Kokubunji Family Naika
Kokubunji Family Naika is an internal medicine clinic sitting on the third floor of the Tenka Building in Kokubunji’s Minami-machi neighborhood — a quiet residential part of western Tokyo that’s home to a fair number of long-term foreign residents. The clinic handles the bread-and-butter stuff: colds, chronic conditions, lifestyle diseases, general checkups. It’s a family practice setup, so they’re used to seeing a range of ages and health situations.
The website has some English-facing content, which is a decent signal, but don’t walk in expecting a fully bilingual experience. English support at the counter is unclear, and the doctor’s English ability isn’t publicly confirmed. If your Japanese is minimal, bring a translation app or a Japanese-speaking friend for your first visit. That said, the clinic’s willingness to put up English content suggests they’re not hostile to foreign patients — just don’t expect your hand to be held through the whole process.
For expats living in or around Kokubunji, this is a solid local option for routine internal medicine needs.
Patient Feedback
Patient feedback points to a neighborhood clinic feel — not a big busy hospital, which means shorter waits than you’d get at a major facility. The doctors appear thorough for routine internal medicine visits. It’s the kind of place where you see the same doctor more than once, which matters for managing ongoing conditions. No reports of staff being unwelcoming to foreign patients, but the experience likely varies depending on who’s at the desk that day.
English Language Proficiency
For translating forms, prescriptions, or discharge summaries, Jozu is worth having on your phone.
