Oyama Dental Clinic is a specialized dental clinic located in the prestigious Kioicho area of Chiyoda Ward, Tokyo, within the Hotel New Otani Tokyo The Main. With excellent access from Nagatacho Station and situated in a district surrounded by business offices and government buildings, the clinic offers a convenient environment for those with busy schedules. Operating hours are from 10:00 AM to 1:00 PM and 2:00 PM to 6:00 PM, with a two-session schedule including a lunch break. English-language support is available, enabling flexible communication for patients who require assistance in a language other than Japanese. The clinic also offers parking facilities, making it convenient for patients who prefer to visit by car. Furthermore, the barrier-free design ensures that patients using wheelchairs or those with physical disabilities can receive care with peace of mind—an important feature that, combined with the hotel's high-standard facilities, enhances the clinic's overall accessibility. The clinic is closed on Sundays, public holidays, and during the New Year period, Golden Week, and Obon holidays, so patients are advised to confirm the schedule in advance before visiting.
