HM Ladies Clinic Ginza is located in Ginza 3-chome, Chuo-ku, Tokyo, just a one-minute walk from Ginza-itchome Station. Opened in June 2020, it is a specialized obstetrics and gynecology clinic. Director Hirotaka Masuda brings over 24 years of experience gained at multiple medical institutions including Keio University Hospital and holds several specialist certifications: board-certified obstetrician-gynecologist, reproductive medicine specialist, endocrinology and metabolism specialist, and certified endoscopic surgeon. The clinic treats infertility, menstrual disorders, endometriosis, adenomyosis, and uterine fibroids, while also offering outpatient hysteroscopic surgery and reproductive surgical procedures, providing a comprehensive range of obstetric and gynecological care. Its guiding principle of "minimally painful medicine" is reflected in practices such as allowing patients to opt out of pelvic examinations when desired, helping to lower barriers to seeking care. Reception hours extend until 8:00 PM, creating an accessible environment for working women. A 24-hour online reservation system is available, and credit cards and electronic payments are accepted for added convenience. Other patient-friendly features include the active use of generic medications and integration with the women's health management app LunaLuna Medico.
