Matsuzakaya Dental Clinic, operated by Medical Corporation Yuwakai, is situated on the 8th floor of Matsuzakaya Ueno Store in the Ueno area of Taito Ward, Tokyo, just a 2-minute walk from Okachimachi Station. A defining feature of this clinic is its broad treatment schedule covering Sundays and national holidays, with only January 1st and 2nd as annual closing days, making it exceptionally accessible. Hours run from 10:00 AM to 7:00 PM, spanning the lunch break into the evening, so patients can conveniently stop by after work or while shopping. Services range from a preventive dentistry foundation through cosmetic dentistry and whitening, orthodontics (including clear aligners), dental implants, oral surgery, pediatric dentistry, root canal treatment, and dental anesthesia (intravenous sedation administered by a specialist), enabling the clinic to serve as a comprehensive dental practice meeting diverse needs from children to the elderly. A team-based care model with multiple dentists—including female practitioners—facilitates shared expertise and treatment tailored to each patient's condition. On-site CT equipment supports precise surgical procedures such as implant placement. The clinic is also a designated training institution, accepting trainees year-round from Nippon Dental University and Taiyo Dental Hygienist College, fulfilling an educational role. Credit cards and electronic payments are accepted, and barrier-free facilities are in place, creating a welcoming environment for a wide range of patients.
