If you’re dealing with a spine issue or joint problem and want a clinic that leans toward less invasive approaches, this is worth looking into — just go in prepared for a language gap.
