Iris Women's Clinic Musashikoganei

Iris Women’s Clinic Musashikoganei is a gynecology-focused clinic on the third floor of Cosmos Building in Koganei City, a quieter residential pocket of western Tokyo. It’s part of the Iris clinic group, which operates several women’s health locations across the city. The clinic covers standard gynecology: menstrual issues, contraception, STI testing, prenatal checkups, and menopause care.

The website has some English-language content, which is a good sign — but don’t assume that translates to a fully English-capable front desk. Walk-in situations or complex consultations will likely go smoother with a translation app or a Japanese-speaking friend in tow. This is a neighborhood clinic, not an international medical center, so set expectations accordingly. That said, the Iris group has more patient-facing materials than most comparable local clinics, so you’re not starting from zero.

Musashikoganei Station on the Chuo Line puts you about 10-15 minutes from Shinjuku — accessible, but not central.
