My appointment was at 11:30, but the examination did not take place until around 12:30. The wait felt somewhat long, and I hope this improves.
I also wrote ‘no sexual experience’ on the questionnaire, but they did not confirm this before the ultrasound and performed a transvaginal ultrasound. It was more painful than I expected and surprised me🥲
I think I would have felt more at ease if they had explained it clearly beforehand.

Several AIH cycles, 1 egg retrieval, 2 embryo transfers, then transferred to another hospital.
Egg retrieval and transfers cost about 300,000 yen in total and were covered by insurance.
As other reviews say, the doctor was kind.
However, I was very disappointed by the doctor's reaction to the transfer result.
The embryo was graded 4AA.
I had the transfer using the SEET method, but the result was negative.
The doctor held his forehead, stared dejectedly at the computer, and asked, ‘Why?! It was a 4AA embryo with about a 70% success rate. Why?’ This made me even more anxious and wonder whether something was wrong with my body.
The doctor may have been trying to empathize with me, but his reaction made the situation feel truly terrible.
When the second implantation result was negative, I asked whether I should undergo various tests. I was told, ‘Testing will not improve the pregnancy rate, so you should think about whether you want to do it.’ I did not know what to do next. I was too inexperienced at the time, and I do not think this clinic suited me.
After transferring hospitals, I also found the administrative staff's attitude very poor.
The nurses could sometimes be very inflexible.
When I mentioned that one bandage for my self-injections was missing, they merely said, ‘Oh, sorry,’ in a flat voice.
10/06/2025
Every time I went, the disinfectant at the entrance and in the restroom was empty. There was never any toilet-seat disinfectant. The nurses were arrogant.
04/06/2025
I graduated from the clinic.
I went there for testing and also received contraceptive pills subsidized by the city. The doctor took great care of me during later consultations.
Everyone was skilled at drawing blood, the hospital was clean, appointments were easy to schedule, and the relatively long opening hours were very helpful.
I wish Dr. Tanaka could continue seeing me after I become pregnant. It would be wonderful if he could provide care from prenatal checkups through contraception.

We progressed from timed intercourse to IVF and became pregnant on the first attempt.
The doctors were very kind and always supported me warmly, even when I was struggling, which helped me feel more positive.
The nurses, receptionists, and all other staff were also very courteous and reassuring.
I appreciated being able to make appointments on weekends or relatively late on weekdays, which allowed me to attend while balancing work.
I safely graduated at the end of April and am now 12 weeks pregnant.
Thank you very much for your help.

I received infertility treatment here. The doctors, nurses, receptionists, and embryologists were all very kind and politely explained anything I did not understand, allowing me to attend appointments with peace of mind. During IVF, I was very nervous about the egg retrieval, but a nurse's gentle words helped me through it. I was also nervous during the embryo transfer, but the nurse pointed to the monitor and explained everything, helping me relax. Ultimately, after a positive test, the fetal heartbeat was confirmed and I successfully graduated from the clinic. I am glad I chose this clinic and would recommend it to anyone else struggling with infertility treatment.
01/07/2025
Dr. Tanaka is very patient, gentle, and skilled. We succeeded after one stimulation cycle and one transfer, and I am truly grateful.
The nurses are also very gentle.
The clinic is clean and tidy.
21/06/2025
I think the appointment system clearly does not work well.
I am very concerned about the current situation. It takes two hours just to receive documents, let alone have a consultation or examination. Booking in advance is meaningless.
Frankly, an operating system that wastes so much of patients' time is seriously flawed. Since appointments are limited, the clinic should limit the number booked rather than simply requiring appointments.
Accepting more patients than capacity allows lowers the quality of service for every patient and greatly reduces overall satisfaction.
I strongly request a serious review and improvements from the patient's perspective.
20/06/2025
I attended this clinic for about a year because it offers free fertility consultations and is close to my workplace.
Considering my age, the time we had been trying to conceive, and my previous cervical cancer surgery, I underwent testing first.
Although the infertility tests found no particular problems, I proceeded through fertility evaluation, timed intercourse, IUI, and IVF. I became pregnant after my second IVF cycle and successfully graduated.
The doctors were always kind and carefully explained anything that concerned me or that I did not understand.
The nurses also left a strong impression; they were all cheerful and friendly.
Even when I felt discouraged because I could not conceive, the hospital's relaxed and pleasant atmosphere helped me.
During egg retrieval, the embryologist explained the condition of the eggs in detail, which reassured me.
Wait times vary depending on how busy the clinic is that day, but the waiting room is comfortable and I could work there, which was convenient.
Thank you very much!
18/06/2025
We struggled for a long time, hoping to conceive, and spent many anxious days. After beginning infertility treatment at this hospital and conceiving naturally, I was overjoyed to hear my baby's heartbeat for the first time.
I am very grateful to Dr. Tanaka and all the staff for their warm support. Thank you very much.
26/07/2025
Although I arrived a little before my appointment, the doctor did not call me in until 50 minutes late. The consultation was over in 2 minutes. Very careless.
21/07/2025
🧪Tanaka Hospital helped me succeed. From the initial blood tests and medications through egg retrieval, transfer, and success, Dr. Tanaka and the medical staff were extremely patient. The doctor was gentle at every examination and fully dedicated to the patients. Thank you, Director Tanaka. I also hope everyone undergoing IVF has a smooth journey!
20/07/2025
I transferred from another hospital for infertility treatment and successfully conceived.
The doctor was very kind and worked hard to accommodate my work and personal life.
Treatment had not gone well at the other hospital, but after coming here, I began treatment and succeeded on the first attempt.
I was also deeply impressed by the exceptional expertise of Dr. Tanaka and all his staff.
Thank you very much to these wonderful people.
I will return here next time.
02/08/2025
I had always wanted to become pregnant but had difficulty conceiving, so I came here because it was near my home and the doctor was a woman.
I was anxious throughout testing and treatment, but thanks to the gentle doctor, I ultimately conceived safely. I wish I had come here sooner.
All the doctors are approachable and explain things clearly. The nurses are also very kind, skilled at drawing blood, and always quick. The receptionists are friendly as well, and I am glad I chose this hospital.
Once, when I called with a concern, they fit me in despite a full schedule, which was very reassuring.
If I need care again in the future, I will return.
Thank you very much.
01/08/2025
Dr. Tanaka has cared for me since my premarital examination. Later, when I developed irregular periods, he promptly provided appropriate treatment, allowing me to conceive successfully at an early stage.
Even when I felt anxious and uncertain about the future, Dr. Tanaka always offered patient advice. This truly encouraged me to do my best, and I am very grateful.
He always made time for me even after his own scheduled appointments. When my husband arrived late, he kindly invited me back into the examination room and personally explained my condition to him. This reassured me that I could entrust everything to Dr. Tanaka.
Not only the doctor, but also the nurses and receptionists were very kind. If I need anything in the future, I will definitely return to this clinic.
Thank you very much!
01/08/2025
I began infertility treatment at Tanaka Clinic in April this year. Dr. Tanaka carefully assessed my condition using timed intercourse, and I ultimately conceived successfully. He was very kind and explained things clearly, allowing me to undergo treatment with peace of mind. I sincerely appreciate his excellent medical skill and warm care. Thank you very much! I will definitely recommend Tanaka Clinic to anyone with the same concerns!

I successfully graduated at 9 weeks pregnant.
I had received care here since the beginning of the year, and the careful, precise examinations by Dr. Tanaka and his colleagues helped me greatly.
I am also very grateful for the laboratory's advanced technology.
Thanks to this clinic, I was able to get through an anxious period with peace of mind.
Thank you very much. 🥹

An OB-GYN near my home told me I might need to advance to the next level of treatment, so I began looking for a new hospital. The doctor at the first hospital I found was very pragmatic, and we did not connect well during the initial consultation. I did not want to end up with a poor experience, so I wanted to learn about this hospital before deciding. I found its free consultation online and attended a consultation session in December 2024. Before the session, I completed a questionnaire about the medications I was taking, and the doctor even researched them specifically. He was very helpful that day. His sincere personality reassured me, so I decided to continue at this hospital despite the distance from home. Everyone, including the staff, was very kind, and examinations and consultations went smoothly.
With ovulation-inducing medication and proper timing, I became pregnant soon after the transfer! Of course, this was thanks to accurate diagnosis and testing, but being able to attend the hospital without stress was also wonderful.
I am now eight months pregnant and due in October. Thank you very much!
25/08/2025
I conceived after treatment at Tanaka Ladies Clinic Shibuya and am now 16 weeks pregnant. I was very fortunate to succeed after just one egg retrieval and one implantation. Dr. Tanaka was very patient, and his treatment plan and medications were highly appropriate, easing my anxiety and helping me through each step smoothly. I am truly grateful to Dr. Tanaka and his team.
I became pregnant after treatment at Tanaka Ladies Clinic Shibuya. I am now 16 weeks pregnant, and everything is going well.
I believe my success after one egg retrieval and one implantation was entirely due to the doctor's careful examinations and appropriate medication. I felt at ease at every visit and am truly grateful.
22/08/2025
Convenient location near Shibuya Crossing.
The clinic primarily uses Japanese/Chinese and does not provide English forms. A staff member (I am unsure whether they were an interpreter) used a translation device to explain Chinese in another language, which took about 10–15 minutes. I was later told that patients who do not speak Japanese/Chinese need an interpreter or should find another clinic.
👉 Suitable for Japanese/Chinese speakers; not recommended for patients who rely on other languages.
21/08/2025
Although appointments are required, waits are long, and patients are often called an hour after their scheduled time.
Perhaps because the director, Dr. Tanaka, is Chinese, there are many international patients.
19/08/2025
Thank you for helping with my infertility treatment. The clinic is open on weekends and holidays, making it convenient for my partner and me to attend together. After about six months of treatment, we successfully conceived.
It was a very worrying and difficult time, but the doctor truly considered our wishes and allowed us to think about the next step without pressure.
The nurses were also very kind. Their compassion deeply moved us, and they addressed all our concerns and questions. Thank you very much.
06/10/2025
The doctor was very kind and patient, which reassured me. However, he handled the consultations, egg retrieval, and implantation alone, which must have been a tremendous burden. Perhaps for that reason, waits were long and careless errors, such as submitting the wrong documents, occurred frequently.
I was also surprised that medication prices not listed on the website were generally much higher than at other clinics. A 300 IU Gonal F Pen cost 25,000 yen as private treatment, about 10,000 yen above the average elsewhere. These differences add up.
I wonder whether IVF treatment costs are generally higher because this is a private hospital.
19/10/2025
I tried IVF for the first time at age 39, recently became pregnant, and have now graduated!
Many thanks to Dr. Tanaka and all the staff for their attentive and precise care.
Dr. Tanaka was the only person able to identify a uterine polyp that every other clinic had missed.
I am so glad I chose you. I will definitely return for help with our second child!
Thank you very much!
10/10/2025
The nurse who answered the phone was intimidating. I disliked her arrogant manner.
04/10/2025
I received treatment here for infertility while trying for my first child. I was over 40 and did not expect such a quick result, but the first transfer succeeded. I was very satisfied with Dr. Tanaka's retrieval and transfer skills, the embryologist's expertise, and the nurses' attentive care. I underwent treatment with peace of mind. Because the clinic is busy, weekday evening appointments were sometimes difficult to obtain. However, the low-stimulation approach required fewer visits, allowing me to balance work and life. I am now considering a second child and hope to receive treatment here again.
24/10/2025
The doctor was welcoming, the service was attentive, and the medical care was precise. The reception staff were also polite and left a strong impression. I am truly grateful.
24/10/2025
I booked a preconception checkup here. The doctor was kind, and Saturday consultations are convenient. Recommended.

I began treatment in July, and the first embryo transfer was successful. The environment and service were excellent, and Dr. Tanaka is responsible and highly skilled. Thank you very much!
05/11/2025
This is an excellent hospital.
I had only one embryo transfer and was successfully discharged. I am now four months pregnant and extremely grateful.
Because this was my first fertility clinic, I was nervous at first. However, Dr. Tanaka, the nurses, receptionists, and everyone I met were polite and friendly, so I felt confident entrusting my treatment to them.
The hospital is also clean and tidy, with a large workspace, allowing me to balance treatment with a busy job.
If a friend were struggling with infertility, I would definitely recommend this hospital.
If I consider a second child in the future, I will certainly choose this hospital again.
Thank you very much!
04/11/2025
I did extensive research before choosing a hospital and ultimately selected Tanaka. It worked on the first attempt, and every step went very smoothly. It was wonderful👍🏻Director Tanaka is especially kind.

Tanaka Women's Clinic
To Dr. Tanaka and all medical staff,
Thank you for your help.
After three intrauterine inseminations, we finally became pregnant.
I sincerely appreciate your guidance and support.
Because my wife was in poor health, we chose intrauterine insemination rather than IVF to minimize the strain on her.
We had previously visited a clinic in Sendagaya, but its treatment and care made us anxious, leaving both my wife and me physically and emotionally exhausted.
In those circumstances, we were drawn to reviews of Tanaka Women's Clinic that mentioned the director's personality and decided to seek care here.
Once we visited, the medical staff's patient, detailed explanations and warm, sincere service allowed my wife to undergo treatment with confidence.
The reception staff were also very friendly, and we never felt stressed during visits.
If a friend or acquaintance were trying to conceive, I would certainly recommend your clinic.
My husband and I are both very happy to have found such a wonderful clinic.
Thank you again for your help.
We look forward to your continued support.
We sincerely thank you.
25/11/2025
This hospital is wonderful.
I had many questions and concerns about infertility treatment, but the doctors, nurses, and receptionists were all very kind and explained everything patiently and thoroughly until I was fully satisfied.
I recommend Tanaka Women’s Clinic to anyone considering infertility treatment.
27/12/2025
I became pregnant after just one embryo transfer at Shibuya Tanaka Women's Clinic! I am now 9 weeks pregnant ✨ Thanks to the doctor's expertise and the staff's attentive care, my transfer went smoothly. I am very glad I chose this clinic. Thank you so much!
26/12/2025
Dr. Tanaka is extremely gentle, kind, and patient.
She listens carefully to patients' concerns and anxieties without dismissing them, making them feel respected and understood.
During appointments, she explains the condition thoroughly and offers thoughtful reassurance, making me feel as comfortable as I would with family.
I highly, highly recommend her.
Dr. Tanaka is extremely kind and gentle, and she truly listens to her patients’ concerns with great patience and care.
She takes the time to understand what the patient is going through and offers warm reassurance, which makes you feel respected and at ease.
Her explanations are clear and thoughtful, and the overall experience at this clinic is very comforting.
I highly recommend this gynecology clinic to anyone looking for a doctor who is both professional and compassionate.
25/12/2025
Special thanks to Dr. Tanaka for her consistently kind treatment and care. The professionalism and comfort are among the best in Tokyo. The experienced nurses were exceptionally careful and thoughtful at every visit, easing much of my anxiety and tension. I transferred from another clinic after five unsuccessful embryo transfers, and my first transfer with Dr. Tanaka succeeded. I am truly grateful to Dr. Tanaka, and the laboratory's blastocyst culture techniques are excellent. Dr. Tanaka speaks Chinese, and some nurses also speak Chinese. They are very welcoming to Chinese patients, making communication easy. The clinic environment is also excellent. I sincerely recommend this clinic.
24/01/2026
I chose this clinic for infertility treatment because the director is highly experienced, the clinic has a strong pregnancy-rate record, reviews described the director’s wonderful character, and, because the clinic had opened fairly recently, appointments were said to be easy to schedule.
I became pregnant after my first IVF transfer and am now 7 months pregnant. For context, we skipped IUI and proceeded directly to IVF.
The director is a wonderful female physician—very kind, warm, and almost motherly.
When my husband and I attended our first appointment, I was impressed that she asked him, in essence, whether he was prepared to take an active role in raising a child.
When I told her about my preexisting mental health condition and psychiatric care, she said she wanted to coordinate with my psychiatrist and did so. This allowed me to discuss my medications and gave me peace of mind. Few doctors go this far, and I found her exceptionally thorough.
At every visit, she asked whether I had any other concerns, answered questions in detail, and resolved my doubts and anxiety.
When I returned at 7 months pregnant to renew storage for my frozen embryos, she asked whether everything was going well and happily rubbed my belly with both hands. I was delighted.
The reception staff answer questions carefully, and all the nurses are friendly and kind. The embryologist also explains everything thoroughly and, like the doctor, asks whether you have any questions.
Depending on the day, a visit can take about 2 hours from arrival through payment. However, weekend and late-evening appointments are available, which was very helpful while working during infertility treatment. Appointments are easy to book through the app.
Thanks to them, treatment went smoothly and I became pregnant without the stress of treatment-related anxiety.
It is such a wonderful clinic that, honestly, I almost do not want to tell anyone about it, haha.
Thank you to the doctor and every staff member. I expect to return when we try for a second child and look forward to your care again.
23/01/2026
I am usually afraid of seeing doctors, especially gynecologists, and get very nervous, but my overall experience at this hospital was excellent. Fortunately, limited Japanese was not a problem because Director Tanaka speaks excellent Chinese 👍. The examination was also very gentle 👍, and the diagnosis came quickly and was explained in detail. A wonderful visit ☺️. Highly recommended!

Last March, I began considering infertility treatment. After researching, I ultimately chose this clinic. I selected it not only for the doctors’ expertise but also for its advanced equipment. Appointment times could also be arranged around my schedule, which was very convenient. Everyone, from Dr. Tanaka to the nurses, was kind and made me feel at ease during treatment. After one egg retrieval and one transfer, I became pregnant and had my own baby. I completed treatment successfully and recently delivered a healthy baby. It is all thanks to Dr. Tanaka. I am truly grateful. Thank you!

I officially began treatment at Tanaka Women’s Clinic Shibuya IVF Center in January 2026 and am now 9 weeks pregnant. I am truly delighted. They understood my wishes, and these are my impressions:
① Primary care clinic
Early in my fertility journey, I had been pregnant several times and spent six months trying at another IVF clinic without a satisfactory outcome. We ultimately chose Tanaka Women’s Clinic because of its advanced IVF technology and safe sex-selection interventions.
② Technical expertise
The director of Tanaka Clinic is dedicated and patient, gives each patient time, creates appropriate treatment plans, and is meticulous. During blood draws, the clinicians were gentle and attentive, and they offered great encouragement before and after egg retrieval and transfer. The embryology laboratory staff were also dedicated, patient, and understanding of my anxiety.
Overall impression: “The clinic is scientifically managed, respectful, and does not rush its work.”
Thank you for all your help from infertility treatment through IVF and ultimately a successful pregnancy.
Because this is my first pregnancy at an older age, I had many concerns. Thanks to the director’s precise, calm judgment and detailed explanations at every visit, I felt secure through the end.
Treatment and medication decisions were always based on medical evidence and did not cause excessive anxiety. I was impressed by how clearly he explained what mattered at each stage.
At every visit, he carefully checked embryonic development and the fetal heartbeat. This thorough follow-up was extremely important to me.
The nurses and staff were kind, and the clinic’s warm atmosphere gave me emotional support.
I am truly glad I chose this clinic. I would gladly recommend it to anyone considering infertility treatment or IVF, especially those anxious about their age.

A friend who works in healthcare recommended this clinic to me.
There were times when I felt anxious during treatment, but Dr. Tanaka's calm explanations and the staff's attentive care supported me again and again. I was able to continue treatment with peace of mind.
Our third transfer was successful, and I am truly grateful. I am so glad I continued to trust both Dr. Tanaka and myself.
This review is late, but I wanted to express my gratitude.
I wish Dr. Tanaka and the entire staff continued success.
I also hope everyone working with Dr. Tanaka graduates from the clinic soon!

I became pregnant through IVF.
From timed intercourse through IVF treatment, I communicated fully with the doctors, and they respected my pace. Ovarian stimulation and egg retrieval placed almost no physical strain on me.
This is a truly wonderful clinic.
My heartfelt thanks to every member of the staff. Thank you so much!
27/01/2026
Although I had only recently arrived in Japan, it was very helpful to find a hospital where I could communicate in Chinese. The doctors here are also patient and responsible.
11/01/2026
I became pregnant after my first IVF cycle. Thank you so much!
Appointments often ran late, but I assumed this happens at every hospital, so it did not bother me much.
The doctor was candid and explained only what was necessary, clearly and concisely.
I had worried about pain, but the egg retrieval was performed without anesthesia and was almost painless, which shows how skilled they are.
The nurses were also kind and reassuring. Thank you very much!
21/02/2026
I successfully became pregnant through timed intercourse.
I had tried timed intercourse three times at other hospitals and transferred here hoping to find a hospital where I could continue treatment if I later needed IVF. I succeeded on my first timed-intercourse attempt here.
Both doctors were kind, and the relaxed atmosphere made it easy to ask questions at any time, which was very reassuring.
The receptionists and nurses were also very friendly.
I had worried that the vaginal exam would be painful, but the experience was surprisingly good and much less painful than I expected.
I am truly grateful.
Thank you very much.
24/03/2026
I conceived successfully through timed intercourse and soon graduated from the clinic.
The director and all the staff were warm and kind, helping me feel relaxed at every visit.
I could ask anything, and they always listened patiently and kindly without becoming annoyed, which was very reassuring.
I received a referral letter and will transfer to another clinic, but honestly, I wish I could remain at Tanaka Women's Clinic until delivery. It is truly a wonderful clinic.
Thank you so much for everything.
19/03/2026
I initially visited for a premarital health screening.
The results were normal, but because I wanted to become pregnant as soon as possible, we continued with timed intercourse.
Ultimately, I became pregnant on my second IVF attempt, for which I am very grateful.
There are no part-time physicians, so you see the same doctor every time.
Dr. Tanaka is very kind and understanding. He patiently addressed my anxiety, allowing me to undergo infertility treatment with confidence. The receptionists and nurses were also friendly and welcoming, which was reassuring.
The embryologist also explained the eggs, sperm, and embryos in detail every time, which was very helpful.
The only drawback is the long wait, but the waiting room is spacious and comfortable with good seating. The clinic is also open on weekends, making it easier to balance work and appointments.
Appointments can be booked easily through the website or app.
Patients are called by number in the clinic to protect privacy.
I am glad I found this hospital.
Once again, my sincere thanks to Dr. Tanaka, the nurses, and the embryologists.
I would like to return for care when trying for my second child.
11/03/2026
Because I live overseas, I scheduled an appointment about two weeks before my visit and completed a detailed online questionnaire in advance, hoping to learn what testing or treatment might be possible during my limited stay in Japan. I clearly described my medical history, current fertility situation, and length of stay, and said I wanted to discuss any options available during that time.
However, on the day of the appointment, no doctor examined me or provided an explanation. Instead, a nurse told me, “Unless you stay in Japan for at least one menstrual cycle, our clinic cannot offer you any services.” That was all. I did not even meet the doctor.
Because I had explained my situation in detail beforehand, I believe the clinic should have told me before the appointment if it could not accommodate me during my stay. I was very disappointed because my time in Japan after returning from overseas was extremely limited.
In a response to another customer, the clinic stated, “The doctor will personally conduct the initial consultation and explain your condition. Meeting with the doctor is considered a medical examination.” However, I did not meet the doctor at all. I therefore do not understand why I was charged an initial consultation fee.
If you are traveling from far away or have limited time, it is best to confirm in advance whether the doctor can accommodate your schedule.
09/03/2026
This was my first infertility treatment, and I proceeded directly to in vitro fertilization. Implantation succeeded on the first attempt. After the pregnancy test was positive, I was so happy to see Dr. Tanaka's excited expression when I entered the consultation room and hear him congratulate me repeatedly. Although I am about to graduate from this hospital, I would definitely choose their services again.
14/04/2026
I recommend this hospital to anyone undergoing infertility treatment: stop blaming yourself.
I began treatment because of low AMH. After three embryo transfers at another hospital, implantation occurred, but each ended in an early miscarriage. I transferred here and conceived on the first transfer, ultimately delivering successfully.
At my previous hospital, fertilization occurred in vitro, but few embryos reached the blastocyst stage. Four retrievals produced 13 eggs, only 3 of which were suitable for transfer, and none was particularly high quality. Because my husband had no identified issues, I blamed my eggs.
Here I learned that centrifuging the sperm had caused DNA damage that prevented development to the blastocyst stage. The clinic used a selection method without centrifugation, and all 3 retrieved eggs became high-quality blastocysts. The healthiest-looking embryo was transferred, implanted on the first attempt, and resulted in a healthy baby.
I was not pressured into unnecessary tests, and medication was minimized, reducing the burden on my body. Because of my low AMH, other hospitals used medium to high medication doses to stimulate follicles. Under Dr. Tanaka, reducing stimulation did not reduce the number of eggs retrieved and, in my view, improved their quality. I strongly recommend this hospital to anyone being treated for low AMH.
The embryologists are highly skilled. They successfully cultured my eggs and made my previous painful experiences feel like a distant memory. This hospital clearly has an expert team.
The nurses were also very considerate. When I felt anxious during egg retrieval, they held my hand, which deeply moved me.
The doctor is highly skilled, and egg retrieval and embryo transfer were relatively painless. I realized that even with the same fertility treatment, outcomes can differ greatly depending on the doctor's approach and how well it suits the individual. If treatment has left you distressed and discouraged, I strongly suggest visiting this hospital before blaming yourself.

Today, my wife successfully completed treatment at this clinic.
This was her first IVF attempt, and fortunately she became pregnant on the first try. We were both surprised and overjoyed.
Watching my wife continue treatment while working, I sincerely appreciated the doctor's precise diagnosis and use of advanced technology to complete treatment in the shortest possible time.
The doctor's explanations were clear enough that I could confidently support her treatment. The clinic staff were also warm and attentive; after each visit, my wife would say, “I'm so glad we chose this clinic.”
On the difficult road of infertility treatment, finding such a trustworthy partner—a hospital—was our family's greatest blessing.
I give this clinic my highest recommendation to anyone sincerely hoping to conceive. Thank you very much!
09/04/2026
I visited the clinic because I was concerned about premenstrual syndrome and a hormonal imbalance.
I was somewhat anxious before the examination, but the doctor was very kind and explained everything thoroughly, which reassured me. The ultrasound and blood tests went smoothly, and the results were clearly explained.
I am glad to have gained a comprehensive understanding of my health. Thank you very much!

Everything went smoothly from the initial testing through confirmation of the baby's heartbeat.
The attending physician was very courteous and kind, and the service was impeccable.
I was very satisfied with the sense of safety and the level of professionalism.
My first IVF attempt succeeded. Everything went smoothly.

Two weeks ago, the doctor could not identify even the basic cause and only wrote a referral to a larger hospital, which was already disappointing. Worse, when I came to collect the referral today, the front desk publicly ordered my quiet 14-year-old child to wait outside. Making a minor wait alone outdoors shows no concern for safety or basic common sense. Both the medical care and service were poor, with no empathy. A terrible experience.

The doctor was extremely kind and reassuring and encouraged me at every visit! Everyone there always treated me thoughtfully, so I felt comfortable entrusting my care to them.
After three timed-intercourse cycles and three intrauterine inseminations at another clinic, I transferred here with IVF in mind. Because my AMH was low, I planned to move to IVF after two more IUIs, but I conceived on my second IUI after transferring! Before changing clinics, I thought IUI results might not differ much between clinics, but I was thrilled to achieve this result thanks to the doctor.
A heartbeat was confirmed at 7 weeks, and I am truly delighted! Thank you so much!

I spent a year at this clinic without becoming pregnant, so I transferred elsewhere. I cannot assess the new clinic's results because my own health issues, as well as embryo culture techniques, may have affected the outcome. The clinic director, Dr. Tanaka, is kind, but the receptionists and nurses—especially several nurses in their 50s—were arrogant, condescending, and unfriendly, upsetting me repeatedly. I can therefore give only two stars.
*Advantages
- Waits are not long, up to about an hour and a half depending on the day.
- Clinic director Dr. Tanaka is very attentive and skilled at internal examinations.
- The clinic mainly uses low- to moderate-stimulation protocols to minimize physical strain.
- Convenient access from Shibuya Station.
- Late and weekend appointments are available.
*Disadvantages
- Egg retrieval is performed without anesthesia, causing severe pain.
- We received only a one-minute explanation, and I had to pay a consultation fee for my husband even though he received no treatment. The clinic I transferred to does not do this.
- The nurses' procedures and explanations often seemed to vary by person and were frequently inadequate. Even during the excruciating egg retrieval, they offered no support and instead rushed me. I remember them all being cold.

I underwent IVF at Tanaka Ladies Clinic and became pregnant on the first attempt. I was overjoyed because I never imagined everything would go so smoothly.
I sincerely appreciate the doctor's excellent skill and attentive guidance. The nurses' warm care was also very reassuring.
I especially thank Dr. Tanaka, who was always kind and encouraging and greatly eased my anxiety during treatment.
I sincerely hope everyone who chooses Tanaka Ladies Clinic achieves the same success.

I am a student from Taiwan. I was very anxious about seeing a gynecologist in Japan for the first time. Reviews of nearby clinics were mixed, and I briefly considered settling for one, but I was fortunate to find Tanaka Gynecology Clinic in Shibuya!
The clinic is conveniently located less than a 5-minute walk from Shibuya Station, which was especially helpful on a rainy day like today. The interior is modern and clean, just like the website photos, creating a relaxed and comfortable atmosphere.
Dr. Tanaka was very professional. The examination was thorough and gentle, allowing me to discuss all my concerns comfortably. I highly recommend this clinic to anyone anxious about finding medical care in Japan!
I am currently studying in Taiwan and have received gynecologic care in Japan. I previously received care in Japan for gynecologic concerns. This clinic is not open to the public and is close to home. After reviewing landlord comments and information on government websites, I visited for the first time today.
The clinic matches its website: modern and very clean, with consistent information and presentation. During my appointment with Director Tanaka, the director showed professionalism, attention to detail, and considerate care that made me feel at ease. I highly recommend this clinic!

The doctors and staff were very kind, and their examinations and explanations were thorough and attentive, making me feel at ease at every visit. Treatment was often anxiety-provoking, but they always stayed by my side, which was very reassuring.
I am deeply grateful to have completed treatment successfully. Thank you so much!

The doctors and staff always treated me warmly, allowing me to attend appointments with confidence.
I am especially grateful to my physician.
I often felt anxious during treatment and worried even about small matters, but each time, my doctor listened carefully and explained everything clearly.
At every appointment, the doctor’s words reassured me and helped me continue treatment with a positive attitude.
I believe I was able to graduate successfully thanks to my doctor and everyone at the clinic.
Thank you very much.

The hospital has a pleasant environment, and the director is very approachable. Thanks to everyone’s cooperation, I was able to graduate successfully. Thank you very much!

I had long suffered from menstrual pain without improvement, but since receiving treatment at this hospital, I have had no pain at all this month. I am truly grateful to the doctors!
29/05/2026
The clinic is very clean, and the explanations are detailed, so I believe it is a clinic patients can visit with confidence.

I am incredibly grateful to be having a baby.
Thank you so much.

After four rounds of intrauterine insemination, I began in vitro fertilization (IVF). After my second egg retrieval and embryo transfer, I became pregnant, and a fetal heartbeat was recently confirmed.
I have not been to any other hospitals, so I cannot compare them, but this hospital was excellent for me. Not only was I pleased with the outcome, but the doctor, nurses, embryologists, and everyone else had wonderful personalities, teamwork, and professional skills.
I imagine many people reading this review are looking for the right hospital. I am writing this in the hope that it will be helpful.
• About the doctor
The doctor was very approachable, always encouraged me, and patiently answered all my questions. I will never forget how he held my hand and congratulated me after my successful embryo transfer.
• About the nurses
Some reviews say the nurses have a poor attitude. While some of them are indeed quite casual, I felt close to them and found them friendly. (Do you know how some people can seem overly formal or distant? It was the opposite of that.)
They explained the self-injection process very carefully. During my egg retrieval, they held my hand from above, which reassured me because I was nervous.
However, while lying on the bed during the egg retrieval, I could clearly hear the nurses talking in the blood collection room. I think this could make some people uncomfortable, and because their conversation was so easy to hear, they should be mindful of what they say. Patients are often nervous before and after egg retrieval, so it would be better to keep things quiet.
One nurse was also exceptionally skilled at drawing blood. It was the first completely painless blood draw I had ever experienced.
• About wait times and visit duration
Waits are usually longer on weekends, but even then, 3 hours is generally enough unless it is the day of an egg retrieval or embryo transfer. I often booked the first afternoon appointment on a weekday and could usually leave in about an hour and a half. Honestly, I think wait times are similar at any hospital, so if you dislike waiting, I recommend booking the first appointment in the morning or afternoon.
• About egg retrieval
This hospital generally does not use anesthesia. There is some pain, but it was nowhere near as severe as I had heard. It hurt, but not as much as I had imagined. It was not a sharp, direct pain, but more of a dull ache similar to menstrual cramps.
I found the tubal patency test more painful. (My right fallopian tube was slightly blocked, so it was very painful at first. The pain eased once the blockage was cleared. I was told that people without a blockage do not experience pain.)
Because anesthesia is not required, you can go home sooner and avoid the cost of anesthesia. If you do need anesthesia, you can discuss it with them.
• About the embryologist's explanation
You can speak directly with the embryologist after egg retrieval and before a frozen fertilized egg is thawed and transferred. At the egg retrieval, they carefully explain the condition of the eggs and the planned fertilization method. When I was unsure whether to choose conventional insemination or intracytoplasmic sperm injection (ICSI), they presented several options and explained their recommendation and the alternatives, allowing me to proceed with confidence.
Before the transfer, they also carefully explain the condition of the thawed embryo, whether assisted hatching was performed, and how the embryo has developed. They told me the embryo was in excellent condition, which reassured me and gave me more confidence about proceeding with the transfer.
• About the large number of international patients: As other reviews mention, perhaps because the doctor is Chinese, the clinic has many international patients. I saw international patients in the waiting room at every visit, but throughout my year of treatment, I never felt uncomfortable. It may depend on the appointment time, but I do not think it is anything to worry about.
• In summary: I am very happy that I received infertility treatment at such an excellent hospital and became pregnant.
Thank you so much!
If I decide to have a second child in the future, I will choose this hospital again.

The clinic is clean, tidy, and well maintained. The waiting room has electrical outlets and a water dispenser.
The doctor, nurses, and staff are all warm and friendly, which made me feel at ease.
Thank you so much!

I graduated from Dr. Tanaka's IVF and Reproductive Medicine Department yesterday 🧪🎉 It worked on the first try. Truly a miracle worker! Thank you to Director Tanaka and the entire medical team for their patient care and support. I transferred here after two failed attempts at Ginza Oak Clinic 😭 This time I truly found an excellent doctor—a source of pride for the Chinese community in Japan 🇯🇵. From ovarian stimulation and egg retrieval to embryo transfer, Dr. Tanaka personally handled every examination. His technique is superb 👍🏻 Of the 3 eggs retrieved, 3 were cultured, resulting in 3 high-quality blastocysts. The first transfer was successful!! My heartfelt thanks to Director Tanaka 🙏🏻🌹

I underwent treatment at age 39 and am now pregnant with my first child.
This was my second time seeing Dr. Tanaka, and she was a much better fit for me this time.
I underwent IVF once at my previous clinic and five times at Dr. Tanaka's clinic. After six attempts in total, I finally became pregnant.
Given my age, I tried nearly every advanced treatment available. Despite having good placental function, I experienced repeated biochemical pregnancies. I was close to losing hope, but Dr. Tanaka was always kind and supportive, which gave me tremendous reassurance.
She was like a second mother to me. When I graduated from the clinic, I had mixed feelings—I was both happy and sad.
Getting to my previous clinic was inconvenient, but even after more than a year of treatment at Dr. Tanaka's clinic, I never found it tiring.
The receptionists and nurses created a warm, comfortable atmosphere.
I chose this clinic because it was conveniently located near both my home and workplace, and it proved to be absolutely the right choice!
Looking back, I was a terrible patient at times and even went for egg retrieval while hungover on occasion. I was certainly not a model patient, but thanks to consistently taking supplements and probiotics from a certain point onward, I am now approaching 20 weeks of pregnancy! 🤰
Dr. Tanaka's final comment—“If you consider having a second child, perhaps I will see him or her when you are around 41?”—really stayed with me. I had never considered it before, but if I return to Dr. Tanaka's clinic, perhaps I could try again!
I hope I have the opportunity to see you again someday.
Thank you so much! 😊

I used to be a patient here, but growing distrust led me to transfer to another clinic.
1. Lack of consideration for privacy
I frequently heard staff chatting among themselves and saying other patients’ names in the waiting room. Because I was undergoing treatment and was emotionally sensitive at the time, I worried that my personal information was being handled the same way, which caused me considerable stress.
2. Poor coordination
There appeared to be no information sharing between the doctors and nurses. An explanation I had just received would not be passed along a few minutes later, and different nurses sometimes gave different explanations.
It is very disappointing because the clinic was conveniently located. I have now transferred to another hospital where I feel comfortable receiving care.

I received care here for my first IVF treatment. The doctor was very experienced, and the examinations and explanations were thorough and reassuring. A mild stimulation protocol was selected to suit my condition. Although only 1 eggs were retrieved, I was able to become pregnant with those precious 1 eggs. I believe this doctor recommends treatment tailored to each patient. Thank you very much. I can confidently recommend this clinic to anyone struggling with infertility.

I married in my late 30s.
Wanting to conceive as soon as possible, I began infertility treatment.
The first clinic I attended was beautiful and sophisticated, but it somehow felt impersonal, and the consultations seemed mechanical and administrative.
At the time, I was also visiting an acupuncture clinic specializing in infertility. That was where I was introduced to Dr. Tanaka!
Her career was impressive, of course, and after attending an information session and speaking with her personally, I came away with an excellent impression!!
She is warmhearted and feels like ‘everyone’s mother.’
I can comfortably ask her anything, even questions I might otherwise hesitate to raise.
I also had an opportunity to meet with an embryologist, who was very caring.
The nurses are direct, cheerful, energetic, and full of life.
Thanks to them, I had a healthy baby after my １ embryo transfer!
I am truly filled with gratitude!
I wholeheartedly and proudly recommend Tanaka Ladies Clinic Shibuya.
Thank you so much for always greeting me with such wonderful smiles.

I received treatment at this clinic and gave birth safely last month.
After trying timed intercourse and intrauterine insemination, I chose IVF and became pregnant after my first egg retrieval.
I was worried about pain because egg retrieval is generally performed without anesthesia, but I actually felt almost no pain.
It was not a sharp, needle-like pain, but a mild, dull pressure that was entirely tolerable. It was even easier than having blood drawn or receiving an injection.
I also appreciated that the entire treatment remained as close to a natural process as possible, without excessive medication, so it did not affect my physical condition.
All the staff were very kind and patiently answered all my questions.
I highly recommend this clinic to anyone considering infertility treatment. Thank you very much!

This is a rare gynecology clinic where a Chinese female physician with a doctorate from the University of Tokyo offers consultations in Chinese. The consultations are detailed and attentive, the examinations cause very little discomfort, and the clinic has new, clean equipment. Test results are also explained very clearly and understandably. Highly recommended for women living in Japan!
