A New Hub for Fertility Care Opens at Otsuka Hospital

For many people struggling to conceive, access to fertility treatment can make all the difference. This summer, the Tokyo Metropolitan Government (TMG) took another step toward supporting those individuals with the opening of a new Fertility Clinic at Tokyo Metropolitan Otsuka Hospital.

According to the Japan Society for Reproductive Medicine, approximately one in 8.55 babies born in Japan in 2023 were conceived through assisted reproductive technology (ART), including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). A 2021 survey by the National Institute of Population and Social Security Research also found that one in 4.4 couples has experienced infertility testing or treatment.

As fertility treatment becomes increasingly common, access to affordable care has expanded. In 2022, ART became covered by Japan’s public health insurance system, and TMG has since expanded financial support for advanced fertility treatments.

Expanding Access to Reproductive Healthcare

In response to these developments, Tokyo Metropolitan Otsuka Hospital established its new Fertility Clinic, the first of its kind among Tokyo’s 14 metropolitan hospitals.

“As a metropolitan hospital, we want to ensure that Tokyo residents have access to reproductive medicine through the public health insurance system,” says Dr. Sanada Yuko.

Governor Koike has likewise emphasized the importance of expanding access to fertility care, particularly for patients who may face challenges obtaining appropriate treatment. “To provide care tailored to each individual’s circumstances, Tokyo Metropolitan Otsuka Hospital has established a new fertility treatment,” she said at a press conference.

Comprehensive Reproductive Care and Advanced Technology

Tokyo Metropolitan Otsuka Hospital provides comprehensive services covering infertility treatment, pregnancy, and childbirth. It also offers fertility preservation therapy for patients whose future fertility may be affected by treatments such as chemotherapy or radiation therapy.

To support high-quality care, the clinic has introduced state-of-the-art equipment, including a time-lapse incubator. Traditionally, embryos had to be removed from an incubator and observed under a microscope to monitor their development. Built-in cameras allow embryos to be monitored continuously without removing them from the controlled culture environment.

“This significantly reduces stress on the embryo,” Dr. Sanada explains.

In addition to public health insurance coverage, Tokyo residents who meet certain requirements may be eligible for financial assistance for advanced fertility treatments started on or after April 1, 2026, helping to reduce the financial burden associated with treatment.

Supporting Patients Every Step of the Way

The clinic’s dedicated team consists of two physicians and two embryologists.. Their goal is to create an environment where patients feel comfortable seeking advice and discussing concerns.

Alongside advanced medical technologies and equipment, this commitment to personalized, patient-centered care is one of the clinic’s defining strengths.

As fertility treatment becomes an increasingly integral part of family planning in Japan, initiatives such as the new Fertility Clinic aim not only to improve access to medical care but also to help people make informed decisions about their future with greater confidence.
