Located in Ginza 4-chome, Tokyo, Okabe Kampō Naika is an internal medicine clinic specializing in integrative medicine that combines Western medicine with traditional Chinese medicine. Adopting an integrative medicine approach that has been gaining attention in Europe and the United States in recent years, the clinic practices diagnosis and treatment based on the systemic pathology theory of traditional Chinese medicine for a wide range of conditions that are considered difficult to treat with Western medicine alone, including epilepsy, depression, muscular dystrophy, ulcerative colitis, Sjögren's syndrome, chronic nasopharyngitis, and post-COVID syndrome. In particular, improvements through herbal medicine treatment for post-COVID syndrome have been reported, making it a potential option for patients suffering from intractable conditions. Another distinctive feature of the clinic is that the director, who has experience in cancer research at the University of Tokyo, also provides second opinions for advanced-stage cancer with metastasis. Clinic hours are from 11:00 AM to 6:00 PM (with a break from 2:00 PM to 2:30 PM), open Tuesday through Friday.
