Arai Dental Clinic

Arai Dental Clinic sits in Den-en-chōfu, one of Ota’s quieter, leafier neighborhoods — not the first place expats think to look for a dentist, but worth knowing about if you live in that part of southwest Tokyo. The clinic covers standard dental work: cleanings, fillings, checkups, the usual. Their website has some English content, which suggests at least some awareness of non-Japanese patients, but don’t assume you’ll walk in and have a full English conversation at the front desk. Come prepared — a translation app, your insurance card, and any relevant dental history written out in Japanese if possible. It’s a small neighborhood clinic, not a big international-facing operation. That’s not a knock — plenty of expats prefer a local dentist who knows their patients over a polished multilingual chain. Den-en-chōfu is well-connected by Tokyu Tōyoko and Mekama lines, so access from central Tokyo is reasonable. Best suited for expats already settled in Ota ward who want a nearby option rather than trekking into Shinjuku or Shibuya.
