Yotsuya Station (Marunouchi Line) — 2 min walk
  • Orthodontics and general dentistry combined
  • Near central Tokyo
  • OKUNO Dental Office sits on the 4th floor of the Sanpan Building in Yotsuya, Shinjuku — a quiet corner of the ward that’s easy to reach from Yotsuya Station. The clinic covers both general dentistry and orthodontics, so if you’re dealing with a toothache today and want to talk braces next month, you’re in the right place.

    Their website has some English content, which is a good sign, but don’t assume the front desk will be fully fluent. English capability here is partial at best — enough to handle basics, probably not enough for a complicated treatment discussion without help. Bring a translation app or a Japanese-speaking friend if your situation is anything beyond routine.

    Yotsuya is well-connected and not overwhelming — it’s not Shinjuku Station chaos, which is a genuine relief when you’re already anxious about a dental visit. The building elevator situation means you’re not walking into a ground-floor clinic, so factor that in if accessibility matters to you.

    Solid option for expats in the Yotsuya-Shinjuku corridor who need a dentist that at least acknowledges international patients exist.

    Patient Feedback

    Patient feedback points to a calm, unhurried atmosphere — this doesn’t feel like a high-volume conveyor-belt dental clinic. Doctors are reported to be thorough during exams and take time to explain what they’re finding, which matters a lot when you’re already navigating a foreign healthcare system. Wait times appear reasonable. The 4th-floor location keeps foot traffic low. No strong patterns of complaints about billing surprises or rushed appointments.

    English Language Proficiency

    The clinic has English content on its website, which suggests some awareness of international patients — but that doesn't guarantee a fluent English speaker at reception. Realistically, expect basic English for scheduling and check-in, with things getting harder once you're in the chair discussing treatment plans. Forms are likely Japanese-only. A translation app like Google Translate will carry a lot of weight here. If your Japanese is zero, consider calling ahead to gauge comfort level before booking.
