Ohtawara Dental Clinic is a dental clinic located in Negishi, Taito Ward, Tokyo. The clinic offers English services and is equipped to meet diverse language needs. The clinic is generally closed on Sundays and holidays, as well as during year-end and New Year, Golden Week, and Obon periods. Updates on the official website suggest that shortened clinic hours or closures due to meetings or other circumstances occur frequently, such as shortened hours until 5:00 PM or 6:00 PM, afternoon closures, or morning closures several times a month. These operational practices suggest that the clinic is actively involved in local dental association activities and continuous professional development. It is also noted that in January 2026, price revisions were made for some self-pay treatments due to rising material costs.
