Located in Ginza, Chuo Ward, Tokyo, Ginza Prima Clinic is a clinic specializing in breast surgery for women. Dr. Michiko Koike, the director, graduated from the University of Tokyo Faculty of Medicine, gained experience at the University of Tokyo Hospital and the Cancer Institute Hospital of JFCR, and established the clinic in 1998. A distinctive feature of the clinic is that all staff members—from physicians, radiologic technologists, and ultrasound technicians to administrative staff—are women, creating an environment where patients can comfortably discuss sensitive breast concerns. Services range from breast cancer screenings combining palpation, mammography, and ultrasound, to addressing symptoms such as lumps and nipple discharge, providing second opinions after breast cancer diagnosis, and offering post-surgical chemotherapy and regular follow-ups. The clinic operates on a fully appointment-only basis, ensuring smooth visits with minimal waiting time. The clinic respects each patient's right to choose, including confirming their preference regarding disclosure of diagnosis, and follows a patient-centered treatment philosophy. The clinic is also actively involved in supporting patients who have undergone breast cancer surgery.
