Nagaoka Clinic
About
Nagaoka Clinic, located in Oshima, Koto-ku, Tokyo, is a community-based medical practice offering internal medicine, surgery, gastroenterology, and diabetology. A key feature of the clinic is its walk-in system—no appointment is needed—and patients are free to leave the waiting area after checking in, making it easy to visit between work or daily activities. The clinic provides a wide range of care, from acute conditions such as colds and fever to lifestyle-related diseases including hypertension, dyslipidemia, and diabetes. When an infection is suspected, the clinic actively performs genetic and antigen testing, and maintains a system that allows febrile patients to be seen without an appointment. In the surgical domain, the clinic handles wound treatment for cuts, chronic pain management for knees and lower back, and surgical procedures for ingrown nails and sebaceous cysts. The gastroenterology department offers a low-discomfort endoscopy using a transnasal endoscope with sedation, with early-morning appointments available from 8:30 a.m. The diabetology department provides specialized care from blood glucose control to complication management, including gestational diabetes. The clinic has established referral relationships with multiple institutions including Koto Hospital, Tokyo Metropolitan Bokutoh Hospital, and the National Cancer Center Hospital, ensuring appropriate referrals when hospitalization or detailed examinations are needed. Barrier-free facilities are also in place, allowing patients with mobility concerns to visit with confidence.
