Yuushukai Medical Corporation

What Yuushukai Medical Corporation does

Medical Corporation Yuushukai (医療法人雄秀会) operates as GYN Medical Group, a private Japanese medical corporation founded in 1974. It serves women through three Tokyo clinics in Ikebukuro, Shibuya, and Ichigaya, each positioned within a five-minute walk of a station. The group provides gynecological consultation, examination, surgery, screening, vaccination, contraception, pregnancy-termination, and related dermatology services.

Its service portfolio includes menstrual-disorder treatment, oral and emergency contraceptive prescriptions, IUD insertion, HPV testing and vaccination, cervical-cancer screening, at-home HPV self-sampling, STI testing and treatment, microwave endometrial ablation, and other surgical procedures. At Ichigaya, it also offers cosmetic dermatology such as laser hair removal, IPL photo facials, massage peels, and Milanopeel. GYNONLINE extends consultations, prescriptions, and testing-kit access beyond the clinics; the supplied data does not disclose its software architecture or any proprietary AI or automation systems.

The business is primarily fee-for-service. Revenue is generated from insurance-covered consultations and qualifying treatments and from self-pay procedures and products, including cosmetic dermatology. Patients access the group through appointments and walk-ins at its clinics, physician-reviewed online content, promotional campaigns, and the GYNONLINE/gyn.shop storefront. Pricing is not comprehensively disclosed, and no revenue, patient-count, or headcount data are available.

Broad incumbents

• SBC Medical Group Holdings: Tokyo-listed parent of the SBC Shonan Cosmetic Surgery chain, the largest multi-clinic aesthetic and women's services operator in Japan. Comparable as a Japanese multi-clinic medical group running high-volume urban clinics, although SBC is much larger and weighted toward cosmetic surgery rather than core gynecology.
• TBC Group: Long-established Japanese beauty and wellness clinic chain with multiple urban locations. Comparable as a Japanese multi-clinic operator in women's personal care services, though TBC is focused on hair removal and aesthetics rather than gynecological medicine.

Emerging players
