We are a clinic of internal medicine and proctology conveniently located a 3-minute walk from the west exit of JR Shinjuku Station. We have the highest number of one-day hemorrhoid surgeries in Tokyo, and our CO2 laser surgery is low stress surgery, so there are almost no restrictions on daily life from the day after the surgery. We are equipped with an AI-equipped multi-slice CT and the latest endoscopes to provide highly accurate medical examinations.
