5 Recommended Fertility Clinics in Tokyo [2026] | Comparison Based on Public Data and Track Records

For those considering fertility treatment in Tokyo, we have compared clinics with high treatment success rates and strong public performance records based on public data.

This time, we have selected 5 clinics based not on reviews or name recognition, but on the live birth rate for frozen embryo transfers in patients aged 35–39, and the number of egg retrievals, ICSI procedures, and frozen embryo transfers performed.

We hope this serves as a helpful reference for those struggling with how to choose a hospital and finding the medical institution that is right for them.

※Updated July 31, 2026. This article is based on public information available as of July 2026. Treatment success rates use 2019–2020 data published by the Tokyo Metropolitan Government, and treatment volumes use 2023 performance data listed in the Children and Families Agency's medical institution search.


Selection Criteria

Clinics meeting the following conditions were targeted.

2019–2020 Tokyo Metropolitan Bureau of Social Welfare and Public Health Public Data
・Aged 35 to under 40

2023 Children and Families Agency Public Data
・Top 30 in egg retrieval volume

Even if the live birth rate is high, figures can fluctuate significantly in facilities with low transfer volumes.

Frequently Asked Questions About Fertility Treatment in Tokyo

✅ What are the key points for choosing a fertility clinic in Tokyo?

When choosing a fertility clinic in Tokyo, you should check not only the pregnancy rate but also the live birth rate for your age group and the number of egg retrievals, ICSI procedures, and frozen embryo transfers performed.

Additionally, it is important to compare factors such as desired treatment methods, travel time, clinic hours, and ease of booking to choose a clinic that is easy to visit consistently.


✅ What is the difference between pregnancy rate and live birth rate in fertility treatment?

The "pregnancy rate" published for fertility treatments varies in its definition of pregnancy depending on the facility and the data.

The main criteria include the following:

Biochemical pregnancy
This is the stage where hCG is detected via urine or blood tests, resulting in a positive pregnancy test. Even with a positive test, the pregnancy may end before a gestational sac is confirmed via ultrasound.

Clinical pregnancy (gestational sac confirmation)
This is the stage where a gestational sac is confirmed via ultrasound. In the Japan Society of Obstetrics and Gynecology (JSOG) ART statistics, a cycle where a gestational sac is confirmed is counted as a "clinical pregnancy," and biochemical pregnancies with only a positive test are not included.

Heartbeat confirmation
This is the stage where a fetal heartbeat is confirmed via ultrasound after the gestational sac is confirmed. Some facilities publish a heartbeat confirmation rate in addition to the gestational sac confirmation rate.

Live birth rate
The percentage of embryo transfer cycles that result in a live birth.

Therefore, when comparing clinic treatment outcomes, it is important not to look only at the "pregnancy rate" figure, but to confirm which stage—hCG positive, gestational sac confirmation, or heartbeat confirmation—is being counted as a pregnancy.

Also, the figures change depending on the denominator, such as per transfer cycle, per egg retrieval cycle, or per patient. Pregnancy rates and live birth rates with different calculation conditions cannot be compared simply.


✅ Are clinics with a higher number of treatments more recommended?

While a high number of treatments indicates that many egg retrievals and embryo transfers are performed at that clinic, you cannot judge the likelihood of pregnancy based on the number of cases alone.

When comparing fertility clinics, it is recommended to check both the number of treatments and the live birth rate by age group.


✅ Where can I check the track record of fertility clinics?

You can check the number of egg retrievals, ICSI procedures, and frozen embryo transfers at fertility clinics using resources such as the medical institution search provided by the Children and Families Agency.

If a clinic publishes its treatment outcomes on its official website, be sure to check the target age, the reporting period, and whether they are listing pregnancy rates or live birth rates. Figures with different calculation conditions cannot be compared simply.


Choose a fertility clinic in Tokyo by checking their public track records

There are many fertility clinics in Tokyo, but the number of treatments and birth rates vary by facility.

The 5 clinics introduced here have a certain birth rate for frozen embryo transfers in patients aged 35-39, and they are clinics where you can verify the number of egg retrievals, ICSI procedures, and frozen embryo transfers performed.

However, birth rates are also influenced by the patient's age, treatment history, and the condition of the transferred embryos. Do not decide based on public data alone; please compare them while also considering your desired treatment methods, commuting distance, and clinic hours.
