東陽町東口クリニック, located in Toyōchō, Kōtō-ku, Tokyo, is a clinic specializing in Kampo internal medicine. Drawing on Traditional Chinese Medicine, the clinic addresses symptoms that are difficult to diagnose through Western medicine and chronic conditions that have been slow to improve. It treats a wide range of conditions including physical ailments such as sensitivity to cold, shoulder stiffness, and fatigue, as well as medically unexplained symptoms, autonomic imbalance, psychosomatic disorders, and anxiety. Beyond internal medicine, the clinic also handles dermatological conditions (acne, eczema, rosacea), gynecological concerns (premenstrual syndrome, menopausal disorders, infertility), and allergic diseases (hay fever, asthma, atopic dermatitis). In recent years, the clinic has also been treating post-COVID sequelae and post-COVID-vaccine symptoms, primarily using Kampo-based approaches for a diverse range of conditions. The clinic also places importance on the role that hidden anemia (low ferritin levels) and vitamin D deficiency may play in various health issues, offering molecular nutrition-based dietary guidance when necessary. Initial consultations are by appointment only, and follow-up visits on Saturdays and after 6 PM on weekdays also require reservations. Treatments are covered by health insurance.
