KUBO Dental Clinic

KUBO Dental Clinic sits on the second floor of the Dai-3 Toei Building in Oshima, Koto Ward — not the most central spot in Tokyo, but a solid neighborhood clinic that serves the local community well. They handle standard dental work: checkups, cleanings, fillings, extractions, the usual. The clinic operates under the medical corporation 歯笑会 (Shishoukai — roughly “dental smile society”), which suggests a practice that takes its professional identity seriously.

English capability here is conversational — staff can get through a basic appointment without you needing to mime a toothache, but don’t expect fluent clinical explanations in English. If you have a complex issue or specific treatment questions, bring a Japanese-speaking friend or prep some vocabulary in advance. The website is Japanese-only, so booking and research will require some effort if you can’t read Japanese. That said, for routine dental care in the Koto area, this is a legitimate option for English speakers who need something functional rather than fancy.
