Shinjyuku 3 chome Sikaiin
Shinjuku 3-chome Sikaiin sits on the 6th floor of the SHA Building in the heart of Shinjuku — one of Tokyo’s busiest areas, which means you’re never far from here if you’re already in the neighborhood. It’s a general dental clinic covering standard dental work: cleanings, fillings, extractions, and likely cosmetic and restorative options too.
The website has some English content, which suggests they’ve thought about international patients, but don’t assume the chair-side experience will be fully bilingual. English capability at reception and during treatment is unconfirmed. That’s not a dealbreaker — plenty of expats navigate Japanese dental clinics just fine with a translation app and some patience — but go in with realistic expectations.
Location-wise, being steps from Shinjuku 3-chome Station makes this genuinely easy to reach from almost anywhere in Tokyo. For a dental emergency or routine care when you’re based in or around Shinjuku, this is a convenient option worth a direct call or email to check current English support before booking.
Patient Feedback
Public review data for this clinic is limited, so take this with a grain of salt. The Shinjuku 3-chome location means it serves a dense mix of locals and people passing through. Patients at similarly sized Shinjuku dental clinics often report reasonably short waits when appointments are booked in advance. The sixth-floor setup is a standard Tokyo clinic arrangement — functional, not fancy. No strong signals of long waits or rushed appointments either way.
English Language Proficiency
For translating forms, prescriptions, or discharge summaries, Jozu is worth having on your phone.
