Shinmi Masanori Clinic, located in Fujimi, Chiyoda-ku, Tokyo, is a self-pay medical clinic specializing in medical oncology and Kampo internal medicine, just a 3-minute walk from JR Iidabashi Station's west exit. The clinic's most distinctive feature is its cancer treatment using the herbal medicine "Huai Er," which achieved top-tier evidence at the American Society of Clinical Oncology. This herbal medicine is approved as an insurance-covered anticancer drug in China, and its effectiveness on survival rates was confirmed in a large-scale randomized clinical trial of 1,000 cases published in the prestigious medical journal "GUT" in 2018. Dr. Masanori Shinmi, the clinic director, has over 40 years of medical experience and opened the clinic in 2020 after early retirement from a university hospital. The clinic's philosophy is not to deny standard treatments, but to expand the possibilities of cancer treatment through evidence-based combination of herbal and Kampo medicines. The clinic treats a wide range of immune-related conditions, including patients undergoing cancer treatment, intractable diseases, and COVID-19 aftereffects. Since treatment is primarily through oral medication, hospital visits and IV infusions are unnecessary. Remote consultations are available from the first visit, enabling patients from across Japan and overseas to receive care. The clinic accepts credit cards and electronic payments, and has parking facilities.
