Dr. Tsurugi Tanaka

About

Dr. Tsurugi Tanaka is one of the two female physicians who staff Tanaka Ladies Clinic Shibuya, and she carries the clinic’s general-gynecology and first-line-treatment side. Her MD came from Gunma University in 2016, followed by initial residency at Kanto-Rosai Hospital and then three hospital appointments in fast sequence — the University of Tokyo Hospital (January 2019), the University of Yamanashi Hospital (October 2019) and the National Center for Global Health and Medicine (2020). That university-and-national-hospital stretch is what stands behind the non-ART half of this clinic’s menu: menstrual disorders, discharge and infection, contraception, cervical and uterine screening.

The fertility training came from clinics rather than wards: Matsumoto Ladies Clinic from 2021 and Phoenix ART Clinic from 2023, both reproduction-specialist practices, then Mitsui Memorial Hospital (2024) and the Shibuya clinic. She enrolled in the University of Tokyo doctoral program in 2021 and completed it in April 2025 without leaving full-time clinical work (source: clinic physician profile page) — a doctorate done between shifts, not before or after a career.

Her stated approach opens at the patient’s side of the desk: she describes infertility treatment as beginning with a woman facing and caring for her own body, and invites questions of any size before protocols start. In practice at this clinic that means she covers the front half of the treatment ladder — infertility work-up, timed intercourse, IUI, gynecologic treatment — alongside the director’s ART programs.

Clinical Expertise

• Infertility diagnosis and staging: baseline screening (hormones, AMH, ultrasound, infection panel) and the stepwise plan — timed intercourse, then IUI, then ART referral within the clinic
• IUI (AIH) and timed-intercourse treatment: cycles scheduled off follicle monitoring — the clinic’s general-infertility track, reported at a 23.3% gestational-sac rate for April-September 2024 across all ages, against a national benchmark of roughly 10%
• General obstetrics and gynecology: menstrual irregularities, discharge and infection, contraception and pill prescribing, cervical and uterine screening
• Reproductive medicine research background: University of Tokyo doctoral training completed 2025, informing protocol and evidence review at the clinic

Why Choose Dr. Tsurugi Tanaka

Hospital-grade general gynecology inside a fertility clinic. Three university-and-national-hospital appointments before she specialized means the differential diagnosis behind “infertility” — endometriosis, thyroid disease, menstrual pathology — gets a certified OB-GYN’s first pass, not an afterthought.

Research training that is current, not decades old. Completing a University of Tokyo doctorate in 2025 while in full clinical practice is a signal of active engagement with ART literature at exactly the career stage when protocol habits form.

Fertility-specific reps, not a general OB pivot. Her path ran through two dedicated ART clinics (Phoenix ART, Matsumoto Ladies) rather than a general practice detour, so cycle monitoring and staging are her default working language.

Professional Affiliations

She holds the Japan Society of Obstetrics and Gynecology’s certified obstetrician-gynecologist credential, and keeps membership in the societies that bracket her corner of the field: the Japan Society for Reproductive Medicine, the Japan Society of Obstetrical and Gynaecological Genetics, the Japan Society of Human Genetics, the Japanese Society for Women’s Health and the Japanese Society of Anti-Aging Medicine. Her profile also appears on the DoctorsFile physician directory, where the listed posts and dates match the clinic’s own profile page.

Suitable For

• Couples at the start of treatment: work-up and first-line therapy — timed intercourse, IUI — are the part of the ladder she owns inside this clinic
• Patients with a gynecologic problem as well as a fertility one: an irregular cycle, an infection screen, a pill prescription gets handled in the same consult room by a certified OB-GYN, with no separate appointment elsewhere
• Second opinions: a 30-minute consultation with a physician trained along a different route from the director’s costs ¥11,000 here — an inexpensive way to pressure-test an ART plan you have already been handed
• People planning several years of treatment: an attending early in her career is the more likely one to still be in the chair at the end of a long protocol
