Aiaikodomotootona Shika

Aiaikodomo to Otona Shika (the name roughly means “Aiai Children and Adults Dental”) is a general dentistry clinic tucked into the first floor of the Domani Building in Waseda, Shinjuku. It’s a neighborhood practice — not a flashy expat-facing clinic — so walk in expecting a local feel. They treat both kids and adults, which is useful if you’re managing dental care for a whole family.

The website has some English content, which suggests they’ve thought about non-Japanese patients, but don’t assume the front desk will hold a full conversation in English. Come prepared with a translation app or write down your symptoms in Japanese beforehand. Waseda is well-connected but slightly off the main Shinjuku drag — closer to Waseda Station on the Tōzai Line than to Shinjuku Station itself. If you’re in the early Shinjuku area or near Waseda University, this is a convenient option. Best for expats comfortable navigating some language friction in exchange for a solid, community-style dental practice.
