Located in Miyacho, Kumagaya City, Saitama Prefecture, Matsui Internal Medicine Clinic provides medical care centered on internal medicine. Situated in an easily accessible location—a 15-minute walk from Kumagaya Station and 5 minutes from the Kyoku-mae bus stop—it offers parking for up to 8 cars and barrier-free facilities. In addition to internal medicine, the clinic provides gastroenterology, cardiology, respiratory medicine, and pediatrics, and recommends various health screenings. Ultrasound screenings involve radiation-free imaging, while gastrointestinal endoscopy examines the esophagus, stomach, duodenum, and large intestine to identify conditions such as gastritis, polyps, gastroesophageal reflux disease, and Helicobacter pylori infection. In vascular screenings, blood pressure is simultaneously measured on both arms and ankles to assess arterial stiffness and stenosis, aiming to detect arteriosclerosis early. Bone density screenings measure bone mineral content and are used for early detection of osteoporosis and evaluating treatment effectiveness. English services are available, and the clinic is committed to providing open healthcare that supports the health of the local community.
