Okamoto Internal Medicine Clinic, located directly above Kiba Station on the Tokyo Metro Tozai Line, is a specialized clinic focusing on lifestyle-related diseases, particularly diabetes treatment. One of its key features is its high convenience—being directly connected to the station, patients can visit the clinic without getting wet even during bad weather. The clinic operates on a complete appointment-only basis, establishing a system that ensures sufficient consultation time for each patient while minimizing waiting times. The clinic director, Dr. Aki Okamoto, is a female physician with certification as a diabetes specialist, and she provides medical care alongside multiple full-time and part-time doctors. Additionally, all staff members have obtained certification as Certified Diabetes Educators, creating an environment where patients can receive specialized support not only from doctors but from the entire staff as a unified team. In terms of medical services, the clinic conducts abdominal, carotid artery, and thyroid ultrasound examinations 2-3 times per month. It also actively introduces equipment and examinations useful for diabetes management, such as providing continuous glucose monitoring devices (FreeStyle Libre) as elective treatment even for non-insulin users. A thyroid internal medicine department is also on-site, and referrals to medical institutions capable of performing cytology are made when necessary. Reflecting the clinic's policy of emphasizing the understanding of blood glucose control status, regular blood and urine tests form the foundation of their medical practice, demonstrating the clinic's approach to patient care.
