Dr. Takashi Okuno

About

Dr. Takashi Okuno is an adjunct physician at Kato Ladies Clinic (KLC) in Shinjuku, Tokyo, and one of the clinic’s longest-serving senior clinicians. He first worked at KLC in 1996 alongside its founding team era, returned to the clinic permanently in 2000, and rose to Deputy Director in 2013 before continuing in a senior physician role.

He graduated from Miyazaki Medical College in 1989 and entered the Department of Obstetrics and Gynecology at Yamanashi Medical University. Between academic training and his KLC career, he served as Chief of Obstetrics and Gynecology at Uenohara Town Hospital, a role that put him in charge of an entire regional maternity and gynecology service.

With more than 35 years in obstetrics and gynecology and nearly three decades inside Kato Ladies Clinic specifically, Dr. Okuno has practiced through the entire modern history of Japanese IVF, from conventional stimulation protocols to today’s natural-cycle and mild-stimulation standards.

Clinical Expertise

• In Vitro Fertilization (IVF): long-cycle patient management within KLC’s minimal-stimulation and natural-culture program, informed by three decades of protocol evolution
• Intracytoplasmic Sperm Injection (ICSI): fertilization support for male-factor infertility, practiced since ICSI’s early adoption in Japan
• Female infertility diagnosis: ovulation disorders, endometriosis and tubal factors, with conservative, low-intervention treatment planning
• Second-opinion consultations: perspective for patients who have undergone years of treatment elsewhere

Why Choose Dr. Takashi Okuno

Dr. Okuno belonged to the leadership generation of Kato Ladies Clinic, serving as its deputy director in 2013. His career is effectively institutional memory of the clinic’s treatment philosophy, useful for patients who want decisions made from deep familiarity with how KLC protocols actually perform over time.

His period as chief of obstetrics and gynecology at a regional public hospital means he has managed labor, emergencies and general gynecology as a department leader, a breadth many lab-focused fertility specialists never acquire.

Patients with long infertility histories or advanced reproductive age often value his conservative approach: he trained in an era that prized careful indication-setting over maximum intervention, which aligns closely with KLC’s modern gentler-treatment ethos.
