Sakamotoshikaiin

Sakamotoshikaiin is a neighborhood dental clinic tucked into the Yayoi Building in Oshima, Koto Ward — eastern Tokyo, not the most expat-heavy area, but solidly connected by the Toei Shinjuku Line. It’s a general dentistry practice covering the usual range: cleanings, fillings, extractions, and likely some cosmetic work.

The English situation is genuinely unclear. Their website has some English-facing content, which suggests awareness that non-Japanese patients exist — but that doesn’t always translate to English-speaking staff at reception or during treatment. If your Japanese is minimal, go in prepared: have a translation app ready, write down your symptoms beforehand, and don’t assume smooth communication.

This is probably a fine local dentist for someone living nearby who can manage basic Japanese or bring a bilingual friend. It’s not a clinic that’s built its identity around serving expats. If you need guaranteed English support, look elsewhere. If you’re in Koto Ward and just need your teeth sorted, it’s worth a call to check current English availability before booking.
